Answer:

$h(t)=-6(t-2)^2+24$

Step-by-step explanation:

Given function:

$h(t)=-6t^2+24t$

where:

h = height (in feet)
t = times (in seconds)

Rewrite in the form $h(t)=a(t-h)^2+k$

The quickest way to do this is to expand $h(t)=a(t-h)^2+k$ and compare coefficients with the original function.

$\begin{aligned}h(t)& =a(t-h)^2+k\\ & = at^2-2aht+ah^2+k\end{aligned}$

Comparing coefficients with $h(t)=-6t^2+24t$

$\begin{aligned}\implies at^2& =-6t^2\\ a &=-6\end{aligned}$

$\begin{aligned}\implies -2aht & =24t\\ -2(-6)ht& =24t\\ 12ht & = 24t\\ 12h & = 24\\ h & = 2\end{aligned}$

$\begin{aligned}\implies ah^2+k & = 0\\(-6)(2)^2+k &=0\\ -24+k & =0\\ k &=24 \end{aligned}$

Therefore, substituting the found values into the equation:

$h(t)=-6(t-2)^2+24$

Answer: Answers are in step by step. please like and give a review.

Step-by-step explanation:

1. An obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees.

2. 5x - 8 = 37 if and only if x = 9.

3. If two angles have the same measure, then they are congruent. If two angles are not congruent, then they do not have the same measure. If two angles do not have the same measure, then they are not congruent.

4. 2x + 5 = 3 , then x = 3

5. With 3 equal sides is a equilateral triangle
