Answer:

A language is context-free if it is generated by a CFG. For compactness, we write S → 0S1 | ε where the vertical bar means or. Let P be language of palindromes with alpha- bet {a,b}. One can determine a CFG for P by finding a recursive decomposition.

   Venice

   Kolonisasyon

Explanation:

Noong ika-15 siglo, ang dalawang bansang magkatunggali sa pagpapalaki ng kanilang mga nasasakupan ay ang Espanya at ang Portugal. Dahil sa pagnanais nilang makahanap ng panibagong mga teritoryong maaaring sakupin, nagkaroon ng kasunduan ang dalawang bansa sa pamamagitan ng Kasunduan ng Tordesillas na pinagtibay ni Pope Julius II noong 1494.

Sa ilalim ng kasunduang ito, lahat ng teritoryong nasa silangan ay mapupunta sa Portugal, habang ang lahat naman ng teritoryong nasa kanluran ay mapupunta sa Espanya.

Nais din ng dalawang bansang ito na makahanap ng magandang rutang pangkalakal ng mga pampalasa mula sa Moluccas, upang kalabanin ang mayamang estado ng Venice na siyang nangunguna sa kalakalan noong ika-15 siglo.

Hay cuatro tipos básicos de tejido: tejido conectivo, tejido epitelial, tejido muscular y tejido nervioso. El tejido conectivo sostiene y une otros tejidos como el óseo, el sanguíneo y el linfático. El tejido epitelial sirve de cobertura; entre éstos se encuentran la piel y el revestimiento de varios conductos en el interior del cuerpo. El tejido muscular consta de músculos estriados o voluntarios que mueven el esqueleto y de músculo liso, tal como el que rodea al estómago. El tejido nervioso está formado por células nerviosas o neuronas y sirve para llevar "mensajes" hacia y desde varias partes del cuerpo.

How many permutations are there of the letters in the word polyunsaturated.

Answers

Answer:

3.27e11

Explanation:

[tex]\frac{15!}{2! 2!}[/tex]

15! = 15 * 14 * 13 * 12 * 11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 1.31e12

If there are no letters with multiple occurences, the answer would be around 1.31e12. However, since we have 2 "a" and 2 "t", we need to divide by 2! and 2! to prevent double-counting some permutations.
