Answer:
The height of the 7th bounce of the ball is 0.90 feet.
Step-by-step explanation:
Given that he successive bounce is 70% of the previous bounce's height, the;
the first bounce height = 7.25 feet
the 2nd bounce height = 7.25 x 0.7
= 5.075 feet
the 3rd bounce = 5.075 x 0.7
= 3.5525 feet
the 4th bounce = 3.5525 x 0.7
= 2.48675 feet
the 5th bounce = 2.48675 x 0.7
= 1.740725 feet
the 6th bounce = 1.740725 x 0.7
= 1.2185075 feet
the 7th bounce = 0.85295525 feet
Thus, the height of the 7th bounce of the ball is 0.90 feet.
