Answer:

Step-by-step explanation:
Given:
Center of circle is at (5, -4).
A point on the circle is 
Equation of a circle with center
and radius 'r' is given as:

Here, 
Radius of a circle is equal to the distance of point on the circle from the center of the circle and is given using the distance formula for square of the distance as:
Using distance formula for the points (5, -4) and (-3, 2), we get

Therefore, the equation of the circle is:

Now, rewriting it in the form asked in the question, we get

Answer:
20
Step-by-step explanation:
20 x 10 = 200
10% = 0.10
200 x 0.10 = 20
Answer:
B
Step-by-step explanation:
Answer:
-5/8h + 7
Step-by-step explanation:
First you need to combine like terms (1/8h and -3/4h)
So 1/8h - 3/4h is -5/8h
Then we have our 7 left over
So the answer is -5/8h + 7
