Answer:

D

Step-by-step explanation:

The surface area is the area of all the surfaces. The surface area of cylinder has the formula:

SA_{cyl}=2\pi r^2 +2\pi rh

Where

r is radius

h is height

r is 8

h is 3

Substituting, and keeping \pi as is, we have:

SA_{cyl}=2\pi r^2 +2\pi rh\\SA_{cyl}=2\pi (8)^2 +2\pi (8)(3)\\SA_{cyl}=128\pi +48\pi\\SA_{cyl}=176\pi

Thus,

Surface Area = 176\pi  units squared, answer choice D is right

The answer is: [B]: x <span>> -10
__________________________
Explanation:
___________
Given the inequality:
___________
</span>→  <span>x + 2 > - 8  ;
____________
</span>→ Subtract<span> "2" from EACH side; to isolate "x" on one side; and solve, or simplify, for "x" ;
_______________________
</span>→  x + 2 − 2 > - 8 − 2 ;  to get:
_______________________
→  x > -10 ; which is: 'Answer choice: [B]'.

Help me in number 3!!!
Alecsey [184]
Answer: G

Explanation/Calculation:

You can clearly see that the white shapes are positive while the black shapes are negative. You can determine this because all (except F) claim that the 6 shapes are negative.

To make it easier, use elimination. It's definitely not J because you are not subtracting -6, but adding (as seen in the equation.) It is not F because 2(3)=6 when the equation needs -6.

So it is either G or H...

H claims that 12x+3+(-6) is what the model symbolizes; but this is incorrect. Unless x is a decimal, you can not have the large shape as the "purest" form (so to speak.) The "purest" state you can go in this model is a cube/square which=1.

Therefore, "G Jamey modeled 12 + 3x + (-6) and it is equivalent to 12x-3" is the correct answer.

Hope this helps you!

Write an recursive formula for An, the nth term of the sequence<br> 5, -2, -9,
oksian1 [2.3K]

Given:

The given sequence is:

5,-2,-9,...

To find:

The recursive formula for a_n, the nth term of the sequence.

Solution:

We have,

5,-2,-9,...

Here, the first term is 5.

-2-5=-7

-9-(-2)=-9+2

-9-(-2)=-7

The common difference is -7.

The recursive formula for the nth term of the sequence is

a_n=a_{n-1}+d

Where, d is the common difference.

Putting d=-7 in the above formula, we get

a_n=a_{n-1}+(-7)

a_n=a_{n-1}-7

Therefore, the recursive formula for the nth term of the sequence is a_n=a_{n-1}-7.
