Hi
we know that sin(A+B)=Sin(A)Cos(B)-Cos(A) Sin (B)
cos(2x)=1-2sin²(x)
sin(2x)=2sin(x)cos(x)
Exp:- Sin(3x)=Sin(x+2x)
Sin(x)cos(2x)+cos(x)sin(2x)
sin(x){1-2sin²(x)}+2cos²(x)sin(x)
sin(x)-2sin³(x)+2sin(x){1-sin²(x)}
sin(x)-2sin³(x)+2sin(x)-2sin³(x)
3sin(x)-4sin³(x)
Hope it helps....
Answer: Choice A) If the value of b is increased from 0, the graph moves up.
Explanation:
This line is of the form y = mx+b where b is the y intercept. Right now, the graph shows b = 0.
If we increase b to say b = 4, then the red line would cut through 4 on the y axis. So the line would move upward.
Answer:
Lee has $2 and 40 cents.
Step-by-step explanation:
Two $1 dollar bills equal $2 dollars
A dime is worth ten cents, therefore 10 x 4 = 40 cents.
That would all equal to $2 dollars and 40 cents.
3 dozen=3·12=36
Use cross multiplication
1/3·36=5x
12=5x
12/5=5x/5
x=12/5 or 2 2/5 or 2.4
12/5 or 2 2/5 cups of flour is needed to make 3 dozen rolls
