answer in following concerning span and linear combinations a) describe circumstance in which the span vectors {u,v,w} is a plane in R3 b) determine if given vector w is a linear combination of vector v1 = <1,2> and vector v2 = <1,3>. If it is, find a, b such that vector w = aV1 + bV2 (v1,v2 are vectors). Use vector w = <1,-5>

Prove: If V = {V1, V2, ...,V) is a linearly indepen- dent set of vectors in R", and if W = {Wx+1, ...,wn} is a basis for the null space of the matrix A that has the vectors V1, V2, ..., Vk as its successive rows, then VUW = {V1, V2, ..., Vk, Wk+1,...,w.} is a basis for R". [Hint: Since V UW contains n vectors, it suffices to show that VUW is linearly independent. As a first step,...

All vectors and subspaces are in R”. Mark each statement True or False. Justify each answer. Complete parts (a) through (e) below. a. If W is a subspace of R" and if y is in both W and wt, then y must be the zero vector. If v is in W, then projwv = Since the wt component of v is equal to v the w+ component of v must be A similar argument can be formed for the W...
