Q 6Discuss whether the following statements are True or False. Justify your answer.a) A projection matrix P has a single nonzero eigenvalue which is 1.b) For a complex matrix A, determinant of A and A" is always the same.c) If A is Hermitian and Unitary then A2 = Id) Let A be an m x m real matrix. If A is skew-symmetric and m is odd, then A isnonsingular.e) The dimension of the vector space of 4 x 4 real symmetric matrices is 10.e) The hyperplane r+ 2y + 3z = 5 is a vector subspace of Rf) If the columns of A are linearly independent then AAT is always nonsingular.

Since you have posted a question with multiple sub-parts, we will solve the first three subparts for…
