Answer:

32

Explanation:

First bounce = 13 / 14 × 10 = 130 /14

using geometric progression where the common ratio = 13/14, the first bound = 130/14

ar^n-1 < 1

substitute the values into the equation

130 /14 × 13/14^(n-1) < 1

(13/14)^n-1 < 1÷ (130/14)

(13/14)^n-1 < 14 / 130

take log of both side

log (13 /14)^n-1 < log ( 14/130)

n-1 log (13 /14) < log  ( 14/130)

since log (13/14) negative

n-1 > (log( 14/130)) ÷ ( log (13/14)

n - 1 > 30.07

n > 30.07 + 1 > 31.07

The 32 bounce will the first less than 1 foot
