Show that the four points A(3,2,−5),B(−1,4,−3),C(−3,8,−5) and D(−3,2,1) are coplanar. Find the equation of the plane containing them.
A ray of light passing through the point A(1,2,3) , strikews the plane xy+z=12atB and on reflection passes through point C(3,5,9)˙ Find the coordinate so point B˙
A parallelepiped is formed by planes drawn through the points P(6,8,10)and(3,4,8) parallel to the coordinate planes. Find the length of edges and diagonal of the parallelepiped.
Find the distance of the point (−1,−5,−10) from the point of intersection of the line 3x−2=4y+1=12z−2 and plane x−y+z=5.
