l. 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? 2. Find the equation of the following lines in the required form: a. through the points P(1, 3, 2) and Q(9, 2, 0) [vector equation] b. with direction vector of. = (5, 3, 4) and z -intercept 7 [symmetric equations] 0. perpendicular to (x, y, z) = (1, 2, 0) + r(1, 1, 1) through P0, 3, 5) [parametric equations] (1. through T (2, 5) and perpendicular to the line 3x 6y = 5 [scalar equation]
