Open Question: ANYONE COULD ANSWER: HOW TO TAKE A PILL?
Once you've gotten pretty good at swallowing gel capsules, it'll be easier to swallow actual pills. You can't keep those in your mouth for very long, though, because once they start dissolving they taste terrible.
My best advice is to stop psyching yourself up and DO IT! I hope that helps. Good luck!

Open Question: does anyone know how to do this linear algebra ?
So start by finding the eigenvalues. If they're different, then A and B are not similar.
If they are the same, then find the eigenvectors and form a matrix with those eigenvectors as columns. Using the eigenvectors of A gives you a matrix that diagonalizes A. That is, let P1 be this matrix. Then
D = P1^(-1) A P1
where D is a diagonal matrix with the eigenvalues on the diagonal. Do the same thing with B. Since it has the same eigenvalues
D = P2^(-1) B P2, or B = P2 D P2^(-1)
So B = P2 P1^(-1) A P1 P2^(-1) and the matrix P you want is equal to P1 * P2^(-1).

Open Question: Has anyone had a bad experience using Ouija Boards?
we were playing with a ouija board on halloween night. the lights were off and we were using candles for illumination to maintain the mood. someone left a window open and a light breeze blew some of the hanging artificial spider webs into the candle and the drapes caught on fire.
the house burned down, we were left homeless for over a year, and during that time, mom and dad got divorced, the dog died, and we all almost died from pneumonia.

Open Question: Can anyone describe to me the difference between permutations and combinations for Algebra II?
The number of combinations is less: it's n!/((n-r)!r!). The order in which things are chosen is not significant.
1) There are 6 floats, and 3 choices are to be made among them. The order of selection matters, because the prizes are not the same: if floats A, B, and C win prizes, it matters whether A gets first prize, or B gets it, or C gets it.
So, use the permutation formula. n = 6 and r = 3, so the number of ways is 6!/(6-3)! = 720/6 = 120.
2) The order of selection does not matter here, since Nate wants to do both activities without having them be in any particular order.
So, use the combination formula. n = 7 and r = 2, so the number of ways is 7!/((7-2)!2!) = 5040/(120·2) = 21.
3) The order of selection does not matter here, since Gregory just wants to get 3 different boxes; it does not matter which one he picks up first.
So, use the combination formula. n = 5 and r = 3, so the number of ways is 5!/((5-3)!3!) = 120/(2·6) = 10.
Open Question: Does anyone know the name of this proof to the Pythagorean Theorem? PLEASE HELP!!!?
Open Question: Does anyone know a fun science experiment to do?
Open Question: Why are there so many genetic defects, how can anyone explain?
One thing you must keep in mind is that being human, we are far more interested in human disease than animal disease.
There are no animals that we know as well as humans. The only ones that even come close are those that are useful for scientific or agricultural uses.
