Solve this if you can:
Let x = (1 + 1/2002)^2002 and let y = (1 + 1/2002)^2003

Find (x^y)/(y^x)

The 8" pizza sells for $ 4.99 at my favorite pizza store. The store claims they have a great deal on the large 14" pizza, which is specially priced at $ 11.5. What is the per cent discount the store is offering?

A large water tank has two inlet pipes (a large one and a small one) and one outlet pipe. It takes 2 hours to fill the tank with the large inlet pipe. On the other hand, it takes 6 hours to fill the tank with the small inlet pipe. The outlet pipe allows the full tank to be emptied in 8 hours.

What fraction of the tank (initially empty) will be filled in 1.38 hours if all three pipes are in operation? Give your answer to two decimal places.

Well, thanks for the people answer me the differentiation on f(x)=x!. I have been convinced with your answer that it is not a continuous function, thus can't be differentiated. so now please help me on the following question,

f(t) = (A)^t x tC(t/n)

where A<0, n>0
prove that when t approache to infinity, f(t) will approach to 0.

Note: tC(t/n) means the number of combination choosing t/n from t. t =kn where k is a integer (no decimal).

I will put your name into my paper if you can solve it. Thanks.

Here's an example. I see a pair of jeans that are 25% off and the regular price is, let's say $29.99. How do I figure out the cost once I take away the 25%? And how do I do the tax thing if here the tax is 8 cents?
