b

root (x+1) -root(x-1)=root(4x-1)

squaring both sides, we get

x+1+x-1-2root(x^2-1)=4x-1

2x-2root(x^2-1)=4x-1

-2x+1=2root(x^2-1)

squaring again both sides

4x^2+1-4x=4(x^2-1)

4x^2+1-4x=4x^2-4

5=4x

x= 5/4it is having only one solution show option B is the right answer thank you so much

thanq😊😊

Rank will be 4 for this

Eliminate elements in the 1st column under the 1st element

2)Swap the 2nd and the 4th rows

Eliminate elements in the 3rd column under the 3rd element

4)Calculate the number of linearly independent rows

sin - cos = 0sin = costan = 1 so = 45°sosin⁴ + cos⁴ = (1/√2)⁴ + (1/√2)⁴= 1/4 + 1/4 = 2/4 = 1/2

sin 15 = sin(45 - 30)= sin45 cos30 - cos45 sin30= ½√2(½√3) - ½√2(½)= ¼(√6 - √2)maka3 sin15 - 4 sin³15 = 3(¼(√6 - √2)) - 4(¼(√6 - √2))³= ¾(√3√2 - √2) - (1/16)(√3√2 - √2)³= (√3 - 1)¾√2 - (3√3 - 5)¼√2

Please solve

204 + 110 =314; 360-314=46

x^3+1/x^3=110

(x+1/x)^3=x^3+1/x^3+3(x+1/x)

(x+1/x)^3=110+3 (x+1/x)

Let(x+1/x)=a eq … 1 So,

a^3=110+3a

a^3-3a-110=0

P (a)=a^3-3a-110

PUT a=5

P (5)=(5)^3-3 (5)-110=125-15-110

125-125=0

P (5)=0

1st factor =(a-5)

Write (a-5) three times and put the value according to polynomial

a^2(a-5)+5a(a-5)+22(a-5)

(a-5)(a^2+5a+22)

If (a-5)=0 or (a^2+5a+22)=0

(a-5)=>x+1/x-5=0 from eq1

For the 6th term, put n=6 in the given sequence an=(n-1)(2-n)(3+n)=(6-1)(2-6)(3+6)=5*(-4)*9=-180

8 is the Answer

(-37)×0-(-8)=0-(-8)=0+8=8 is your answer plz like thanks

sinA - cosA = 0

⇒ sinA = cosA

⇒ sinA/cosA = 1

⇒ tanA = 1

⇒ tanA = tan45°

⇒ A = 45°

∴ sin⁴A + cos⁴A

= sin⁴45° + cos⁴45°

= (1/√2)⁴ + (1/√2)⁴

= 1/4 + 1/4

= 2/4

= 1/2

A+B= 90A= 90-BcosA= cos(90-b) = sinb

No, Because acuteangle measures less then 90 degrees and more then 0 degrees.

so if we take the biggest acute angle and it with itself it will be less then 180 degrees. Eg:-89 + 89 = 178

let the digits be x and y. x - y = 3; x = y + 3(10x + y) + (10y + x) = 7711x + 11y = 77x + y = 7y + 3 + y = 72y = 4y = 2x = 2 + 3 = 5original no. is 52

supplement angles addition is 180so x=1/3(180-x)3x=180-xso 4x=180so x=45so.angles are 45 and 135

Think you so much

x + 2/3x =180 5/3x= 180 x=180×3/5x= 108 . so the other angle is 2×108/3 = 72

1) sum of supplementary angles is = 180° so , let the angle be x => supplementary angle is. 180-x

also , its complementary angle is 90-x now , according to the question..180-x = 4(90-x) => 4x-x = 360-180 => 3x = 180° so, x = 180/3 = 60°

2) sum of complementary angle is 90°so, let the bigger angle be xnow its complimentary angle is 90-x ,

and also its supplementary angle is 180-x

now according to the question 180-x = 3(90-x) => 3x-x = 270-180 => 2x = 90 => x = 45°
