Answers: 3
with the really important part being the x- and the y-. If our first set of parenthesis is
, by the definition of the standard form of a circle, it actually is
which is obviously negative (that's the h of the center of the circle);
, by the definition of the standard form of a circle, it actually is
which is obviously negative (that's the k of the center of the circle). The radius is the square root of the constant on the right, 64. The square root of 64 is 8, soAnother question on Mathematics
