-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)

Answer:
2.4 or 2 remainder 2
Step-by-step explanation:
12/5 = 2.4
F(x) = mx + c
f(x) = 3x + 4
The number of different codes does this lock provides is 360.
Given that,
- There is the combination lock having push buttons from A to F (6 buttons)
- Out of this, four should be in any order.
- Also, the push button should not be used more than once.
Based on the above information, here we use permutation which is as follows:

= 360
Therefore we can conclude that the number of different codes does this lock provides is 360.
