Stephanie accidentally hit a golf ball through her neighbor’s square window with side length x. She needs to buy a new piece of glass to replace the one she broke. Part A Write a variable expression for the area of the glass piece Stephanie needs to replace. Part B If the window is 20 in. wide, what is the area of the glass piece Stephanie needs to replace? Part C If Stephanie has a budget of $100, what is the most she can pay per square inch of glass to replace the window described in Part B? Explain.

To find the extreme values of a function f(x. y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x, y)=xy
