1. A boat travels on a heading of 3350 at a constant speed of 28 km/h relative to the water. If the current is 18 km/h with a heading of 60, what is the velocity of the ship and its bearing? Skew lines are lines that are not parallel, yet do not intersect, as shown in the diagram below. Show that the lines (x, y, z) = (2,1,0) + s(l, l, l) and x=3+2t; y=3t; z=lt are skew
