Answer:
21. 
22. 87.92
Step-by-step explanation:
21. The quotient means division is going to happen between -s and 15. And then take the square root of that.

22. The equation for the volume of a cylinder is this:

The question gives you values for r, and h, so just substitute those values into the equation.
Here is the work:

They told us to use 3.14 for pi, so i will substitute pi with 3.14

Answer:
C) 56
Step-by-step explanation:
These angles are supplementary (they add up to 180):
3x + 31 + 2x - 6 = 180
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 31
<FEG:
2x - 6
2(31) - 6
62 - 6

Answer:
A line is defined by two points. What you need is to find coordinates of another point on the line, and then just draw a line between that point and point (5,1)
Step-by-step explanation:
The general eqation of the line is y=ax+b
We know that the slope is one, which makes a=1
We also know that when x=5, then y = 1
Let's plug it in:
1=1*5+b
1=5+b
b= -4
So the line equation is y=x-4
Let's pick x = 1 (you can pick any x, and just solve to find the y coordinate of another point.
So, when x = 1, y = 1 - 4 = -3
Now draw a line through points (5,1) and (1,-3)
<span>We draw a graph of the function f(x) = x².
Next we translate it 1 unit down.
Look at the picture.
