*Official* The School Help Thread

Great for Math, Physics, Biology, Chemistry, and Finance/Economics: www.KhanAcademy.org

School is rapidly approaching (it may have already started for some of you) and I am trying to be proactive in avoiding 500 threads of "omg liek help with this school work!" There are many intelligent people on here who and are in/graduated from college and can help you with your high school homework. If you have trouble understanding something or just need help, this is the place to ask.

IF YOU POST A HOMEWORK/SCHOOL QUESTION OUTSIDE OF THIS THREAD, YOU WILL GET A 3 DAY TEMP BAN!

The Rules:
1. Do not copy your homework verbatim. We are here to help you, not do it for you. For example, if you don't get how to factor a trinomial, ask how to do one or two problems so that you get the general idea, but do not post all 15 you were assigned.
2. Do not answer stuff unless you know what you are talking about. Nobody is going to benifit from misinformation, so if you went to high school but got a "C" in European History, we don't need you to comment on the French Revolution. Generally speaking, unless you got an "A" or "B+" in the subject, you shouldn't try to teach it to others.
3. On the positive side, if you feel you are strong in a particular subject (and have FINISHED high school) and would not mind helping someone, PM me. I am going to compile a list of people who you can PM for help on certain subjects. UPDATE: I have a pretty good sized list so far, so unless you are good in a subject not listed already, just stick to helping people that post in the thread.
4. When helping someone, don't just give the answer, explain why it is the correct answer. This is especially helpful for math and English.
5. Use common sense.
6. Posting something in this thread that is A.) not a question or B.) not helping anyone will be deleted.

A list of people willing to help via PMs:

Subjects: None. Please stop PM'ing me, I rarely visit this board anymore. I probably won't answer. Ask another mod to edit this post for me.

Is anyone here familiar with qbasic? I ran into an issue on my program I'm writing I'm having issues with and would love some help.

HELP ME PLEASE!

This time you dump into the barrel 10 Ping-Pong balls numbered 1–10 as before and remove number 1. But next you put in 100 Ping-Pong balls, numbers 11–110, and remove number 2. Then you put in 1000 balls, numbered 111–1110 and remove number 3, and so on. The question is: How many Ping- Pong balls remain in the barrel after the stopwatch beeps? Infinitely many? Finitely many? Can you name one? Explain your answer clearly.

Let's say it takes you a minute to put in and take out the balls each time. So you can find the amount of balls at any minute using a summation.

If you model the problem using a summation:

"i" represents the value that you are counting from, I am starting at 1. "n" represents the number of minutes that have passed (assuming the stopwatch started at zero with zero balls and there were 9 balls in the barrel at 1 minute).

If you haven't covered summations yet, this is basically a way to represent this:


As you can tell, you are always going to be putting more balls in the barrel than you will be taking out. If the stopwatch runs for an infinite time, then there will be an infinite amount of balls in the barrel (assume the barrel is infinite in size). If you just want to find the amount of balls at a certain time, solve the summation for how many at that certain time.

So for example, if you want to find how many balls are in the barrel at 5 mins (or just 20 operations of putting in and taking out balls),



Hopefully this helps someone else since the post is over a month old.
