The point (2,n) lies on the circle whose equation is (x-4)^2+(y-2)^2=40. Find the values of n.
The values of n are ___ or _

Step-by-step explanation:

If the point (2,n) lies on the circle whose equation is:

Then this point must satisfy the equation of the circle:

We substitute x=2 and y=n into the equation to get:

We simplify:

This implies that,

Take square root;

Evaluate:

(-1,-0.5)
