Could someone show me how to work out these please
1. The circle x^2(y+3)^2=25 meets the x axis at p and q, find the coordinates of p and q?
2. The points A(7,4) B(8,-7) and C(-4,3) lie on a circle. Find the equation of the circle?
3. Find the equation of the tangent at the point (3,1) on the circle
Thanks for your help
On a hunch, I found the slopes of the sides of this triangle.2. The points lie on a circle.
Find the equation of the circle.
The center is the midpoint of the hypotenuse
. . Center: .
The radius is the length of (or or ).
The equation is: .
