Please help me on this. I'm lost with the invertible matrix theorem. This learning module introduced the invertible matrix theorem. This theorem is a collection of 12 equivalent statements. This means that when one statement in the theorem is true, all statements in the theorem are true. Similarly, when one statement in the theorem is false, all statements are false. For your initial post, propose a specific n x n matrix A, where n >= 3. Select four statements from...
Problem 4. Let A, B e Rmxn. We say that A is equivalent to B if there exist an invertible m x m n x n matrix Q such that PAQ = B. matrix P and an invertible (a) Prove that the relation "A is equivalent to B" is reflexive, symmetric, and transitive; i.e., prove that: (i) for all A E Rmx", A is equivalent to A; (ii) for all A, B e Rmxn, if A is equivalent to B...
Review 4: question 1 Let A be an n x n matrix. Which of the below is not true? A. A scalar 2 is an eigenvalue of A if and only if (A - 11) is not invertible. B. A non-zero vector x is an eigenvector corresponding to an eigenvalue if and only if x is a solution of the matrix equation (A-11)x= 0. C. To find all eigenvalues of A, we solve the characteristic equation det(A-2) = 0. D)....

5. This problem is to help you relate many of the topics we have discussed this semester. Fill in the blanks Let A be an n × n matrix. A is nonsingular if and only if (a) The homogeneous linear system A0 has b) A is row equivalent to (c) The rank of A is (d) Theof A are linearly independent (e) Theof A span (f) The (g) N(A) = of R" Of A form a (i) The map V...
Prove the following lemma. Let B be an n ✕ n matrix and let E be an n ✕ n elementary matrix. Then det(EB) = det(E) det(B) 1. Write the proof and submit as a free response. (Submit a file with a maximum size of 1 MB.) 2. Which of the following could begin a direct proof of the statement? If E interchanges two rows, then det(E) = 1 by Theorem 4.4. Also, EB is the same as B but...
12. Which of the following is NOT equivalent to the n xn matrix A being invertible? A. The homogeneous system associated to A has a unique solution. B. Some non-homogeneous system whose coefficient matrix is A has a unique solution. C. Every non-homogeneous system whose coefficient matrix is A is consistent. D. The column space of A is R". E. The linear transformation xH Ax is one-to-one.
Let A = CD where C, D are n xn matrices, and is invertible. Prove that DC is similar to A. Hint: Use Theorem 6.13, and understand that you can choose P and P-inverse.
