[flash cs4] Memory usage utility classes

I think I’m doing this right. I have a class just full of random STATIC functions and vars that I use often on alot of other classes. things like the classic randRange(min, max) function. . just silly things i dont want cluttering my code

My question is does importing this class into other classes increase the memory used by instances of the class. Cause i may import this class of 30 objects and only use 2 of them. I’m thinking it doesn’t. But i could be wrong as I haven’t found much material on flash memory usage other than garbage collector stuff.
