which has a greater effect on the volume - changing the radius by a given amount or changing the height by the same amount/ why?
Answers
It will have a greater effect to change a variable’s value that has a greater power on it.
Changing h from 1 to 2 doubles the volume.
Changing r from 1 to 4 quadruples the volume, because 1^2 = 1 and 2^2 = 4. The effect of the change on r is amplified by the power.
Answer:
hanging the radius by a given amount has a greater effect on the volume than changing the height by the same amount. This is because the value of the radius is squared in the formula.Step-by-step explanation:

Find an equation of a line that has a slope 7 and passes through the point 3,11
Answers
Now you need to find b. Plug in (3,11) for x and y, x=3 and y=11.
11 = 7*3 + b
Notice the only variable left is b, so you’ll find b this way.
11 = 21 + b and then subtract 21 from both sides:
11 - 21 = b
-10 = b
Plug that back into the equation and you have y = 7x -10

The Metropolitan Company sells its latest product at a unit price of $7. Variable costs are estimated to be 20% of the total revenue, while fixed costs amount to $6,300 per month. How many units
should the company sell per month to break even, assuming that it can sell up to 5,000 units per month at the planned price?
Answers
9514 1404 393
Answer:
1125
Step-by-step explanation:
The "contribution margin" of each product is 80% of its unit price, or $5.60. In order to break even, the total contribution margin must match the fixed costs.
$5.60n = $6300
n = 6300/5.6 = 1125
The company should sell 1125 units per month to break even.
