Standard equation of a circle
(x – h)2 + (y – k)2 = r2
With (h, k) being your center coordinates.
If a circle with a center is on the x-ais, then its k-value is zero.
So plugging in our two coordinates into the standard equation:
\((-3-h)^2+(2)^2=r^2\)
\((-2-h)^2+(3)^2=r^2\)
Can you solve from here?
Don't know how to do limits yet, but for Part 4, I think it means to solve when x = 0.
So when the x-value is 0, on the graphs, there are two possible answers. Either 3 or -2.
Sorry I haven't learned pre-calc, maybe someone mroe educated can help!
Convert 15 hours to seconds
15 * 60 = 900 seconds
What part of 900 seconds is 15 seconds?
I will leave that for you to solve.
If you can't, reply.
Intersection of units:
(Set A + Set B) - union of sets = Intersection
Can you solve it from here?

Guest, why does doing 26 * 3 give 14 positive divisors?
\(\pi{r^2}=A\)
Lets just say that the radius is 1
So the area would be pi.
If the radius is increased 100%, then the new radius is 2.
Susbtituting 2 into the equation, the new area would be 4pi.
\(\frac{4\pi}{\pi}=4\)
Based on this, can you figure out the answer?
