Correct Answer: A. Atomic radius

Correct Answer: A. \(\frac{63}{65}\)

Explanation

\(sin x = \frac{4}{5}\) and \(cos y = \frac{12}{13}\)

x is obtuse i.e sin x = + ve while cos x = + ve

\(cos x=\frac{3}{5}==>cos x=-\frac {3}{5}(obtuse)\)

\(sin y= \frac{5}{13}\)

\(sin (x-y) = sin x\) \(cos y - cos x\) \(sin y\)

\(sin(x-y) = \frac{4}{5}\times\frac{12}{13}-(-\frac{3}{5})\times\frac{5}{13}\)

\(sin(x-y) = \frac{48}{65}-(-\frac{3}{13})\)

\(\therefore sin (x-y) = \frac{48}{65} + \frac{3}{13} = \frac{63}{65}\)

Explanation

Violent Video Games should be Banned.

The Chairman, School Principal, Vice Principals (Administration and Academic), School Teachers, Non-Teaching Staff, Time-keeper, Co-debaters, Fellow students, Ladies and Gentlemen.

I am writing in support of the motion that violent video games should be banned. The reasons for my support is vet obvious. I am in total support, first, because of the word 'violent' linked with video games. Video games on its own has a lot of social and academic gains if properly and timely used but if video games that are violent become the order of the day, the outcome is always not palatable.

However. for the past few years particularly with introduction of cell phones and field computers,l of education. the use of violent video games has been a controversial issue in Nigeria among stakeholders in the field of education. Also, different medical. moral. legal and religious bodies and organizations have aired their views concerning this topical issue. While some stakeholders supported the idea, some vehemently go against it. However, various bodies and organization see many ills in it.

Violent games are video games with lots of activities that tend to portray life as beginning and ending in on( see many ills in it. physical power and attributes only. We all know that this assumption is not correct. This is why I have come to support the motion that violent video games should be banned.

In the first place, future leaders must not be tutored with violence. Nothing can be achieved at permanent level in a state of anarchy. A lot of human and material resources are often wasted in violent activities, hence it must not be supported.

Second. in our society today, gangsterism. cultism, armed robbery. kidnapping and other criminal activities have become a way of life. This is made possible and easy in a society that encourages and supports violent video games. In my candid opinion, video games is bad and not to talk of adding violence to it.

Ladies and gentlemen, all the ills in our society can be traced to the doorstep of violent video games. A person that got himself or herself addicted to video game habit is a moving train with no clear-cut destination. The destination is a disaster for the train and people around it. Hence, all hands must be on the deck to rid club houses of illicit video games.

In schools, many students behave like touts and uncultured persons due to the type of materials they watch. A wise man says that a person's destiny can be developed or destroyed by the things he sees. Therefore, a man that sees good things act in a good way while a man that sees bad things is expected to behave and act likewise.

Moreover. if we want our country's future and future of generations yet unborn to be in safe hands, we must discourage violent video game from our environment.

Lastly, many people have argued that violent video games can be useful in military services and situations. We all know that this is not a gospel truth.

I hope I have convinced you that violent video games should be banned. Thank you very much
