Difference between lemma and algorithms |
|
Answer» Lemma is a proven statement used for proving another statement while algorithm is a series of well defined steps which gives a procedure for solving a type of a problem.Euclid\'s division lemma: For given any positive integers a and b there exist unique integers q and r satisfying a = bq + r, 0 ⤠r < b.Euclid\'s division algorithm is used for finding the Highest Common Factor of two numbers where in we apply the statement of Euclid\'s division lemma. Lemma is a proven statement but algorithm is a series of well defined steps which gives a procedure to solve out any problem. |

Define polynomial? |
|
Answer» An algebraic expression can have exponents that are\xa0rational numbers. However, a polynomial is an algebraic expression in which the exponent on any variable is a whole number.5x3+3x+1 is an example of a polynomial. It is an algebraic expression as wellTypes of polynomials based on the number of termsa) Monomial – A polynomial with just one term. Example – 2x, 6x2, 9xyb)\xa0Binomial – A polynomial with two terms. Example – 4x2+x, 5x+4a) Trinomial – A polynomial with three terms. Example – x2+3x+4\xa0 Expression in which power of variable is non-integral and non-negative |

| Answer» | |
| 32. |
If p and q are two coprime numbers write their LCM and HCF |
| Answer» Since, p and q are two co-prime numbersCo-primes means only common factor is 1.HCF is the highest common factor.So, HCF(p,q)=1To find LCM, we know thatProduct of two numbers = HCF × LCMp × q = 1 × LCMLCM = {tex}p\\times q{/tex} | |

Show that the points (1,7),(4,2),(-1,-1),(-4,4) are the vertices of a square? |
| Answer» Given points are (1,7),(4,2),(-1,-1),(-4,4)Let the points are A,B,C,D.Distance formula =\xa0√(x₂-x₁)²+(y₂-y₁)² AB =\xa0√(4-1)²+(2-7)² =\xa0√9+25 =\xa0√34 BC =\xa0√(-1-4)²+(-1-2)² =\xa0√25+9 = √34 CD =\xa0√(-4-(-1))²+(4-(-1))² =\xa0√9+25 = √34 DA =\xa0√(1-(-4))²+(7-4)² =\xa0√25+9 =\xa0√34\tWe know that the all sides of the square are equal. Here by the distance formula, we got the for sides equal So,from this we can say that these points are the vertices of a square. | |
