Solve the following questions: Q1) find the inverse (if exists) for the following matrix: 2 −1 0 𝐴 = (−1 2 −1) 0 −1 2 1 9 2 3 Q2) If 𝐴 = ( ) and 𝐵 = ( ), what value(s) of 𝑘 that will −1 1 −3 𝑘 make 𝐴𝐵 = 𝐵𝐴? Q3) Determine whether each vector can be written as a linear combination of the vectors in 𝑆 = {(2, −1,3), (5,0,4)} a) 𝑢 = (1,1, −1) 𝑏 = (32, −1,27) Q4) Determine whether the set 𝑆 is linearly independent or linearly dependent a) 𝑆 = {(2, 1, −2), (−2, −1, 2), (4, 2, −4)} b) 𝑆 = {2, 2, 𝑥 + 3, 3𝑥 2 } Q5) Determine whether the following matrices from 𝑀2,2 form a linearly independent set 1 −1 4 3 1 −8 𝐴=[ ],𝐵 = [ ],𝐶 = [ ] 4 5 −2 3 22 23 Q6) Determine whether V is a vector space. If it is, verify each vector space axioms; if not, state all vector space axioms that fail: A) The set of all pairs of real numbers of the form (𝑥, 0) with the standard operations. B) The set of all pairs of real numbers of the form (𝑥, 𝑦), where 𝑥 ≥ 0 , with the standard operations.
