The following matrices are used in Exercises 35-45. $A^{-1} = \begin{bmatrix} 3 & 1 \\ 0 & 2 \end{bmatrix}$, $B = \begin{bmatrix} 1 & 2 \\ 2 & 1 \end{bmatrix}$, $C^{-1} = \begin{bmatrix} -1 & 1 \\ 1 & 2 \end{bmatrix}$. (9) In Exercises 35-45, use Theorem 17 and the matrices in (9) to form $Q^{-1}$, where $Q$ is the given matrix. 35. $Q = AC$ 37. $Q = A^T$ 36. $Q = CA$ 38. $Q = A^T C$
