Answer:

The dimensions ⇒ 3 × 4

Step-by-step explanation:

* Any matrix has two dimensions

- Raw and column

- The dimensions very important in the operations on matrices

- We called the number of raw m and the number of column n

- We must write the number of raw before the number of column

- m × n is the dimensions of the matrix

* Example : If the dimension of a matrix is 2 × 3, that

  means the matrix has 2 raw and 3 column

* Now lets look to our problem

∵  It has 3 raw and 4 column

∴ Its dimensions is 3 × 4

<u>Answer:</u>

Size of matrix = 3 × 4

<u>Step-by-step explanation:</u>

We are given the following matrix and we are to determine its dimensions:

\left [ \begin {array}{cccc} 1&-3&8&4\\7&5&3&0\\9&6&-2&-1 \end { array } \right ]

We know that the dimension of a matrix is written in the form:

<em>rows × columns</em>

Here we have 3 rows and 4 columns. Therefore, the size of this matrix is 3 × 4.

HELP HELP !!!! PLEASE I NEED HELP WITH THIS PROBLEM !!!
Vesnalui [34]
This one is best done by elimination:

We need to start 4 meters away, so B is clearly wrong. 

We first move towards Mr. Wilson (i.e. distance is decreasing) so A is wrong.

Our speed is faster on the way back, so the two sloped section must have differing slopes, so D is wrong.
(D also doesn't start at 4, it's wrong for two reasons.)

Only C is left.

We can check each part to make sure. First we start at 4m, then move away, then stay still (zero slope) for three seconds, then move back faster (higher slope). All parts check out ok.
