Problem

Consider the following matrix: \[ \text { Let } D=\left[\begin{array}{ccc} 8 & 3 & 11 \\ -12 & 1 & -3 \\ 5 & 2 & 6 \end{array}\right] \] Step 2 of 3 : Determine the value of $d_{22}$, if possible. If the element indicated is not in the matrix, state "None". Answer Keyboard Shortcuts 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. None

Solution

Step 1 :Consider the following matrix: \[ D=\left[\begin{array}{ccc} 8 & 3 & 11 \\ -12 & 1 & -3 \\ 5 & 2 & 6 \end{array}\right] \]

Step 2 :Determine the value of $d_{22}$, if possible. If the element indicated is not in the matrix, state 'None'.

Step 3 :The question is asking for the value of the element at the second row and second column of the matrix D. Looking at the matrix, we can see that the element at the second row and second column is 1. So, the value of $d_{22}$ is 1.

Step 4 :Final Answer: The value of $d_{22}$ is \(\boxed{1}\).
