Question

consider the following matrix:
let ( a = \begin{bmatrix} 27 & -30 \\ -34 & 21 \\ -31 & -40 \\ -28 & -2 \\ -20 & -1 end{bmatrix} )
step 2 of 3 : determine the value of ( a_{52} ), if possible. if the element indicated is not in the matrix, state
one\.
answer
selecting a radio button will replace the entered answer value(s) with the radio button value. if the radio button is not selected, the entered answer is used.
( square ) ( \bigcirc ) none

Explanation:

Step1: Identify element position

The notation $a_{ij}$ refers to the element in the $i$-th row and $j$-th column of matrix $A$. For $a_{52}$, we look for the 5th row, 2nd column.

Step2: Locate the element

In matrix $A$, the 5th row is

$$\begin{bmatrix}-20 & -1\end{bmatrix}$$

. The 2nd element of this row is $-1$.

Answer:

$-1$
