Answer»

ong>Given : distribution of the total  POPULATION and those who are blind among them

To Find :  is there  any RELATION between age and blindness

Solution:

Age   Population (’000)   No. of Blinds           Blinds %

0—10         150                   90                           0.06

10—20       90                    63                            0.07

20—30      50                     50                           0.1      

30—40        32                   40                           0.125

40—50         20                30                             0.15      

50—60           12                30                            0.25

60—70           5                 20                              0.4          

70—80         2                      12​                           0.6    

Linear

y = 0.007x - 0.061

R² = 0.816   ( not Bad  but not very good)

Quadratic

y = 0.000x² - 0.005x + 0.108

R² = 0.983  

R² value is close to 1. for Quadratic function  

hence Quadratic relation exist between age and Blind %

We can further go for cubic relations as well that would be much closer.

y = 3E-06x³ - 0.000x2 + 0.004x + 0.040

R² = 0.998

Ab is a line segment C is the mid point of line segment prove that

Answer»

ong>ANSWER:

AC=BC  

Step-by-step explanation:

AC=BC     ... (i)

If possible, let D be another mid-point of AB.

AD=DB    ... (II)

SUBTRACTING (ii) from (i)

AC–AD=BC–DB

DC=−DC    (∵AC−AD=DCandCB−DB=−DC)

DC+DC=0

2DC=0

DC=0

So, C and D coincide.

Thus, every line segment has one and only one mid-point.

The sides of a triangle are 52 CM 56 cm and 6 cm find the area of triangle with heron's formula

Answer»

strong>Given:

Side if the triangles are

  • a = 52 cm
  • b = 56 cm
  • C = 6 cm

To FIND:

The area of the triangle by Heron's formula

Heron's Formula

= \sqrt{S(S-a)(S-b)(S-c)} UNITS sq.

Here,

'S' = half of perimeter i.e. (perimeter/2)

And 'a', 'b', and 'c' are the sides of the triangle.

Now,

Periemter of the triangle = sum of all three sides of a triangle

Perimeter = 52 + 56 +  6 = 114

Now,

S = Perimeter/2 = 114/2

S = 57

  • The area of the triangle is

= \sqrt{S(S-a)(S-b)(S-c)} units sq.

= \sqrt{57(57-52)(57 - 56)(57-6)}

= \sqrt{57*(5) *(1) * (51)}

= \sqrt{\underline{<klux>3</klux>}*19*5*1*\underline{3}*17}

= 3\sqrt{19*5*17}

= 3*\sqrt{1615}

= 3 * 40.18

= 120.54 cm sq. (Approx.)

Hence,

  • The area of the triangle with given sides is 120.54 cm sq.

Explain when a quarter is not always equal to a quarter. Illustrate with example

Answer» ONG>Answer:a quarter of Whole  is not  equal to a quarter  when Whole ≠ 1

Step-by-step explanation

Quarter of a Whole  =  Whole/ 4

For example a Pizza has  8 pie  is Full

then Quarter of Whole Pizaa =  8 pie/4  = 2 Pie

in  Mathematics numbers  Quarter  MEAN   1/4

if Whole is  1

then Quarter of Whole  = 1/4

Quarter of Whole = Quarter

if Whole is TAKEN as  2

=> Quarter of Whole = 2/4  = 1/2

=> Quarter of Whole ≠ Quarter

Whenever Whole is not equal to 1

Quarter of Whole  ≠  Quarter

a quarter of Whole  is not always equal to a quarter

Integrate 2 sin x + cos 3x dx​

Answer»

To FIND :

\displaystyle\sf{\int{ \; 2 <klux>SIN</klux> (x)\; .\;<klux>COS</klux> (3x) \;\;dx =\; ?}}

AnswEr :

Given expression is :

\implies\displaystyle \sf{\int{\;2\;sin(x)\;.\;cos(3x)\;\;dx}}

using trigonometric identity

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

\implies\displaystyle \sf{\int{sin(x+3x)+sin(x-3x)\;\;dx}}

\implies\displaystyle \sf{\int{sin(4x)+sin(-2x)\;\;dx}}

using trigonometric identity

sin (-A) = - sin A

\implies\displaystyle \sf{\int{sin(4x)-sin(2x)\;\;dx}}

\implies\displaystyle \sf{\int{sin(4x)\;.\;dx}-\int{sin(2x)\;.\;dx}}

since,

\displaystyle\sf{\int\;sin(ax+b)=\dfrac{-1}{a}cos(ax+b)+c}

(where c is an arbitary constant)

therefore,

\implies\displaystyle \sf{\bigg(\dfrac{-1}{4}cos(4x)\bigg)-\bigg(\dfrac{-1}{2}cos(2x)\bigg)+c}

\boxed{\boxed{\implies\displaystyle \sf{\dfrac{-1}{4}cos(4x)+\dfrac{1}{2}cos(2x)+c}}}

Hence,

Cosec theta+cot theta=√3,sin theta=?​

Answer»

rding to the problem:

Cosec θ + Cot θ = √3      -----(1)

We know that ,

Cosec² θ - Cot² θ = 1

( Cosec θ + Cot θ )(Cosec θ - Cot θ) =1

[ Since a² - b² = ( a + b ) ( a - b ) ]

( √3 ) ( Cosec θ - Cot θ ) = 1      [from (1) ]

Cosec θ - Cot θ = 1 / √3      -----(2)

On adding equations (1) and (2) we get,

    2Cosec θ = √3 + 1 /√3

⇒   2Cosec θ = ( 3 + 1 ) / √3

⇒  2Cosec θ  = 4 / √3

⇒ Cosec θ = 4 /2√3

⇒ Cosec θ = 2 / √3

⇒  Cosec θ = Cosec 60°

∴ θ = 60°

=> Sin θ = sin 60°

=> √3 / 2

taking today as zero on the number line, if the day before yesterday is 17 January, what is the date on 3 days afyer tomorrow answer ​

Answer» ONG>Answer:

23RD January = 4 on Number Line

Step-by-step explanation:

Today is 0.

Day before yesterday = 17th January = -2 (From this, we know, 0 will be dated 19th of January)

Three days after TOMORROW = 3+1 = 4 = 4 days after 19th January = 23rd January

✍️✍️solve this question...​

Answer»

hat NUMBER should { - 30}^{ - 1} be divided to get {6}^{ - 1} ?

❁ \pink{\huge{ \rm{\underline{\underline{Solution }}}}} ❁

Let the number be X

Now, { - 30}^{ - 1} should be divided by x to get {6}^{ - 1}

We know that :-

❍ { - 30}^{ - 1} = \frac{ - 1}{30}

❍ {6}^{ - 1} = \frac{1}{6}

As per the problem, we have:

\frac{ (\frac{ - 1}{30} )}{x} = \frac{1}{6}

◕ \frac{( - \frac { 1}{30} )}{ \frac{1}{6} } = x

◕ x = - \frac{1}{30} \times \frac{6}{1} \: \: ( \because \frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c} )

◕ x = - {\frac{6}{30} } = - \frac{1}{5}

Therefore,

\green{ \underline{ \boxed{ \gray{ x = - \frac{1}{5} }}}}

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

\blue{ \rm{Let's \: verify \: it :-}}

We know,

{ (- 30)}^{ - 1} should be divided - \frac{1}{5} to get {6}^{ - 1}

According to the problem, we have:

\frac{ ({ - 30})^{ - 1} }{ - \frac{1}{5} }

◉ = \frac{ - \frac{1}{30} }{ - \frac{1}{5} }

Minus ( - ) sign will get cancel,

◉ \frac{1}{30} \times \frac{5}{1} = \frac{5}{30}

◉ = \frac{1}{6}

\green{ \underline{ \boxed{ \gray{ {6}^{ - 1}}}}}

Hence, Verified!!

\blue{ \rm{Transposition :-}}

A term may be transposed from ONE side of the equation to the other side, but its sign will change, i.e., plus ( + ) sign will become minus ( - ) and vica versa. Similarly, multiplication ( × ) sign changes into division ( ÷ ) sign and vice versa.

Applying all algebraic rules, we bring the linear variable in one side and other NUMERICAL terms or EXPRESSIONS to the other side of the equation. Then, make the coefficient of the variable 1 (unit).
