Homework Help: Math

Posted by Anonymous on Wednesday, February 27, 2008 at 11:08am.

This question makes reference to an orthonormal basis (i,j), and an origin O.

1. Consider the triangle ABC, with vertices A(0,-2), B(9,1), C(-1,11).
Find:

a) a cartesian equation of the altitude from C;

b) a cartesian equation of the circle which has BC as a diameter;

c) a cartesian equation of the circle with C and the line through A and B as a tangent

d) the points of intersection of the circles described in b) and c)


?*cartesian equation is y=mx+c

Please help. I really don't get this.
