Near a buoy, the depth of a lake at the point with the coordinates (x,y) is z=200+0.02x2-0.0001y3 , where x,y and z are measured in meters. A fisherman in a small boat starts at the point (80,60) and moves toward the buoy, which is located at (0,0). Is the water under the boat getting deeper or shallower? Explain.

Projectile Motion In Exercises 75 and 76, consider the path of an object projected horizontally with a velocity of v feet per second at a height of s feet, where the model for the path is x2=v216ys. In this model (in which air resistance is disregarded), y is the height (in feet) of the projectile and x is the horizontal distance (in feet) the projectile travels. A ball is thrown from the top of a 100-foot tower with a velocity of 28 feet per second. (a) Write an equation for the parabolic path. (b) How far does the ball travel horizontally before it strikes the ground?

You are in charge of erecting a radio telescope on a newly discovered planet. To minimize interfer-ence, you want to place it where the magnetic field of the planet is weakest. The planet is spherical, with a radius of 6 units. Based on a coordinate system whose origin is at the center of the planet, the strength of the magnetic field is given by M(x, y, z) = 6x - y2 + xz + 60. Where should you locate the radio telescope?
