Answer:

r = 6 in

Step-by-step explanation:

$V = \pi r^{2} \frac{h}{3}$ = $216\pi$

r²h/3 = 216

r² (18/3) = 6 r² = 216

r² = 216/6 = 36

r = 6

<span>x 2 3 4
f(x) 5.5 7 8.5 </span>

The first function is linear. When you subtract 5.5 from 7, you get 1.5 and when you subtract 7 from 8.5 you also get 1.5. That's how we know it's a linear function because there's clearly pattern. HOWEVER, if you had 5.5, 7, and 9 that would not be a linear function. Why? Because when you take away 7 from 9 you get 2. In order for it to be a linear function you have to get the same exact number when you subtract.

<span>x 0 3 6
f(x) 1 8 64</span>

The second function is exponential because when you divide you get the exact same number. 8/1 = 8 and 64/8 = 8. So this is exponential. But if you had 72 instead of 64 it would not be an exponential function because there has to be a pattern.

I hope this makes sense. Btw I had this question on my test too and this is correct.

Evaluate. –1.65 + (–3.4)

elena55 [62]

Hey there!

This seems like a algebraic expression

SO,
Remember: negative and negative = positive
positive and positive = positive
positive and negative = negative
negative and positive = negative

In this problem we will be doing negative and negative so that means our answer will be a negative

Firstly, lets line up our decimals to solve this problem (once when you do that , you can solve it easier)

$-1.65 
\\ +
\\ (-3.4)
$

Answer: $-5.05$

Good luck on your assignment and enjoy your day
