What is the height in feet do not round up the answer
s344n2d4d5 [400]

Answer:

72.25 ft

Step-by-step explanation:

The function that models the height of the ball is

h(t) = 68t - 16 {t}^{2}

The maximum height occurs at:

t =  -  \frac{b}{2a}

t =  -  \frac{68}{2 \times  - 16}  =  \frac{68}{32}  = 2.125

We substitute t=2.125 to get:

h(2.125) = 68(2.125)  - 16(2.125) ^{2}

h(2.125) = 72.25

The maximum height is 72.25 feet

2. sliver's gym

3. fitness planet

4. fitness:345 to sliver: 185

Step-by-step explanation:

1. with zero months

fitness planet cost is C = 22(0)+15= 15

sliver's gym cost is C = 15(0)+5= 5

2. sliver's gym because the rate of change is slower than fitness, resulting in you paying less for monthly memberships

3. Fitness planet because the rate of change is higher meaning that you will pay more for the monthly memberships.

4. Fitness planet C = 22(12)+15 = 345

Sliver's gym C = 15(12)+15 = 185
