= r
The 0.7 gives the next height of each bounce
For example say first bounce was 7 ft then next bounce will be t*0.7 = 4.9 ft
Then next boune will be 7*(0.7)^2 and so on.

Answer:
1) s = 12.25
2) n = 3
Step-by-step explanation:
2) 6n - 1 = 4n - 5
<u> -4n -4n </u>
2n -1 = 5
<u> +1 +1</u>
<u>2n</u> = <u>6</u>
2 2
n = 3
