Find the scale factor of the two cylinders:

Figure A has an r of 4 and figure B has an r of 2:

2 / 4 = 0.50, so Figure B is half the size of Figure A.


Since you want the volume, which is measured in cubic units, you need to cube the scale factor:

0.5^3 = 0.125

Multiply the volume of Figure A by the scale factor:

352 x 0.125 = 44 cubic feet.

Without drawing the graph of the equation, determine how many points the given equation have in common with the x-axis and where
Gala2k [10]
Remark
It's asking you to complete the square to find the vertex. 

Solve
y = -2x^2 + x + 3 Put brackets around the first 2 terms.
y = (-2x^2 + x) + 3    Pull out the 2.
y = -2(x^2 - 1/2 x) + 3 Be especially observant of the sign on 1/2x Divide the middle term's number by 2 and square it. 
y = -2(x^2 - 1/2 x + [(1/2) / 2]^2 ) + 3 [1/2 divided by 2 is 1/4. (1/4)^2 = 1/16; 2*(1/16) = 1/8
y = - 2(x^2 - 1/2 x + (1/4)^2 ) + 3 + 1/8
y = -2(x - 1/4)^2 + 3 1/8

Comment
Answer to your question. The maximum value (3 1/8) is above the y axis. That means the graph of the equation crosses the x axis twice. I'm going to include the graph because in answering the question, there is no harm in seeing the graph.

1/5 divided 3=1/15 because
Keith_Richards [23]
A number being divided by a number would be the same as a number multiplied by the reciprocal of the other number.

Reciprocal: the “flip” of a fraction (ex. the reciprocal of 6/7 is 7/6)

Example:
5/6 / 1/6
= 5/6*6/1
=30/6
=5

We can apply the same to the question 1/5 / 3.

1/5 / 3
=1/5*1/3
=1/15

I hope this helps! Please comment if you have any questions.
