Consider a ladder sliding down a wall as in the figure. The variable a is the length of the ladder. The variable h is the height of the ladder's top at time t, and x is the distance from the wall to the ladder's bottom. Suppose that the length of the ladder is 8.3 meters and the top is sliding down the wall at a rate of 0.6 m/s. a Calculate dx when h = 2.2. dt (Use decimal notation. Give your answer to three decimal places.) dx | m/s dt h=2.2
