Suppose you are climbing a hill whose shape is given by the equation z = 1000 - 0.005x2 - 0.01y2, where x, y and z are measured in meters, and you are standing at point with coordinates (60, 40, 966). The positive x-axis points east and the positive y-axis points north. If you walk due south, will you start to ascend or descend? At what rate? If you walk northwest, will you start to ascend or descend? At what rate? In which direction is the slope largest? What is the rate of ascent in that direction? At what angle above the horizontal does the path in that direction begin?

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola is (0, –12). the y-intercept of the second parabola is (0, –24). what is the positive difference between the a values for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth
