First, rewrite the equation in standard form.
The center-radius form of the circle equation<span> is in the format:
(x – h)^</span>2<span> + (y – k)^</span>2<span> = r^</span>2
<span>with the center being at the </span>point<span> (h, k) and the radius being "r".
</span>
(x-3)^2 + (y+4)^2 = 81
From here, you can determine the center and radius. The center is at (3,-4) and the radius is 9.

Answer:
x = 31.4
PQ = 58.8
Step-by-step explanation:
Set up a proportion:
SQ/QP = ST/PR
Substitute in the values they give you:



This means that PQ = 2x - 4 = 2(31.4) - 4 = 62.8-4 = 58.8
Answer:
-108
108
Step-by-step explanation:
Since it is withdrawing, we are taking away -$18 every day for 6 days.
(-18)*6 = -108
Since it is deposits, we are adding to the amount in her account, +$18 for 6 days.
18*6 = 108
The difference is that one is taking away and one is adding each day, resulting in negative or positive change.
