If three unequal positive real numbers satisfying b^2=ac and b – c, c – a, a – b are in H.P. then the value of a + b + c is independent of |
|
Answer» Given : If THREE unequal positive real numbers satisfying b² = ac and b – c, c – a, a – b are in H.P . To find : The VALUE of (a + b + c) is independent of solution : we have , b – c, c – a, a – b are in H.P . so, 1/(b - c) , 1/(c - a) and 1/(a - b) are in A.P ⇒1/(c - a) - 1/(b - c) = 1/(a - b) - 1/(c - a) ⇒2/(c - a) = 1/(b - c) + 1/(a - b) ⇒2/(c - a) = [(a - b) + (b - c)]/(b - c)(a - b) ⇒2/(c - a) = (a - c)/(b - c)(a - b) ⇒2(b - c)(a - b) = -(a - c)² ⇒2[ab - b² - ac + bc ] = - [a² + c² - 2ac ] ⇒2ab - 2b² - 2ac + 2bc = - a² - c² + 2ac ⇒a² + c² + 2ab - 2b² - 4AC + 2bc = 0 ⇒a² + b² + c² + 2ab + 2bc + 2ca - 6ca - 3b² = 0 ⇒(a + b + c)² - 6ca - 3b² = 0 ⇒(a + b + c)² - 6b² - 3b² = 0 [ as given b² = ca] ⇒(a + b + c)² = 9b² ⇒(a + b + c) = 3b Hence the value of (a + b + c) is independent of a and c. also read similar QUESTIONS : Three unequal positive numbers a, b, c are in gp then prove that a + c >2b If a, b, care in H.P., then value of c/a+ b-c/b-a +ab+bc/ac (C) 3 (D)4 (A) 1 (B) 2 |

Find 20 rational number Between -3 and-2 |
|
Answer» we know that between any two RATIONAL number there are infinite rational numbers. Step-by-step explanation: we may TAKE -3 as -30/10 and we may take -2 as -20/10. Now , Between -30/10 and -20/10 we have 10 rational numbers .so we had to find 10 more numbers . so , -30/10 ×11 /11 = (-330/110) and -20/10×11/11=(-220/110) hence, (-330/110) to (-220/110) we can write any number .

|
Answer» Answer: HOPE it help you mark me Step-by-step explanation: x = 01110 = 0×2^4 + 1×2^3 + 1×2^2 + 1×2^1 + 0×2^0 = 0 + 8 + 4 + 2 + 0 = 14 y = 11001 y = 1×2^4 + 1×2^3 + 0×2^2 + 0×2^1 + 1×2^0 = 16 + 8 + 0 + 0 + 1 = 25 so x + y = 14 + 25 = 39 39 now in binary 39 = 32 + 4 + 2 + 1 = 2^5 + 2^2 + 2^1 + 2^0 = 1 × 2^5 + 0 × 2^4 + 0 × 2^3 + 1 × 2^2 + 1 × 2^1 + 1 × 2^0 = 100111 |

For the following value of a, b and c verify that a x (b + c) = (a x b) + (a x c) Where a = 1/2 b = 2/3 c = 3/7 |
|
Answer» Answer: answer Step-by-step explanation: a x (b+c) = (a x b) + (a x c) AB + ac = ab + ac SUBSTITUTING the values we get, (1/2 x 2/3) + (1/2 x 3/7) = (1/2 x 2/3) + (1/2 x 3/7) 1/3 + 3/14 = 1/3 + 3/14 14/42 + 9/42 = 14/42 + 9/42 [ Since, LCM Of 3 and 14 is 42 ] 23/42 = 23/42 Hence, proved. |

If x – 3 and x - 1/3 are both factors of px^2+ 5x + r , then show that p = r. |
|
Answer» Now, if x-3 and x-1/3 are both factors to this expression , it means their division gives a VALUE of zero. Now lets USE x-3 >>> let x-3=0. >>> x=3 Now substitute x=3 into the expression >>>> Px^2+3x+r >>> P (3)^2 + 3(3) +r = 0 >>> 9p+ r + 9= 0 >>> 9p+r= -9 ……..(1) SIMULTANEOUS eqn Now use x-1/3. Let x-1/3=0 >>> x=1/3 Now substitute x=1/3 into the polynomial >>> P(1/3)^2+ 3(1/3) + r=0 >>> P(1/9)+ 1 +r =0 >>> P(1/9) + r= -1 >>> P + 9r = -9…(2) simultaneous eqn Subtract (1) from (2) >>> 9p+ r =-9 - P + 9r =-9 >>> 8p - 8r = 0 >>> 8p = 8r >>> p = r MARK me as brainliest |
