Answer both questions. Thank you. If f(x, y, z) = 4zy, then the gradient at the point (5, 4, 5) isV f(5, 4, 5) = Jessica and Matthew are running toward the point P along the straight paths that make a fixed angle of 0 (Figure 1).Suppose that Matthew runs with velocity va (m/s) and Jessica with velocity v, (m/s).Let f(x, y) be the distance from Matthew to Jessica when Matthew is æ meters from P and Jessica is y meters from P.PBFIGURE 1Show that f(x, y) = Vx² + y² – 2xy cos 0.• Assume that 0= T/3.
