Suppose you are climbing a hill whose shape is given by the equation below, where x, y, and z are measured in meters, and you are standing at a point with coordinates (140, 240, 526). The positive x-axis points east and the positive y-axis points north. : = 1200 – 0.005x2 – 0.01y? (a) If you walk due south, will you start to ascend or descend? O ascend O descend At what rate? (b) If you walk northwest, will you start to ascend or descend? O ascend O descend At what rate? (Round the answer to two decimal places.)
