What is the product?

kobusy [5.1K]

Answer:

$\begin{bmatrix}7\\ 4\\ 2\end{bmatrix}$

Step-by-step explanation:

We have the product, $\begin{bmatrix} 3& 6& 1\\ 2& 4& 0\\ 0& 6& 2\end{bmatrix}\times \begin{bmatrix}2\\ 0\\ 1\end{bmatrix}$ .

As, we have the product of a 3×3 and 3×1 matrix, the resultant matrix will be of order 3×1.

So, we get,

$\begin{bmatrix} 3& 6& 1\\ 2& 4& 0\\ 0&6&2\end{bmatrix}\times \begin{bmatrix}2\\ 0\\ 1\end{bmatrix}$

⇒ $\begin{bmatrix}3\times 2+6\times 0+1\times 1\\ 2\times 2+4\times 0+0\times 1\\ 0\times 2+6\times 0+2\times 1\end{bmatrix}$

⇒ $\begin{bmatrix}7\\ 4\\ 2\end{bmatrix}$ .

Thus, the resulting product is $\begin{bmatrix}7\\ 4\\ 2\end{bmatrix}$ .
