1) y = x
2) y = -(1/5)x + 4
3) y = -6x + 2
4) y = x + 2
5) y = (1/2)x + 2
6) y = -x + 4
7) y = -x + 1
8) y = (3/2)x + 2
9) y = -(3/2)x - 2
10) y = 2x - 1
I think after the 9th bounce it will lose 90% of its max height
times 40 by 0.9 which will give you 36
then take 36 away from 40 leaving you with 4.
answer = 4ft
Answer - 5%
6740=100%
337= x
Criss cross so do 100x337 and then divide by 6740 and you’ll get 5 which you can check by doing 5/100 of 6740
