Three men checked into a hotel room and were charged $30 for which they paid $10 each. The next day, the manager realized that the men had been overcharged since the real price is $25 for the room. The manager gave the bellhop $5 to return to the three men. On the way to their room the bellhop decided to keep $2 for himself so he wouldn't have to make change. The bellhop gave $1 to each man. The three men had now paid $9 each, or a total of $27. This, plus the $2 the bellhop kept for himself, makes a total of $29. What happened to the other dollar?

Take the reimann sum for f(x) from 0 to 3 with 6 terms using right endpoints.
would that be .5(f(.5)+f(1)+f(1.5)+f(2)+f(2.5)+f(3))
the equation is x-4sin(2x) and i figured the answer to be 4.517743(it should be to six decimal places) but that answer is wrong!! help please

The Universe evacuated down to zero inches of vacuum with particles and Matter that can be charged and un-charged in this type of space. ( The Birth of Creation ) Engineered and designed by God himself.. I believe God created the Universe, because of the way the universe works. It's a too perfect engineered design to just have happened by chance...
