explain what a basis for a vector space is. How does a basis differ from a span of a vector space? What are some characteristics of a basis? Does a vector space have more than one basis? Be sure to do this: A basis B is a subset of the vector space V. The vectors in B are linearly independent and span V.(Most of you got this.) A spanning set S is a subset of V such that all vectors...
Question 5: Multiple Choices Assume that vi,2,ig are vectors in R3. Let S span ,02,s and let A be the matrix whose columns are these vectors. Assume that 1 -1 1 0 0 0-3a +b-2c We can thus conclude that A. {6,6,6) is L1. B. The point (1,1 - 1) is in the span of (o,2,s) C. The nullity of A is 2 D. The rank of A is 3 E.
