A. A student who studied for 0 minutes would expect a score of about 48 on the test.

B. A student who studied 0 minutes would expect a score of about 44 on the test.

C. A student who studied for 48 minutes would expect a score of about 58 on the test.

D. A student who studied for 44 minutes would expect a score of about 52 on the test.

the answer is a

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
