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.
0.7
6 is in the tenths place, 8 is in the hundredths place, and 2 is in the thousandths place. Since 8 is greater than 5, you round the 6 up to 7.
{(2,0),(-5,-2),(10,8),(6,0),(-9,-2)} is the correct answer (D)

Yes yes yes yes yes
If you subtract 3-7 and add 9 to it the result is 5. 3-7+9=5
