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

Rewrite y= 16x-32 -3 to make it easy to graph using a translation describe the graph
koban [17]

We can rewrite the given expression to:

4*\sqrt{x - 2}  - 3

So the correct option is the third one.

<h3>How to rewrite the expression?</h3>

Here we have the expression:

\sqrt{16x - 32} - 3

Taking the 16 as a common factor inside the square root:

\sqrt{16*(x - 2)} - 3

and 16 = 4², then:

\sqrt{16*(x - 2)} - 3 = \sqrt{4^2*(x - 2)} - 3\\\\4* \sqrt{(x - 2)} - 3

Now, if the parent function is:

y = 4*\sqrt{x}

Our function is the parent function translated 2 units to the right and 3 units down. The correct option is the third one
