Answer:

\left[\begin{array}{cc}7&1\\3&-3\end{array}\right]

Step-by-step explanation:

We simply add entry of each column of matrix 1 with its corresponding column entry of second matrix.

= \left[\begin{array}{cc}3&1\\0&-2\end{array}\right] + \left[\begin{array}{cc}4&0\\3&-1\end{array}\right]\\= \left[\begin{array}{cc}3+4&1+0\\0+3&-2+(-1)\end{array}\right]\\=\left[\begin{array}{cc}7&1\\3&-3\end{array}\right]

For this case we must add the following matrices:

\left[\begin{array}{ccc}3&1\\0&-2\end{array}\right]

And

\left[\begin{array}{ccc}4&0\\3&-1\end{array}\right]

Adding up:

\left[\begin{array}{ccc}3+4&1+0\\0+3&-2+(-1)\end{array}\right]=\\\left[\begin{array}{ccc}3+4&1+0\\0+3&-2-1\end{array}\right]=\\\left[\begin{array}{ccc}7&1\\3&-3\end{array}\right]

Answer:

\left[\begin{array}{ccc}7&1\\3&-3\end{array}\right]

4. Which rotation about the origin of line segment MN results in line segment M’N’?
olganol [36]

For this, let's examine the options, if it is A, with a rotation of 45 ° clockwise, you would have the following

If it is C or D, with a 180 ° rotation in a clockwise or counterclockwise direction, the segment would remain the same.

Finally, let's examine the option, B with a 90 ° rotation clockwise, you have the following.

Therefore, the correct answer is B. A 90° clockwise rotation.

A cone has a volume of 3 pi and a radius of 1 what is its height
alexgriva [62]

Answer:

The answer should be 2

Step-by-step explanation:

16 pi    = 1/3  pi    r^2    ( 12)        Divide both sides by pi

16        = 1/3        r^2     (12)         1/3   * 12 = 4

16         = 4          r^2                     divide both sides by 4

4           =             r^2                     You should be able to take it from here !

Find the common ratio of the geometric sequence: -320,80,-20,5
Flauer [41]

Answer:

-1/4 if you prefer the answer written as a fraction.

-0.25 is you prefer the answer written as a decimal.

Step-by-step explanation:

Common ratio of a geometric sequence can be found by doing term divided by previous term.

That is you could do:

80/-320

or

-20/80

or

5/-20

If all these ratios are not equal, it isn't a geometric sequence and does not have a common ratio.

Let's see what these reduce to:

80/-320=1/-4 =-1/4 or -0.25

-20/80=-1/4 or -0.25

5/-20=1/-4=-1/4 or -0.25

So the common ratio is -0.25 or yo you can write it as -1/4.
