If sin x + sin y = 4/5 and sin x - sin y = 2/7 prove that 5 tan (y + x)/2 + 14 tan( y - x)/2 = 0

Answer»

Use of Identities :-

$\boxed{ \sf \: sinx + siny = 2sin\bigg(\dfrac{x + y}{2} \bigg)<klux>COS</klux>\bigg(\dfrac{x - y}{2} \bigg)}$

$\boxed{ \sf \: sinx - siny = 2cos\bigg(\dfrac{x + y}{2} \bigg)sin\bigg(\dfrac{x - y}{2} \bigg)}$

$\boxed{ \sf \: tan( - x) = - tanx}$

$\large\underline{\bf{Solution-}}$

Given that,

$\rm :\longmapsto\:sinx + siny = \dfrac{4}{5} - - - (1)$

and

$\rm :\longmapsto\:sinx - siny = \dfrac{2}{7} - - - (2)$

On dividing equation (1) by equation (2), we get

$\rm :\longmapsto\:\dfrac{sinx + siny}{sinx - siny} = \dfrac{4}{5} \times \dfrac{7}{2}$

$\rm :\longmapsto\:\dfrac{2sin\bigg(\dfrac{x + y}{2} \bigg)cos\bigg(\dfrac{x - y}{2} \bigg)}{2cos\bigg(\dfrac{x + y}{2}\bigg) sin\bigg(\dfrac{x - y}{2} \bigg)} = \dfrac{14}{5}$

$\rm :\longmapsto\:\dfrac{sin\bigg(\dfrac{x + y}{2} \bigg)cos\bigg(\dfrac{x - y}{2} \bigg)}{cos\bigg(\dfrac{x + y}{2}\bigg) sin\bigg(\dfrac{x - y}{2} \bigg)} = \dfrac{14}{5}$

$\rm :\longmapsto\:\dfrac{tan\bigg(\dfrac{x + y}{2} \bigg)}{tan\bigg(\dfrac{x - y}{2} \bigg)} = \dfrac{14}{5}$

$\rm :\longmapsto\:5tan\bigg(\dfrac{x + y}{2} \bigg) = 14tan\bigg(\dfrac{x - y}{2} \bigg)$

$\rm :\longmapsto\:5tan\bigg(\dfrac{x + y}{2} \bigg) = - 14tan\bigg(\dfrac{y - x}{2} \bigg)$

$\rm :\longmapsto\:5tan\bigg(\dfrac{x + y}{2} \bigg) + 14tan\bigg(\dfrac{y - x}{2} \bigg) = 0$

$\large{\boxed{\boxed{\bf{Hence, Proved}}}}$

Trigonometry Formulas

sin(−θ) = −sin θ

cos(−θ) = cos θ

tan(−θ) = −tan θ

cosec(−θ) = −cosecθ

sec(−θ) = sec θ

COT(−θ) = −cot θ

PRODUCT to Sum Formulas

sin x sin y = 1/2 [cos(x–y) − cos(x+y)]

cos x cos y = 1/2[cos(x–y) + cos(x+y)]

sin x cos y = 1/2[sin(x+y) + sin(x−y)]

cos x sin y = 1/2[sin(x+y) – sin(x−y)]

Sum to Product Formulas

sin x + sin y = 2 sin [(x+y)/2] cos [(x-y)/2]

sin x – sin y = 2 cos [(x+y)/2] sin [(x-y)/2]

cos x + cos y = 2 cos [(x+y)/2] cos [(x-y)/2]

cos x – cos y = -2 sin [(x+y)/2] sin [(x-y)/2]

Sum or Difference of ANGLES

cos (A + B) = cos A cos B – sin A sin B

cos (A – B) = cos A cos B + sin A sin B

sin (A+B) = sin A cos B + cos A sin B

sin (A -B) = sin A cos B – cos A sin B

tan(A+B) = [(tan A + tan B)/(1 – tan A tan B)]

tan(A-B) = [(tan A – tan B)/(1 + tan A tan B)]

cot(A+B) = [(cot A cot B − 1)/(cot B + cot A)]

cot(A-B) = [(cot A cot B + 1)/(cot B – cot A)]

cos(A+B) cos(A–B)=cos^2A–sin^2B=cos^2B–sin^2A

sin(A+B) sin(A–B) = sin^2A–sin^2B=cos^2B–cos^2A

Multiple and Submultiple angles

sin2A = 2sinA cosA = [2tan A /(1+tan²A)]

cos2A = cos²A–sin²A = 1–2sin²A = 2cos²A–1= [(1-tan²A)/(1+tan²A)]

tan 2A = (2 tan A)/(1-tan²A)

Please give me answer fast of coordinate geometry

Answer»

ANSWER:

Distance between points A and B is 5 unit.

Step-by-step explanation:

Suppose coordinates of point A are ( X1, y1) and of point B are (x₂, y₂)

∴ x1 = 2, y1 = 9, x₂=5, y₂=5

By distance formula,

$AB = \sqrt{ {(x₂ - x1)}^{2} + {(y₂ - y1)}^{2} }$

$= \sqrt{ {(5 - 2)}^{2} + {(5 - 9)}^{2} }$

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

$= \sqrt{9 + 16}$

$= \sqrt{25}$

Answer» Given: a = -1.25 d = -0.25 To find: First four terms of the A.P Solution: From the question, we are provided with the values of a and d. Since, we know that a means first term of an A.P, First term = -1.25 Still we need to find three terms. We know that, → d = Second term - First term → Second term = d + First term → Second term = (-0.25) + (-1.25) → Second term = -0.25 - 1.25 → Second term = -1.5 Similarly, → d = Third term - Second term → Third term = d + Second term → Third term = (-0.25) + (-1.5) → Third term = -0.25 - 1.5 → Third term = -1.75 Finally, → d = FOURTH term - Third term → Fourth term = d + Third term → Fourth term = (-0.25) + (-1.75) → Fourth term = -0.25 - 1.75 → Fourth term = -2 Hence, the four terms of A.P are -1.25, -1.5, -1.75 and -2.

A=-1.25,d=-0.25 write first four terms of AP,when first term a and 'd'are given as follows

Answer»

Given:

a = -1.25
d = -0.25

To find:

First four terms of the A.P

Solution:

From the question, we are provided with the values of a and d. Since, we know that a means first term of an A.P,

First term = -1.25

Still we need to find three terms. We know that,

→ d = Second term - First term

→ Second term = d + First term

→ Second term = (-0.25) + (-1.25)

→ Second term = -0.25 - 1.25

→ Second term = -1.5

Similarly,

→ d = Third term - Second term

→ Third term = d + Second term

→ Third term = (-0.25) + (-1.5)

→ Third term = -0.25 - 1.5

→ Third term = -1.75

Finally,

→ d = FOURTH term - Third term

→ Fourth term = d + Third term

→ Fourth term = (-0.25) + (-1.75)

→ Fourth term = -0.25 - 1.75

→ Fourth term = -2

Hence, the four terms of A.P are -1.25, -1.5, -1.75 and -2.

The GENERAL form of A.P is a, (a + d), (a + 2d), (a + 3d), etc...

Answer»

Answer:

The required answer is 119/90 .

Step-by-step explanation:

Let X = 1.322... ---------------(i)

So, 10x = 13.22 ------------(ii)

then, 100x = 132.22 ---------------------(iii)

Subtracting EQUATION (ii) from (iii) we get

→ 100x - 10x = 132.22 - 13.22

→ 90x = 119

→ x = 119/90

Hence, the required answer is 119/90 where p & Q are INTEGERS and q ≠ 0.

Answer» Answer: First ODD number is 49 Second odd number is 51 . Step-by-step explanation: Let the first number be = x then, another consecutive odd number be = x+2 Now, It is GIVEN that the SUM of these TWO consecutive odd number is 100 ________________________________________ According to the Given Statement → x + (x+2) = 100 → 2x + 2 = 100 → 2x = 100-2 → 2x = 98 → x = 98/2 → x = 49 So, the first odd number is 49 and the second consecutive odd number is 51 .

Sum of two consecutive odd numbers is 100. What are the numbers ?Let the first number be xThen the second number = _____Sum of the numbers = 100x+x+2 = 1002x + _ = 1002x = _x = Numbers = _ , ___

Answer»

Answer:

First ODD number is 49
Second odd number is 51 .

Step-by-step explanation:

Let the first number be = x

then, another consecutive odd number be = x+2

Now,

It is GIVEN that the SUM of these TWO consecutive odd number is 100

________________________________________

According to the Given Statement

→ x + (x+2) = 100

→ 2x + 2 = 100

→ 2x = 100-2

→ 2x = 98

→ x = 98/2

→ x = 49

So, the first odd number is 49 and the second consecutive odd number is 51 .

However, when a businessman wants to increase his sales or introduce a new product in the market, he usually faces hardship due to competition prevailing in the market. To counter it, goods are sometimes sent to the customers on sale or return basis. Here, goods sent on ‘approval’ or ‘on return’ basis means goods are delivered to the customers with the option to retain or return them WITHIN a specied period.

In mathematics test given to 10 students the following marks (out of 100) arerecorded: -11, 09, 40, 37, 90, 40, 95, 55, 40, 65 find the mean, median and mode of thisdata

Answer»

Step-by-step explanation:

Given:-

In mathematics test given to 10 students the following marks (out of 100) are

recorded: -

11, 09, 40, 37, 90, 40, 95, 55, 40, 65 .

To find:-

Find the mean, median and mode of this

data

Solution:-

Mean:-

Given observations are:

11, 09, 40, 37, 90, 40, 95, 55, 40, 65

SUM of all observations

= 11+9+40+37+90+40+95+55+40+65

=482

NUMBER of all observations = 10

We know that

Mean = Sum of all observations/Number of all observations

=> Mean = 482/10

Mean = 48.2

Median :-

Given observations are:

11, 09, 40, 37, 90, 40, 95, 55, 40, 65

On writing them into ascending order

09, 11 , 37 , 40, 40, 40, 55 ,65 , 90 , 95

Number of all observations = 10

It is an even number

We know that

The number of observations is n an even number then median is the average of the (n/2)th and

(n/2)+1 th observations

n/2 th observation

=> 10/2

= 5th observation = 40

6th observation = 40

Median = (40+40)/2

Median = 80/2

Median = 40

Mode :-

Given observations are:

11, 09, 40, 37, 90, 40, 95, 55, 40, 65

On writing them into ascending order

09, 11 , 37 , 40, 40, 40, 55 ,65 , 90 , 95

Most occuring observation = 40

40 occurs 3 times

Mode = 40

Answer:-

1)Mean = 48.2

2)Median = 40

3)Mode = 40

Used formulae:-

Mean = Sum of all observations/Number of all observations

The number of observations is n an even number then median is the average of the (n/2)th and
(n/2)+1 th observations

Mode is the most frequent occuring observation of the given data.
