Answer:
option C
Step-by-step explanation:
given,
A and B are arbitrary 2×2 matrices
we need to find
(A+B)²
(A+B)² = (A+B)(A+B)
(A+B)² = A.A + A.B + B.A + B.B
(A+B)² = A² + A.B + B.A + B²
Matrix multiplication does not follow multiplicative law
AB ≠ BA
(A+B)² = A² + A.B + B.A + B²
now,
(A+B)² = A(A+B)+ B(A+B)
the correct answer is option C
Answer:
y = -¼│x − 5│+ 3
Step-by-step explanation:
y = a│x − h│+ k
(h, k) is the vertex of the absolute value graph. In this case, it's (5, 3).
y = a│x − 5│+ 3
One point on the graph is (1, 2). Plug in to find the value of a.
2 = a│1 − 5│+ 3
2 = 4a + 3
a = -¼
Therefore, the graph is:
y = -¼│x − 5│+ 3
Answer:
Angle C measures: 
Step-by-step explanation:
When you know the length of the three sides of the triangle and not a single angle, the law of sines is of no use. You need to use the law of cosines. In your case, since you want to find angle "C", you use the following;
1(3694820-1223400=2471420. Ans. B
2)4*40*0.05=8 Ans. B
3)Ans. D
4)2*3*2*3=6*6=36 Ans. 2,2,3,3
5)4*(10)/2=40/2=20 Ans 20
6) Ans. Distributive Property
7)Ans. 5
8)Ans. 60° angle, because 90-30=60
