Sand is flowing out of a hopper at a constant rate of 2/3 O 0.04 feet per minute cubic feet per minute into a conical pile whose height is always twice its radius. What is the rate of change of the O 0.007 feet per minute radius of the cone when the cone is 4 feet high? O 0.018 feet per minute O 0.027 feet per minute Consider this graph of P' (1). O At which i-value is P(1) the greatest? O O O 18) Consider the function y = |vil. No, because the function is not differentiable at the Is (0, 0) a minimum point? point (0, 0). Why or why not? No, because the function is not defined at the point (0, Yes, since the function is defined at the point, decreases to the left, and increases to the right. Yes, since the function is defined at the point, increases to the left, and decreases to the right. A 24 inch wire is cut in two and shaped O Asum = 19.689in2 into a square and a regular octagon.
