radar · Answer

This is similar to the last one except the y value for the center is 0.  It is going to be one of the two that is shown on the left.  Now you can just figure it out, remember you are looking for the x value.  Use the equation for a circle whose center is not at 0,0  in this case (x,0)

radar · Answer

Did you get it right?

radar · Answer

(x-h)^2 + (y-k)^ =r^2
(x-h)^2   +(y-0)^2=25
(x-h)^2 + y^2 =5
-h=10
h=-10 x=-10
center (-10,0)
Choice A, you should of got it from what you learned from the previous problem.
