A man borrowed $ 10,000, at annual interest rate of 9 % with the understanding that interest was to paid monthly. However, the borrower did not make the monthly interest paymant and so the principal with interest at 9 % compounded monthly was due at the end of the year. What was the amount due??...

I believe the formula is : A = P(1+i) to exponent of "n"
where
n = tm
i = r/m

But i don't know howto solve it....
:(

Assume A,B,C are subsets of a universal set U, and define * as A*B=(A-B)union(B-A). Prove or disprove the following statement: A*B=B*A

I was able to show graphically that (A-B) union (B-A) do not intersect and same for (B-A)union(A-B) which are graphically equal but I couldn't prove it using procedural version of set definitions and identities. Also, I don't know how the subset C takes place in this proof.

Any help will be greatly appreciated!

If Un<---(suppose to read U sub n) represents the nth term of the Fibonacci sequence show that, Un and Un+1<---(suppose to read U sub n+1) are relatively prime. okay, I dont knoq how to start this, and what exactly does the "sub n and sub n+1" do to the U in this sequence I dont see a relation, because the sequence is 1,1, 2, 3, 5, 8,..., x, y, x+y, etc. How do I show these are prime by using what they are asking.

The topic is about "Simplifying Rational Algebraic Expressions"

1. x (squared) + 11x + 30
-------------------------------- = ?
3ax (squared) + 15ax

2. 4x (squared) - 1
--------------------------- = ?
2x (squared) - 5x - 3

3. an (squared) + 6an + 9a
---------------------------------- = ?
n (squared) - 5x - 3

4. 5x + 20
---------------------------- = ?
15x (squared) + 60x

lastly,

5. x + 1
----------------- = ?
x (cubed) - x

I hope that you get to help me. This is due on Monday. I'm really sorry if it is a bit tensing or something like that. I just can get it at all :( and please if some of you are just here to fool me or something then you're not welcome here. And if some of you are willing to help... thanks a lot!! <3
