We have been given two matrices a and b. A has 6 rows and 7 columns, while b has 7 rows and 8 columns.
Since we know that order matters in matrix multiplication. In order for matrix multiplication to be defined number of columns in the first matrix should be equal to the number of rows of in the second matrix.
We can see that number of columns in matrix a and number of rows in matrix b is 7.
Therefore, size of ab will be equal to number of rows of matrix a and number of columns of matrix b that is 6 by 8.
Now we will see whether ba is defined or not. We can see columns in matrix b are 8 and rows in matrix a are 6, which is not equal. So we can say that ba is not defined.
Therefore, size of ba is not defined (dne).
Answer:
55 miles per hour
Step-by-step explanation:
605 miles ÷ 11
11 hours ÷ 11
=
55 miles
1 hour
=
55 miles
hour
Answer: It would be 13.0 hours.
Step-by-step explanation: It would be 13.0 hours because $11.00 times 13.0hours is $143.00 so just do 11*13 and you get 143.
