- Geometry The perimeter of a rectangle is 200meters. (a) Draw a diagram that gives a visual representation of the problem. Let x and y represent the length and width of the rectangle, respectively. (b) Write yas a function of x.Use the result to write the area A as a function of x. (c) Of all possible rectangles with perimeters of 200meters, find the dimensions of the one with the maximum area.arrow_forwardMaximum Area A Norman window is constructed by adjoining a semicircle to the top of an ordinary rectangular window (see figure). The perimeter of the window is 16 feet. (a) Write the area A of the window as a function of x. (b) What dimensions produce a window of maximum area?arrow_forwardFencing a Horse Corral Carol has 2400 ft of fencing to fence in a rectangular horse corral. (a) Find a function that models the area of the corral in terms of the width x of the corral. (b) find the dimensions of the rectangle that maximize the area of the corral.arrow_forward
- Maximum Area A rancher has 200 feet of fencing to enclose two adjacent rectangular corrals (see figure). (a) Write the area A of the corrals as a function of x. (b) What dimensions produce a maximum enclosed area?arrow_forwardProfit A company that produces calculators estimates that the profit P(in dollars) from selling a specific model of calculator is given by P=152x3+7545x2169,625,0x45 where xis the advertising expense (in tens of thousands of dollars).For this model of calculator, an advertising expense of $400,000(x=40)results in a profit of $2,174,375. (a) Use a graphing utility to graph the profit function. (b) Use the graph from part (a) to estimate another amount the company can spend on advertising that results in the same profit. (c) Use synthetic division to confirm the result of part (b) algebraically.arrow_forwardMaximum Revenue A small theater has a seating capacity of 2000.When the ticket price is 20,attendance is 1500.For each 1decrease in price, attendance increases by 100. (a) Write the revenue R of the theater as a function of ticket price x. (b) What ticket price will yield a maximum revenue? What is the maximum revenue?arrow_forward
- Maximum Volume You construct an open box with locking tabs from a square piece of material, 24 inches on a side, by cutting equal sections from the corners and folding along the dashed lines (see figure). (a) Write a function V that represents the volume of the box. (b) Determine the domain of the function V . (c) Sketch a graph of the function and estimate the value of x for which V(x) is a maximum.arrow_forwardMaximizing revenue A seller of contemporary disks finds that he can sell (820x) desks each month when the price is x dollars. What price will maximize revenue?arrow_forwardMaximizing land area Jake has 800 feet of fencing to enclose a rectangular plot of land that borders a river. If Jake doesnt need a fence along the side of the river, find the length and width of the plot that will maximize the area. What is the largest area that can be enclosed?arrow_forward
