In an AP:1 given a =5, d = 3, a = 50, find n and S22 what​

Answer»

Answer:

N=16 and S(22)=374

a(n)=50

a=5

d=3

a(n)=a+(n-1)d

50=5+(n-1)3

45=(n-1)3

n-1=45/3=15

n=15+1=16

S(n)=n/2[2a+(n-1)d]

S(22)=11[10+(21)3]=11[10+24]=11(34)=374

If 4 cos2 x° - 1 = 0 and 0 < x < 90, find(i) x(ii) sin2 xº + cos2 x® (iii) cos2 x° - sin2 xº.​

Answer»

1. 4 cos²(2x) - 3 = 0

cos²(2x) = 3/4

cos(2x) = ± √(3/4) = ±√3/2

Remember, cos(Θ) = ±√3/2 when Θ = 30°, 150°

So, 2x = 30° and 2x = 150°

x = 15° and x = 75°

both meet the CRITERION 0 ≤ x ≤ 90

2. 2 sin²(x) - sin(x) = 0

sin(x) * (2 sin(x) - 1) = 0

So EITHER sin(x) = 0 or 2SIN(x) - 1 = 0

sin(x) = 0 when x = 0° or 180°

2sin(x) - 1 = 0 --> sin(x) =1/2

sin(x) = 1/2 when x = 30° or x = 150°

To satisfy the criterion 0 ≤ x ≤ 90,

x = 0° or 30°

= (ksinB - ksinC/k sinA )cos A/2

= {[2 cos B+C/2 Sin B-C/2]/ Sin A} cos A/2

Prove root3 is irrational​

Answer»

\huge \purple {Answer}

Let √3 is a RATIONAL number.

Therefore, It can be expressed in the FORM of p/q, where p and q are co-primes and q≠ 0.

⇒ √3 = \frac {p}{q}

By squaring both sides

⇒ 3 = \frac {p²}{q²}

⇒ 3q² = p² -(i)

This means that 3 divides p². This means that 3 divides p because each factor should appear two times for the SQUARE to exist.

So, we have p = 3r, where r is some integer.

⇒ p² = 9r² -(ii)

from equation (i) and (ii)

⇒ 3q² = 9r²

⇒ q² = 3r²

Where q² is multiply of 3 and also q is MULTIPLE of 3.

Then p, q have a common factor of 3. This runs contrary to their being co-primes. CONSEQUENTLY, \frac {p}{q} is not a rational number. This demonstrates that √3 is an irrational number.

\boxed {Hence, \: proved}
