Ethan and Michael are 64 m apart. If they walk toward each other, they will meet in 8 seconds. If they walk in the same direction, Ethan will catch up with Michael in 32
seconds. Find the walking speed of Ethan and of Michael.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

hi how are you doing today? if you ever need just tell me

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.
