Answer: a) AB = ; b) ; c) No, they are different; d) No, they are never the same;
Step-by-step explanation:
a) A = , B = . This multiplication is possible, because matrix A has 2 columns and matrix B has 2 rows. When those value are equal, the multiplication is possible.
AB = . =
b) BA = . =
c) As, we can see, parts a and b are differents.
d) With matrices, multiplication is not commutative, which means AB≠BA
Answer:
x = -3: , x = -2: , x = -1: , x = 0: , x = 1: , x = 2: , x = 3:
Step-by-step explanation:
Let , where and are the independent and dependent variables, respectively. The approach consists in evaluating the function at values presented in statement:
x = -3
x = -2
x = -1
x = 0
x = 1
x = 2
x = 3
I would need the equations
Answer:
number of sides: 18 sides
<u>Explanation</u>:
Total Interior angle = ( n - 2 ) * 180°
Using the formula:
2880° = ( n - 2) * 180°
n - 2 = 16
n = 16 + 2
n = 18 sides
