0.7 is the portion of the previous height that the ball bounces to so, the ball starts at 9, and then on the second bounce, it bounces (0.7)*9 feet, and on the third bounce, it bounces to (0.7)*(0.7)*9 feet, and so on...

The ball bounces to 70% of its previous height with each bounce. The height from which the ball was dropped at the nth bounce is 0.7 feet. @Vocaloid so its A
