0.41 / 10.20 = 0.040.....multiply by 100 to get ur percent = 4%
Answer:
Simplifying
lx2 + mx + n = 0
Solving
lx2 + mx + n = 0
Solving for variable 'l'.
Move all terms containing l to the left, all other terms to the right.
Add '-1mx' to each side of the equation.
lx2 + mx + -1mx + n = 0 + -1mx
Combine like terms: mx + -1mx = 0
lx2 + 0 + n = 0 + -1mx
lx2 + n = 0 + -1mx
Remove the zero:
lx2 + n = -1mx
Add '-1n' to each side of the equation.
lx2 + n + -1n = -1mx + -1n
Combine like terms: n + -1n = 0
lx2 + 0 = -1mx + -1n
lx2 = -1mx + -1n
Divide each side by 'x2'.
l = -1mx-1 + -1nx-2
Simplifying
l = -1mx-1 + -1nx-2

The cofunction of cos is sin(90-x)
90 degrees is equal to PI/2
The cofunction becomes sin(PI/2 - 2PI/9)
Rewrite both fractions to have a common denominator:
PI/2 = 9PI/18
2PI/9 = 4PI/18
Now you have sin(9PI/18 - 4PI/18)
Simplify:
Sin(5PI/18)
Okay, i don't want to give you the direct answer because i want you to know how to do it ... First you multuply $4.30 x .4 and you will get a number... remember that number in your head and subtract it from the original amount of $4.30... then once you get the number from subtracting the discount, multiply that number by .6..... then with that number, add the sales tax and there is your answer!
Let
The curl is
where 
denotes the partial derivative operator with respect to 
. Recall that
and that for any two vectors 
and 
, 
, and 
.
The cross product reduces to
When you compute the partial derivatives, you'll find that all the components reduce to 0 and
which means 
is indeed conservative and we can find 
.
Integrate both sides of
with respect to 
and
Differentiate both sides with respect to 
and
Now
and differentiating with respect to 
gives
for some constant 
. So
