12. The Autorikshaw fare in a city is charged Rs 10 for the first kilometer and @ Rs 4 perkilometer for subsequent distance covered. Write the linear equation to express the abovestatement. Draw the graph of the linear equation.​

Answer»

Let the total distance be x KM

and total cost be y

now, 10RS for 1st km, and 4Rs. per km for rest

so,

y=1(10)+4(x-1)

y=4x+6,

 

sub,

x=-2,y=-2

x=-1, y=2

 

so PLOT points (-2,-2),(-1,2)

scale : 1CM = 1 unit on both axis

Answer»

Answer:

\frac{dy}{dx}  =  \frac{ \sqrt{1 -  {y}^{2} } }{ \sqrt{1 -  {x}^{2} } }

\frac{dy}{ \sqrt{1 -  {y}^{2} } }  =  \frac{dx}{ \sqrt{1 -  {x}^{2} } }

INTEGRATING both SIDES, we get

\sin {}^{ - 1} (y)  =  \sin {}^{ - 1} (x)  + c

. A box contains 15 red balls, 18 white balls. One ball is taken out of the box at random. What is the probability that the ball taken out will be not red.​

Answer»

GIVEN :

A box CONTAINS 15 red balls, 18 white balls.

• One ball is taken out of the box at random.

TO FIND :

• Probability that the ball taken out will be not red = ?

SOLUTION :

• We know that –

☆ Probability = N(E)/n(S)

▪︎ E → Taken ball is not red.

=> E → Taken ball is white.

ㅤㅤ

=> n(E) = \bf ^{18} c_{1}

▪︎ S → One ball TAKE from 33 balls.

=> n(S) = \bf ^{33} c_{1}

• So that –

\bf \implies \:Probability =  \dfrac{^{18} c_{1}}{^{33} c_{1}}

• Using identity –

\bf \implies  ^{n} c_{r} =  \dfrac{n!}{(n - r)!(r)!}

• So that –

\bf \implies \:Probability =  \dfrac{ \dfrac{18!}{(18 - 1)!(1)!}}{\dfrac{33!}{(33 - 1)!(1)!}}

\bf \implies \:Probability =  \dfrac{ \dfrac{18!}{(17)!}}{\dfrac{33!}{(32)!}}

\bf \implies \:Probability =  \dfrac{ \dfrac{(18)(17)!}{(17)!}}{\dfrac{(33)(32!)}{(32)!}}

\bf \implies \large{ \boxed{ \bf Probability =  \dfrac{18}{33}}}

Rational NUMBERS are represented in p/q form where q is not equal to zero.

Irrational numbers are the numbers that cannot be represented as a simple FRACTION. It is a contradiction of rational numbers but is a type of REAL numbers.

Depending on the two numbers, the product of the two irrational numbers can be a rational or irrational number.

Example:

Consider √3 and √3 then

√3 × √3 = 3 It is a rational number.

Consider √3 and √2

√3 × √2 = √6

It is an example of an irrational number.

In the following AP's fill up the missing terms .. 4) __, 7 __, __ 1​

Answer»

Answer:

The missing TERMS in the sequence of A.P are 9, 7, 5, 3, 1

Step-by-step explanation:

Given that,

the sequence of A.P is __, 7, __, __, 1

Here, a₁ = ?, a₂ = 7, a₃ = ?, a₄ = ?, a₅ = 1

common difference (d) = ?

(∵aₓ = a+(n-1)d )

so, a₂ = a+(2-1)d

⇒ 7 = a+d ↔ (1)

a₅= a+(5-1)d

⇒1 = a+4d ↔ (2)

now, SUBTRACT (1) from (2)

⇒eq.(1) - eq.(2)

⇒ 7-1 = a+d - (a+4d)

⇒ 6 = a+d-a-4d

⇒ 6 = -3d

⇒ d = -2

thus, common difference (d) = -2

By substituting d = -2 in eq.(1) we get,

⇒7 = a+d

⇒7 = a-2

⇒a = 7 + 2 = 9

⇒ a = a₁ = 9

So,

a₃ = a + (3-1)d

⇒ a₃ = 9 + 2(-2)

⇒ a₃ = 9 - 4

⇒ a₃ = 5

a₄ = a + (4-1)d

⇒ a₄ = a+3d

⇒ a₄ = 9+3(-2)

⇒ a₄ = 9 - 6

⇒ a₄ = 3

∴ the missing terms are 9, 5, 3

the sequence of A.P is 9, 7, 5, 3, 1

72 students of a certain school were asked to indicate a place of interest in Delhi they wouldlike to visit on a holiday. The table below shows the results​

Answer»

Step-by-step explanation:

We can draw the bar graph by following the given steps:

Step 1.- On a graph paper, draw a horizontal LINE OX as x-axis and vertical line OY as y-axis.

Step 2.- Along OX, write the names of the subjects at the POINTS that are taken at a uniform gap.

Step 3.- Choose the scale:

1 big DIVISION = 10 marks

1 small division = 1 mark

Step 4.- Heights of the various bars are:

Hindi = 43 small divisions = 4 big divisions and 3 small divisions

English = 56 small divisions = 5 big divisions and 6 small divisions

Maths = 80 small divisions = 8 big divisions

Science = 65 small divisions = 6 big divisions and 5 small divisions

Social Science = 50 small divisions = 5 big divisions

Step 5.- Draw bars of equal width on the x-axis. The difference between the two bars should also be the same.

Hope it helps you

10). A bicycle wheel whose diameter is 77cm makes 50 revolutionsin 20 seconds. Find the speed in km/h​

Answer»

Answer:

HERE IS YOUR ANSWER ...

Step-by-step explanation:

DIAMETER = 77 cm

= 0.00077 km

TIME = 20s

= 0.00555 h

Circumference= 22/7 x 77/100000

= 0.00242 Km

50 revolution= 0.00242 x 50

= 0.121

Speed = distance/time

= 0.121/0.00555

= 12100/555

= 21.8 km/h
