Answer: 10 units.
Step-by-step explanation:
The equation of the circle in Center-radius form is:

Where the center is (h,k) and "r" is the radius.
The equation of the circle given is:

You can observe that is written in Center-radius form.
Then, you can identify that:

Knowing this, you need to solve for "r" to find the lenght of the radius.
This is:

Therefore, the lenght of the radius is 10 units.
Its B because i divided 38.25 by 3 and it gave me and answer of 12.75 per hour
Hey there!

Graph coming up right below!
Hope this helps!

Part A: $225y+5x=$480
Part B: f(480)=225=5x
Part C: I'm not sure how to do this but I hope that A and B helps!
What the equation is looking for is the values X needs to have to equal zero
X - 6 = 0
X - 6 (+6)= 0 (+6)
X = 6
X + 2 = 0
X + 2 (-2)= 0(-2)
X = -2
i don't understand what the question is asking for the topmost box though
