9.

I Know The Answer (c). Plz explain It..

Answer»

Step-by-step explanation:

tan θ + sin θ = x

tan θ - sin θ = y

from the above two EQUATIONS, we get

=> 2 sin θ = x - y

sin θ = (x - y)/2 [ we will substitute this value later]

also, in the above two equations TAKING tan θ as COMMON we get,

tan θ (1 + cos θ) = x

tan θ (1 - cos θ) = y

dividing the above equations,

=> (1 + cos θ)/(1 - cos θ) = x/y

y + y cos θ = x - x cos θ

x - y = y cos θ + x cos θ

cos θ (x + y) = x - y

cos θ = $\frac{x-y}{x+y}$

squaring on both SIDES,

cos² θ = $(\frac{x-y}{x+y})^{2}$ [ sin²θ + cos²θ = 1]

1 - sin²θ = $(\frac{x-y}{x+y})^{2}$

$1-(\frac{x-y}{2})^{2} = \frac{(x-y)^{2}}{(x+y)^{2}}\\\\ 1-\frac{(x-y)^{2}}{4} =\frac{(x-y)^{2}}{(x+y)^{2}} \\\\ (x+y)^{2} - \frac{(x-y)^{2} (x+y)^{2}}{4} =(x-y)^{2} \\\\ (x+y)^{2} - (x-y)^{2}=\frac{(x^{2}-y^{2})^{2}}{4} \\\\4xy = \frac{(x^{2}-y^{2})^{2}}{4} \\\\x^{2}-y^{2} = \sqrt{16xy} \\\\x^{2}-y^{2} = 4\sqrt{xy} \\\\\\\ HOPE \ YOU \ GOT \ IT! \\\\\ THANKS$

Substitute this in (1). The result is: ${2+\sqrt{3} }+\frac{1}{2+\sqrt{3} }$ Rationalise $\frac{1}{2+\sqrt{3} }$ . $2+\sqrt{3} +\frac{1}{2+\sqrt{3}}\frac{2-\sqrt{3} }{2-\sqrt{3} }$ $2+\sqrt{3} +\frac{2-\sqrt{3} }{(2+\sqrt{3)(2-\sqrt{3})}}$ ................(2)* We know that (a+B)(a-b)=a²-b² (2+√3)(2-√3)⇒2²-(√3)³⇒4-3⇒1.

12.

Solve questions early dear friendso

Answer»

Answer:

$x=\sqrt[3]{<klux>2</klux>+\sqrt{3} }\\ x^{3}+\frac{1}{x^{3}} = ?$ ...........(1)

We know that

$x=\sqrt[3]{2+\sqrt{3} }$

TRANSPOSE ∛ to the other side, it becomes x³.

$x^{3}={2+\sqrt{3} }$ ............ Substitute this in (1).

The result is:

${2+\sqrt{3} }+\frac{1}{2+\sqrt{3} }$

Rationalise $\frac{1}{2+\sqrt{3} }$ .

$2+\sqrt{3} +\frac{1}{2+\sqrt{3}}*\frac{2-\sqrt{3} }{2-\sqrt{3} }$

$2+\sqrt{3} +\frac{2-\sqrt{3} }{(2+\sqrt{3)(2-\sqrt{3})}}$ ................(2)

We know that (a+B)(a-b)=a²-b²

(2+√3)(2-√3)⇒2²-(√3)³⇒4-3⇒1.

Thus, (2+√3)(2-√3)=1.......Substitute this in (2).

$2+\sqrt{3} +\frac{2-\sqrt{3} }{1}$

$2+\sqrt{3} +{2-\sqrt{3}$ ......(REARRANGE the terms)

$2+2+\sqrt{3}-\sqrt{3}$ ....................(-√3 and √3 gets cancelled, 2+2=4.)

=4

Thus, (b) is the correct option.

What point on y-axis is at a distance of 5units from the point (-3,4)?

Answer»

Given ,

The point on y axis is at a distance of 5 UNITS from the point (-3 , 4)

Let , the point on y axis be (0 , y)

We know that , the distance b/w TWO POINTS is given by

$\boxed{ \tt{Distance = \sqrt{ {( x_{2} - x_{1})}^{2} + {( y_{2} - y_{1})}^{2} } }}$

THUS ,

$\mapsto \tt 5 = \sqrt{ {(0 + 3)}^{2} + { (y - 4) }^{2} }$

$\mapsto \tt 25 = 9 + {y}^{2} + 16 - 8y$

$\mapsto \tt 25 = 25 + y(y - 8)$

$\mapsto \tt y(y - 8) = 0$

$\mapsto \tt y = 0 \: \: or \: \: y = 8$

★ The point on the y axis will be (0,0) or (0,8)
