Correct Answer: D. IV

Correct Answer: A. Fosuwa

Correct Answer: C. bank draft

Correct Answer: D) copper

Correct Answer: B)

r = Kd\(^{-\frac{1}{2}}\)

Explanation

(a) \(1001_{2} = 1 \times 2^{3} + 0 \times 2^{2} + 0 \times 2^{1} + 1 \times 2^{0}\)

= \(8 + 0 + 0 + 1\)

= 9

\(\sqrt{9} = 3_{10}\)

\(\therefore \sqrt{1001_{2}} = 11_{2}\)

(b) In \(\Delta QOP, OQ = OP\)

\(\therefore QK = KP\)

\(\Delta QOK = \Delta POK\) (right- angled triangle)

In \(\Delta POK\),

\(OP^{2} = PK^{2} + OK^{2}\)

\(x^{2} = y^{2} + (\frac{z}{2})^{2}\)

\(\frac{z^{2}}{4} = x^{2} - y^{2}\)

\(z^{2} = 4x^{2} - 4y^{2}\)

\(z = \sqrt{4(x^{2} - y^{2})}\)

\(z = 2\sqrt{x^{2} - y^{2}}\)

(c)(i) \(< PSQ = \frac{1}{2}(< POQ) = \frac{1}{2}(160°)\)

= 80°

In \(\Delta PSQ\),

\(< PQS + < QPS + < PSQ = 180°\)

\(40° + < QPS + 80° = 180°\)

\(< QPS = 180° - 120° = 60°\)

(ii) \(< PSR = < PSQ + < QSR\)

= \(80° + 45°\)

= \(125°\)

\(< PQS = < PQO + < RQS \)

= \(40° + < RQS\)

\(< PSR + < PQS = 180°\)

\(\therefore 125° + 40° + < RQS = 180°\)

\(< RQS = 180° - 165°\)

= \(15°\)

Correct Answer: B. systemic circulation

The Dangers of Keeping Bad Company in School.

It is sad to note that many young ones in schools today go out with groups that turned out to be the ones that change their good destiny.

The holy book says: show me your friend and I will tell you who truly you are. A popular proverb also supports this statement when it says: Birds of the same feather flock together.

According to the English Advanced Learners Dictionary a company is a group of people with a common set of goals and objectives, while a school is a place created in order to acquire knowledge that would make a learner a better and useful person to himself and others in future.

One important cornerstone that needs individual contribution is the choice of a company to stay with. A company is by choice and not by force. Today. in most of our schools. students select companies without weighing the social, political economic and educational gains of such relationship They end up regretting their actions. Some of them started games whose end they do not know Usually they end in shame that may be difficult to remedy. Examples abound in society where students from good homes turned to wolves with human skin.

Therefore it is very important to itemize factors that generate bad company its effect and what can be done to curb or put an end to it

Many factors contribute to the growth of bad groups in schools in recent times Major among them are: parents attitude to their children at home wrong societal value. and the cash and carry syndrome in society.

First, most parents fail in their God-ordained responsibility to control their children and wards at home. Some parents put this responsibility of managing their children and wards on school teachers, who themselves have a lot to do

Furthermore. we are in a society with wrong values, a society where survival of the fittest is the order of the day. a society without decorum.

In addition, the materialistic state of society also contributed to this Most bad groups in schools put their focus on material liberation instead of educational liberation The result is what we are witnessing in schools today.

The dangers of keeping bad gangs or company in school are numerous and very damaging to the academic and social souls of the school system. a place expected to be the product for the best brain needed for the development of the country.

First, it brings about the growth of gangsterism in schools. Gangs are groups of elite students that can do anything o protect the interest of their members Gangs have destroyed the unity of many schools.

Second, bad company is usually the birth place of many notorious cult groups we have in society today. Their activities are too numerous to mention.

Third bad company leads to poor academic performance of students. This is due to the fact that academically poor students use it as a forum to protect their incompetence and thereby terrorize their teachers when they fail. Criminal activities that are very rampant in schools today got their roots from bad associations.

Therefore. all stakeholders in the field of education must wake up to their responsibility of making sure that bad groups are curbed or eradicated from schools. it is in interest of everybody.

Correct Answer: C. are alternative jobs in the same location

Correct Answer: A. -5

Explanation

x² + 7x + 10 = 0

x² + 5x + 2x + 10 = 0

x(x + 5) + 2(x + 5) = 0

(x + 2)(x + 5) = 0

x + 2 = 0 or x + 5 = 0

x = -2 or x = -5

the smaller value x = -5
