Question

A manufacturer is designing a two-wheeled cart that can maneuver through tight spaces. On one test model, the wheel placement (center) and radius is modeled by the equation (x + 1.5)2 + (y + 1)2 = 9. What is the graph that shows the position and radius of the wheels?

Answer 1

A)

Answer 2

B)

Answer 3

C)

Answer 4

What a question. Basically it wants to know which graph represents the circle with the equation you wrote above.

from the equation you can see the center is at (-1.5,-1) and the radius is 3, right?

Answer 5

yeah

Answer 6

Which graph has those characteristics?

Answer 7

B I think

Answer 8

Close but not quite, the graphs are kinda weird since they go by 2 and are so small. but i think A would be the right one

Answer 9

yeah the graphs are really weird but thank you so much (:
