Chapter 4: Q51. (page 188)

Use a graphing calculator to find the value of the following determinant.
$|\begin{matrix} 1.3 & 7.2 \\ 6.1 & 5.4 \end{matrix}|$

Short Answer

Expert verified

The value of the determinant is $- 36.9$ .

Step by step solution

Step 1- Apply the concept of determinant.

the determinant is a scalar value that is a function of the entries of a square matrix. It allows characterizing some properties of the matrix and the linear map represented by the matrix.

Step 2- Step description.

Consider the determinant $|\begin{matrix} 1.3 & 7.2 \\ 6.1 & 5.4 \end{matrix}|$ .

Use a graphing calculator and find the value of the determinant as follows:

$\begin{array}{l} = 1.3 (5.4) - (7.2) (6.1) \\ = - 36.9 \end{array}$

Step 3- Step description.

Therefore, the value of the determinant is $- 36.9$ .
