This is a bonus question and I don't really understand it. If you could help in any way, that would be greatly appreciated!
A rancher plans to fence a rectangular pasture adjacent to a river. The rancher has 100 meters of fence, and no fencing is needed along the river.
(a) Express the area A of the pasture as a function of x, the length of the side parallel to the river. What is the domain of A?
(b) Graph the area function A(x) and estimate the dimensions that yield the maxium amount of area for the pastures.
(c) Find the dimensions that yield the maximum amout of area for the pastures by completing the square.
I figured out number a. how exactly are you supposed to find the dimensions if you complete the square? help! please and thank you!
p.s. I figured out b. if i'm right :lol:
