there are two circle on the coordinate plane, circle 1: (x-1)^2+(y-1)^2=9, circle 2: (x+1)^2+(y+1)^2=9. can you calculate the nearest point to (0,0) which outside these two circle?

First, we can find the equations of the lines passing through the centers of the two circles and the point (0,0).

For circle 1, the center is (1,1), so the equation of the line passing through (0,0) and (1,1) is y = x.

For circle 2, the center is (-1,-1), so the equation of the line passing through (0,0) and (-1,-1) is y = -x.

The point where these two lines intersect is (0,0), so we can ignore that point.

Next, we can find the intersection points of these lines with the circles.

For circle 1, we substitute y = x into the equation and get (x-1)^2+(x-1)^2=9, which simplifies to 2x^2-2x-8=0. Solving for x, we get x = -1 or x = 2.

For circle 2, we substitute y = -x into the equation and get (x+1)^2+(-x+1)^2=9, which simplifies to 2x^2+2x-4=0. Solving for x, we get x = -1 or x = 2/3.

Therefore, the four possible intersection points are (-1,-1), (2,2), (-1,1), and (2/3,-2/3).

We want the point that is farthest away from the origin, so we can calculate the distance from each point to (0,0) and choose the maximum.

The distances are:

• From (-1,-1): Distance = sqrt(2)
• From (2,2): Distance = 2sqrt(2)
• From (-1,1): Distance = sqrt(2)
• From (2/3,-2/3): Distance = 2sqrt(2)/3

Therefore, the farthest point from the origin is (2,2), which is outside both circles.
