The average speed of the rocket from 3 to 4 seconds after launch is: -40 ft/s
Given the equation as a model, h(t) =–16t² + 72t.
Average speed from 3 to 4 seconds =
<em>Find h(4):</em>
h(t) =–16t² + 72t
- Substitute 4 for t in the equation h(t) =–16t² + 72t
h(4) = -16(4)² + 72(4)
h(4) = -256 + 288
h(4) = 32
<em>Find h(3):</em>
h(t) = -16t² + 72t
- Substitute 3 for t in the equation h(t) =–16t² + 72t
h(3) = -16(3)² + 72(3)
h(3) = -144 + 216
h(3) = 72
Plug in the value into :
average speed from 3 to 4 secs =
Therefore, the average speed of the rocket from 3 to 4 seconds after launch is: -40 ft/s

3n+2n=2-17
5n = -15
5n÷5= -15÷5
n= -3
The formula is:
Total time = (hose1 * hose2) / (hose1 + hose2)
Total time = (5 * 4) / 5 + 4
Total time = 20 / 9
Total time = 2 + (2/9)
Total time = 2.22222...
