Given ∆ABC-∆PQR if AB/PQ =1/3 then find arear ∆ABC/area∆PQR |
| Answer» Given:\xa0{tex}\\Delta ABC \\sim \\Delta PQR{/tex}Since we know that ,the ratio of area of two similar triangles is equal to the square of ratio of their corresponding sides. Thus,{tex}\\frac{\\text { ar } \\triangle \\mathrm{ABC}}{\\text { ar } \\triangle \\mathrm{PQR}}{/tex}\xa0=\xa0{tex}\\frac{\\mathrm{AB}^{2}}{\\mathrm{PQ}^{2}}{/tex}\xa0=\xa0{tex}\\left(\\frac{1}{3}\\right)^{2}{/tex}\xa0=\xa0{tex}\\frac{1}{9}{/tex} | |

Prove root 5 is irrational |
| Answer» Let us assume that root 5 is rational.Let p and q be real number and co primes.Now, let p and q have another factor other than 1.Now, root 5 = p/qRoot 5q= p.....................(i)(Squaring both side)Root 5q whole square = p square5q square = p squareP square is divisible by 5..Hence, p is divisible by 5..Let us take p = 5k where k is an integerFrom eq (i)...P = root 5q5k = root 5 q(Squaring both side)25k square = 5q5k square = q squareSo, q square is divisible by 5 Hence, q is divisible by 5Hence, p and q have other factors other than 1, that is 5...Hence our assumption is wrong that p and q are co primes...This contradicts the fact that root 5 is irrational.So, root 5 is irrational..This sum is looking so lengthy but its actually not..??????? | |

Show that the square of any possitive integer cannot be of the form of 5q+2 or 5q+3 for any integer |
| Answer» Let n be any positive integer. Applying Euclids division lemma with divisor = 5, we get{tex}\\style{font-family:Arial}{\\begin{array}{l}n=5q+1,5q+2,5q+3\\;and\\;5q+4\\;\\\\\\end{array}}{/tex}Now (5q)2 = 25q2 = 5m, where m = 5q2, which is an integer;{tex}\\style{font-family:Arial}{\\begin{array}{l}(5q\\;+\\;1)^{\\;2}\\;=\\;25q^2\\;+\\;10q\\;+\\;1\\;=\\;5(5q^2\\;+\\;2q)\\;+\\;1\\;=\\;5m\\;+\\;1\\\\where\\;m\\;=\\;5q^2\\;+\\;2q,\\;which\\;is\\;an\\;integer;\\\\\\;(5q\\;+\\;2)^2\\;=\\;25q^2\\;+\\;20q\\;+\\;4\\;=\\;5(5q^2\\;+\\;4q)\\;+\\;4\\;=\\;5m\\;+\\;4,\\\\\\;where\\;m\\;=\\;5q^2\\;+\\;4q,\\;which\\;is\\;an\\;integer;\\\\\\;(5q\\;+\\;3)^{\\;2}\\;=\\;25q^2\\;+\\;30q\\;+\\;9\\;=\\;5(5q^2\\;+\\;6q+\\;1)\\;+\\;4\\;=\\;5m\\;+\\;4,\\\\\\;where\\;m\\;=\\;5q^2\\;+\\;6q\\;+\\;1,\\;which\\;is\\;an\\;integer;\\\\\\;(5q\\;+\\;4)^2\\;=\\;25q^2\\;+\\;40q\\;+\\;16\\;=\\;5(5q^2\\;+\\;8q\\;+\\;3)\\;+\\;1\\;=\\;5m\\;+\\;1,\\;\\\\where\\;m\\;=\\;5q^2\\;+\\;8q\\;+\\;3,\\;which\\;is\\;an\\;integer\\\\\\end{array}}{/tex}Thus, the square of any positive integer is of the form 5m, 5m + 1 or 5m + 4 for some integer m.It follows that the square of any positive integer cannot be of the form 5m + 2 or 5m + 3 for some integer m. | |
