Question

Suppose a ball is dropped from a height of 6 ft. It bounces back up but each time it bounces, it reaches only 7/10 of its previous height. What is the total of each height that the ball reaches after 5 bounces?
A. 98.0243 ft
B. 10.6386 ft
C. 39.0806 ft
D.16.6386 ft

Answer 1

6
6 * 0.7 = 4.2
4.2 * 0.7 = 2.94
2.94 * 0.7 = 2.058
2.058 * 0.7 = 1.4406
1.4406 * 0.7 = 1.00842

4.2 + 4.2 + 2.94 + 2.94 + 2.058 + 2.058 + 1.4406 + 1.4406  =
