A park is represented on a map with the following vertices coordinates: Vertex 1 is at (−4, −1).

Vertex 2 is at (−4, 5) .

Vertex 3 is at (2, 5).

Vertex 4 is at (2, −1).

Lindsey jogs along the the edge of the park in order from vertex 1 to vertex 2 to vertex 3 to vertex 4 and then back to vertex 1. One unit on the coordinate grid equals 20 yards.

What is the total distance Lindsey jogged?

Enter your answer in the box.

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.
