The idea being - say you move your fingers closer together. They start off a certain distance apart. They then get half the distance, then three quarters, then four fifths, etc. With the law of diminishing returns the fraction will get smaller and smaller and smaller - but even when they are 999999999/1000000000ths of the way there, they still wouldn't be touching. Surely the fraction just gets smaller, but the fingers never actually get there? How does anyone ever touch anything? Come to mention it, how does anything ever happen?

I have yet ANOTHER extra credit science project due at the end of the grading period. It's supposed to be a car that is TOTALLY hand-made and it has to go down a 3 1/2-4 ft piece of wood at about a 60 degree angle the slowest time possible. So, in other words, it will be slanting down (the highest point is about 3-4 ft. off of the ground) and it CANNOT fall off of the side....AND it has to get to the finish line (the end of the plank at the bottom) in the slowest time than anyone else to get a total of 5 points on the final grade. (That's , like, 25 points extra on a major test grade.) What should I make it out of?

A white powder, consisting of a simple mixture of tartaric acid (C4H6O6) and citric acid (C6H8O7) was analysed to determine the elemental composition. Combustion of a 433.7-mg sample produced 533.6 mg of CO2 and 158.0 mg of H2O.

Then I have to find the %C, H, O, etc. by mass. Can someone please explain this to me? Its my last question and I cant get it :(

the corporate statistician for the New York Yankees baseball team came up with the following formulain oreder to estimatethe probability that a randomly selected fan eats from 0 to three hot dogs at any Yankee game. use this model to estimate (to 2 decimal place accuracy) the mean number of hot dogs that an average fan would eat at a game. p(x)= (x -x2+7)/(20)
x2 is x squared...
