Section 10.3: Problem 7 (1 point) Find the scalar and vector projection of the vector b = (2, 4, 4) onto the vector a = (5, 1, 3). Scalar projection (i.e., component): C] Vector projection (D,D,D) A rectangular box has length 17 inches, width 2 inches, and a height of 20 inches. Find the angle between the diagonal of the box and the diagonal of its base. The angle should be measured in radians. Angle = D Gandalf the Grey started in the Forest of Mirkwood at a point P with coordinates (3, 2) and arrived in the Iron Hills at the point Q with coordinates (4, 6). If he began walking in the direction of the vector v 2 4i + 1j and changes direction only once, when he turns at a right angle, what are the coordinates of the point where he makes the turn? DD
