Question 1: Let vectors: A? =(2,1,−4), B? =(−3,0,1), and C? =(−1,−1,2). Calculate the following: (A) What is the value of  A? ⋅ B? ? (B) What is the angle θAB between A? and B? ? (C) What is the value of 2B? ⋅ 3C? ? (D) What is the value of 2(B? ⋅ 3C?) ? Which of the following can be computed? (Choose only 1 of the following) A? ⋅B? ⋅C?   A? ⋅(B? ⋅C? ) A? ⋅(B? +C? ) 3⋅A? FOR PARTS F THROUGH H: V? 1 and V? 2 are different vectors with lengths V1 and V2 respectively. Find the following: (F) Express Answer in terms of V? 1,   V? 1⋅V? 1 = (G) If V? 1 and V? 2 are perpendicular, V? 1⋅V? 2 = (H) Express your answer in terms of V1 and V2.  If V? 1 and V? 2 are parallel,   V? 1⋅V? 2 =
