The temperature of a liquid in an experiment changes by −10.4°F from the beginning of the experiment to the first check. After making some adjustments, the scientist checks the temperature again later and finds that it is 17.7°F, which is 1/3 what it was at the time of the first check. What was the initial temperature of the liquid?

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.
