If a ball is dropped from a 32-foot roof and bounces three fifths as high on each successive bounce, find: a. How high will the ball rebound after its third bounce? Round to the nearest tenth. b. Total number of feet that the ball will travel, including all the bounces. Solve the following recurrence relations by using the characteristic equation. a. an 7an-1- 10an-2 b.-an- 10an-1-25an-2 ao = 1, a1 = 4
