Find u x v. given that u = (-2, -1, -3) and v = (5, 1, 4) Select one: O a. (-1, -7, 3) O b. (1, -7, -3) O C. -23 O d. (-10, -1, -12) Given u = (6, -5, 1) and v = (-8, -9, 5) , find the angle between u and v. (Round your answer to the nearest whole degree and just give your numerical answer without the degree symbol.) Answer: Find the magnitude of AB , given A = (-5, -5, -9) and B = (11, -3, -1) Answer: The cross product of two 3D vectors will always produce a vector that is o the original two vectors. opposite equal in magnitude orthogonal parallel
