Polygons on ACT Math Geometry Formulas and Strategies

Polygons on ACT Math Geometry Formulas and Strategies SAT / ACT Prep Online Guides and Tips Questions about both circles and various types of polygons are some of the most prevalent types of geometry questions on the ACT. Polygons come in many shapes and sizes and you will have to know them inside and out in order to take on the many different types of polygon questions the ACT has to offer. The good news is that, despite their variety, polygons are often less complex than they look; a few simple rules and strategies are all that you need when it comes to solving an ACT polygon question. This will be your complete guide to ACT polygons- the rules and formulas for various polygons, the kinds of questions you’ll be asked about them, and the best approach for solving these types of questions. What is a Polygon? Before we go to polygon formulas, let’s look at what exactly a polygon is. A polygon is any flat, enclosed shape that is made up of straight lines. To be â€Å"enclosed† means that the lines must all connect, and no side of the polygon can be curved. Polygons NOT Polygons Polygons come in two broad categories- regular and irregular. A regular polygon has all equal sides and all equal angles, while irregular polygons do not. Regular Polygons Irregular Polygons A polygon will always have the same number of sides as it has angles. So a polygon with nine sides will have nine angles. The different types of polygons are named after their number of sides and angles. A triangle is made of three sides and three angles (â€Å"tri† meaning three), a quadrilateral is made of four sides (â€Å"quad† meaning four), a pentagon is made of five sides (â€Å"penta† meaning five), etc. Many of the polygons you’ll see on the ACT (though not all) will either be triangles or some sort of quadrilateral. Triangles in all their forms are covered in our complete guide to ACT triangles, so let’s move on to look at the various types of quadrilaterals you’ll see on the test. Barber shop quartets, quadrilaterals- clearly the secret to success is in fours. Quadrilaterals There are many different types of quadrilaterals, most of which are subcategories of one another. Parallelogram A parallelogram is a quadrilateral in which each set of opposite sides is both parallel and congruent (equal) with one another. The length may be different than the width, but both widths will be equal and both lengths will be equal. Parallelograms are peculiar in that their opposite angles will be equal and their adjacent angles will be supplementary (meaning any two adjacent angles will add up to 180 degrees). Most questions that require you to know this information are quite straightforward. For example: If we draw this parallelogram, we can see that the two angles in question are supplementary. This means that the two angles will add up to 180 degrees. Our final answer is F, add up to 180 degrees. Rhombus A rhombus is a type of parallelogram in which all four sides are equal and the angles can be any measure (so long as their adjacents add up to 180 degrees and their opposite angles are equal). Rectangle A rectangle is a special kind of parallelogram in which each angle is 90 degrees. The rectangle’s length and width can either be equal or different from one another. Square If a rectangle has an equal length and width, it is called a square. This means that a square is a type of rectangle (which in turn is a type of parallelogram), but NOT all rectangles are squares. Trapezoid A trapezoid is a quadrilateral that has only one set of parallel sides. The other two sides are non-parallel. Kite A kite is a quadrilateral that has two pairs of equal sides that meet one another. You'll notice that a lot of polygon definitions will fit inside other definitions, but a little organization (and dedication) will help keep them straight in your head. Polygon Formulas Though there are many different types of polygons, their rules and formulas build off of a few basic ideas. Let’s go through the list. Area Formulas Most polygon questions on the ACT will ask you to find the area or the perimeter of a figure. These will be the most important area formulas for you to remember on the test. Area of a Triangle $$a = {1/2}bh$$ The area of a triangle will always be half the amount of the base times the height. In a right triangle, the height will be equal to one of the legs. In any other type of triangle, you must drop down your own height, perpendicular from the vertex of the triangle to the base. Area of a Square $$l^2$$ Or $$lw$$ Because each side of a square is equal, you can find the area by either multiplying the length times the width or simply by squaring one of the sides. Area of a Rectangle $$lw$$ For any rectangle that is not a square, you must always multiply the base times the height to find the area. Area of a Parallelogram $$bh$$ Finding the area of a parallelogram is exactly the same as finding the area of a rectangle. Because a parallelogram may slant to the side, we say we must use its base and its height (instead of its length and width), but the principle is the same. You can see why the two actions are equal if you were to transform your parallelogram into a rectangle by dropping down straight heights and shifting the base. Area of a Trapezoid $$[(l_1 + l_2)/2]h$$ In order to find the area of a trapezoid, you must find the average of the two parallel bases and multiply this by the height of the trapezoid. Let's take a look at this formula in action, The trapezoid is divided into a rectangle and two triangles. Lengths are given in inches. What is the combined area of the two shaded triangles? A. 4 B. 6 C. 9 D. 12 E. 18 If you remember your formula for trapezoids, then we can find the area of our triangles by finding the area of the trapezoid as a whole and then subtracting out the area of the rectangle inside it. First, we should find the area of the trapezoid. $[(l_1 + l_2)/2]h$ $[(6 + 12)/2]3$ $(18/2)3$ $(9)3$ $27$ Now, we can find the area of the rectangle. $6 * 3$ 18 And finally, we can subtract out the area of the rectangle from the trapezoid. $27 - 18$ 9 The combined area of the triangles is 9. Our final answer is C, 9. In general, the best way to find the area of different kinds of polygons is to transform the polygon into smaller and more manageable shapes. This will also help you if you forget your formulas come test day. For example, if you forget the formula for the area of a trapezoid, turn your trapezoid into a rectangle and two triangles and find the area for each. Luckily for us, this has already been done in this problem. We know that we can find the area of a triangle by ${1/2}bh$ and we already have a height of 3. We also know that the combined bases for the triangles will be: $12 - 6$ 6 So let us say that one triangle has a base of 4 and the other has a base of 2. (Why those numbers? Any numbers for the triangle bases will work so long as they add up to 6.) Now, let us find the area for each triangle. or the first triangle, we have: ${1/2}(4)(3)$ $(2)(3)$ $6$ And for the second triangle, we have: ${1/2}(2)(3)$ $(1)(3)$ 3 Now, let us add them together. $6 + 3$ 9 Again, the area of our triangles together is 9. Our final answer is C, 9. Always remember that there are many different ways to find what you need, so don’t be afraid to use your shortcuts! Side and Angle Formulas Whether your polygon is regular or irregular, the sum of its interior degrees will always follow the rules of that particular polygon. Every polygon has a different degree sum, but this sum will be consistent, no matter how irregular the polygon. For example, the interior angles of a triangle will always equal 180 degrees, whether the triangle is equilateral (a regular polygon), isosceles, acute, or obtuse. So by that same notion, the interior angles of a quadrilateral- whether kite, square, trapezoid, or other- will always add up to be 360 degrees. Interior Angle Sum You will always be able to find the sum of a polygon’s interior angles in one of two ways- by memorizing the interior angle formula, or by dividing your polygon into a series of triangles. Method 1: Interior Angle Formula $$(n−2)180$$ If you have an n number of sides in your polygon, you can always find the interior degree sum by the formula $(n - 2)$ times 180 degrees. Method 2: Dividing Your Polygon Into Triangles The reason the above formula works is because you are essentially dividing your polygon into a series of triangles. Because a triangle is always 180 degrees, you can multiply the number of triangles by 180 to find the interior degree sum of your polygon, whether your polygon is regular or irregular. As we saw, we have two options to find our interior angle sum. Let us try each method. Solving Method 1: formulas $(n - 2)180$ There are 5 sides, so if we plug that into our formula for $n$, we get: $(5 - 2)180$ $3(180)$ 540 Now we can find the sum of the rest of the angle measurements by subtracting our known degree measure, 50, from our total interior degrees of 540. $540 - 50$ 490 Our final answer is K, 490. Solving Method 2: diving polygon into triangles We can also always divide our polygon into a series of triangles to find the total interior degree measure. We can see that our polygon makes three triangles and we know that a triangle is always 180 degrees. This means that the polygon will have a interior degree sum of: $3 * 180$ 540 degrees. And finally, let us subtract the known angle from the total in order to find the sum of the remaining degrees. $540 - 50$ 490 Again, our final answer is K, 490. Individual Interior Angles If your polygon is regular, you will also be able to find the individual degree measure of each interior angle by dividing the degree sum by the number of angles. (Note: n can be used for both the number of sides and the number of angles because the number of sides and angles in a polygon will always be equal.) ${(n - 2)180}/n$ Again, you can choose to either use the formula or the triangle dividing method by dividing your interior sum by the number of angles. Number of Sides As we saw earlier, a regular polygon will have all equal side lengths. And if your polygon is regular, you can find the number of sides by using the reverse of the formula for finding angle measures. A regular polygon with n sides has equal angles of 140 degrees. How many sides does the figure have? 6 7 8 9 10 For this question, it will be quickest for us to use our answers and work backwards in order to find the number of sides in our polygon. (For more on how to use the plugging in answers technique, check out our guide to plugging in answers). Let us start at the middle with answer choice C. We know from our angle formula (or by making triangles out of our polygons) that an eight sided figure will have: $(n - 2)180$ $(8 - 2)180$ $(6)180$ 1080 degrees. Or again, you can always find your degree sum by making triangles out of your polygon. This way you will still end up with (6)180=1080 degrees. Now, let us find the individual degree measures by dividing that sum by the number of angles. $1080/8$ $135$ Answer choice C was too small. And we also know that the more sides a figure has, the larger each individual angle will be, so we can cross off answer choices A and B, as those answers would be even smaller. (How do we know this? A regular triangle will have three 60 degree angles, a square will have four 90 degree angles, etc.) Now let us try answer choice D. $(n - 2)180$ $(9 - 2)180$ $(7)180$ 1260 Or you could find your internal degree sum by once again making triangles from your polygons. Which would again give you $(7)180 = 1260$ degrees. Now let’s divide the degree sum by the number of sides. $1260/9$ $140$ We have found our answer. The figure has 9 sides. Our final answer is D, 9. Number of Diagonals $${n(n - 3)}/2$$ It is common for the ACT to ask you about the number of distinct diagonals in a polygon. Again, you can find this information using the formula or by drawing it out (or a combination of the two). This is basically the same as dividing your polygon into triangles, but they will be overlapping and you are counting the number of lines drawn instead of the number of triangles. Method 1: formula In order to find the number of distinct diagonals in a polygon, you can simply use the formula ${n(n - 3)}/2$, wherein $n$ is the number of sides of the polygon. Method 2: drawing it out The reason the above formula works is a matter of logic. Let’s look at an octagon, for example. You can see that an octagon has eight angles (because it has eight sides). If you were to draw all the diagonals possible from one particular angle, you could draw five lines. You will always be able to draw n−3 lines because one of the angles is being used to form all the diagonals and the lines to the two adjacent angles make up part of the perimeter of the polygon and are therefore NOT diagonals. So you can only draw diagonals to n−3 corners. Now, let’s mark another angle’s series of diagonals. You can see that none of these diagonals overlap, BUT if we were to draw the diagonals from an opposite corner, we would have multiple overlapping diagonals. The adjacent angles will not overlap, but the opposite ones will. This means that there will only be half as many diagonals as the total number of angles multiplied by their possible diagonals (in other words half of n(n−3). This is why our final formula is: ${n(n - 3)}/2$ This is all the angles multiplied by their total number of diagonals, all divided by half so that we do not get overlapping diagonal lines. (Note: of course an alternative to using any form of the formula is to simply draw out your diagonals, making sure to be very very careful to not create any overlapping diagonal lines.) Just make sure you don't dizzy yourself keeping track of all your angles and diagonals. Typical Polygon Questions Now that we’ve been through all of our polygon rules and formulas, let’s look at a few different types of polygon questions you’ll see on the ACT. About half of ACT polygon questions you’ll see will involve diagrams and about half will be word problems. Most all of the word problems will involve quadrilaterals in some form or another. Typically, you will be asked to find one of three things in a polygon question: The measure of an angle (or the sum of two or more angles) The perimeter of a figure The area of a figure Let’s look at a few real ACT math examples of these different types of questions. 1. Finding the measure of an angle We know that we can find the degree measure of a regular polygon by finding their total number of degrees and dividing that by the number of sides/angles. So let us find the sum of the interior degrees of our pentagon. A pentagon can be divided into three triangles, so we know that it has a total of: 3(180) 540 degrees. If we divide this number by the number of sides/angles in a pentagon, we can see that each angle measure is: $540/5$ 108 Now, we also know that every straight line is 180 degrees. This means that we can find the exterior angles of the pentagon by subtracting the interior angles from 180. $180 - 108$ 72 We also know that a triangle's interior degrees always add up to 180, so we can find our final angle by subtracting our two known angles from 180. $180 - 72 - 72$ 36 Our final answer is C, 36. 2: Finding the perimeter of a figure We know that a square has, by definition, all equal sides. Because DC is 6, that means that ED, EB, and BC are all equal to 6 as well. We also know that an equilateral triangle has all equal sides. Because EB equals 6 and is part of the equilateral triangle, EB, AE, and AB are all equal to 6 as well. And, finally, the perimeter of the figure is made up of lines DE, EA, AB, BC, and CD. This means that our perimeter is: 6 + 6 + 6 + 6 + 6 30 Our final answer is C, 30. 3: Using or finding the area of the figure We know that the area of a rectangle is found by multiplying the length times the width, and we also know that a rectangle has two paris of equal sides. So we need to find measurements for the sides that, in pairs, add up to 24 and, when multiplied, will make a prouct of 32. One way we can do this is to use the strategy of plugging in answers. Let us, as usual when using this strategy, start with answer choice C. So, if we have a short side length of 3, we need to double it to find how much the short sides contribute to the total perimeter. $3 * 2$ 6 If we subtract this from our total perimeter, we find that the sum of our longer sides are: $24 - 6$ 18 Which means that each of the longer sides is: $18/2$ 9 Now, if one side length is 3 and the other is 9, then the area of the rectangle will be: $3 * 9$ 27 This is too small to be our area. We need the shorter side lengths to be longer than 3 so that the product of the length and the width will be larger. Let us try option J instead. If we have two side lengths that each measure 4, they will add a total of: $4 * 2$ 8 Now let us subtract this from the total perimeter. $24 - 8$ 16 This is the sum of the longer side lengths, which means we must divide this number in half to find the individual measures. $16/2$ 8 And finally, let us multiply the length times the width to find the area of the rectangle. $8 * 4$ 32 These measurements fit our requirements, which means that the shorter sides must each measure 4. Our final answer is J, 4. Now let's look at the strategies for success for your polygon questions (as well as what to avoid doing). How to Solve a Polygon Question Now that we’ve seen the typical kinds of questions you’ll be asked on the ACT and gone through the process of finding our answers, we can see that each solving method has a few techniques in common. In order to solve your polygon problems most accurately and efficiently, take note of these strategies: #1: Break up figures into smaller shapes Don’t be afraid to write all over your diagrams. Polygons are complicated figures, so always break them into small pieces when you can. Break them apart into triangles, squares, or rectangles and you’ll be able to solve questions that would be impossible to figure out otherwise. Alternatively, you may need to expand your figures by providing extra lines and creating new shapes in which to break your figure. Just always remember to disregard these false lines when you’re finished with the problem. If we create and expand new lines in our figure, we can make our lengths and sides a little more clear. We can also see why this works because our red lines are essentially extensions of the perimeter branching outwards in order to give us a clearer picture. Now, we know that, because the bottom-most horizontal line is equal to 20, the sum of all the other horizontal lines is also equal to 20. We can also see that all the vertical lines will add up to: 12 + 8 + 8 + 12 This means that our total perimeter will be: 20 + 20 + 12 + 12 + 8 + 8 80 Our final answer is B, 80. #2: Use your shortcuts If you don’t feel comfortable memorizing formulas or if you are worried about getting them wrong on test day, don’t worry about it! Just understand your shortcuts (for example, remember that all polygons can be broken into triangles) and you’ll do just fine. #3: When possible, use PIA or PIN Because polygons involve a lot of data, it can be very easy to confuse your numbers or lose track of the path you need to go down to solve the problem. For this reason, it can often help you to use either the plugging in answer strategy (PIA) or the plugging in numbers strategy (PIN), even though it can sometimes take longer (for more on this, check out our guides to PIA and PIN). #4: Keep your work organized There is a lot of information to keep track of when working with polygons (especially once you break the figure into smaller shapes). It can be all too easy to lose your place or to mix-up your numbers, so be extra vigilant about your organization and don’t let yourself lose a well-earned point due to careless error. Before you go ahead and put your polygon knowledge to the test, take a moment to bask in some much-needed Cuteness. Test Your Knowledge Now, let's test your knowledge on polygons with some real SAT math examples. 1. 2. 3. 4. Answers: D, C, G, G Answer Explanations: 1. In order to find the number of distinct diagonals, we can, as always, either use our diagonal formula or be very (very) careful to draw our own. Let us try both methods. Method 1: formula ${n(n - 3)}/2$ We have a hexagon, so there are 6 sides. We can therefore plug 6 in for n. ${6(6 - 3)}/2$ $6(3)/2$ $18/2$ $9$ There will be 9 distinct diagonals. Our final answer is D, 9. Method 2: drawing it out If we draw our own diagonals, we can see that there are still 9 diagonals total. We can color-code these lines here, but you will not have that option on the test, so make sure you are both able to draw out all your diagonals and not count repeat lines. When done correctly, we will have 9 distinct diagonals in our hexagon. Our final answer is D, 9. 2. We know that, by definition, a parallelogram has two pairs of equal sides. So if one side measures 12, then at least one of the other three sides must also measure 12. So let us first subtract our pair of 12-length sides from our total perimeter of 72. $72 - 12 -12$ 48 The remaining pair of sides will have a sum of 48. We also know that the remaining pair of sides must be equal to one another, so let us divide this sum in half in order to find their individual measures. $48/2$ 24 This means that our parallelogram will have side measures of: 12, 12, 24, 24 Our final answer is C. 3. We are told that each of these rectangles is a square, which means that the side lengths for each square will be equal. We also know that, in order to find the area of a square, we can simply square (multiply a number by itself) one of the sides. So, if the larger square has an area of 50 square centimeters, that means that one of the side lengths squared must be equal to 50. In other words: $s^2 = 50$ $s =√50$ $s =√25 *√2$ $s = 5√2$ (For more info on how to manipulate roots and squares like this, check out our guide to ACT advanced integers.) So now we know that the length of each of the sides of the larger square is $5√2$. We also know that the area of the smaller square is 18 and that the length of one of the sides of the shorter square is the length of the side of the larger square, minus x. img src="http://cdn2.hubspot.net/hubfs/360031/body_square_example.png" alt="body_square_example" style="display: block; margin-left: auto; margin-right: auto; width: 212px;" width="212" So let us find x by using this information. $(5√2 - x)^2 = 18$ $5√2 - x =√18$ $5√2 - x =√9 *√2$ $5√2 - x = 3√2$ $-x = -2√2$ $x = 2√2$ We have successfully found the length of $x$. Our final answer is G,$2√2$. 4. We have a few different ways to solve this problem, but one of the easiest is to use the strategy of plugging in our own numbers. This will help us to visualize the lengths and areas much more solidly. So let us imagine for a minute that the longest length of our rectangle is 12 and the shorter side is 4. (Why those numbers? Why not! When using PIN, we can choose any numbers we want to, so long as they do not contradict our given information. And these numbers do not, which means we're good to go.) Now, to make life even simpler, let us divide our rectangle in half and just work with one half at a time. Now, because we have divided our rectangle exactly in half (and we know that we did this because we are told that F and E are both midpoints of the longest side of our rectangle), we know that BF must be 6. Now we have four triangles, three of which are shaded. In order to find the ratio of unshaded area to shaded area, let us find the areas of each of our triangles. To find the area of a triangle, we know we need: ${1/2}bh$ If we take the triangle on the left, we already know that our base is 4. We also know that the height must be 3. Why? Because point G is directly in the middle of our rectangle, so the height will be exactly half of the line BF. This means that our left-most triangle will have an area of: ${1/2}bh$ ${1/2}(4)(3)$ $(2)(3)$ $6$ Now, we know that our right-most triangle (the unshaded triangle) will ALSO have an area of 6 because its height and base will be exactly the same as our left triangle. So let us find the areas of our top and bottom triangles. Again, we already have a given value for our base (in this case 6) and the height will be exactly half of the line BA. This means that the area of our top triangle (as well as our bottom triangle) will be: ${1/2}bh$ ${1/2}(6)(2)$ $(3)(2)$ $6$ Both the left and the top-most triangles have an area of 6, which means that ALL the triangles have equal areas. There is 1 unshaded triangle and 3 shaded triangles. This means that the ratio of unshaded to shaded triangles is 1:3. We also know that this will be the same ratio if we were to complete the problem for the other half of the rectangle. Why? We cut the shape exactly in half, so the ratio of all the unshaded triangles to shaded triangles will be: 2:6 Or, again: 1:3 Our final answer is G, 1:3. A little practice, a little flare, and you've got the path down to all your right answers. The Take Aways Once you internalize the few basic rules of polygons, you’ll find that these questions are not generally as difficult as they may appear at first blush. You may come across irregular polygons and ones with many sides, but the basic strategies and formulas will always be the same. Remember your strategies, keep your work well organized, and know your key definitions, and you will be able to take on even the most difficult polygon questions the ACT can throw at you.

Bo Burnham by Bo Burnham

Bo Burnham â€Å"I’m the greatest rapper ever,† as said by he himself, Bo Burnham in his hit song â€Å"I’m Bo Yo† from the self-titled album, â€Å"Bo Burnham.† If I were to say so, I’d have to agree with this statement. Bo Burnham, a musician, comedian, actor and singer/songwriter, is most known for the thing he created out of most or all of these traits, a great freestyle rapper. The greatest parts about this whole thing is when I got the album, how I found out he was discovered, and how well he can do his thing. I bought the album â€Å"Bo Burnham† off of iTunes one day because I had just found my favorite song-to-be, â€Å"I’m Bo Yo.† I went through the whole album and could have just laughed my head off. His songs are nicely put together for a freestyle rap album. Every song I listened to was turning into my new favorite song by him. I was kind of expecting this to happen however, as I like freestyle rap because it’s made up as you go. Pretty much every song he writes, or thinks of, is coming from the top of his head, and that’s what I like about it; it’s original! Bo started his career while writing songs and performing them to his fellow classmates. He then decided to tape himself singing them and post the videos on YouTube. He intended to do this so his brother Pete could watch them as he was at college at the time, but never did he expect what was about to happen next. In the fall of 2007, a talent agency called The Gersh Agency, called up Bo and told him that he needed to be represented by them. It was a dream come true. Bo Burnham can rap as well as anyone, people like Eminem and such. Bo may be criticized about the music he creates and plays, but what really matters to him, is that he gets to do what he wants. So if you ever decide, â€Å"hey I wanna do freestyle rap someday†, please give Bo Burnham a good listen. He’s got plenty of good ideas and songs about what to think about. Just give him a listen because you may be surprised about what you hear. If you like comedians, he’s your guy. If you like rap, he might as well be your guy! Just a warning to people, his songs may include profanity, but it’s still worth the listen!

The New Dress Essay Example | Topics and Well Written Essays - 250 words

The New Dress - Essay Example Conformity is a condition of acceptance. A woman’s dress defines her position. Although Mabel is evidently intelligent and well-read, her entire sense of self-worth is centered entirely round her dress. Mabel gives great importance to the men’s opinion. She seeks assurance from Robert Haydon and Charles Burt. She admits that â€Å"If he had only said, â€Å"Mabel, youre looking charming to-night!† it would have changed her life† (6). The men are not defined by their dress. This is clear from the fact that Mabel does not draw attention to their clothes. The men are focused on conversation and are obviously considered superior enough to judge the women’s dresses. Mabel is from a lower social and economic strata than the other women at Mrs. Dalloway’s party. She cannot afford a fashionable new dress because that â€Å"meant thirty guineas at least† (2). She comes from a poor background, â€Å"being one of a family of ten; never having money enough, always skimping and paring† (9). She is married to a law clerk and manages â€Å"tolerably in a smallish house, without proper maids† (10). She is dependent on her husband’s income. Her financial constraints contribute towards her feelings of inferiority and insecurity. She attempts to meet the social conventions by mingling with the other party guests, but is tortured by feelings of alienation. In an age in which women are judged not for their personal worth, but largely by their dress, Mabel Waring remains an outsider at the party, as her dress does not conform to the accepted standards of

Performance management article Essay Example | Topics and Well Written Essays - 500 words

Performance management article - Essay Example Measurement of performance is through the collection, analyzing and dissemination of data to assess the production of an individual, group or organization as a whole. For a company’s success in the field, goals are structured as a means for the company to determine its success. This success rate can be measured through financial capacity, the rate of growth of the company or in terms of the quality of the services rendered. By measuring and creating ways to measure the development of the company, it is possible to measure the success of the company. True to many, the business clichà © ‘what gets measured gets done’ is complemented by the study. For a business that is starting up, profit generation is their main objective. Therefore, the managers in charge structure policies that will aid the workforce to attain the necessary goals setup. Use of bonuses is a commonly used method to incentivize the workforce to working better and efficiently. However, change is dynamic and therefore the company’s goals are subject to alteration. As such, the company must know the correct performance measurements systems that help the organization in achieving its necessary goals (Neely, 1999). In the recent past, the use of financial systems to measure performance was common. This enables the firm to know whether they were making the most on their profits, as this is the main objective of any business. From the data collected, the firm can only get the results in figures but no more deductions can be made. However, as the years have passed companies have sought for more complex systems show An example of its implementation is the choice for a firm to focus more on its customer relation services rather than on sales of the company. This will assist the firm to position itself in the market as an organization that cares about the quality of customer care services. The revised measurement will enable the organization to alter

China and Free Trade :: essays research papers

China and Free Trade In the International Business class, free trade has been the cornerstone for economic prosperity. But sometimes free trade can flood the market with cheaper products, causing financial problems for companies in this country. Often, the U.S. government will set up a tariff to help the American companies. But is this the best solution? This is the topic of the article, Bush’s China-Trade Dilemma by Neil King, Jr. published November 14, 2002 in â€Å"The Wall Street Journal.†   Ã‚  Ã‚  Ã‚  Ã‚  Since China joined the World Trade Organization last year, it has become the third largest supplier of goods and services imported to the United States. Many U.S. companies are complaining that China is selling the items below cost and want Congress to impose duties. They accuse China of breaking the free-trade agreement that it made when it joined the WTO. Trade expert, Gary Hufbauer, says, â€Å"It is just a matter of time before we have a repeat of the Japan trade battles, but this time with China.†   Ã‚  Ã‚  Ã‚  Ã‚  But many in Washington believe that if the U.S. files a grievance against China with the WTO, other countries will follow and the WTO system will become overwhelmed with complaints against China. As one U.S. official stated, â€Å"I’m not sure anyone wants to be the first in line to whack China at the WTO.† Overall, China has a good free trade record and is really making an effort to join in the world economy. But China’s success has hurt some U.S. companies and talk of protectionism has started in the U.S. So what does Bush do? The administration praises free trade, but is seriously considering implementing tariffs for protection on certain items. Is this a contradiction? There is another complication that needs to be addressed. Many of the companies that manufacture in China are really American owned, such as Motorola Inc. How will this affect what does the Bush administration will do? Most of China’s companies are backed by foreign investors. China is eliminating trade barriers, cutting import tariffs, and relaxing restrictions on trading licenses.

Fashion: A Cultural Context

‘Fashion' is multi-faceted- a multiple choice- depending on your budget and attitude you can dress ‘in fashion' and yet be totally individual thanks to the available choice, and the liberal dress codes that exists. Only 40 years ago things were very different- discuss the social and cultural changes that have taken place since the 60's that has allowed this phenomenal change to happen, using quotes from authors and academics to underpin your ideas. Introduction As we approach the year 2003, we find a vastly different fashion industry from that which existed only 40 years ago. Although the fashion sector is known for its apid change, we see an industry today that has been dramatically transformed by such new things as new technology, globalisation, and changing consumer values. Every segment of the industry has been required to change to meet new competitive challenges. As a result, we find a fashion industry that has restructured its self to respond to global competition. The industry is faster, is geographically more wide spread and can focus on understanding and serving the consumer more effectively than ever before. Though transportation and communication advances, the industry has become a orldwide production and distribution network. At the same time, new technologies allow close examination of consumer needs and have reduced the time it takes to respond to those needs. One of the most enduring images of the 1960's is undoubtedly the mini skirt. Not merely a new fashion trend but a true icon of the sixties, the mini skirt epitomised the attitudes of the era. The name synonymous with the fame of the mini skirt is of course Mary Quant. Not only was she responsible for creating the infamous mini, but she also led the way for the radical changes in the fashion industry hat made London such a celebrated centre through out the decade. Like most new fashion trends, the mini skirt was an innovative idea sparked off by a series of unique social and cultural changes. Hemlines had been dramatically shortened at other times before the sixties, also in times of great social change, after and during World War 1and World War 2. This fashion revolution happened at the same time as another big cultural change of the century- pop music. Music has and always will be a major influence on fashion and sub-culture. Another huge cultural change of the decade was ‘the pill'. The younger generation was becoming less inhibited, and more sexually promiscuous because of the invention of the contraceptive pill, and clothes became more overtly sexual and revealing. Along the street of Haight Ashbury, hippies could be seen wandering along, wearing their multi-coloured kaftans or afghan coats over fringed tasseled dresses, flat leather sandals, a headband copied straight from the American Indians or a pair of scruffy flared jeans. What had started off for many as an ethical movement by a few die-hard individuals in America soon became a world ide phenomenon influencing lifestyles and creating the main stream fashion of the late sixties. This was a form of anti-fashion as revolt. It was untidy and spontaneous and radically different from the chirpy neatness of the earlier years of the decade and the futuristic fashions of the previous few years. Boutiques such As ‘I was Lord Kitchener's Valet' or ‘Granny Takes a Trip' in London, both reflected the sartorial anarchy of the times with their bright riotous designs. Hippie women reacted against the dolly bird image of the early sixties that with he arrival of the mini skirt had been designed to free the young woman from sexual stereotyping. With its thigh revealing length it confined her in a look, which aimed directly at the male's libido. Although the late sixties have been criticised for its naive belief that free love and marijuana would solve the worlds problems, there was a lot of creative activity which led to permanent social change. People felt free to break down taboos. The woman's, civil and gay rights movements all started in this decade. Sexual stereotypes were being broken down and ‘free love' was on the agenda. Men and woman began to look alike with unisex jeans and long hair, the older generation felt increasingly alienated from the young. Experimenting with gender was part of the revolution. As woman took up the banner for sexual equality, men began to reject the fifties ideal of muscular machismo. The old mores of what constituted male dress were broken down and men experimented with less obviously masculine looks. Much of the late sixties was, for many spent in a haze of drug induced euphoria. The use of LSD was a powerful influence on ideas and dress. People xperimented with their lifestyles in the belief that they were somehow on the road to a greater awareness and under standing, fuelled by the sensory experience of acid and its ability to distort the senses, creates hallucinations and vivid colours. Fashion has always had it's social conscience and can be the perfect vehicle for powerful political messages, from the iconisation of Che Guevara's portrait to the anti- war slogans of Katherine Hamnett's T-shirts. But the truly unexpected that flies in the face of fashion its self can carry as powerful a signal as the blatantly written message. Anti-fashion by definition is the opposite of fashion, so if it exists, it should be different every time fashion changes. But its rules stay the same because what it all represents is all negative- anarchy, destruction of order and instigation of chaos. By the mid 1970's woman had discovered that that trousers gave them a sexual neutrality that allowed them to compete in the work place. The 1980's career girl was now an executive who had business lunches and held boardroom meetings. She was confident, independent and more liberated than ever. Designers created outfits especially for these woman. Denim jeans were re-designed to fit woman, and the designer's name on a visible label became all-important. This period launched ‘power dressing'. Women's trousers have always reflected social change and women's growing confidence in their place in society. This was especially true during the seventies. Now every woman has a pair of trousers of some kind in her wardrobe, whether part of a suit or a pair of faded denim jeans. This continues to illustrate women's increasing sense of equality and freedom of choice in society, of which women's trousers have been a constant measure. Alongside this licence to choose from a range of styles regardless of the context a more serious fashion aesthetic existed. The androgynous clothes many women choose to wear expressed the growing women's movement and their desire to be taken more seriously they entered the work force on a more equal footing. The seventies represented the twilight of an era of sexual liberation, over indulgence and decadence. The sexual revolution may have been discussed at length in the sixties, but it could be argued that it actually happened and exploded in the seventies, especially in increasingly jaded ways. The chic new sexual conventions of the day denied that a person's sexuality could be neatly classified. During the 1980's, fashion became integral to the newly emerging concept of the lifestyle. The new wealth and prosperity hyped in the media were ever more evident throughout the decade. In this decade there was a deregulation of the stock market and an explosion in property prices. This helped establish the culture of the yuppie. There was enormous wealth around, but it was spent with a corporate mentality, so that even the most exotic trophy wife appeared to be dressing not only for her an, but for boardroom approval. Power dressing- dressing to show your importance and bank balance, dressing for success, was in. Even if you were a supermarket shelf stacker, you would still wear your impressive power suit in Your spare time. In the 1990's Princess Diana of Wales, was a major influence. She had the rare gift of combining aristocrat grace with the stature of a catwalk model. She championed the interests of British fashion at home and abroad and had her own unique international stage. Her style emerged over the years into a more sophisticated and confidently intuitive one. Having Diana wear your outfit was a priceless piece of publicity, but even for those who copied, she was a strong influence and a tonic to the industry. She gave hope to a whole new generation of couturiers and mainstream designers, and a new out look to many girls who could now wear such clothes without having to be debutante. To understand the constant changes in fashion, it is important to understand that fashions are always in harmony with their era. As a famous designer expressed it â€Å"Fashion is a social phenomenon which reflects the same continuing change that rides through any given age. Changes in fashion, he emphasised â€Å"Correspond with the subtle and often hidden networks of forces that operate on society†¦ In this sense, fashion is a symbol†. Different views exist on how fashion changes are started. Sprole & Burns categorised these views into two groups as follows- * Because the fashion industry thrives on change, this idea suggests that different segments of the industry force change on the consumer by dictating new trends. Traditionally, European fashion houses exerted a powerful influence; the trade media such as women's wear daily, shaped the industries choices. Therefore, consumer's choices and retailers dictated what would be worn by what they carried. Although all these forces are important, Sproles noted â€Å"Changing fashion is a far more complex phenomenon that those with the industry- centred views may wish to believe†. In recent years, many consumers have become increasingly resistant to having new fashions forced on them. Often consumers now exert a spirit of independence in their dress by wearing what they feel is right for them, regardless of what the industry promotes. * Others who study fashion change, believe consumers are responsible for hat becomes fashionable. Given an array of products from which to chose certain trends develop because a group of consumers establish that these fashions are right. Four major theories suggest how consumers determine the course of new trends; some trends may begin with the upper socioeconomic consumers. Others may occur within all socioeconomic groups. Sometimes fashions rise from subculture groups such as urban African- Americans, youth, blue collar workers and ethnic minorities such as Native American. Nearly any creative or initiative individual can launch fashion trends if they are consistent ith the social climate and lifestyles of the times (Sproles 1981). Men and women are complex creatures whose actions are seldom governed by reason alone. Change comes about for psychological reasons. People grow bored of what they have, the eye wearies of the same colours, lines, and textures after a time. What is new and different appears refreshing, and what has been on the scene for a while appears dull and unattractive. Changes for such psychological reasons occur also in the fashions for products other than clothing. Auto manufacturers introduce new colours and shapes because potential buyers ire of the same colours an shape. Changes in fashion are also caused by rational reasons, such as environmental factors that create knew needs. A classic example of social change that brought about drastic change in fashions occurred in the early decades of the twentieth century, when women sort, gained and enjoyed new political and economic freedom. Their altered activities and concepts of them selves encouraged them to discard the constricting garments that had been in fashion for centuries and to adopt shorter skirts like those of Mary Quants, relaxed waistlines, bobbed hair nd other fashions more appropriate to their more active lives. Generations later, as women moved into top executive positions in the business world, the tailored suit, soft blouses and attachi bags became the ‘dressing for success' fashion of young career women in the late seventies and eighties. The physical fitness movement in the 1970's and 1980's brought about the need for exercise clothing, and as the interest in jogging, hiking, tennis and aerobics grew, also did the need for new and different fashions appropriate to each of these active sports. Casual Fridays and a shift towards working at home have hanged the way many people dressed for work in the 1990's. Even environmental concerns influenced fashion by avoiding the use of certain dyes and finishes harmful to nature. Conclusion Although fashions change constantly and new ones appear almost every season, a full-scale change over is never completed at any one time. In studying the pattern in change in fashions, scholars have observed that changes in fashion are evolutionary in natu re, rather than revolutionary. It is only in retrospect that fashion changes seem marked or sudden. Actually they come about as a result f a series of gradual shifts from one season to the next. For example, when women's skirts became inching up from the mid calf in the 1960's this gradual shortening was not particularly noticeable at first. It was only when skirts moved thigh high, in the form of minis and micro minis, that people took notice of the approaching extreme. Even today, when the rate of fashion change has execrated sharply, the pace of change is really slower than it appears to the unskilled observer who has failed to notice the early evolutionary movements in a new direction. The evolutionary ature of fashion change is a fundamental principle that is recognised by fashion practitioners, it provides them with a solid, factual foundation for forecasting and identifying in-coming fashions. When planning and developing new styling ideas, they always keep the current fashions and evolving directions in mind. Therefore the expectance of a particular coat or dress fashion during a current season becomes a straw in the wind for experts to search for clues to next seasons trends. The degree of it's acceptance provides needed clues as to what will or will not be welcomed by the consumer in the next season. Knowing that people do not respond well to sudden changes, the fashion experts build gradually, not abruptly, towards new ideas. Even the slowest most gradual of evolutionary changes in fashion, do change eventually. Examples of this can be found in history and recent times. For example when the mini skirts of the 1960's moved up to the micro mini skirts of the1970's, hems began inching downward. Whether it be skirt lengths, suit lapels, silhouettes or general fashion looks, all fashions tend to move steadily towards an extreme, at which point a new direction develops.

Online Shopping As A Whole Has Impacted Consumer Behaviors

Online shopping as a whole has impacted consumer behaviors and with Amazon being one of the biggest retailers it has had a significant impact on its consumers’ behavior. The days of having no option but to visit a physical location to conduct shopping are practically forgotten now. What started out as just an online bookstore in 1994 is now a contender for the number one retailer spot currently held by Walmart. Typically, the limited space available in any physical store selling books or CDs, and the fact that browsing physical catalogues took time, meant that a digital store for books and CDs would overcome the two major challenges with shopping for books and CDs at a physical store. Being a digital retailer allowed Amazon to have†¦show more content†¦What made Amazon stand out from the rest and therefore allow it to survive once the bubble burst was that it was focused on long term market leadership to create shareholder value compared to short-term profitability which was the goal of most other companies. Aforementioned is the idea that Amazon carved out a niche for itself. However, in hindsight, they were simply the first in a very large market that other enterprises had failed to identify and capitalize on. Thanks to the volume of sales that Amazon enjoys, it is able to offer discounts ranging from 10 to 30% off the prices of books, this means that other websites have to do better than this to be able to compete with Amazon pricing. Comparing the prices of books and CDs on Amazon to those on other websites is a tedious process that most people are willing to forgo and stick with just Amazon instead (Lewis, 2005). Anyone willing to go through this would have to be under serious financial constraints and in that case, they become vulnerable to websites that claim to offer original books and CDs that may actually be pirated. Since expanding its catalogue to include more than books, there’s little that one cannot find on Amazon as far as frequent and regular purchases go. Notable exceptions are liquor and tobacco, which cannot be bought on the website. This means that the average Amazon consumer in America today has little reason to consider other online merchants, most of who also don’t sellShow MoreRelatedHow Promotions And Advertisements Have On The Choices Of Brand2253 Words   |  10 Pagesshown as below: 1.
