In an given AP,a=7,d13=35,find d1and s13 |
| Answer» Here, a = 7a13 = 35an\xa0= a + (n - 1)d{tex} \\Rightarrow {/tex}\xa0a13 = a + (13 - 1)d{tex} \\Rightarrow {/tex}\xa0a13 = a + 12d{tex} \\Rightarrow {/tex}\xa035 = 7 + 12d{tex} \\Rightarrow {/tex}\xa012d = 35 - 7{tex} \\Rightarrow {/tex}\xa012d = 28{tex} \\Rightarrow d = \\frac{{28}}{{12}}{/tex}{tex} \\Rightarrow d = \\frac{7}{3}{/tex}Again, we know that{tex}{S_n} = \\frac{n}{2}\\left[ {2a + (n - 1)d} \\right]{/tex}{tex} \\Rightarrow {S_{13}} = \\frac{{13}}{2}\\left[ {2a + (13 - 1)d} \\right]{/tex}{tex} \\Rightarrow {S_{13}} = \\frac{{13}}{2}\\left[ {2a + 12d} \\right]{/tex}{tex}={S_{13}} = \\frac{{13}}{2}\\left[ {2(7) + 12\\left( {\\frac{7}{3}} \\right)} \\right]{/tex}{tex} \\Rightarrow {S_{13}} = \\frac{{13}}{2}(14 + 28){/tex}{tex} \\Rightarrow {S_{13}} = \\frac{{13}}{2}(42){/tex}{tex} \\Rightarrow {S_{13}} = (13)(21){/tex}{tex} \\Rightarrow {S_{13}} = 273{/tex} | |

Use Euclid\'s algorithm to find hcf of 1190 and 1445.express the hcf in the form 1190m+1445n. |
| Answer» Here we have to find HCF of 1190 and 1445 and express the HCF in the form 1190m + 1445n.1445 = 1190 ×\xa01 + 2551190 = 255 ×\xa04 + 170255 = 170 ×\xa01 + 85170 = 85 ×\xa02 + 0So, now the remainder is 0, then HCF is 85Now,85 = 255 - 170= (1445 - 1190) - (1190 - 255 ×\xa04)= 1445 - 1190 - 1190 + 255 ×\xa04= 1445 - 1190 ×\xa02 + (1445 - 1190) ×\xa04= 1445 - 1190 ×\xa02 + 1445 × 4 - 1190 ×\xa04= 1445 ×\xa05 - 1190 ×\xa06= 1190 ×\xa0(- 6) + 1445 ×\xa05= 1190m + 1445n , where m = - 6 and n = 5 | |

Solve (x-5)(x-6)=25÷24×24 |
| Answer» According to the question,{tex}(x - 5)(x - 6) = \\frac{{25}}{{{{\\left( {24} \\right)}^2}}}{/tex}{tex}\\Rightarrow x(x - 6) - 5(x - 6) = \\frac{{25}}{{{{(24)}^2}}}{/tex}{tex}\\Rightarrow {x^2} - 6x - 5x + 30 - \\frac{{25}}{{{{(24)}^2}}} = 0{/tex}{tex}\\Rightarrow {x^2} - 11x + 30 - \\frac{{25}}{{{{(24)}^2}}} = 0{/tex}{tex}\\Rightarrow {x^2} - 11x + \\frac{{30 \\times {{24}^2} - 25}}{{{{(24)}^2}}} = 0{/tex}{tex} \\Rightarrow {x^2} - 11x + \\frac{{30 \\times 576 - 25}}{{{{(24)}^2}}} = 0{/tex}{tex} \\Rightarrow {x^2} - 11x + \\frac{{17280 - 25}}{{{{(24)}^2}}} = 0{/tex}{tex}\\Rightarrow {x^2} - \\frac{{264x}}{{24}} + \\frac{{145}}{{24}} \\times \\frac{{119}}{{24}} = 0{/tex}{tex}\\Rightarrow {x^2} - \\left( {\\frac{{145}}{{24}} + \\frac{{119}}{{24}}} \\right)x + \\frac{{145}}{{24}} \\times \\frac{{119}}{{24}} = 0{/tex}{tex}\\Rightarrow {x^2} - \\frac{{145}}{{24}}x - \\frac{{119}}{{24}}x + \\frac{{145}}{{24}} \\times \\frac{{119}}{{24}} = 0{/tex}{tex}\\Rightarrow x\\left( {x - \\frac{{145}}{{24}}} \\right) - \\frac{{119}}{{24}}\\left( {x - \\frac{{145}}{{24}}} \\right) = 0{/tex}{tex}\\Rightarrow \\left( {x - \\frac{{145}}{{24}}} \\right)\\left( {x - \\frac{{119}}{{24}}} \\right) = 0{/tex}{tex}\\Rightarrow x - \\frac{{145}}{{24}} = 0{/tex} or {tex}x - \\frac{{119}}{{24}} = 0{/tex}{tex}\\Rightarrow x = \\frac{{145}}{{24}}{/tex} or {tex}x = \\frac{{119}}{{24}}{/tex} | |
