Question

a circle is tangent to the y-axis at y=3 and has one x-intercept ast x=1(a) determine the other x-intercept

Answer 1

hmm....
one way i can see you do this is solve for the center, (x, y) by using the distance formula:

\(\large \sqrt{(x-0)^2+(y-3)^2}=\sqrt{(x-1)^2+(y-0)^2} \)
solve this equation for x and y ...
then, since the radius is the x coordinate of the center, you can write down the equation for the circle and therefore find the other x-intercept.

Answer 2

yep... this is a multi-step problem....

Answer 3

so i can use any one distance formula which u have given right
