# The function f (t) =-16t^2 = 576 represents the height of a freely falling ballast bag that starts from

###### Question:

## Answers

The ballast bag hits the ground after 6 seconds.

Step-by-step explanation:

Suppose there was a small typing mistake.

The height of the ball, after t seconds, is given by the following equation:

[tex]f(t) = -16t^{2} + 576[/tex]

After how many seconds t does the ballast bag hit the ground.

This is t for which f(t) = 0. So

[tex]f(t) = -16t^{2} + 576[/tex]

[tex]-16t^{2} + 576 = 0[/tex]

[tex]16t^{2} = 576[/tex]

[tex]t^{2} = \frac{576}{16}[/tex]

[tex]t^{2} = 36[/tex]

[tex]t = \pm \sqrt{36}[/tex]

Time is a positive measure, so

[tex]t = 6[/tex]

The ballast bag hits the ground after 6 seconds.

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
