I need some help asap with this. If the volume of a rectangular prism is 160 square inches, and I need to scale it down with a f

actor of 1/10, what is the new volume? I'm really confused and if someone could explain the formula or thought process along with the answer, that'd be great. But if not, just knowing the answer would be fine. Thanks! :)

I think you have to divide it by 10 so the new volume would be 16 square inches.

GIVEN:

Scale factor = 1/10

ANSWER:

V1/V2 = 1/10

160/V2 = 1/10

V2 = 1600 sq inches.

The vertex form of the function <br> y=x^2+8x+29
stira [4]

Answer:

y = (x+4)^2 +13

Step-by-step explanation:

y=x^2+8x+29

To complete the square take  the coefficient of the x term

8

Divide by 2

8/2 =4

Then square it

4^2 =16

y=x^2+8x+16+13

 = (x^2+8x+16)  +13

 = (x+4)^2 +13

The difference between number 20 and its opposite is what percentage of 200? (if you do not remember: opposite of 15 is −15; opp
True [87]
20%

This is because 20 and it's opposite -20 is 40. (20 - -20 = 40). Then 40 is 20% of 200.

Find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.
Maslowich

Answer:

16 pi cubic units

Step-by-step explanation:

Given that a region is bounded by

f(x)=√x, y=0, x=1, x=4

And the region is rotated about x axis.

We can find that here radius would be y value and height would be dx

So volume would be as follows:

If f(x) is rotated about x axis volume

= \pi \int\limits^b_a {y^2} \, dx \\=\pi \int\limits^4_1 {x} \, dx\\=\pi *x^2  ^4_1\\= \pi*16-1\\=15\pi

cubic units.

Each one of four pies were cut into 8 pieces for dinner. After dinner there remained 1/2 of a pie, o pie, 3/8 of a pie and 5/$of
Marizza181 [45]

Answer: What you would have left is 12 pieces of pie

Step-by-step explanation: As stated in the question, one pie has been sliced into 8 pieces, and there are three pies in all. That means we had at the beginning 3 x 8 slices of pie which equals 24 pieces.

Also if each pie had been sliced into 8 pieces then each can be represented as 8/8. Therefore eating one slice would leave you with 7/8 (that is 8/8 minus 1/8).

So, each of the three pies now have the following left overs;

1/2, 3/8 and 5/8.

Adding them all together would give,

1/2 + 3/8 + 5/8

Using 8 as the common denominator

4/8 + 3/8 + 5/8

(4 + 3 + 5)/8

12/8.

Therefore, there would be 12 pieces left altogether, which can also be expressed as one pie and 4 pieces.
