Answer:
(-5, 2) is the center; the radius is 2.
Step-by-step explanation:
Compare the given (x+5)2+(y-2)2=4 to:
(x+5)^2+(y-2)^2=4
(I have used the symbol " ^ " to denote exponentiation.
Now compare this result to:
(x - h)^2 + (y - k)^2 = r^2
From this comparison we see that h = -5, k = +2 and r^2 = 4.
Thus, we conclude that the center of this circle is at (h, k): (-5, 2), and that the radius is 2.
