An estimate always makes sense.

-- I have $10 in my pocket, this pump says $2.21 a gallon, and my car has been getting about 29 mpg. How many miles can I buy ?

-- I'm responsible for the reading two weeks from next Saturday. I'm about 1/3 of the way through learning 190 lines. How many lines must I average learning each day from now til then ?

-- I'm 32 miles from home and rush hour is srarting to build. My wife wants to know when I'll be there. What shall I tell her ?

What is the product?

victus00 [196]

Answer:

$\begin{bmatrix}-2\\0 \end{bmatrix}$

Step-by-step explanation:

We have the product, $2\times \begin{bmatrix}-1\\0 \end{bmatrix}$ .

It is known that,

'When we multiply a scalar with a matrix, the scalar is multiplied by each element of the matrix'.

So, we get,

$2\times \begin{bmatrix}-1\\0 \end{bmatrix}$ .

⇒ $\begin{bmatrix}-1\times 2\\0\times 2 \end{bmatrix}$

⇒ $\begin{bmatrix}-2\\0 \end{bmatrix}$

So, the resulting product is $\begin{bmatrix}-2\\0 \end{bmatrix}$ .
