15 14
-1 9
Step-by-step explanation:
Given in the question a 2x3 and 3x2 matrix
Since, the column of first matrix and row of second matrix is of equal integer, 3, so we can multiply them.
The resultant matrix will be of 2x2
We will use dot product
1(2) + 3(3) + 1(4) 1(-2) + 3(5) + 1(1)
-2(2) + 1(3) + 0(4) -2(-2) + 1(5) + 0(1)
15 14
-1 9
So the way to answer this question is to convert minute to seconds
We know that a minute has 60 seconds
The problem states that the hummingbird flaps its wings 80 times per second
So 80 times per second x 60 seconds = 4800 times would be the final answer.
