In a classroom, 4 friends are seated at the points A, B, C and D as shown in Fig. 7.8. Champa and Chameli walk into the class and after observing for a few minutes Champa asks Chameli, “Don’t you think ABCD is a square?” Chameli disagrees. Using distance formula, find which of them is correct.

Fig. 7.8

Let A(3, 4), B(6, 7), C(9, 4) and D(6, 1) be the given points. Then

]

We see that,
AB = BC = CD = DA
and    AC = BD
Therefore, ABCD is a square.
Hence, Champa is correct.

The rain with large hailstorm had ruined Lencho’s field of ripe corn. So he was sad. His only hope was—help from God. So he asked God for money.
बड़े ओलावृष्टि के साथ हुई बारिश ने लेनो के पके मकई के खेत को बर्बाद कर दिया था। इसलिए वह दुखी था। उनकी एकमात्र आशा थी - ईश्वर से सहायता। इसलिए उसने भगवान से पैसे मांगे।

No doubt Hari is a thief as well as good human being. Situations compel a person to become either beast or remain as a human being. Even goodness and nobility of a person changes anyone’s heart and mind.

The series can be written as

(5 + 9 + 13 + .... + 81) + [(- 41) + (- 39) + (- 37) + (- 35) ... (- 5) + (- 3)]

For the series (5 + 9 + 13 + ... + 81)

a = 8

d = 9 - 5 = 5

and a(n) = 81

Then, a(n) = 5 + (n - 1)4 = 81

or, (n - 1)4 = 76

⇒ n = 20

S(n) = 20/2(5 + 81)

= 860

For Series (- 41) + (- 39) + (- 37) + (- 35) ... (- 5) + (- 3)

a(n) = - 3

a = - 41

d = 2

Then, a(n) = - 41 + (n - 1)(2)

⇒ n = 20

Now, S(n) = 20/2[- 41 + (- 3)]

= - 440

Sum of the series = 860 - 440

= 420

Hence, the sum of the following series is 420.

Barriers or restrictions that are imposed by government on free import and export activities are called trade barrier. Tax on imports is a vital trade barrier. Government can use the trade barriers in the following ways :

(a) Increase or decrease of foreign trade of the country.
(b) With the help of trade barriers government can decide what kinds of goods and how much of each, should be traded in the country.

 Internet is also known as the World Wide Web (www) is a global system of interconnected computer networks that use a protocol called the Internet Protocol Suite (TCP/IP) to link to billions of devices all around the world. The impact of this has been so enormous that it has been referred to as the 8^th continent of the world. This carries a vast range of information, from the top-secret military and research files to the most trending and viral video of the week. This massive storage is shared by everyone, with everyone’s computer contributing to the ever-expanding treasure trove of knowledge.

The definition of courage for Mandela was to win and attain victory over fear. For him, the absence of fear was not the meaning of being courageous. He considered men to be brave when they had the courage to conquer fear. He does not wanted a condition in the society where the men would be fearless.

In 1930, Sir Muhammad Iqbal, as president or the Muslim League, reiterated the importance of separate electorates for the Muslims as an important safeguard for their minority political interests. His statement is supposed to have provided the intellectual justification for the Pakistan demand that came up in subsequent years.

(d) Combination Reaction

Explanation:

Combustion is a chemical process or a reaction between Fuel (Hydrocarbon) and Oxygen. When fuel and oxygen react it releases the heat and light energy. Heat and light energy then result in the flame. So, the formula for Combustion reaction is Hydrobcarbon + Oxygen = Heat energy.

Given equation 
x2+px+q
Also, given p,q are the roots of the equation.
p+q=−p  
2p=−q    .....(1)
And   pq=q
q(p−1)=0
⇒q=0 or p=1
So, by (1), q=0⇒p=0  
Hence, the values of p are 0,1.

The chemical equation for the reaction of lead sulfide with ozone follows:

By stoichiometry of the reaction:

1 mole of lead sulfide reacts with 4 moles of ozone.

So, 1 molecule of lead sulfide will react with  molecules of ozone.

Or

PbS + O₃ --> PbSO₄

After balancing

3PbS + 4O₃ --> 3PbSO₄

The sight of the bus that travelled between her village and the nearest town, filled each time with a new set of passengers, was a source of unending joy for Valli. Her strongest desire was to ride the bus. Valli found out that the bus journey to the town took 45 minutes and the one-way fare costed 30 paisa.

If d is the hcf of 48 and 72 so the value of d will be the hcf of later
factor of 48 is
2,3,4,6,8,12,24 and 48
factor of 72 is
2,3,4,6,8,9,12,24,36 and 72
so the hcf is 24 and d= 24
or
d = HCF ( 48, 72 )

48 = 2 * 2 * 2 * 2 * 3

72 = 2 * 2 * 2 *3 * 3

so HCF = 2 * 2 * 2 * 3

➡ 24

Answer :- d = HCF ( 48, 72 ) = 24

Let 2+√3 is a rational number.
A rational number can be written in the form of p/q.
2+√3=p/q
√3=p/q-2
√3=(p-2q)/q
p,q are integers then (p-2q)/q is a rational number.
But this contradicts the fact that √3 is an irrational number.
So,our supposition is false.
Therefore,2+√3 is an irrational number.
Hence proved.
