I assume you're supposed to establish the identity,
cos(A) cos(2A) cos(4A) = 1/8 sin(8A) / sin(A)
Recall the double angle identity for sine:
sin(2<em>x</em>) = 2 sin(<em>x</em>) cos(<em>x</em>)
Then you have
sin(8A) = 2 sin(4A) cos(4A)
sin(8A) = 4 sin(2A) cos(2A) cos(4A)
sin(8A) = 8 sin(A) cos(A) cos(2A) cos(4A)
==> sin(8A)/(8 sin(A)) = cos(A) cos(2A) cos(4A)
as required.
I Believe it would remain the same unless there is a fee for converting the dollar to yen in the first place.
Answer: -48m + 56
Step-by-step explanation:
-8x 6m= -48m
-8x-7= 56
Here we have to use the fact that the domain of the function is equal to the range of the inverse function and range of the function is equal to the domain of the inverse function .
The range of the function is given . It means, the domain of the inverse function is given .
Correct option is the last option .
Answer:
1. Concert or Zoo
2. 32 people
3. 40%
Step-by-step explanation:
1. Concert or Zoo because they have the most votes
2. 200/25=8 8*4=32
3. 8 times 10 = 80 80/200=0.4 0.4= 40%
