Answer:
The value of AB is and it's not possible to multiply BA.
Step-by-step explanation:
Consider the provided matrices.
,
Two matrices can be multiplied if and only if first matrix has an order m × n and second matrix has an order n × v.
Multiply AB
Matrix A has order 2 × 2 and matrix B has order 2 × 1. So according to rule we can multiply both the matrix as shown:
Hence, the value of AB is
Now calculate the value of BA as shown:
Multiply BA
Matrix B has order 2 × 1 and matrix A has order 2 × 2. So according to rule we cannot multiply both the matrix.
We can multiply two matrix if first matrix has an order m × n and second matrix has an order n × v.
That means number of column of first matrix should be equal to the number of rows of second matrix.
Hence, it's not possible to multiply BA.

Answer:
The magnitude is 2093.4 lbs. The direction is 40N of W.
Step-by-step explanation:
To find the magnitude you have to do a^2 + b^2 = c^2 seeing as the two other sides would make the two legs of a right triangle.
To find the direction, you do tan^-1 (1350/1600) in order to find the degree.
