Answer:
As per the statement:
A ball is dropped from a certain height.
The function is given as:
where,
f(n) represents the height in feet
n represents the number of times the ball bounces.
for n = 0
f(0) = 9
Initial height = 9
for n = 1
For n = 2
and so on...
Since;
⇒
In general:
or
therefore, 0.7 represents the ball bounces to 70% of its previous height with each bounce.
x = 52
Step-by-step explanation:
180 - 128 = 52
(I maybe wrong since its been a long time I have done one of these questions, so sorry in advance)
