- Verifying Subspaces In Exercises 1-6, verify that W is a subspace of V. In each case assume that V has the standard operations. W is the set of all 32 matrices of the form [aba2b00c] V=M3,2arrow_forwardDetermine subspaces of Mn,n In Exercises 2936, determine whether the subsetMn,n is a subspace ofMn,nwith the standard operations. Justify your answer. The set of all nn diagonal matricesarrow_forwardFill in the blanks. To encode a message, create an invertible matrix A and multiply the row matrices by A (on the right) to obtain the row matrices.arrow_forward
- Give an example showing that the union of two subspaces of a vector space V is not necessarily a subspace of V.arrow_forwardVerifying Subspaces In Exercises 1-6, verify that W is a subspace of V. In each case assume that V has the standard operations. W={(x,y,4x5y):xandyarerealnumbers}V=R3arrow_forwardProof Let A be an nn square matrix. Prove that the row vectors of A are linearly dependent if and only if the column vectors of A are linearly dependent.arrow_forward
