- Finding a Basis for a Row Space and RankIn Exercises 43-46, find a a basis for the row space and b the rank of the matrix. [124361]arrow_forwardFinding the Nullspace of a MatrixIn Exercises 27-40, find the nullspace of the matrix. A=[523121]arrow_forwardTrue or False? In Exercises 73 and 76, determine whether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If a statement is false, provide an example that shows the statement is not true in all cases or cite an appropriate statement from the text. a If an mn matrix B can be obtained from elementary row operations on an mn matrix A, then the column space of B is equal to the column space of A. b The system of linearity equations Ax=b is inconsistent if and only if b is in the column space of A.arrow_forward
- Proof Prove that the main diagonal of a skew-symmetric matrix consists entirely of zeros.arrow_forwardFinding the nullspace of a matrix in exercise 27-40, find the nullspace of the matrix. A=[2113]arrow_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
- Determine Symmetric and Orthogonal Matrices In Exercises 25-32, determine wheter the matrix is symmetric, orthogonal, both, or neither. A=[4503501035045]arrow_forwardProof Prove that if A is row-equivalent to B, then B is row-equivalent to A.arrow_forwardConsistency of Ax=bIn Exercises 57-62, determine whether bis in the column space of A. If it is, write bas a linear combination of the column vectors of A. A=[130110201], b=[123]arrow_forward
- Orthogonally Diagonalizable Matrices In Exercises 37-40, determine whether the matrix is orthogonally diagonalizable. [3112]arrow_forwardProof Prove that if A and B are similar matrices and A is nonsingular, then B is also nonsingular and A1 and B1 are similar matrices.arrow_forwardTrue or False ? In Exercise 73-76, determine whether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If statement is false, provide an example that shows the statement isnt rue in all case or cites an appropriate statement from the text. a The column space of matrix A is equal to the row space of AT. b The row space of a matrix A is equal to the column space of AT.arrow_forward
