She taught it, but i didn't really understand it, I asked for help, I guess she tried her best to help me, but I really didn't understand it. So I asked one of my friends around me for help, and all they did was right down the answer for me! THATS NOT HELP! I want to learn how to do it myself

so could you help me solve these, and show me how you got them?

THANKS!!

Real Analysis:

Prove the intrsection interval from n=1 to infinity (0,1/n)=empty. (cant really do the intersection notation)... Notice that this demonstrates that the intervals in the nested interval property must be closed for the conclusion of theorem to hold.

Thanks!!

Prove for all n that exist in N (all natural numbers),
0 squared + 1 squared + 2 squared + ... + n squared =
n(n+1)(2n+1) all divided by 6.

I've gotten to the base case, but after that I'm lost on what to do for the inductive step.

Any help would be greatly appreciated. Thanks.

ok so i do not the answer to this so far everyone i have asked didnt know the answer either.

3 guys went to rent a hotel room and it was 30 dollars. each gave 10 dollars in. later the manager figured out that the room they were in was only 25 dollars so he sent a kid to give the men their money. the kid kept 2 dollars and gave each man 1 dollars back.

ok so if i lost you 10x3=30 but they each got a dollar back so they each gave 9 dollars. 9x3= 27 + the 2 dollars the kid took = 29 where is the other dollar to make it 30 dollars
