True/False Questions If true. give an explanation. If false, give a counterexample. (a) Different matrices cannot have the same RREF. True or fa1se? (b) If the rank of an m x n matrix is n. chen the system Ai = b has exactly one solution. True or fa1se? (c) If A is an n x n matrix and b is a vector in Rn such that Ai = b is inconsistent. then so is Ai = C for any ocher nonzero vector C in !Rn. True or fa1se?

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
