Using the given center and point at the circumference, the equation of the circles are:
- a)
- b)
- c)
<h3>
What is the equation of a circle?</h3>
- The equation of a circle of radius r and center is given by:
Item a:
- Center C(5,2), hence .
The point at the circumference is A(11,10), hence:
Hence:
Item b:
- Center C(-2,-5), hence .
The point at the circumference is A(3,-17), hence:
Hence:
Item c:
- Center C(5,-1), hence .
The point at the circumference is A(-2,-5), hence:
Hence:

I believe the answer is E
Answer:
D
Step-by-step explanation:
X^2 + 10x + c
Use the number in front of x, (10), to help you.
First, divide 10 by 2:
10/2 = 5
Second, square the answer, (5).
(x+5)(x+5) = 25
Answer: c=+25
