If a toy rocket is launched vertically upward from ground level with an initial velocity of 120 feet per second, then its height h after t seconds is given by the equation h(t) = -16t^2 + 120t. How long will it take the rocket to return to the ground? Group of answer choices

Step-by-step explanation:

Given

Required:

Determine the time taken to return to the ground

From the equation given; height (h) is a function of time (t)

When the rocket returns to the ground level, h(t) = 0

Substitute 0 for h(t) in the given equation

becomes

Solve for t in the above equation

Factorize the above expression

Split the expression to 2

Solving the first expression

Divide both sides by -4

Solving the second expression

Add 30 to both sides

Divide both sides by 4

Hence, the values of t are:

and

shows the time before the launching the rocket

while

shows the time after the rocket returns to the floor

it would more likely be bald eagle because its has more in the box so about 75%.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
