hoa [83]
The main assumption here is that the height at the water level is 0.

So, the answer is given by the solution to the equation

- 16t^2 + 16t + 480 = 0

To solve it, start dividing by -16 to get:

t^2 - t - 30 = 0.

Now factor the left side:

(t -  ) (t +  ) =0

Find two numbers that add - 1 and its product is -30

(t -  6 ) (t + 5 ) =0

That gives:

t - 6 = 0 ⇒ t = 6 seconds

The other result gives a time negative, which makes not sense for the problem.

Verify substituing 6 in the original equation:

h(6) = -16*6^2 + 16*6 + 480 = -576 + 96 + 480 = 0. Lo cual confirma nuestra solucion.
 
It toke Rose 6 seconds to hit the water.

Kaylis [27]

Answer:

20

Step-by-step explanation:

Because 21.50 x 20 =430

and 18 x 20 = 360

then you add 70 to 360 and you get 430

so Katrina would have to order 20 shirts from each company in order for the cost to be the same.
