If p(x) = x cube + kx square + hx + 6 and x+1 and x-2 are factors of p(x) then find the value of H and K.

Answer»

<P>Answer:

$p(x) = {x}^{3} + k {x}^{2} + hx + 6$

Since (x+1) and (x-2) are factors of p(x).

p(-1) =p(2)=0 =>

${( - 1)}^{3} + k {( - 1)}^{2} + h( - 1) + 6 = 0$

And

${2}^{3} + k {(2)}^{2} + h(2) + 6 = 0$

-1+k-h+6 =0 => h-k =5...(1)and 4k+2h+14 =0=> h+2k = -7...(2). Multiply (1) by 2 and ADD (2) => 2h-2k+h+2k =10-7 => 3h=3 => h=1 and substitute the value of h as 1 in equation (1) => 1-k =5 => k =1-5 = -4. The values of h and k are -1 and 4. Hope it helps you.

Answer» Answer: 13/9 Step-by-step explanation: roots of eqn= -b +(or)- √b square - 4 ac/ 2A comparing eqn with ax^2+bx+c=0 a=1 b=8 c=6 so SUBSTITUTING values in above formula we get alpha=-4+√10 beta=-4-√10 on solving we get REQUIRED answer=13/9

47.

alpha and beta are the zeros of polynomial X square + 8 x + 6 form a polynomial whose zeroes are 1 by Alpha square + 1 by beta square

Answer»

Answer:

13/9

Step-by-step explanation:

roots of eqn= -b +(or)- √b square - 4 ac/ 2A

comparing eqn with ax^2+bx+c=0

a=1 b=8 c=6

so SUBSTITUTING values in above formula we get

alpha=-4+√10

beta=-4-√10

on solving we get

REQUIRED answer=13/9

Answer» Answer: Step-by-step explanation: Let No. of CURRENCY notes of Rs 10 = 2X No. of currency notes of Rs 20 = 5x No. of currency notes of Rs 10 = 30 - (2x+5x) = 30 - 7x Amount made by Rs 10 notes = 10 × 2x = 20x Amount made by Rs 20 notes = 20 × 5x = 100x Amount made by Rs 50 notes = 50 × (30 - 7x) = 1500 - 350x Total MONEY = 1040 ⇒ 20x + 100x + 1500 - 350x = 1040 ⇒ - 230x = - 460⇒ x = 2 Denominations: Rs 10 = 2 × 2 = 4 Rs 20 = 5 × 2 = 10 Rs 50 = (30 - 7 × 2) = 16 THANK YOU PLEASE FOLLOw ME MARK THIS QUESTION BRAINLIST

Manya has a total of Rs. 1040 as currency notes Indian nomination of rupees 10 ,20 and 50 the ratio of the number of rupees 10 notes and 20 notes is 2 : 5 if she has a total of 30 notes how many notes of each denomination she has ?

Answer»

Answer:

Step-by-step explanation:

Let

No. of CURRENCY notes of Rs 10 = 2X

No. of currency notes of Rs 20 = 5x

No. of currency notes of Rs 10 = 30 - (2x+5x) = 30 - 7x

Amount made by Rs 10 notes = 10 × 2x = 20x

Amount made by Rs 20 notes = 20 × 5x = 100x

Amount made by Rs 50 notes = 50 × (30 - 7x) = 1500 - 350x

Total MONEY = 1040

⇒ 20x + 100x + 1500 - 350x = 1040

⇒ - 230x = - 460⇒ x = 2

Denominations:

Rs 10 = 2 × 2 = 4

Rs 20 = 5 × 2 = 10

Rs 50 = (30 - 7 × 2) = 16
