Given:

Given that the graph of the circle with center at the point (-3,1)

The standard form for the equation of the circle is given by

where (h,k) is the center.

We need to determine the equation of the circle.

Center and Radius:

Let us substitute the center point (-3,1) in the equation of the circle.

Thus, we get;

--------(1)

Now, we shall find the radius of the circle.

The radius of the circle is the distance from the center to any point on the circle.

The radius can be determined by finding the number of units between the center and the point on the circle.

Thus, there are 2 units between the point and the center.

Hence, Radius = 2 units.

Substituting r = 2 in equation (1), we get;

Thus, the equation of the circle

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it
