Answer:

$area = 144\pi$

Step-by-step explanation:

$volume = \frac{4}{3} \pi {r}^{3} \\ \\ 288\pi = \frac{4}{3} \pi {r}^{3} \\ \\ 3(288\pi) = 4\pi {r}^{3} \\ \\ \frac{3(288\pi)}{4\pi} = {r}^{3} \\ \\ 216 = {r}^{3} \\ \\ r = \sqrt[3]{216} \\ r = 6$

$area = 4\pi {r}^{2} \\ area = 4\pi ({6}^{2}) \\ area = 144\pi$

Assume f(x) = g(x). Which of the following pairsof functions may be used to represent theequation 3^x+^2 = 7x + 6?

Aloiza [94]

Functions and equations

We have that:

$3^{x+2}^{}=7x+6$

Let's name each side of it with f(x) and g(x):

Then, we have that:

$\begin{gathered} f(x)=3^{x+2} \\ \text{and} \\ g\mleft(x\mright)=7x+6 \end{gathered}$

Then, the answer is C

<h2>Answer: C</h2>

I don't understand this problem on my homework can explain to me how to solve it?

user100 [1]

So he worked 30.5 hours, he just didn't write some of the hours down. To find the hours he didn't write down, you subtract 8+ $7\frac14$ + $8\frac12$ from 30.5, which equals $6 \frac14$
