What is the product
djverab [1.8K]

Answer:

The product of given matrix is AB=\begin{pmatrix}7\\ 4\\ 2\end{pmatrix}

Step-by-step explanation:

Given : Two matrix

A=\begin{pmatrix}3&6&1\\ 2&4&0\\ 0&6&2\end{pmatrix}

and B=\begin{pmatrix}2\\ \:0\\ \:1\end{pmatrix}

We have to find the product of given matrix

AB=\begin{pmatrix}3&6&1\\ 2&4&0\\ 0&6&2\end{pmatrix}\begin{pmatrix}2\\ 0\\ 1\end{pmatrix}

Multiply the rows of first matrix by the columns of second matrix , we have,

\begin{pmatrix}3&6&1\end{pmatrix}\begin{pmatrix}2\\ 0\\ 1\end{pmatrix}=3\cdot \:2+6\cdot \:0+1\cdot \:1

\begin{pmatrix}2&4&0\end{pmatrix}\begin{pmatrix}2\\ 0\\ 1\end{pmatrix}=2\cdot \:2+4\cdot \:0+0\cdot \:1

\begin{pmatrix}0&6&2\end{pmatrix}\begin{pmatrix}2\\ 0\\ 1\end{pmatrix}=0\cdot \:2+6\cdot \:0+2\cdot \:1

=\begin{pmatrix}3\cdot \:2+6\cdot \:0+1\cdot \:1\\ 2\cdot \:2+4\cdot \:0+0\cdot \:1\\ 0\cdot \:2+6\cdot \:0+2\cdot \:1\end{pmatrix}

On , simplifying , we get,

AB=\begin{pmatrix}7\\ 4\\ 2\end{pmatrix}

Thus, the product of given matrix is AB=\begin{pmatrix}7\\ 4\\ 2\end{pmatrix}

I just started learning about rate and I am stuck on a question.(A watch keeps perfect time but only has an hour hand. If the ho
8090 [49]

Answer:

36 minutes past 1, or 1:36

Step-by-step explanation:

A watch normally has an hour hand that does one revolution in 12 hours.

It takes 1 hour to go from the 1 o'clock position to the 2 o'clock position.

Since 1 hour equals 60 minutes, it takes 60 minutes to go from the 1 o'clock position to the 2 o'clock position.

The hour hand is 3/5 of the way from 1 to 2, so the number of minutes past 1 o'clock is 3/5 of 60 minutes.

3/5 of 60 minutes =

= 3/5 * 60 minutes

= 3/5 * 60/1 minutes

= 180/5 minutes

= 36 minutes

The time is 36 minutes past 1, or 1:36

-15 + 12x = 5x + 7 -3x<br> SOLVE FOR X
Natali [406]

Answer: x=\frac{11}{5}

<u>Simplify both sides of the equation</u>

<u></u>-15+12x=5x+7+-3x<u></u>

<u></u>12x-15=(5x+-3x)+(7) (Combine Like Terms)

12x-15=2x+7

<u>Subtract 2x from both sides</u>

<u></u>12x-15-2x=2x+7-2x\\10x-15=7<u></u>

<u></u>

<u>Divide both sides by 10</u>

<u></u>\frac{10x}{10} =\frac{22}{10}<u></u>

<u></u>x=\frac{11}{5}<u></u>

<u></u>
