If cos ɵ = 3÷5 then what is the value of 6tan ɵ - 5cos ɵ ? |
|
Answer» Given : cosθ = 3/5 To find : the VALUE of (6tanθ - 5cosθ) SOLUTION : it is given that, cosθ = 3/5 = base/hypotenuse, so, base = 3 and hypotenuse = 5 from Pythagoras theorem, hypotenuse² = altitude² + base² ⇒5² = altitude² + 3² ⇒altitude = 4 now, tanθ = altitude/base = 4/3 now 6tanθ - 5cosθ = 6 × 4/3 - 5 × 3/5 = 8 - 3 = 5 Therefore the value of (6tanθ - 5cosθ) = 5. |

If x2+5x+6=0 and 2x2+ax+b=0 has both roots in common then the value of a+b is __ |
|
Answer» Answer: 22 Step-by-step explanation: ⇒ x^2 + ( 3 + 2 )x + 6 = 0 ⇒ x^2 + 3x + 2x + 6 = 0 ⇒ x( x + 3 ) + 2( x + 3 ) = 0 ⇒ ( x + 3 ) ( x + 2 ) = 0 ⇒ x = - 3 or - 2 Hence roots of x^2 + 5x + 6 = 0 are - 3 and - 2. It means roots of 2x^2 + AX + b = 0 also are also - 3 and - 2. Therefore, equation must satisfy the condition when x = - 3 and - 2. When, x = - 3 ⇒ 2x^2 + ax + b = 0 ⇒ 2( - 3 )^2 + a( - 3 ) + b = 0 ⇒ 2( 9 ) - 3a + b = 0 ⇒ 18 - 3a + b = 0 ⇒ b - 3a = - 18 ...( 1 ) When x = - 2 ⇒ 2( - 2 )^2 + a( - 2 ) + b = 0 ⇒ 2( 4 ) + - 2a + b = 0 ⇒ 8 - 2a + b = 0 ⇒ b - 2a = - 8 ...( 2 )
Subtracting ( 1 ) from ( 2 ) ⇒ b - 2a - ( b - 3a ) = - 8 - ( - 18 ) ⇒ b - 2a - b + 3a = - 8 + 18 ⇒ a = 10 Hence, b - 2a = - 8 b = - 8 + 2( 10 ) b = 20 - 8 b = 12 Therefore, ⇒ a + b = 10 + 12 = 22 |

Answer» Step-by-step EXPLANATION: F(x) = kx³ – 8x² + 5 ROOTS are α – β , α & α +β Sum of roots = – (-8)/k Sum of roots = α – β + α + α +β = 3α = 3α = 8/k = k = 8/3α or we can solve as below f(x) = (x – (α – β)(x – α)(x – (α +β)) = (x – α)(x² – x(α+β + α – β) + (α² – β²)) = (x – α)(x² – 2xα + (α² – β²)) = x³ – 2x²α + x(α² – β²) – αx² +2α²x – α³ + αβ² = x³ – 3αx² + x(3α² – β²) + αβ² – α³ = kx³ – 3αkx² + xk(3α² – β²) + k(αβ² – α³) comparing with kx³ – 8x² + 5 k(3α² – β²) = 0 => 3α² = β² k(αβ² – α³) = 5 =k(3α³ – α³) = 5 = k2α³ = 5 3αk = 8 => k = 8/3α (8/3α)2α³ = 5 => α² = 15/16 => α = √15 / 4 |

Answer» Answer: Step-by-step explanation: let A^3 = t => A = t^(1/3) PUTTING this value of root in x^2 -2x -1 =0 => t^(2/3) - 2t^(1/3) = 1 cubing on both sides, => t^2 - 8t - 6t=1 (by cubing IDENTITY) =>t^2 - 14t -1 = 0 so t= <14 + sqroot(196+4)>/2 or <14 -sqroot(196=+4)>/2 roots are 7 + 5root2 and 7-5root2 so EQUATION with such roots is x2 - 14x - 1 = 0 and from here A^3 + B^3 = 14 sum of roots and your answer |
