<u>Given</u>:
The equation of the circle is 
We need to determine the center and radius of the circle.
<u>Center</u>:
The general form of the equation of the circle is 
where (h,k) is the center of the circle and r is the radius.
Let us compare the general form of the equation of the circle with the given equation to determine the center.
The given equation can be written as,
Comparing the two equations, we get;
(h,k) = (0,-4)
Therefore, the center of the circle is (0,-4)
<u>Radius:</u>
Let us compare the general form of the equation of the circle with the given equation to determine the radius.
Hence, the given equation can be written as,
Comparing the two equation, we get;
Thus, the radius of the circle is 8
Answer:
Option C: X=1
Step-by-step explanation:
2(X + 8) - 4x = 10x + 4
2X + 16- 4X= 10X + 4
-2X +16 =10X + 4
16 - 4 = 10X+2X
12 =12X
X=1
Answer:
3r3
Step-by-step explanation:
7 times 3 is as high as you can go w/o over multiplying, and you have a remainder of 3 until you can actually get 24
Answer:
He spent 34 dollars on each book
Step-by-step explanation:
first you subtract 16 from 322 and it would be 306 and then you divide 306 by 9 and that would be the total of each book!! <3
Let O(5, -5) be the center of the circle, and P(6, -2) be a point on this circle.
The distance between points O and P, that is |OP|, is the radius of this circle,
We use the distance between 2 points formula:
|OP|=
(units)
Answer:
units
