The sum of 1st 7 terms of an AP is 63 and sum of it\'s next 7 terms is 161.Find 28th term of an AP. |
| Answer» Let \'a\' be the first term and d be the common difference of the given AP. Then, using Sn= {tex}\\frac{n}{2}{/tex}{tex}\\cdot{/tex}[2a+(n-1)d], we get,\xa0S{tex}_7{/tex} = {tex}\\frac{7}{2}{/tex}(2a + 6d)Since sum of the first 7 terms of AP is 63 . Therefore,S{tex}_7{/tex}=63{tex}\\Rightarrow{/tex}7(a+3d)=63 {tex}{/tex}{tex}\\Rightarrow{/tex}a+3d=9.... (i)Since sum of the first 7 terms of an AP is 63 and the sum of its next 7 terms is 161.\xa0Therefore, the sum of first 14 terms = 63 +161 = 224.{tex}\\therefore{/tex}S14=224 {tex}\\Rightarrow{/tex}{tex}\\frac{{14}}{2}{/tex}(2a+13d)=224{tex}\\Rightarrow{/tex}7(2a+13d)=224{tex}\\Rightarrow{/tex}2a+13d=32....(ii)Multiplying (i) by 2 and subtracting the result from (ii), we get 7d = 14 {tex}\\Rightarrow{/tex}\xa0d = 2.Putting d = 2 in (i), we get a=9-6=3.Thus, a=3 and d=2.{tex}\\Rightarrow{/tex}28th term of this AP is given byT{tex}_{28}{/tex}=(a+27d)=(3+27{tex}\\times{/tex}2)=57.Hence, the 28th term of the given AP is 57. | |

prove that 3+√2is an irrational number |
|
Answer» Let us assume 3+√2is anrational numberSo,. 3+√2=a/b √2=a/b-3 √2=a-3b/bWe know that a/b is an rational number and 3 is also an rational number and when we add or subtract two rational number the result is also an rational.So,a-3b/b is an rational number.and,√2 is also a rational number. But, it contradicts the fact √2is irrational number.So, our assumption is false.Therefore,3+√2is an irrational number. AYUSH S SINGH Who are you ? Refer to ncert |

Find the value of a and b so that 8x+14-2x+ax+b is exactly divisible by 4x+,3x-2. |
| Answer» Let f(x) = 8x4 + 14x3 - 2x2 +7x - 8 and g(x) = 4x2 + 3x - 2We know that Dividend = Quotient {tex}\\times{/tex}\xa0Divisor + Remainderf(x) = g(x) {tex}\\times{/tex}\xa0q(x) + r(x){tex}\\Rightarrow{/tex}\xa0f(x) - r(x) = g(x) {tex}\\times{/tex}\xa0q(x){tex}\\Rightarrow{/tex} Dividend - Remainder = Quotient {tex}\\times{/tex}\xa0DivisorClearly, RHS of the above result is divisible by the divisor. Therefore, LHS is also divisible by the divisor. Thus, if we subtract remainder from the dividend, then it will be exactly divisible by the divisor.By\xa0long division method.Quotient = 2x2 + 2x - 1 and Remainder = 14x - 10Thus, if we subtract the remainder 14x - 10 from 8x4 + 14x3 - 2x2 + 7x - 8, it will be exactly divisible by 4x2 + 3x - 2. | |
