Answer:

The center is at ( (-1, -2) and the radius is 5.

Step-by-step explanation:

X^2 + 2X + Y^2 + 4Y = 20

Complete the square on the x and y terms.

(x + 1)^2 -1 + (y + 2)^2 - 4 = 20

(x + 1)^2 + ( y + 2)^2 = 25  Comparing this with the standard form:

(x - h)^2 + (y - k)^2 = r^2

- the center is at ( (-1, -2) and thr radius is 5.

If each car has the same mass which car will require the longest time to come to a full stop
rosijanka [135]

Answer:

Car D

Step-by-step explanation:

Since the mass is the same, we need to depend on the speed. The lower the speed, the easier/faster to stop. The higher the speed, the longer it will take to come to a stop
