Answer» Given: $\sin B$ = $\dfrac{1}{2}$ We have to show that $3\cos B-4\cos^3 B=0.$ SOLUTION: ∴ $\sin B$ = $\dfrac{1}{2}=\dfrac{p}{h}$ Here, p = PERPENDICULAR = 1 and h = hypotaneous = 2 By PYTHAGORAS THEOREM, Base, b = $\sqrt{h^{2}-p^{2}}$ = $\sqrt{2^{2}-1^{2}}$ = $\sqrt{4-1}$ = $\sqrt{3}$ $\cos B$ = $\dfrac{b}{h}=\dfrac{\sqrt{3}}{2}$ L.H.S. = $3\cos B-4\cos^3 B$ = $3(\dfrac{\sqrt{3}}{2})-4(\dfrac{\sqrt{3}}{2})^3$ = $(\dfrac{3\sqrt{3}}{2})-4(\dfrac{3\sqrt{3}}{8})$ = $(\dfrac{3\sqrt{3}}{2})-(\dfrac{3\sqrt{3}}{2})$ = 0 = R.H.S., proved. Thus, if $\sin B$ = $\dfrac{1}{2}$ , then $3\cos B-4\cos^3 B=0$ , SHOWN.

Sin B = 1/2 . Show that 3CosB-4CosB3(cube)=0

Answer»

Given:

$\sin B$ = $\dfrac{1}{2}$

We have to show that $3\cos B-4\cos^3 B=0.$

SOLUTION:

∴ $\sin B$ = $\dfrac{1}{2}=\dfrac{p}{h}$

Here, p = PERPENDICULAR = 1 and h = hypotaneous = 2

By PYTHAGORAS THEOREM,

Base, b = $\sqrt{h^{2}-p^{2}}$

= $\sqrt{2^{2}-1^{2}}$

= $\sqrt{4-1}$

= $\sqrt{3}$

$\cos B$ = $\dfrac{b}{h}=\dfrac{\sqrt{3}}{2}$

L.H.S. = $3\cos B-4\cos^3 B$

= $3(\dfrac{\sqrt{3}}{2})-4(\dfrac{\sqrt{3}}{2})^3$

= $(\dfrac{3\sqrt{3}}{2})-4(\dfrac{3\sqrt{3}}{8})$

= $(\dfrac{3\sqrt{3}}{2})-(\dfrac{3\sqrt{3}}{2})$

= 0

= R.H.S., proved.

Thus, if $\sin B$ = $\dfrac{1}{2}$ , then $3\cos B-4\cos^3 B=0$ , SHOWN.

ANSWER:

RS 1297 and 66 PAISE

Step-by-step explanation:

GIVEN. P= 500. r= 10%

A= P(1+10/100)^10

= 500×(11/10)^10

= (5×100×11^5×11^5)/ (100×10^8)

= 5× 161051×161051 / 10^8

= 5× 16.1051×16.1051. (DIVIDED by10⁴ each)

= 5× 16.11× 16.11

Solve the following pair of linear equations by theelimination method.x+3/5y=-18/53/2x+2y=-5/2

Answer»

Answer:

x=−57/11 and y= 29/11

Step-by-step explanation:

first multiply it by 10...

10(x+3/5y=−18/5)

−3(3/2x+2y=−5/2)

Becomes:

10x+6y=−36

−9/2x−6y=15/2

Then...

Add these EQUATIONS to ELIMINATE y:

11/2

x=−57/2

Then SOLVE

x=−57/2

for x:11/2

x=

(Simplify both sides of the equation)

y+(3/5)−57/11+57/11

=−18/5+57/11

(Add 57/11 to both sides)

3/5

y=87/55

y(3/5)/3/5

=

87/55/3/5

(Divide both sides by 3/5)

y=29/11

In the figure, this theorem applies to ∠PKL and ∠KNL. ⇒∠PKL = ∠KNL .........(i) Since LN is the diameter, ∠LKN=90° (Angle in a semicircle) In ΔLKN , by Angle Sum Property, ∠L + ∠K + ∠N = 180° ∠N + 30° + 90° =180° ∠KNL =180° - 120° ∠PKL=60° [from (i)]

Can anyone provide proper explaination of the question with answer

Answer»

Answer:

Step-by-step explanation:

ACTUALLY, in this question, you need to USE something CALLED the 'ALTERNATE Segment Theorem'.

This theorem states that the angle formed by a chord and a tangent is equal to the angle subtended by the chord in the alternate segment (major to MINOR/ minor to major).

In the figure, this theorem applies to ∠PKL and ∠KNL.

⇒∠PKL = ∠KNL .........(i)

Since LN is the diameter,

∠LKN=90° (Angle in a semicircle)

In ΔLKN , by Angle Sum Property,

∠L + ∠K + ∠N = 180°

∠N + 30° + 90° =180°

∠KNL =180° - 120°

∠PKL=60° [from (i)]

Sin(-11pi/3)tan(35pi/6)sec(-7pi/3)/cot (3pi/4)cosec(7pi/4)cos(11π/6)

To Find : Value of

SIN(-11π/3) . tan( 35π/6 ) . sec( -7π/3 ) . cot( 3π/4 ) . cosec( 7π/4 ) . COS( 11π/6 )

Solution :

GIVEN terms is sin(-11π/3) . tan( 35π/6 ) . sec( -7π/3 ) . cot( 3π/4 ) . cosec( 7π/4 ) . cos( 11π/6 )

Now ,

•sin( -11π/3 ) = -sin( 11π/3 )

= -sin( 4π - π/3 ) = sin(π/3) = √3/2

•tan( 35π/6 ) = tan( 6π-π/6)

= -tan(π/6) = -(1/√3) = -1/√3

• sec ( -7π/3 ) = sec( 7π/3 )

= sec( 2π + π/3 ) = sec ( π/3 ) = 2

• cot ( 3π/4 ) = cot ( π-π/4 )

= -cot(π/4) = -1

• cosec ( 7π/4 ) = cosec ( 2π - π/4 )

= - cosec ( π/4 ) = -√2

• cos ( 11π/6 ) = cos ( 2π - π/6 )

= cos ( π/6 ) = √3/2

•Now ,

sin(-11π/3) . tan( 35π/6 ) . sec( -7π/3 ) .cot( 3π/4 ) . cosec( 7π/4 ) . cos( 11π/6 ) = (√3/2)×(-1/√3)×(2)×(-1)×

(-√2)×(√3/2) = -√3/√2

•Hence , value of TERM is -√3/√2

Answer»

$\green {\boxed{\red{\huge{\fbox{\mathfrak{Answers}}}}}}$

${\huge{\red{\underline{\textbf{ATQ}}}}}$

$\frac{3}{8} 2m \times {( \frac{3}{8}) }^{6} \times \frac{3}{8} = { \frac{3}{8} }{13}$

$\frac{3}{8} \times \frac{3}{8} \times {( \frac{3}{8} )}^{6} \times ( \frac{3}{8} ) ^{ - 1} = \frac{13}{2m}$

$( \frac{3}{8} ) {}^{1 + 6 + 1 - 1} = \frac{13}{2m}$

49.	Find sum of first 10 terms of an AP whose first term is minus 5 and third term is 5
Answer» Answer: SUM of first 10 TERMS = 175. Step By Step Explanation: Given: First term, a₁ = -5 Third term, a₃ = 5 To Find: Sum of first 10 terms. Now, firstly we will find common difference, We know that, => a₃ = a + 2d => 5 = -5 + 2d => 10 = 2d => d = 10/2 => d = 5 Hence, common difference = 5 Now, we will come calculate sum of first 10 terms. => Sn = n/2[2a + (n - 1)d] => S₁₀ = 10/2[-10 + (10 - 1)5] => S₁₀ = 5[-10 + 45] => S₁₀ = 5[35] => S₁₀ = 175 Hence, sum of first 10 terms = 175.

49.

Find sum of first 10 terms of an AP whose first term is minus 5 and third term is 5

Answer»

Answer:

SUM of first 10 TERMS = 175.

Step By Step Explanation:

Given:

First term, a₁ = -5
Third term, a₃ = 5

To Find:

Sum of first 10 terms.

Now, firstly we will find common difference,

We know that,

=> a₃ = a + 2d

=> 5 = -5 + 2d

=> 10 = 2d

=> d = 10/2

=> d = 5

Hence, common difference = 5

Now, we will come calculate sum of first 10 terms.

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

=> S₁₀ = 10/2[-10 + (10 - 1)5]

=> S₁₀ = 5[-10 + 45]

=> S₁₀ = 5[35]

=> S₁₀ = 175

Hence, sum of first 10 terms = 175.
