4. Relative to a fixed origin O, the point A has position vector i + 7j – 2k, the point B has position vector 4i + 3j + 3k, and the point C has position vector 2i + 10j + 9k. Given that ABCD is a parallelogram, (a) find the position vector of point D. → → The vector AX has the same direction as AB . Given that ½AX →½ = 10 2 , (b) find the position vector of X.
