Find the vector v with length 2 and the same direction asthe vector u =(=6,5,3). a) 12 10 b) 12 10 c) 10 70 d) O A OD

Let u and v be vectors. If their dot product is zero what is the angle between u and v (in degrees)?

Which of these vectors is perpendicular to (1, 2, 3) ?MARK ALL THAT APPLY PLEASE. A) (–1, –1, 1) B) (0, 3, –2) - C) (1, 1, 2) D) (3, 3, –10) -
