Complete parts a through f below to find nonnegative numbers x and y that satisfy the given requirements. Give the optimum value of P. x
Complete parts a through f below to find nonnegative numbers x and y that satisfy the given requirements. Give the optimum value of P. x + y = 78 and P =x2y is maximized a. Solve x+y=78 for y. y= 78-x b. Substitute the result from part a into the equation P = x2y for the variable that is to be maximized. mm (a) The function to be maximized is V(x) where x is the side length of the square. Find the formula of the function to be maximized. V(x) = D (b) A square with a side of length should be cut away from each corner to obtain the maximum volume. (Round to two decimal places as need inches inches inchesAcandy box is made from a piece of cardboard that measures 27 inches by 15 inches. Squares of equal size will be cut out of each corner. The sides will then be folded up to form a rectangular box. What size square should be cut from each corner to obtain maximum volume? Complete parts (a) and (b). (a) The function to be minimized is A(s), where A is the surface area, and s is the side length of the square bottom. A(s) =(b) The dimensions of the tank with minimum surface area are E El (Simplify your answer.
