if the remainder on dividing the polynomials 2x ^4-kx^2+5x - 3k+3 by (x+2) is 4,then find the value of k. |
Answer» Question:
Given:
To find:
Solution:Here, p(x) = 2x⁴ - kx² + 5x - 3k + 3 Now, x + 2 = 0 => x = (-2) By using remainder theorem, p(-2) = 2(-2)⁴ - k(-2)² + 5(-2) - 3k+ 3 = 32 - 4k - 10 - 3k + 3 = 32 - 10 + 3 - 3k - 4k = 25 - 7k .......(I) So here we GET the remainder as 25 - 7k. But in the question it is given that remainder is 4, therefore both are equal. So, 25 - 7k = 4 ( Both are same remainder) => (-7k) = 4 - 25 => (-7k) = (-21) => 7k = 21 ( Negative signs got cancelled) => k = 21/7 => k = 3 Answer:

Alpha, beeta are zeroes of quadratic polynomial p(x) =x²-6x+k if alpha-beeta =2 then find value of k |
|
Answer» Answer: 8 Step-by-step explanation: Given : α, β are zeroes of the QUADRATIC polynomial x² - 6X + k. Comparing x² - 6x + k with ax² + bx + k we get
Sum of zeroes = α + β = - b/a = - ( - 6 ) / 1 = 6 Product of zeroes = αβ = c/a = k / 1 = k Given : α - β = 2 Using ( α - β )² + 4αβ = ( α + β )² we get ⇒ ( α - β )² + 4αβ = ( α + β )² ⇒ ( 2 )² + 4( k ) = ( 6 )² ⇒ 4 + 4k = 36 ⇒ 4k = 36 - 4 ⇒ 4k = 32 ⇒ k = 32 / 4 ⇒ k = 8 Therefore the value of k is 8. |

When a rocket is fired upward then the path of the rocket is Defined by which function |
Answer» MARK THIS AS THE BRAINLIEST ANSWER .. FOLLOW METhere are two forces acting on a rocket at the moment of lift-off: Thrust PUSHES the rocket upwards by pushing gases downwards in the opposite DIRECTION. Weight is the force DUE to gravity pulling the rocket downwards towards the centre of the Earth. Step-by-step explanation: The propulsion of all rockets, jet engines, deflating balloons, and even squids and octopuses is explained by the same PHYSICAL principle: Newton's third law of motion. Matter is forcefully ejected from a system, producing an equal and opposite reaction on what remains. Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space. In fact, rockets work more efficiently in space than in an atmosphere Hope this HELPS |
