(d) The eigenvalues of A are distinct. What are the dimensions of the corresponding eigenspaces? Explain.
O The multiplicity of each eigenvalue is 1, so the dimensions of the corresponding eigenspaces are 1.
The multiplicity of each eigenvalue is 1, so the dimensions of the corresponding eigenspaces are 5.
O The multiplicity of each eigenvalue is 5, so the dimensions of the corresponding eigenspaces are 1.
O The multiplicity of each eigenvalue is 5, so the dimensions of the corresponding eigenspaces are 5.
(e) Is A orthogonal? Explain.
O Yes, because the columns form an orthonormal set.
O No, because the columns do not form an orthonormal set.
(f) For the eigenvalues of A, are the corresponding eigenvectors orthogonal? Explain. (Select all that apply.)
O yes, by the Real Spectral Theorem
yes, by the Property of Symmetric Matrices
yes, by the Fundamental Theorem of Symmetric Matrices
no, by the Real Spectral Theorem
no, by the Property of Symmetric Matrices
