What Is The Rule Of Threes?
542947
The Rule of Threes is an uncomplicated way to remember the basic priorities of the human organism, and it is a good starting point for an exploration of survival priorities. The Rule of Three's looks like this:\n\nA person can live for:\nThree minutes without air.\nThree hours without shelter.\nThree days without water.\nThree weeks without food.\nThree months without love.\n\nLet's take a quick look at these priorities and try to understand the them a bit better.\n\nAir\nIf you can't breathe, make it so you can. If you can't make it so, die. End of story.\n\nShelter\nI frequently ask new survival students the question, "If you were lost in a blizzard without your gear what would you do?" The answer I hear most (and which confounds me), sounds something like this. "Build a fire and search for wild food." I can see it now: lost in a howling blizzard, the wind whipping the trees to rubble, frost forming on even the memories of warmth, while our hopeful survivor tunnels through snowdrifts in search of "wild edibles." I wonder if my Turkish friend was thinking of food when he laid down beside that boulder. Without proper shelter, he probably died within three hours.\n\nIt seems obvious our survivor must react immediately to the threat posed by the cold blowing storm. Only hours of life remain if the basic shelter needs are not met. Miserable and hungry, cold and scared, but alive if the shelter is properly constructed.\n\nThe wind dies, the snow moves from its horizontal path to one more nearly vertical and then stops altogether. The trees shiver as great blobs of storm-driven snow loosen and fall to earth. A patch of blue as the clouds part. Then the first muted mutterings of the forest are heard as signs of life begin to return. The hunched form of the rule-following survivor shoves aside parts of the hastily erected debris-shelter and he sets forth in quest of the next priority. Water.\n\nWater\nLike the sailor lost at sea with "water, water everywhere and not a drop to drink," our survivor first gobbles a handful of snow to help fill the rapidly developing vacancy in the hungry center. Oops. That won't do, either. It takes energy to turn snow into water. Snow may be only about 20% -30% water by volume yet it takes lots of energy to convert the cold snow into warm water. Where is the energy going to come from? No food to eat, and none in the stomach. There will be no power from the fat battery for some time. (It takes many hours to start receiving energy from our fat reserves. We need to stay alive until those reserves are available to us.) Our friend is still powered by the energy stored in the bones and blood. Water will be necessary to assist the energy extraction processes the body uses when converting fat into energy. Lack of water, the third priority, can stop us from utilizing even our own reserves. With dehydration we discover another interesting relationship between water and our chances for survival.\n\nFor each five percent our body dehydrates (by weight - i.e. a 100 pound body weight reduced to 95 pounds by dehydration), we lose approximately 25% of our ability to do work. Some authorities claim an even a greater loss of power.\n\nRemember, this is in addition to the loss of ability to do work caused by insufficient energy. The ratio of work energy lost versus the percentage of dehydration remains relatively constant until the victim is literally unable to continue to function. The percentages look something like this.\n\nPercentage of Dehydration and Ability to do Work:\n% of dehydration = % of work possible\n\n0% = 100%\n\n5% = 75%\n\n10% = 50%\n\n15% = 25%\n\n20% = 0%\n(possible death)\n\nWater is the third priority whether you find yourself at the ocean or in a snow storm. I ought to mention at this point that woodsmen and hunters sometimes find themselves uncomfortable and a little under the weather a day or two after the beginning of a trip. Often thi

The answer is 72.  You multiply the three numbers together.

You need to use the chain rule a couple of times.\nHow do you differentiate (something)^2 ? Make it 2*something. Then multiply by (something) differentiated.\nIn this case, (sin 3x)^2 differentiates to 2(sin 3x) * (sin 3x differentiated).\nNow, how do you differentiate sin(something)? Make it cos(something), then multiply by (something) differentiated.\nSo sin 3x differentiates to cos 3x * 3.\nOverall, you get 2 sin 3x cos 3x * 3 = 6 sin 3x cos 3x.

If you think #1 is a special case of the others, then add the value of #1 to the other three.  Likewise, as I read it, #5 excludes #2.

Do the game when the students can make one, two or three tally marks.  The object of the game is to make the last mark without going over.    The team gets a choice of going first, or choosing the number the game will go to.  \n\nThere is a pattern to the madness, but I want you to figure it out.

...\n3) The final standings of each group shall be determined by the first of the following\nmethods that apply:\na) Greatest number of wins;\nb) Greatest number of matches played;\nc) Head-to-head results if only two (2) players are tied, or if three (3) players are tied,\nthen:\ni) If three (3) players each have one win, a player having played less than all three(3) matches is automatically eliminated and the player advancing to the Single Elimination competition is the winner of the match-up of the two (2) players tied with 1-2 records; or\nii) Highest percentage of sets won; or\niii) Highest percentage of games won.\niv) If (i), (ii) or (iii) produce one superior player (first place), or one inferior player (third place), and the two remaining players are tied, the tie between those two players shall be broken by head-to-head record.\n4) If ties still exist after the above procedures, the Steering Committee shall make the final determination.

there are different reasons. 3 is a very powerful number in a lot of cultures. also, in fairy tales they like to isolate people, things, etc. having thins come in 3s allow them to create a patten, and then have the third person or thing break this pattern.

For any given triangle ABC with sides a, b and c.\n\nCos C = (a^2 + b^2 - c^2)/2ab  This is the cosine rule.\n\nSin C =sqrt(1 - Cos^2 C). You may need to adjust the sign of the sign to match the triangle.
