Question

Find the given elements of matrix d: d = -2 -4 2 0 6 4 -2 -2 -2 4 4 4. d11 = ?, d12 = ?, d13 = ?, d21 = ?, d22 = ?, d23 = ?

Answer 1

The student's question pertains to identifying specific elements within a given matrix. The elements d11, d12, d13, d21, d22, and d23 correspond to the values -2, -4, 2, 0, 6, and 4 respectively, based on their position in the matrix.

Step-by-step explanation:

The student is asking for the elements of a given matrix d. The elements are denoted by dij, where i represents the row number and j represents the column number. For the matrix:

`\left[\begin{array}{ccc}-2&-4&2\\0&6&4\\-2&-2&-2\\4&4&4\end{array}\right]`

The requested elements are as follows:

• d11 = -2 (Row 1, Column 1)
• d12 = -4 (Row 1, Column 2)
• d13 = 2 (Row 1, Column 3)
• d21 = 0 (Row 2, Column 1)
• d22 = 6 (Row 2, Column 2)
• d23 = 4 (Row 2, Column 3)
