A cloud drifted above an airplane that was flying at 5,300 meters per minute. At a constant velocity, the cloud moved 5,940 meters to the east in 21.6 minutes. What was the cloud's
velocity?

answer: the common difference is -0.10

step-by-step explanation:

300pi

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.
