Answer: a) H = h( 0.5 )^n
b) H = 1.125inches
Step-by-step explanation:
Let H = height of the ball
n = number of time the ball bounces
h = initial height.
The exponential function to model the height of the ball will be:
H = h( 1 - 0.5)^n
H = h( 0.5 )^n
It's minus because the height of the ball is decreasing.
h = 36 inches
n = 5
H = 36( 1 - 0.5 ) ^5
H = 36( 0.5 )^5
H = 36 × 0.03125
H = 1.125inches

Answer:
radius i think
Step-by-step explanation:
Commission is $15.00 on the first.
$48 on the second.
Ok
so paid 16
20% off
original-20%=16
that means the shorts were 100-20=80% of the original cost
percent means parts out of 100
80%=80/100=0.80
16=0.8 of ogirinal cost
'of' means mutpliy
16=0.8 times original
divide both sides by 0.8
16/0.8=ogirinal
20==originall
$20=original price
