sin 3 x = sin ( 3 x + 2 π ) = sin [ 3 ( x + 2 π/ 3 ) ] = sin 3 x
This means "after the arc rotating three time of ( x + ( 2 π /3 ) ) , sin 3x comes back to its initial value"
So, the period of sin 3x is 2 π /3 .
There is no way to solve for , but we can simplify the expression.
Distribute the to the .
Combine the like terms.
We cannot simplify further, so this is the answer.
14/2, 7 games per month.
Take the total amount of games and divide it by the time.
The new width would be 4 inches, because to get from 12 inches to 2 inches you need to divide by 6, which means you must divide 24 by 6 as well, which equals 4. I hope this helps!
