A ladder 20 feet long is leaning against the wall of a house (see figure). The base of the ladder is pulled away from the wall at a rate of 4 feet per second. Find the rate at which the angle between the ladder and the wall of the house is changing when the base of the ladder is 19 feet from the wall. Round your answer to three decimal places. 4.097 rad/sec 7.604 rad/sec 0.378 rad/sec 0.338 rad/sec 0.641 rad/sec

Rate of Change A 25-foot ladder is leaning against a house (see figure). If the base of the ladder is pulled away from the house at a rate of 2 feet per second, then the top will move down the wall at a rate of r = 2x 625 − x2 ft/sec where x is the distance between the base of the ladder and the house, and r is the rate in feet per second. (a) Find the rate r when x is 7 feet. (b) Find the rate r when x is 15 feet. (c) Find the limit of r as x approaches 25 from the left.
