During the Boston Marathon, a certain runner averages running 25 miles in 5 hours. What are the unit rates for this situation? (How far can they run in 1 hour and how long does it take to run 1 mile?)

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

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.
