Answer:
A,C
Step-by-step explanation:
sin 2x=sin (x+x)=sinx cos x+cos x sin x=2 sin x cos x
or =2 cos x sin x
[sinx cox=cos x sin x ]
2)Since the score is 750, then the annual rate is 9.25% (see the table)
Then monthly rate:9.25/12=0.77%.
Then compute 0.77% from <span> $2,375.00 like this:
</span>

Answer: interest to pay: $18.30.
3)Compute monthly rate for first account:
9.75/12=0.81%
Compute 0.81% of $<span>1,675.00 like this:</span>

Second account:
compute monthly rate: 12.5/12=1.04%.
Then compute

Conclusion:
Monthly interest is $13.5+$17.4=$30.9
800n-3x=0 this is the answer help this helps
Answer:
C
Step-by-step explanation:
You have 2 totals so the number of males + females = 127 so x + y = 127
Then there are 23 more males than females, it did not say 23 times more so B is out, so the female number + 23 = male number so y + 23 = x
Therefore letter C is the answer.
