What is euclid division of lemma and algorithm |
|
Answer» According to Euclid’s Division Lemma if we have two positive integers a and b, then there exist unique integers q and r which satisfies the condition a = bq + r where 0 ≤ r ≤ b.The basis of the Euclidean division algorithm is Euclid’s division lemma. To calculate the Highest Common Factor (HCF) of two positive integers a and b we use Euclid’s division algorithm. HCF is the largest number which exactly divides two or more positive integers. By exactly we mean that on dividing both the integers a and b the remainder is zero. I don\'t know Nothing |

If A(1,2),B(-3,2)and C(3,-2) be the vertices of the triangle ABC, show that tanA=2. |
| Answer» The vertices of the triangle ΔABC are A (1, 2), B (- 3, 2) and C (3, - 2). The sides of the triangle are AB, BC, CA and we have to find the tangent ratio of the angle A.The slope of the line AB ism₁ = (2 - 2) / (- 3 - 1)= 0 andthat of the line CA ism₂ = (2 + 2) / (1 - 3)= - 2Then the angle A is determined fromtanA = (m₁ - m₂) / (1 + m₁m₂)= (0 + 2) / (1 + 0)= 2Hence tanA = 2 | |

Prove that 5/√7 is irrational |
| Answer» Let 5/√7 is rational numberThen,5/√7=xOr 5/x =√7......(1) Then 1/x (x is not equal to 0) is a rational number , because 1and x are quotient which are rational numbers Since from (1), rational number = irrational number , which is impossible Hence 5/√7 is not a rational number ,it is irrational number. | |

Solve the following using equation by sublimation method 1x-3y-11=0 and 5x+y-7=0 |
|
Answer» 1x - 3y= 11 .......... (i)5x+y= 7....... (ii)Multiply equation (ii) by 315x + 3y = 21 ........... (iii)Adding (i) and (iii), we get16x = 32x = 32/16 = 2Put x = 2 in (i), we gwtx - 3y = 112 - 3y = 11-3y = 9y = -3 x=2. y=-3 |
