Question 1163777
you would use the dot product to multiply a 3 row 2 column matrix by a 2 row 1 column matrix.


your result matrix will be a 3 row 1 column matrix.


your two matrices are:


<pre>

first matrix.

13.45      6.25
13.50      10.5
15         8

second matrix.

2
12

result matrix.

101.9
153
126

</pre>


the procedure will be as follows:


row 1 column 1 of the result matrix is equal to 2 * 13.45 + 12 * 6.25 = 101.9 
row 2 column 1 of the result matrix is equal to 2 * 13.50 + 12 * 10.5 = 153
row 3 column 1 of the result matrix is equal to 2 * 15 + 12 * 8 = 126
