Question 536602: I will pay you $5.00 for the answer
1. After completing the fencing job from two weeks ago, the company sends you to construct some fencing near a river. Your client wants you to enclose a corral adjacent to a river as in the diagram below.
----------------------------------------------------------
~ ~
~ River ~ ~

-----------------------------------------
x
a. Write an equation that represents the area of the enclosure.
b. If you solved for y, what would be the new equation?
c. If L stands for the length of the fence, in yards, write an equation that represents the length of fencing that you need.
d. If you substituted your equation from part b into your equation in part c, then L will result in a rational function. Express L as a rational function.
2. Which quadrant(s), if graphed, would be appropriate to use for this problem? Justify your conclusion.
Part 2
Fences R Us wants to replace their office’s traditional computers and two-dimensional monitors with a virtual reality system. The fixed monthly cost will be $750,000, and it will cost $400 to produce each system.
1. Write the cost function C, of producing x virtual reality systems.
2. Write the average cost function, A , of producing x virtual reality systems.
3. Find and interpret A(200), A(2,000) and A(20,000).
