Which is an equation of a circle with center (5, 0) that passes through the point (1, 1)? HELP ME PLEASE!! Answer Choices:


A.) (x - 1)2 + (y - 1)2 = 17
B.) (x + 5)2 + y2 = 17
C.) (x + 5)2 + y2 = 24
D.) (x - 5)2 + y2 = 17

Answers

Answer 1
Answer: a) first we will calculate the distance between center and given point because this is the radius of circle:

d=√((1-5)^2+(1-0)^2)\n \n d=√((-4)^2+1)=√(17)

b) Now we will write the equation of the circle:

\boxed{\boxed{(x-5)^2+y^2=17}}
