The separation of the points A and B is 21-6 = 15. C is located 2/5 of the way from A to B, and 3/5 of the AB distance remains from B to C. That pus C 6 units beyond point A, at a coordinate value of 6 + 6 = 12.

Sorry, it's 180(n-2), because each triangle adds up to 180 degrees, minus the central angles at a point.

In this case we don't know anything about the vertex, so we have to use the more general equation of the form x = ay^2 + by + c using (3/2 , 1) --- 3/2 = a + b + c using (5,0 ) ------ 5 = 0+0+c or c=5 using (-1,2) ----- -1 = 4a + 2b + c from the 2nd we know c=5 so in the first...

the general formula for a parabola with known vertex and horizontal axis is x = a(y-k)^2 + h, where (h,k) is the vertex in your case the vertex , being on the y-axis , can be called (0,k) , and the equation would be x = a(y - k)^2 + 0 for the point (2,4) 2 = a(4-k)^2 (#1) for ...

Yes. You can prove it as follows: From any point inside of the polygon that can connect directly to all the vertices (i.e. without crossing any side of the polygon), connect to all the vertices to form n triangles. The sum of the interior of the n triangles is n*180. From this...
