First Graph (The left-most graph)
Step-by-step explanation:
Answer:
sin^2(45) = (√2/2)^2 = 1/2
Step-by-step explanation:
sin2x = sin2 * x = 0.909x
sin(2(45)) = sin90 = 1
Hope this helps.
2a + 3b = 6
5a + 2b = 4
We multiply the first equation by 5 and the second by 2 and and subtract the second from the first:
10a + 15b = 30
-10a -4b = -8
11b = 22
b = 2
2a + 3(2) = 6
2a = 0
a = 0
Checking,
5(0) + 2(2) = 4
4 = 4, true
Answer:
Option A is the right answer.
146-4b = 122-1b
Reason: vertical angles
Answer:
5n-t/7
Step-by-step explanation:
The product of 5 and n puts them in the same category and product means times and your going to minus t divided by 7
