A ball is dropped from a height of 10 feet. After bouncing, it reaches a height that is 80% of the height from which it was dropped. This bouncing trend continues till the ball comes to a rest. Show that the distance the ball falls on each drop follows a geometric sequence.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
