Answer:
$10
Step-by-step explanation:
The exact number is $11.65 which is closet to $10
There is a trig identity called the sum of 2 angles for sin its<span>
sin(a+b)=sin(a)cos(b)+cos(a)(sin(b)
</span>
You will need to use it. So in your question split the 4x in 2 equal parts 2x and 2x
<span>
</span><span>sin(4x)=sin(2x+2x)
</span>Now using the expansion above you will get
<span>sin(2x+2x)=sin(2x)×cos(2x)+cos(2x)×sin(2x)
</span>And it will simplify to
<span><span>2sin(2x)cos(2x)
I hope this helps you! Good luck :)</span></span>
Answer: Push factors encourage people to leave their points of origin and settle elsewhere, while pull factors attract migrants to new areas. For example, high unemployment is a common push factor, while an abundance of jobs is an effective pull factor.

Answer:
1227 is correct ................................................
Step-by-step explanation:
First draw is 6 out of 10 = 6/10 = 3/5
Second draw is 5 girls out of 9 remaining children = 5/9
Now we multiply the probabilities:
3/5 x 5/9 (you can cancel out the 5's since one is in the numerator and the other is in the denominator. You can also reduce the 3 and 9. The answer is 3/9=1/3
So the chances that the first two selected will be girls is 1/3.
