User question:
user: Alright, I've got a few tasks to take care of. I need to look up the slang definition of "Hello World" to settle a debate with my friend about programming jargon. While doing that, I also have to check the latest one-month stock history for Apple Inc. (AAPL), and I need the data to include dividends and stock splits. I'm working on a physics project too, so I need to figure out the density of an object that weighs 10 kilograms and occupies a space of 2 cubic meters. Oh, and for my math homework, can you help me organize these numbers in descending order: [5, 2, 9, 1, 7, 4, 6, 3, 8]?
