The line through the points (-2,a) and (9,3) has slope -1/2.find the value of apls send a pic of the working guys asap

Answer»

ANSWER:

HOPE it will help you

Step-by-step explanation:

SLOPE (m) = y₂-y₁ ÷ x₂ - x₁

-1÷2=3-a ÷ 9+1

-1÷2 = 3-a ÷10

Do CROSS multipy

-10 = 6-2a

2a = 6+10

2a = 16

a = 16÷2

a= 8

Therefore, a= 8

QUESTION :–

$\\ \: \large \to \: { \bold{show \: \: that : \frac{ \sin( \theta) }{1 + \cos( \theta) } + \frac{1 + \cos( \theta) }{ \sin( \theta) } = 2cosec( \theta)}}\\$

ANSWER :–

TO PROVE :–

$\\ \: { \bold{ \dfrac{ \sin( \theta) }{1 + \cos( \theta) } + \dfrac{1 + \cos( \theta) }{ \sin( \theta) } = 2cosec( \theta)}}\\$

SOLUTION :–

• LET's TAKE L.H.S. –

$\\ \: { \bold{ = \dfrac{ \sin( \theta) }{1 + \cos( \theta) } + \dfrac{1 + \cos( \theta) }{ \sin( \theta) } }} \\$

• We should WRITE this as –

$\\ \: { \bold{ = \dfrac{[ 1 + \cos( \theta)] ^{2} + { \sin }^{2} ( \theta)}{ \sin( \theta)[1 + \cos( \theta) ]} }}\\$

$\\ \: { \bold{ = \dfrac{1 + \cos ^{2} ( \theta) + 2 \cos( \theta) + { \sin }^{2} ( \theta)}{ \sin( \theta)[1 + \cos( \theta) ]} \: \: \large [ \: \because \: \: {(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab \: ] \: \: }}\\$

$\\ \: { \bold{ = \dfrac{1 + 1 + 2 \cos( \theta) }{ \sin( \theta)[1 + \cos( \theta) ]} \: \large [ \: \because \: \: {sin}^{2} \theta + {cos}^{2} \: \theta = 1\: ] \: \:}}\\$

$\\ \: { \bold{ = \dfrac{2+ 2 \cos( \theta) }{ \sin( \theta)[1 + \cos( \theta) ]} }}\\$

$\\ \: { \bold{ = \dfrac{2[1 + \cos( \theta) ] }{ \sin( \theta)[1 + \cos( \theta) ]} }}\\$

$\\ \: { \bold{ = \dfrac{2 }{ \sin( \theta)} \: \: \large [ \: \because \: \: \dfrac{1}{ \sin( \theta) } \: \: = cosec (\theta) ] \: \: }}\\$

14.	If x =root5+root4then find the value of x+1/x
Answer» Answer: Step-by-step EXPLANATION: We will solve the question by RATIONALISATION:- In this we multiply the numerator and denominator by the inverse of the sign of the denominator. So we NEED to FIND x+ 1/x. First we will rationalise 1/x $\frac{1}{\sqrt{5}+\sqrt{4} } * \frac{\sqrt{5}-\sqrt{4} }{\sqrt{5}-\sqrt{4}}$ $= \frac{\sqrt{5}-\sqrt{4}}{(\sqrt{5}+\sqrt{4})(\sqrt{5}-\sqrt{4})}$ Using identity (a^2-b^2) in denominator, $\frac{\sqrt{5}-\sqrt{4}}{(\sqrt{5}) ^{2}-(\sqrt{4}) ^{2} }$ $\frac{\sqrt{5}-\sqrt{4}}{5-4} \implies \sqrt{5}-\sqrt{4}$ Now placing the VALUES of x and rationalised 1/x, $\sqrt{5}+\sqrt{4}+\sqrt{5}-\sqrt{4}\\\implies 2\sqrt{5}$ So $2\sqrt{5}$ is the answer.

If x =root5+root4then find the value of x+1/x

Answer»

Answer:

Step-by-step EXPLANATION:

We will solve the question by

RATIONALISATION:-

In this we multiply the numerator and denominator by the inverse of the sign of the denominator.

So we NEED to FIND x+ 1/x.

First we will rationalise 1/x

$\frac{1}{\sqrt{5}+\sqrt{4} } * \frac{\sqrt{5}-\sqrt{4} }{\sqrt{5}-\sqrt{4}}$

$= \frac{\sqrt{5}-\sqrt{4}}{(\sqrt{5}+\sqrt{4})(\sqrt{5}-\sqrt{4})}$

Using identity (a^2-b^2) in denominator,

$\frac{\sqrt{5}-\sqrt{4}}{(\sqrt{5}) ^{2}-(\sqrt{4}) ^{2} }$

$\frac{\sqrt{5}-\sqrt{4}}{5-4} \implies \sqrt{5}-\sqrt{4}$

Now placing the VALUES of x and rationalised 1/x,

$\sqrt{5}+\sqrt{4}+\sqrt{5}-\sqrt{4}\\\implies 2\sqrt{5}$

So $2\sqrt{5}$ is the answer.

Answer» Step-by-step explanation: 5 years AGO, LET the AGE of the son be x years father's age = 7X years After 5 years, that is the present year son's age = x+5 years father's age = 7x+5 years 7x+5 = 3(x+5) 7x+5 = 3x+15 7x-3x = 15+5 4x = 20 x = 20/4 = 5 Son's age = 10 years Father's age = 40 years Hope this helps MARK AS BRAINLIEST

38.

five year age, father age was 7 times the age of his son 5 years later the father age will be 3 times the age of his son find their present age

Answer»

Step-by-step explanation:

5 years AGO,

LET the AGE of the son be x years

father's age = 7X years

After 5 years, that is the present year

son's age = x+5 years

father's age = 7x+5 years

7x+5 = 3(x+5)

7x+5 = 3x+15

7x-3x = 15+5

4x = 20

x = 20/4

= 5

Son's age = 10 years

Father's age = 40 years

Hope this helps

44.	What is letus rectum??? write formula
Answer» Answer: hi dude..... Step-by-step explanation: Mathematics, a conic section is defined as a CURVE which is obtained from the intersection of the SURFACE of a CONE with a plane. There are three different types of conic sections. They are parabola, ellipse and hyperbola. To define these curves, many important terms are used, such as focus, directrix, latus rectum, locus, asymptote, and so on. In this article, let us discuss the TERM “Latus Rectum Length of Latus Rectum of Parabola Let the ends of the latus rectum of the parabola, y2=4ax be L and L’. The x-coordinates of L and L’ are EQUAL to ‘a’ as S = (a,0) Assume that L = (a,b). We know that L is a point of the parabola, we have b2 = 4a (a) = 4a2 Take square root on both sides, we get b = ±2a Therefore, the ends of the latus rectum of a parabola are L = (a,2a), and L’ = (a,-2a ) Hence, the length of the latus rectum of a parabola, LL’ is 4a. hope it helps have a nice day...

Answer:

Step-by-step explanation:

Mathematics, a conic section is defined as a CURVE which is obtained from the intersection of the SURFACE of a CONE with a plane. There are three different types of conic sections. They are parabola, ellipse and hyperbola. To define these curves, many important terms are used, such as focus, directrix, latus rectum, locus, asymptote, and so on. In this article, let us discuss the TERM “Latus Rectum

Length of Latus Rectum of Parabola

Let the ends of the latus rectum of the parabola, y2=4ax be L and L’. The x-coordinates of L and L’ are EQUAL to ‘a’ as S = (a,0)

Assume that L = (a,b).

We know that L is a point of the parabola, we have

b2 = 4a (a) = 4a2

Take square root on both sides, we get b = ±2a

Therefore, the ends of the latus rectum of a parabola are L = (a,2a), and L’ = (a,-2a )

Hence, the length of the latus rectum of a parabola, LL’ is 4a.

hope it helps
