The sum ofthree numbers in AP are 3and their product is - 35.Find the numbers |
|
Answer» From the question it is given that, The sum of three NUMBERS in A.P. =3 Given, Their product =−35 Let us ASSUME the 3 numbers which are in A.P. are, a−d,a,a+d Now ADDING 3 numbers =
a−d+a+a+d=3 3a=3 a=3/3 a=1
From the question, product of 3 numbers is - 35 So, (a−d)×(a)×(a+d)=−35 (1−d)×(1)×(1+d)=−35 1 2 −d 2 =−35 d 2 =35+1 d 2 =36 d= 3
6 d=±6
Therefore, the numbers are (a−d)=1−6=−5 a=1 (a+d)=1+6=7
The numbers are (a−d)=1−(−6)=1+6=7 a=1 (a+d)=1+(−6)=1−6=−5 Therefore, the numbers −5,1,7,… and 7,1,−5,… are in A.P. |

Answer» Answer: Let the two chords be AB and CD. Let OE be the perpendicular drawn from the centre of the CIRCLE to the CHORD AB. Perpendicular drawn from the centre of the circle to the chord bisects the chord. Thus, AB = CD = 24 cm as chords of a circle equidistant from the centre are congruent. |

Prove root 3 is irrational numberLet us assume to the contrary that √3 is a rational number.It can be expressed in the form of p/qwhere p and q are co-primes and q≠ 0.⇒ √3 = p/q⇒ 3 = p2/q2 (Squaring on both the sides)⇒ 3q2 = p2………………………………..(1)It means that 3 divides p2 and also 3 divides p because each factor should appear two times for the square to exist.So we have p = 3rwhere r is some integer.⇒ p2 = 9r2………………………………..(2)from equation (1) and (2)⇒ 3q2 = 9r2⇒ q2 = 3r2We have two cases to consider now.Case ISuppose that r is even. Then r2 is even, and 3r2 is even which implies that q2 is even and so q is even, but this cannot happen. If both q and r are even then gcd(q,r)≥2 which is a contradiction.Case IINow suppose that r is odd. Then r2 is odd and 3r2 is odd which implies that q2 is odd and so q is odd. Since both q and r are odd, we can write q=2m−1 and r=2n−1 for some m,n∈N.Thereforeq2=3r2(2m−1)2=3(2n−1)24m2−4m+1=3(4n2−4n+1)4m2−4m+1=12n2−12n+34m2−4m=12n2−12n+22m2−2m=6n2−6n+12(m2−m)=2(3n2−3n)+1We note that the lefthand side of this equation is even, while the righthand side of this equation is odd, which is a contradiction.

Answer» Step-by-step explanation: prove root 3 is irrational number Let us assume to the contrary that √3 is a rational number. It can be expressed in the form of p/q where p and q are co-primes and q≠ 0. ⇒ √3 = p/q ⇒ 3 = p2/q2 (Squaring on both the sides) ⇒ 3q2 = p2………………………………..(1) It means that 3 divides p2 and also 3 divides p because each factor should appear two TIMES for the SQUARE to exist. So we have p = 3r where r is some integer. ⇒ p2 = 9r2………………………………..(2) from equation (1) and (2) ⇒ 3q2 = 9r2 ⇒ q2 = 3r2 We have two cases to consider now. Case I Suppose that r is even. Then r2 is even, and 3r2 is even which implies that q2 is even and so q is even, but this cannot happen. If both q and r are even then GCD(q,r)≥2 which is a contradiction. Case II Now suppose that r is odd. Then r2 is odd and 3r2 is odd which implies that q2 is odd and so q is odd. Since both q and r are odd, we can write q=2m−1 and r=2n−1 for some m,n∈N. Therefore q2=3r2 (2m−1)2=3(2n−1)2 4m2−4m+1=3(4n2−4n+1) 4m2−4m+1=12n2−12n+3 4m2−4m=12n2−12n+2 2m2−2m=6n2−6n+1 2(m2−m)=2(3n2−3n)+1 We NOTE that the lefthand SIDE of this equation is even, while the righthand side of this equation is odd, which is a contradiction. Therefore there exists no rational number r such that r2=3. Hence the root of 3 is an irrational number. Hence Proved |
