I had a test yesterday n not sure if I did this question right:

Q:squareroot(x+y)=1+(x^2)(y^2)

I got the answer y'=[1/2(x+y)^(-1/2)-2x(y^2)]/2(x^2)(y)

(P.S: d/dx both sides and find dy/dx)

Thanks a lot

Here's the question:
"There are 12 stones. The diamond is embedded in one of the stones. Eleven of the stones weigh the same, but the stone containing the jewel weighs either slightly more or slightly less than the others. Find the right stone and find whether it's heavier or lighter. You could use each of the three balance scales exactly once.

Can anyone help me out? My boyfriend and me are working on this one and haven't solved it yet."

I know the answer. Now let's see if you can get it.

Solve this: 3 people went to a restaurant. After having the meal, they asked for the bill and the waiter brought them a bill of US$ 25 (long time ago -- food was cheaper). Each one gave the waiter a $10 bill. The waiter returned them 5 $1 bills. Each of the 3 people took one $1 bill and they left $2 on the table for the tip.

In summary: Each one paid $9. 3 times $9 equals $27. So, $27, plus $2, left as a tip, makes it $29. It's still $1 short for $30. Where did this $1 go?

One day while I was at school, the electricity went out at home. When I left for school that morning, all the clocks were working and agreed that the time was 6:30. When I got home they all said different times. The wind-up clock, which was unaffected by the electricity, read 5:21. The analog electric clock stops running when you unplug it from the wall, and it starts up where it left off when you plug it back in. That clock said it was 3:50. My digital electric clock, which resets itself to midnight when the electricity goes out, flashes until you correct the time. It was flashing 6:03am. Assuming the electricity went out just once, what time did it go out, and how long was it off.

if you have to find if a 3digit number is divivisable by 3, i.e. 345 or 696 add the numbers up then divide by 3 i.e. 345 = 13 not divisable 696= 21 / 3 equals 7 so it can be devided by 3


haha no real use just crap

The idea of randomness is abstract but has important applications in statistics, probability, numerical analysis, physics, and all the natural sciences. Quantum-mechanical descriptions involve probability distributions necessitating the idea of randomness; radioactive decay may be understood to occur in a predictable macroscopic way, but with an element of randomness in terms of an individual particle's timing of decay. Is it possible to generate a "true" random number, or are existing random number generators or algorithms always "pseudo-random"? Has anyone thought of using naturalistic observation to generate "true" random numbers; i.e. assuming the moment of decay for a particle is truly random, and monitoring decay rates systematically so as to generate a set of random numbers.
Maybe the terminology could be paradoxical, for example maybe the sequence of digits in a decimal expansion of an irrational number is "truly random" but is also precisely determinable.
