Fill in the blanks: Coordinate planes divide the space into__________octants.

Planes are drawn through the points (5, 0, 2) and (3, - 2, 5) parallel to the co-ordinates planes. Find the lengths of the edges of the rectangular parallelopiped so formed.

Calculate the co-ordinates of points which divide the join of (3, 4) and (15, 20) into four equal parts.

Planes are drawn parallel to co-ordinate planes through the points (3, 0, -1) and (-2, 5, 4). Find the lengths of the edges of the parallelopiped so formed.

True/False: A circle divides the plane into three parts.

A variable plane which remains at a constant distance p from the origin cuts the co-ordinate axes at A, B, C. Through A,B,C planes are drawn parallel to the co-ordinate planes. Show that locus of the point of intersection is : x^(-2)+y^(-2)+z^(-2)=p^-2
