The height of a cone is twice the radius of its base.

A cone has a height of 2 x and a radius of x.

What expression represents the volume of the cone, in cubic units?

Two-thirdsπx3
Four-thirdsπx2
2πx3
4πx3

idk what the answer is but for the points

step-by-step explanation:

the first one and the second one that's the answer

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

the square root of what number? if you add that, then someone will probably answer the question.

she would want to sell 10 full-year subscriptions and at least 9 half-year subscriptions to get a total of at least $300. 

i hope this answer you! if you have any further questions or concerns, feel free to ask! : )
