If the x-coordinate of a point `P` on the join of `Q(22,1)a n dR(5,1,-2)i s4,` then find its `z-` coordinate.
Suppose P divides QR in the ratio `lamda:1` Then the coordinates of P are `" "(5lamda+2)/(lamda+1), (lamda+2)/(lamda+1) and (-2lamda+1)/(lamda+1)`. It is given that the x-coordinate of P is 4. Therefore,...
