Answer:
0.3125
Step-by-step explanation:
If it decreases by 50% each time it hits the ground then all you have to do is divide 10 by 2 (50%) each time it bounces.
10 / 2 = 5 (first bounce)
5 / 2 = 2.5 (second bounce)
2.5 / 2 = 1.25 (third bounce)
Ect. . .
Until on the fifth bounce it is 0.3125m high.
x = 2 because 5 times 2 = 10 and 10 - 2 = 8
Yes
