This is a philosophical question. If you can always ask yourself the question of ...what was going on 10 billion years before, no matter where you are in time, suggests that time goes back infinitely. If this is true then how did we ever get to this point in time?

Would all the numbers over 5 (infinity) be the same as all the numbers over 10 (also infinity)? I'm trying to prove to my math teacher that it would be. Does anybody have a credible link or something?

I have always wondered this. I don't save my coins in a jar, instead I always spend my coins whenever possible. Let's assume that I buy items with random prices. Let's also disregard .50 pieces. I also will give the cashier 3 cents for something that cost $2.78 in order to get less coins back (if I didn't have 3 quarters at the time). I suppose other "rules" might have to be stated in order to calculate the average, but I don't know what rules to state. I simply try to keep the amount of change I have to a minimum. I also try to keep the number of coins transferred from myself or to myself to a minimum.

Estimate the acceleration you subject yourself to if you walk into a brick wall at a normal walking speed. (Make a reasonable estimate of your speed and of the time it takes you to come to a stop, and explain those numbers also.)

A student obtanied a clean dry glass- stoppered flask. She weighed the flask and stopper on an analytical balance and found the total mass to be 31.601 g. She then filled the flask with water and obtained a mass fpr the full stoppered flask of 60.735 g. From these data, and the fact that at the temperature of the laboratory the density of water was 0.9973 g/cm3, find the volume of the stoppered flask.
Mass of water=______________g-________g=_________g
