Use a graphing calcula tor to find the inverse of the matrix. Give five decimal places, if necessary.
-$A=\left[\begin{array}{cc}
\sqrt{3} & -4 \
\frac{2}{7} & 0.932
\end{array}\right]$

A)
$\left[\begin{array}{cc}
0.33803 & 1.45078 \
-0.10363 & 0.62821
\end{array}\right]$

B)
$\left[\begin{array}{lr}
1.97703 & -8.48511 \
-0.60608 & 3.67416
\end{array}\right]$.

C)$\left[\begin{array}{lr}
1.97703 & -8.48511 \
-0.60608 & 3.67416
\end{array}\right]$

D)
$\left[\begin{array}{ll}
0 & 1 \
1 & 0
\end{array}\right]$

Quizplus · Accepted Answer

The inverse of a matrix $A$ is calculated using the formula $A^{-1} = \frac{1}{\text{det}(A)} \text{adj}(A)$, where $\text{det}(A)$ is the determinant of $A$ and $\text{adj}(A)$ is the adjugate of $A$. The given matrix has unique values that, when processed through a graphing calculator or an appropriate mathematical software, yield the inverse matrix provided in option A. The other options either do not correspond to the correct calculation of the inverse matrix or represent different matrices altogether.
