1. 2. A boat travels on a heading of 335° 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? Find the equation of the following lines in the required form: a. b. C. d. through the points P(1, -3,2) and Q(9,2,0) [vector equation] with direction vector d = (5,3,-4) and z-intercept 7 [symmetric equations] perpendicular to (x, y, z) = (1, -2, 0)+r(1,-1, 1) through P(1, 3, 5) [parametric equations] through T(2,-5) and perpendicular to the line 3x-6y=5 [scalar equation]
