Find the dot product v middot w and the angle between v and w. v= -4i + 2j + k,w=i + 4j + 4k v middot w = (Simplify your answer. Type an exact value, using radicals as needed.) The angle between v and w is theta = degree. (Do not round until the final answer. Then round to the nearest tenth as needed.)
