Question

quick and easy question about circles (x+2)^2(y+2)^2 =121/4.......the center would be (-2,-2) or (2,2)

Answer 1

11/2 is radius right?

Answer 2

the center would be -2,-2 because you have to set x+2 and y+2 equal to 0
x+2=0
x=-2
y+2=0
y=-2

Answer 3

the radius should be 11

Answer 4

11/2

Answer 5

but 121/4 squared is 11/2

Answer 6

yep

Answer 7

the standard equation of a circle is given by:\[(x-h)^2+(y-k)^2=r^2\]so your radius is correct.

Answer 8

oh my bad didnt notice the 121/4 so yeah its 11/2

Answer 9

(h, k) is the center of the circle, so in your case it would be at (-2, -2)
