To fill: The blank in the statement “The graph of the equation (x1)2+(y2)2=9 is a circle with center (   ,   ) and radius         .”

Expert Solution

Answer to Problem 6E

The complete statement is “The graph of the equation (x1)2+(y2)2=9 is a circle with center (1,2) and radius 3units.”

Explanation of Solution

Given information:

The statement “The graph of the equation (x1)2+(y2)2=9 is a circle with center (   ,   ) and radius         .”

Consider the provided statement “The graph of the equation (x1)2+(y2)2=9 is a circle with center (   ,   ) and radius         .”

Rewrite the equation as (x1)2+(y2)2=32

The standard form of the equation of the circle is (xh)2+(yk)2=r2 , where (h,k) denote the center of the circle and r denote the radius.

Compare, (xh)2+(yk)2=r2 and (x1)2+(y2)2=32 .

Here, h=1,k=2 and r=3 .

Therefore, center of circle is (1,2) and radius is 3 .

Thus, the complete statement is “The graph of the equation (x1)2+(y2)2=9 is a circle with center (1,2) and radius 3units.”
