We wish to enclose with a fence a rectangular region of 2,916 square feet next to a wall. Only 3 sides need to be fenced. The fencing for one side perpendicular to the wall (with dimension c) costs $25/ft. The other two sides (one with dimension y and the other with dimension I) cost $11/ft. . What are the dimensions of the rectangle that minimize cost? What is the minimum cost? What is the cost of the fence C (x, y) in terms of rand y? C(I, y)= The dimensions for the minimized cost of the rectangle that minimize cost are y*= Does O (r, y) have a local maximum, local minimum, or neither at the value of r*,y*? O neither maximum O minimum What is the minimum cost? The minimum cost is
