To calculate the sales tax that is included in a company's receipts from items subject to sales tax, divide the receipts by 1 + the sales tax rate. For example, if the sales tax rate is 6%, divide the total amount of receipts by 1.06. If the sales tax rate is 7.25%, divide the total receipts by 1.0725.

me too.

lets see...

1/8x+3y=3

We turn it into linear by moving the variable and the number:

1/8x=3-3y

1/8x-3=-3y

then we turn the -3y into y:

-1/24+1=y !

slope (or gradient)=-1/24

(I don't know if I am  right.)

Um... Where are the numbers?

z = (5 - 3i)^(1/3)

Algebraic form:
z = 1.7707675-0.3224815i

Exponential form:
z = 1.7998922 × ei (-10°19'16″)

Trigonometric form:
z = 1.7998922 × (cos (-10°19'16″) + i sin (-10°19'16″))

Polar form:
r = |z| = 1.79989
φ = arg z = -10.32125° = -10°19'16″ = -0.05734π
 

THIS IS THE ACCURATE SOLUTION. THE FIRST ANSWER CALCULATED (5-3i)^1*3

Put to at the end so it makes sense. (I Don't know I'm putting grammar here)

5555555555555+555555555555555+555555555555555555555555+55555555555555555=

555555611672222222222220

=555555611672222222222220

The answer is more than 5. :)

I have to agree with melody. :/

3+i is technically 3+sqrt(-1)

so the answer iiiiissssss

3+i=3+sqrt(-1)

I think there may be some sarcasm in your last post Ally.  

You have over reacted to everything.

Lance was not teasing you, he just saw a great opportunity for a bit of word play fun.

His post was HILARIOUS!

Hayley was just showing appreciation of Lance's humour!

Lighten up and enjoy the forum.  Stop thinking that people are out to get you!
