A circle is defined by the equation given below. x2 + y2- x - 2y - 11/4 = 0
What are the coordinates for the center of the circle and the length of the radius?
A (6, -1), 4 units
B. (1, 1), 4 units
C. (, 1), 2 units
d. (, -1), 2 units​

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
