Answer:
-sqrt(3)/2
Step-by-step explanation:
Use double angle identity for sin(2x)
sin(2x)=2sin(x)cos(x)
We are given sin(x)=-1/2 so we already have so far that:
sin(2x)=2(-1/2)cos(x)
sin(2x)=-1*cos(x)
We just need to find cos(x).
x is in the fourth quadrant so cosine will be positive there
knowing the unit circle we should know that if sin(x)=-1/2 then cos(x)=sqrt(3)/2 while in 4th quadrant.
So the answer is sin(2x)=-1*sqrt(3)/2=-sqrt(3)/2
That's a lot of points for this question. You don't have to offer that much.
Leading Coefficient: When written in standard form (starting with the variable with the highest power, going to the variable with the next highest power ... all the way down to a number with no variable), the leading coefficient is the number in front of the variable with the highest power.
Let me put this less technically. Find the variable with the highest power. The number in front of that variable is the leading coefficient.
Write this in standard form. 5x^4 -2x + 1
The number in front of the x^4 is the answer.

Answer~35
Wørk~
2x10=20
20+15=35
Y = x + a number
or it can have numbers in front of the letters
