(a) Find x and x if u = 21+1+k and v=-4+3)+k. (b) Given an area of the parallelogram is defined by PQ X PR, which is perpendicular to the plane of P(1, -1, 0), Q(2, 1, -1), and R (-1, 1, 2). (i) Find PQ x PR; and (ii) Find the area of triangle with vertices P, Q, and R. (c) The work done by a force F in moving an object through a displacement is given by FF. Given F = 41 +51 + 6k, and the object is moved from the point with coordinates (1, 1, 2) to the point (3, 3, 6). Find the displacement vector ; and (i) (ii) the work done by the force F.
