Correct Answer: C. 0.0028

Explanation

2.7864 x 10^-3 = 0.0027864

= 0.0028(approx. 2 s.f)

Correct Answer: D. 25

Explanation

From y = \(\frac{1}{2} \sqrt{x}\)

when y = 2.5 or \(\frac{5}{2}\), x = P

\(\frac{5}{2} \times \frac{1}{2} \sqrt{P}\)

\(\sqrt{P} = \frac{10}{2} = 5\)

P = 5²

= 25

Correct Answer: C. External memory

Explanation

An-Nabawiyyah wa Al-Fada‘il Al-Mustafawiyyah), a compilation of hadiths concerning the person and character of the Islamic prophet, Muhammad. At-Tirmidhi was also well versed in Arabic grammar, favoring the school of Kufa over Basra due to the former's preservation of Arabic poetry as a primary source . ?Al-`Ilal As-Sughra?, ?Az-Zuhd?, ?Al-`Ilal Al-Kubra?, ?Al-Asmaa‘ wa Al-Kuna?, ?Kitab al-Tarikh? were written by Abu Isa Tirmidhi as well . B. “Al-Jami’ as-Sahih”: Publications and Commentaries ?Al-Jami` as-Sahih? is one of the most important book in Sunni Islamic world. According to the historian Ibn Hajar al-Asqalani, al-Tirmidhi wrote this work in 270 AH (884 AH), when he was about sixty years of age, after having gained considerable experience in science and becoming an imam . Manuscripts of this work have been preserved in many cities around the world, as well as in the Academy of Sciences of Uzbekistan, Oriental Studies Institute named after Abu Raykhan Beruni. ?Al-Jami` as-Sahih? has been repeatedly published as an important source. For instance, it was published in Mitoh 1283 (1866), Cairo in 1292 (1875), and in Beirut in 1980. Several commentaries were written for this work such as ?Aridhat al-Ahwathi bi Sharh Sunan al-Tirmidhi? by Ibn al-Arabi (d. 543H )(1148-49 CE), ?Sharh Jaami' al-Tirmidhi? of which only the last portion of remains – ?Sharh 'Ilal at-Tirmidhi? by Ibn Rajab, ?Commentary on al-Tirmidhi's Hadith Collection? by al-Zayn al-Iraqi, Footnotes, including explanation and verification, of approximately the first third of the Sunan by Ahmad Muhammad Shakir, ?Al-?Urf al Shadhi Sharh Sunan Al-Tirmidhi? by Anwar Shah Kashmiri, ?Tuhfat Al-Ahwadhi Bi Sharh Jami? Al-Tirmidhi? by 'Abd al-Rahman al-Mubarkafuri, ?Fuyoodh Un Nabi, Sharh Jami Al Tirmidhi? (in Urdu Language) by 'Allama Mufti Muhammad Arshad ul Qadri' . C. Structure and contents It should be mentioned that the third century of the Hijri (ninth century AD) is a golden period in the development of hadith science. The fruitful work of such scholars as Imam al-Bukhari and Imam Muslim, who lived and worked at that time, is of great importance. Abu Isa Tirmidhi made a great contribution to the hadith science which was started collecting and sorted by his teachers: Imam Bukhari and Imam Muslim. He became one of the most influential scholars in the Muslim world. ?Al-Jami` as-Sahih? plays an important role in hadith [4]. The author divides his work into separate chapters and, whenever possible, quotes each hadith. After each hadith, it specifies the degree of reliability or weakness. Earlier we mentioned that the work was called ?Al-Sunan? (?Sunan at-Termizi?). One of the main reasons for this name is that it contains a great deal of hadiths concerning fiqh. In addition, there are many hadiths about discipline, ethics, and good manners in the work, and it is not an exaggeration to say that hadiths of this level are not found in any author's work. Structurally, the work is divided into the following chapters: purification, salat (prayer), al-witr, the day of Friday, the two eids, traveling, zakat, fasting, hajj, jana'iz (funerals),marriage, suckling, divorce and li'an, s on judgements from the messenger of allah, blood money, legal punishments (al-hudud), hunting, sacrifices, vows and oaths, military expeditions, virtues of jihad, jihad, clothing, food, drinks, righteousness and maintaining good relations with relatives, medicine, inheritance, wasaya (wills and testament), wala' and gifts, al-qadar, al-fitan, dreams, witnesses, zuhd, the description of the day of judgement, ar-riqaq, and al-wara', the description of paradise, the description of hellfire, faith, knowledge, seeking permission, manners, parables, the virtues of the qur'an, recitation, tafsir, supplication. Overall, this work consists of 48 chapters . These chapters are divided into chapters in the title, and the hadiths of the chapter fully reflect the contents of the chapter. The author cites a number of hadiths on the subject of this chapter and then expresses the views of other scholars on the subject

Correct Answer: B. laid off

Explanation

(a) Entrepôt trade involves the importation of goods from one country and re-exportation of the goods to another country.

(b)(i) Advantages of International Trade:

• International trade widens the market for goods;
• It avoids wastage because countries can dispose off the goods they have in excess;
• It improves the standard of living because countries can enjoy what they cannot produce;
• It creates more jobs as in transporting, selling, manufacturing because of the need to increase production to meet foreign demands;
• It brings about specialization and mass production which in turn results in lower unit cost of the product;
• It generates revenues for the countries involved;
• It fosters international relations;
• It encourages the transfer of technology;
• It promotes economic development.

(ii) Disadvantages of International trade:

• It kills local industries whose products cannot compete with those from developed countries;
• It puts the country into perpetual dependency on foreign goods;
• It leads to dumping;
• It may lead to the importation of harmful goods;
• It creates unemployment in importing countries;
• It leads to unfavourable balance of payment.

Explanation

< AOB = 108\(^o\) - (90\(^o\) + 40\(^o\))

= 180\(^o\) - 130\(^o\) = 50\(^o\)

< DCO = 40\(^o\) (Alternate angle)

< ODE = \(\frac{180^o - 80^o}{2}\) = \(\frac{100^o}{2}\)

= 50\(^o\)

(b)(i)

(b)(ii) Area of the parallelogram

= ab sin \(\theta\)

= 5cm x 7cm sin 125\(^3\)

= 35 sin 125

= 28.7cm\(^2\)

(c)

x = \(\frac{1}{2}(1 - \sqrt{2})\)

evaluate (2x\(^2\) - 2x)

= 2[\(\frac{1}{2}(1 - \sqrt{2})^2\)] - 2[\(\frac{1}{2} (1 - \sqrt{2}\))]

= 2[\(\frac{1}{4}(1 - 2\sqrt{2} + 2)\)] - 1 + \(\sqrt{2}\)

= 2[\(\frac{1}{4}(3 - 2\sqrt{2})\) - 1 + \(\sqrt{2}\)]

2[\(\frac{3}{4} - \frac{1}{2} \sqrt{2} - 1 + \sqrt{2}\)]

= \(\frac{3}{2} - \sqrt{2} - 2 + 2\sqrt{2}\)

= \(\frac{1}{2} + \sqrt{2}\)
