| | Raspberry Ketone is a health supplement. It comes from those delicious raspberries we can discover inside the grocery aisle. Yet, we can't receive enough of these small berries to get the full impact of them. Researchers say that it would take 90 pounds of these raspberries to receive the full benefit that comes in their pill shape.<br><br>I drank the tea beginning the first day of giving up caffeine. I did not drink any Dr. Zevia with caffeine or my usual black unsweetened tea with caffeine. I wondered if I would still have caffeine withdrawal headaches, moodiness and insomnia.<br><br>raspberry ketone works from the enzyme lipase. This helps to free fatty acids within the fat mobile inside time of fat utilization. And the presence of raspberry ketone in the program minimizes the enzyme heighten and therefore improves the amount of fat release. So if you are already following a training system to get rid of weight you are able to add a raspberry ketone supplement that is truly helpful to release fatty acids from the cells.<br><br>It is found which obese individuals have harmful dietary patterns. These people eat too much in comparison to what an average individual would eat throughout food. With the passage of time, the appetite of overweight people seems to grow. So, without control over the diet, how could you get the desired weight reduction even after following a daily exercise regime. Diet pills which actually function without rigorous exercise act as appetite suppressants plus assist to do away with fat in a healthy means.<br><br>If youre not sure about utilizing Absonutrix [http://safedietplansforwomen.com/raspberry-ketones raspberry ketones], thats ok, theres a lot of skeptics available.

As fat is broken down, poisonous acidic chemicals, called ketones, are released into the bloodstream.<br><br>On a few of the days, I would remain longer at the gym and frequently instances, train full contact boxing plus Muay Thai. I would moreover shadow box and a great deal of cardio/cross training exercises outside of the gym.

| == Evolution of the glyph ==
| |
| {{See also|Hindu-Arabic numeral system}}
| |
| According to Georges Ifrah, the origin of the 9 integers can be attributed to the ancient Indian civilization, and was adopted by subsequent civilizations in conjunction with the [[0 (number)|0]].<ref>{{cite book|title=From One to Zero: A Universal History of Numbers|year=1985|author=Georges Ifrah|publisher=Viking|isbn=0-670-37395-8}}</ref>
| |
| | |
| [[File:Evo9glyph.svg|x50px|right]]
| |
| In the beginning, various Indians wrote 9 similar to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a [[3 (number)|3]]-look-alike. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the ''@'' character encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic.
| |
| | |
| While the shape of the 9 character has an [[Ascender (typography)|ascender]] in most modern [[typeface]]s, in typefaces with [[text figures]] the character usually has a [[descender]], as, for example, in [[File:TextFigs196.png]].
| |
| | |
| This numeral resembles an inverted ''6''. To disambiguate the two on objects and documents that can be inverted, the 9 is often underlined, as is done for the 6. Another distinction from the 6 is that it is often handwritten with a straight stem.

| Nine is a [[composite number]], its proper [[divisor]]s being [[1 (number)|1]] and [[3 (number)|3]]. It is 3 times 3 and hence the third [[square number]]. Nine is a [[Motzkin number]]. It is the first composite [[lucky number]], along with the first composite odd number.
| |
| | |
| Nine is the highest single-digit number in the [[decimal|decimal system]]. It is the second non-unitary square [[prime number|prime]] of the form (p<sup>2</sup>) and the first that is odd. All subsequent squares of this form are odd. It has a unique [[aliquot sum]] [[4 (number)|4]] which is itself a square prime. Nine is; and can be, the only square prime with an aliquot sum of the same form. The [[aliquot sequence]] of nine has 5 members (9,4,3,1,0) this number being the second composite member of the 3-aliquot tree. It is the aliquot sum of only one number the discrete semiprime [[15]].

| There are nine [[Heegner number]]s.<ref>Bryan Bunch, ''The Kingdom of Infinite Number''. New York: W. H. Freeman & Company (2000): 93</ref>
| |
| | |
| Since 9 = 3<sup>2<sup>1</sup></sup>, 9 is an [[exponential factorial]].
| |
| | |
| 8 and 9 form a [[Ruth-Aaron pair]] under the second definition that counts repeated prime factors as often as they occur.
| |
| | |
| In bases 12, 18 and 24, nine is a 1-[[automorphic number]] and in base 6 a 2-automorphic number (displayed as '13').
| |
| | |
| A [[polygon]] with nine sides is called a [[nonagon]] or enneagon.<ref>Robert Dixon, ''Mathographics''. New York: Courier Dover Publications: 24</ref> A group of nine of anything is called an ennead.
| |
| | |
| In [[decimal|base 10]] a positive number is divisible by nine [[if and only if]] its [[digital root]] is 9.<ref>[[Martin Gardner]], ''A Gardner's Workout: Training the Mind and Entertaining the Spirit''. New York: A. K. Peters (2001): 155</ref> That is, if you multiply nine by any [[natural number]], and repeatedly add the digits of the answer until it is just one digit, you will end up with nine:
| |
| | |
| * 2 × 9 = 18 (1 + 8 = 9)
| |
| * 3 × 9 = 27 (2 + 7 = 9)
| |
| * 9 × 9 = 81 (8 + 1 = 9)
| |
| * 121 × 9 = 1089 (1 + 0 + 8 + 9 = 18; 1 + 8 = 9)
| |
| * 234 × 9 = 2106 (2 + 1 + 0 + 6 = 9)
| |
| * 578329 × 9 = 5204961 (5 + 2 + 0 + 4 + 9 + 6 + 1 = 27; 2 + 7 = 9)
| |
| * 482729235601 × 9 = 4344563120409 (4 + 3 + 4 + 4 + 5 + 6 + 3 + 1 + 2 + 0 + 4 + 0 + 9 = 45; 4 + 5 = 9)
| |
| There are other interesting patterns involving multiples of nine:
| |
| * 12345679 x 9 = 111111111
| |
| * 12345679 x 18 = 222222222
| |
| * 12345679 x 81 = 999999999
| |
| This works for all the multiples of 9.
| |
| ''n'' = [[3 (number)|3]] is the only other ''n'' > 1 such that a number is divisible by ''n'' if and only if its digital root is ''n''. In [[positional notation|base N]], the [[divisor]]s of N − 1 have this property. Another consequence of 9 being 10 − 1, is that it is also a [[Kaprekar number]].
| |
| | |
| The difference between a base-10 positive integer and the sum of its digits is a whole multiple of nine. Examples:
| |
| * The sum of the digits of 41 is 5, and 41-5 = 36. The digital root of 36 is 3+6 = 9, which, as explained above, demonstrates that it is divisible by nine.
| |
| * The sum of the digits of 35967930 is 3+5+9+6+7+9+3+0 = 42, and 35967930-42 = 35967888. The digital root of 35967888 is 3+5+9+6+7+8+8+8 = 54, 5+4 = 9.
| |
| | |
| Subtracting two base-10 positive integers that are transpositions of each other yields a number that is a whole multiple of nine. Examples:
| |
| * 41 - 14 = 27 (2 + 7 = 9)
| |
| * 36957930 - 35967930 = 990000, a multiple of nine.
| |
| This works regardless of the number of digits that are transposed. For example, the largest transposition of 35967930 is 99765330 (all digits in descending order) and its smallest transposition is 03356799 (all digits in ascending order); subtracting pairs of these numbers produces:
| |
| * 99765330 - 35967930 = 63797400; 6+3+7+9+7+4+0+0 = 36; 3+6 = 9.
| |
| * 99765330 - 03356799 = 96408531; 9+6+4+0+8+5+3+1 = 36; 3+6 = 9.
| |
| * 35967930 - 03356799 = 32611131; 3+2+6+1+1+1+3+1 = 18; 1+8 = 9.

| |
| | |
| Every prime in a [[Cunningham chain]] of the first kind with a length of 4 or greater is congruent to 9 mod 10 (the only exception being the chain 2, 5, 11, 23, 47).
| |
| | |
| Six recurring nines appear in the decimal places 762 through 767 of [[pi]]. This is known as the [[Feynman point]].

| If an odd [[perfect number]] is of the form 36''k'' + 9, it has at least nine distinct prime factors.<ref>Eyob Delele Yirdaw, "[http://arxiv.org/abs/0804.0152v1 Proving Touchard's Theorem from Euler's Form]" ArXiv preprint.</ref>
| |
| | |
| If you divide a number by the amount of 9s corresponding to its number of digits, the number is turned into a [[repeating decimal]]. (e.g. 274/999 = 0.274274274274...)

| ===Probability===
| |
| In [[probability]], the '''nine''' is a [[logarithmic measure]] of probability of an event, defined as the negative of the base-[[10 (number)|10]] [[logarithm]] of the probability of the event's [[Probability axioms|complement]].
| |
| For example, an event that is 99% likely to occur has an unlikelihood of 1% or 0.01, which amounts to −log<sub>10</sub> 0.01 = 2 nines of probability.
| |
| [[0 (number)|Zero]] probability gives zero nines (−log<sub>10</sub> 1 = 0). A 100% probability is considered to be impossible in most circumstances: that results in [[infinite improbability]]. The effectivity of processes and the [[availability]] of [[systems]] can be expressed (as a rule of thumb, not explicitly) as a series of "nines". For example, [[5 nines|"five nines" (99.999%)]] availability implies a total [[downtime]] of no more than five minutes per year - typically a very high degree of [[:wikt:reliability|reliability]]; but never 100%.

The number 9 is currently honoured for Hall of Famers [[Ted Kennedy (ice hockey)|Ted Kennedy]] and [[Charlie Conacher]].
| |
| ** The first NHL incarnation of the [[Winnipeg Jets (1972–96)|Winnipeg Jets]], also for Hull.

The Coyotes briefly took the number out of retirement for Hull's son [[Brett Hull]], also a Hall of Famer, in 2005–06 until the younger Hull retired five games into that season. The current [[Winnipeg Jets]] have yet to officially retire any numbers, but [[Evander Kane]] received Bobby Hull's blessing to wear the number.
