1.Let A=(92−102112111−152162172)A = \begin{pmatrix} 92 & -102 & 112 \\ 1 & 1 & 1 \\ -152 & 162 & 172 \end{pmatrix}A=921−152−10211621121172 and B=(122132−142??????)B = \begin{pmatrix} 122 & 132 & -142 \\ ? & ? & ? \\ ? & ? & ? \end{pmatrix}B=122??132??−142??. Then the value of ATBAA^{T} B AATBA is:a.122412241224b.104210421042c.540540540d.539539539Login to continueOnly logged in users canattempt or see the solution.
