Homework Help: Applied Math- Gr.11

Posted by Greg on Thursday, May 1, 2008 at 11:07pm.

A farmer wants to enclose three sides of a rectangular pasture unsing 1000 yards of fencing. The fourth side does not require fencing because it borders a river.

What dimensions (length and width) should the farmer choose in order to enclose the greatest area?

a) Find at least five ordered pairs, comparing pasture length to its area. Remember: only 1000 yards of fencing available.
(Don't i need the maximum to determine this?)

b) Plot your five data points (length and area) on a grid with scales, and join them roughly. You should get the shape of a parabola.

c) Use your graping calculator to find the quadratic function that related to the data.

d) Graph resulting function by hand. State coordinateds of the point of the graps that yields max area. Find max area the farmer can fence in. What are the dimensions?

Can someone help me with this. I am so lost.

All Help is appreciated.
