The correct answer is the second choice
It will be 57 because if 9 are nickles in the rest are pennies
Sin^5 x = <span>1/16 (10 sin(x) - 5 sin(3x) + sin(5x))</span>
I'm assuming those are two fractions being divided. I just write it out. It looks scary but it's really not. Just do this:
~=this is my dividing sign when not in fraction form cause I don't have an actual sign here.
9/14 ~ 5/12
Then you KCF(Keep, Change, Flip). Keep the first number the same. Change the dividing sign to multiplication. Then flip the last fraction so that it is now 12/5.
The problem now stands as:
9/14 • 12/5
Simplify and the you have your final answer. I recommend looking up the keep change flip video by flocabulary in case you haven't checked it out yet. It really helped me learn this method. Hope this helped!!
