Acircle in the xy-plane is centered at (3, 0) and has a radius with endpoint (1, 8 3 ). which answer choice is an equation of the circle?

Step-by-step explanation:

The vertex form of the equation of a circle is where (h,k) is the center of the circle and r is the radius. This circle has center (3,0). Find the radius using the distance formula with (3,0) and (1,8).

Substitute h = 3, k = 0 and r = √68 into the vertex form. Then simplify for the equation.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

i think the answer is b
