Answer:
Option A. is the correct option.
Step-by-step explanation:
We have to get the simplified form of sin (.6x)-sin(.4x)
As we know the identity sinA- sinB = 2 cos(A+B)/2.sin(A-B)/2
We apply the identity in the given expression
sin(.6x)-sin(.4x) = 2 cos(.6x + .4x)/2.sin(.6x - .4x)/2
= 2 cos(x/2).sin(0.2x/2) = 2 cos(0.5x).sin(0.1x)
Therefore option A is the correct option.
It's might be.....180,000 I'm sure
It's simple.
First multiply 3 by 4
It equals 12
Then, multiply 12 by 3
It equals 36
The answer is 36 different combinations.
