Chapter 11: Q. 70 (page 756)

use a graphing utility to find the inverse, if it exists, of each matrix. Round answers to two decimal places.
$[\begin{matrix} 16 & 22 & - 3 & 5 \\ 21 & - 17 & 4 & 8 \\ 2 & 8 & 27 & 30 \\ 5 & 15 & - 3 & - 10 \end{matrix}]$

Short Answer

Expert verified

The inverse matrix is $[\begin{matrix} 0.01 & 0.03 & - 0.00 & 0.03 \\ 0.02 & - 0.02 & 0.01 & 0.01 \\ - 0.04 & 0.01 & 0.04 & 0.06 \\ 0.05 & - 0.02 & - 0.00 & - 0.09 \end{matrix}]$

Step by step solution

Step 1.Given information

Given matrix is $[\begin{matrix} 16 & 22 & - 3 & 5 \\ 21 & - 17 & 4 & 8 \\ 2 & 8 & 27 & 30 \\ 5 & 15 & - 3 & - 10 \end{matrix}]$

Step 2.Find inverse matrix

By using graph utility inverse matrix is $[\begin{matrix} 0.01 & 0.03 & - 0.00 & 0.03 \\ 0.02 & - 0.02 & 0.01 & 0.01 \\ - 0.04 & 0.01 & 0.04 & 0.06 \\ 0.05 & - 0.02 & - 0.00 & - 0.09 \end{matrix}]$

Step 3.The solution

The inverse matrix is $[\begin{matrix} 0.01 & 0.03 & - 0.00 & 0.03 \\ 0.02 & - 0.02 & 0.01 & 0.01 \\ - 0.04 & 0.01 & 0.04 & 0.06 \\ 0.05 & - 0.02 & - 0.00 & - 0.09 \end{matrix}]$
