If a paper plane is thrown from the top of a 147-foot cliff into the water below, the height of the plane at any given time can
sasho [114]

Answer:

c. 6.5 seconds.

Step-by-step explanation:

We have been given that a a paper plane is thrown from the top of a 147-foot cliff into the water below, the height of the plane at any given time can be determined by the formula h = -3t^2+147, where h is the height of the plane at t seconds.

To find the time, when plane will be at a height of exactly 20.25 feet, we will substitute h=20.25 in our given formula and solve for t as:

20.25= -3t^2+147

-3t^2+147=20.25

-3t^2+147-147=20.25-147

-3t^2=-126.75

\frac{-3t^2}{-3}=\frac{-126.75}{-3}

t^2=42.25

Take square root of both sides:

t=\pm \sqrt{42.25}

t=\pm 6.5

Since time cannot be negative, therefore, the plane will be at a height of exactly 20.25 feet after 6.5 seconds and option 'c' is the correct choice.
