Answer:
n(AUB)=n(A)+n(B)–n(AnB)
n(AUB)=n⁰(A)+n⁰(B)+n(AnB)
Step-by-step explanation:
This is the formula i have learned. Hope this will help u. U can use them according the question type.
Answer:
12n+2
Step-by-step explanation:
w(n)=4n+2
w(3n)=4(3n)+2
w(3n)=12n+2
7) A. 1.8

Answer:
0.75
Step-by-step explanation:
What is the given matrix?
you didn't show a matrix.
the components of the matrix are the elements.
and the elements of the inverse matrix are the elements of the inverse matrix
1)
so if matrix A is 1 4 1
2 5 2
3 6 3
2)
14114
25225
36336
3)
15 24 12
15 12 24
4)
[A]=(15+24+12=51)-(15+12+24=51)
[A]=0
5)
52 23 25
63 23 36
41 11 14
63 33 36
41 12 14
52 12 25
6)
15-12 6-6 12-15
12-6 3-3 6-12
8-5 2-2 5-8
7)
3 0 -3
6 0 -6
3 0 -3
8)
(+)3 (-)0 (+)-3
(-)6 (+)0 (-)-6
(+)3 (-)0 (+)-3
=
3 0 -3
-6 0 6
3 0 -3
9)
3 -6 3
N= 0 0 0
-3 6 -3
10) the inverse of [A]= 1/|A|*[N]
which is in this case ⁻A= 0
because |A|=0
