The height of a small rock falling from the top of a 124-ft-tall building with an initial downward velocity of -30 ft/sec is modeled by the equation h(t) = -16% - 30t + 124, where t is the time in seconds. For which interval of time does the rock remain in the air?

O

t = 2

-2
0
t> 2

For the time interval 0 to 2 the ball is in the air.

Select the options according to this.

Step-by-step explanation:

The equation should be

Let's find the x intercepts to answer this question.

To find x intercept where the h(t) is 0.

Solve the equation for t.

Use quadratic formula to solve the equation.

a=-16

b=-30

c=124

Plug in the values of a, b and c into the formula

Simplify it

Simplify it to get two values for x

x can not be negative, here x represents time t.

So, it starts from 0 and remains in the air for 2 seconds.

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
