Reread Exercise 85. The cross-sectional area of the gutter
Chapter 11, Problem 11.1.271(choose chapter or problem)
Reread Exercise 85. The cross-sectional area of the gutter is given by the quadratic function f(x) x(20 2x). Graph the function in a [0, 10, 1] by [0, 60, 5] viewing rectangle. Then TRACE along the curve or use the maximum function feature to determine the depth of the gutter that will maximize its cross-sectional area and allow the greatest amount of water to flow. What is the maximum area? Does the situation described in Exercise 85 take full advantage of the sheets of aluminum?
