2. If a toy rocket is launched vertically upward from ground level with an initial velocity of 128 feet
per second, then its height h after t seconds is given by the equations h(t) = -16° +128t (if air
resistance is neglected).
a. How long will it take for the rocket to return to the ground?
b. After how many seconds will the rocket be 112 feet above the ground?
C. How long will it take the rocket to hit its maximum height?
d. What is the maximum height?

step-by-step explanation:

what "following statement"?

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

what level of math? also i don't need to be paid if i can you.
