Please write out on piece of paper questions 1,2,3 and 4 thank you

1. Determine - X - and - x - for each pair of vectors. a a a. = [3, -2, 9], - = [1, 6, 6] b. -> = [4.3, 5.7, -0.2], -> = [12.3, -4.9, 8.8] 2. Use the cross product to determine the angle between the vectors - [4, 5, 2] and -> = [-2, 6, 1]. Verify using the dot product. 3. Find the volume of each parallelepiped, defined by the vectors , , and -> W a. - = [1, 4, 3], -> = [2, 5, 6], and - w = [1, 2, 7] b. - = [1, 1, 9], - = [0, 0, 4], and => = [-2, 0, 5] 4. Given = = [2, 2, 3], - = [1, 3, 4], and = = [6, 2, 1], evaluate each expression. a. X b. X v u
