1. Identify each of the following statements as true or false. [6 marks] a) The vectors u and 5u are parallel. b) Two vectors in R3 are always coplanar. c) In R2, if u and v are non-zero colinear vectors, then any vector w can be expressed as a linear combination of u and v' in only one way. d) The set of vectors { (3, - 2) (-3, 2)} spans R2. e) For the points A(-5, 2, 0) and B(9, 2, -14), BA =(14 ,0,-14). f) If 1 = i - 27 + 3k , then |v| = 14
