Question 14 (8 points) if v = -2i+ 4j+ k and w = 4+3 + 3k (a) Calculate v • W. (b) Find the angle between V and W. Round to the nearest hundredth of a degree. Copy the problem down onto your blank paper and show all work in solving the problem. You do not need to enter a response in the D2L quiz.
Given v= 2i and w=21 + 3), find the angle between v and w. The angle between v and w is approximately º (Type your answer in degrees. Do not round until the final answer. Then round to the nearest tenth as needed.)
