KiRa [710]

Let us cross multiply.

5/9=10/x

9 x 10= 5x

90=5x

90 <u />÷ 5= 5x <span>÷ 5

18=x

So, the answer is 18. I hope this helped you, since I just learned cross multiplication last week.</span>

A model rocket is launched with an initial velocity of 250 ft per second. The height h, in feet, of the rocket t seconds after t

Answer:

{2.96, 12.66}

Step-by-step explanation:

A graph shows the rocket will be 600 feet up after 2.96 seconds, and again at 12.66 seconds.

You can solve the equation h = 600 to find the times.

-16t^2 +250t = 600

-16(t^2 -15.625t) = 600

-16(t^2 -15.625t +7.8125²) = 600 -16(7.8125²)

-16(t -7.8125)² = -376.5625

t -7.8125 = √(376.5625/16) ≈ ±4.8513

t = 7.8125 ± 4.8513 ≈ {2.9612, 12.6638}

The rocket will be 600 ft above the ground 2.96 and 12.66 seconds after launch.
