Which is the best type of graph to model the speed of a roller coaster over the full two minutes it takes to complete the ride?

Step-by-step explanation:

I would say a speed/time line graph because those types of graphs are usually used for these scenarios in Physics problems.

Hope this helped!

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.
