kap26 [50]

Answer:

8 inches.

Step-by-step explanation:

In the first bounce, the height that the ball reaches was 125 inches.

If the ball always bounces back to $\frac{2}{5}$ of the height, then after 2nd bounce it will reach $(125 \times \frac{2}{5}) = 50$ inches height.

Again, after 3rd bounce, it will reach $(50 \times \frac{2}{5}) = 20$ inches height.

And, after 4th bounce, it will reach $(20 \times \frac{2}{5}) = 8$ inches height. (Answer)

Sindrei [870]

Answer:

a8 = 0.004

Step-by-step explanation:

Q is abt a geometric series given by the eqn: an = a1*r^(n-1)

given a1 = 40000, r = 0.1

an = 40000*(0.1)^(n-1)

a8 = 40000*(0.1)^(8-1)

= 40000*(0.1)^7

= 0.004
