Triangle ABC smilir triangle PQR if AB by PQ=1BY 3 THEN FIND ar triangle ABC by ar triangle 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 that √6+√2 is irrational |
| Answer» Let take that 6 + √2 is a rational number.So we can write this number as6 + √2 = a/bHere a and b are two co-prime number and b is not equal to 0Subtract 6 both side we get√2 = a/b – 6√2 = (a-6b)/bHere a and b are an integer so (a-6b)/b is a rational number so √2 should be a rational number But √2 is an irrational number so it is contradictingHence result is 6 + √2 is a irrational number | |

Show that 18^n can never end with the digit zero |
| Answer» We have to find out that whether 18n can end with the digit 0 or 5 for any natural number nIf any number ends with the digit 0 then its\xa0factors must be in the form : 2m{tex} \\times {/tex}\xa05nIf\xa0any number ends with the digit 5 then its factors must be in form : 5m {tex} \\times {/tex}\xa03n or 5m{tex} \\times {/tex}\xa07n\xa0So for any number to end\xa0with the digit 0 or 5 its factors must be in form 5m {tex} \\times {/tex}\xa03n or 5m{tex} \\times {/tex}\xa07n\xa0\xa0or\xa02m{tex} \\times {/tex}\xa05n\xa0(where m and n are positive integers)Now, 18 = 2 × 9 = 2 × 3 × 3 = 2\xa0× 32So, 18n\xa0= (2\xa0× 32)n = 2n\xa0× (32)n= 2n\xa0× 32n18n is not in the form of 5m × 3n or 5m × 7n\xa0\xa0or\xa02m × 5n\xa0So, 18n cannot end with 0 or 5 for any natural number n. | |

Is remainder on dividing x cube + 2 X square + kx + 3 by x minus 3 is 21 find questions and K |
| Answer» Let p(x) ={tex} x^3 + 2x^2 + kx + 3{/tex}Now, x - 3 = 0\xa0{tex}\\Rightarrow{/tex}\xa0x = 3By the remainder theorem, we know that when p(x) is divided by (x - 3), the remainder is p(3).Now, p(3) = (3)3\xa0+ 2(3)2\xa0+ k(3) + 3= 27 + 2(9) + 3k + 3= 30 + 18 + 3k\xa0= 48 + 3kBut, remainder = 21\xa0{tex}\\Rightarrow{/tex}\xa048 + 3k = 21{tex}\\Rightarrow{/tex} 3k = 21 - 48{tex}\\Rightarrow{/tex}\xa03k = -27{tex}\\Rightarrow{/tex} k = {tex}\\frac{-27}3{/tex}{tex}\\Rightarrow{/tex} k = -9So, the value of k is -9. | |
