(1+tanx)^2+(1+cotx)^2​

Answer»

(1-tanx )^2 + (1-cotx )^2

= 1-2tanx+tan^2x+1-2cotx+cot^2x

= (1+tan^2x)+(1+cot^2x)-2(tanx+cotx)

We KNOW that;

1+tan^2x = sec^2x

1+cot^2x = cosec^2x

sin^2x+cos^2x = 1

(tanx+cotx)

= sinx/cosx+cosx/sinx

= (sin^2x+cos^2x)/(SINXCOSX)

= 1/(sinxcosx)

= secxcosecx

(1-tanx )^2 + (1-cotx )^2

= (1+tan^2x)+(1+cot^2x)-2(tanx+cotx)

= sec^2x-2secxcosecx+cosec^2x

(secx-cosecx)^2 = sec^2x-2secxcosecx+cosec^2x

(1-tanx )^2 + (1-cotx )^2

= (1+tan^2x)+(1+cot^2x)-2(tanx+cotx)

= sec^2x-2secxcosecx+cosec^2x

= (secx-cosecx)^2

Find the value of k for which the Givenequation has real and equal oroots .1)2x² - 10x+k=0 2) kx²5x+K=03) x^2+ k(4x+k-1) +2=04) x^2-2k( 1+3k] +7 (3+2k),,,5)kx(x-3)+9=0 ..6)kx(x- 2√5)+10=0​

Answer»

Step-by-step EXPLANATION:

solution:>

for equal and REAL ROOTS => b²= 4ac

(1) (-10)²= = 8k => k= 100/8= 12.5

(2) (±5)²= 4k² => k²= 25/4=> k= ±5/2

(3) (4k)²= k²-k+2 => 15k²+k-2=0

15k²+6k-5k-2=0

3k(5 k+2) - 1( 5k+2)=0

(5k+2) ( 3k-1)= 0=> k = - 2/5 and k= 1/3

(4) here b=0

4ac= 4[ -2k(1+3k)+7(3+2k)

=> 0 = 4[ -2k-6k²+21+14k]

=>. 4[ -6k²+12k+21]= 0

=> 2k²-4k-7= 0 dividing by - 12

k= [ 4±√(16-4×2×-7)] / 4

= ( 4± √-40)/4=> k= 1± (√-10)/2

(5) b²= (-3k)²= 9k²

4ac= 4×k×9= 36k

=> 9k²= 36k => 9k( k-4)=0

=> k=0 or k=4

(6) b²= (-2√5)²= 20,. 4ac= 4×k×10= 40K

=>. 20= 40k=>. k= 1/2

In an election of housing society, there are 30 voters. Each of them gives the vote. Three people X, Y and Z are standing for the post of secretary. If Mr. X got 2/5 of the total votes and Mr. Z got 1/3 of the total votes, then find the number of votes which Mr. Y got

Answer»

Answer:

8

Step-by-step explanation:

Number of votes of X = 2/5×30 = 12

Number of votes of Z = 1/3×30 = 10

Number of votes of Y = Total votes - [number of votes of X + Number of votes of Z ]

= 30 - [12 + 10]

= 8

Hence Y GOT 8 votes.

out of 1000 student 658 failed in aggregate ,166 in aggregate and in group1 434 in aggregate and in group2 372 in group1 590 in group 2 and 126 in both the groups. how many failed in aggregate but not in group 2? a)106 b)224 c)206 d) 464​

Answer»

Step-by-step EXPLANATION:

Given out of 1000 student 658 failed in aggregate ,166 in aggregate and in group 1 434 in aggregate and in group 2 372 in group 1  590 in group 2 and 126 in both the groups. how many failed in aggregate but not in group 2?

  • Let A, B and C be THREE sets.
  • So NUMBER of elements of A n(A) = 658
  • So number of elements of B n(B) = 590
  • So number of elements of C n(C ) = 372
  • Now n(A Ո B) = 434
  • So n (B Ո C) = 126
  • So n (C Ո A) = 166
  • So n (A U B U C) = 1000
  • n (A U B U C)  = n(A) + n(B) + n(C) – n (A Ո B) – n (B Ո C) – n (C Ո A) +  n (A Ո B Ո C)
  •          1000 = 658 + 590 + 372 – 434 – 126 – 166 + n (A Ո B Ո C)
  •          1000 = 894 + n (A Ո B Ո C)
  •              1000 - 894 = n (A Ո B Ո C)
  •         Or n (A Ո B Ո C) = 106
