Correct Answer: A. Hair

Correct Answer: A) Theories of consumer behaviours and production

Explanation

The question is asking us to identify which concepts are relevant to indifference curve and isoquant. Indifference curve is a graph that shows the different combinations of two goods that a consumer can choose from while remaining indifferent or having the same level of satisfaction. On the other hand, isoquant is a graph that shows the different combinations of two factors of production that can be used to produce a certain level of output.

So, which of the options is correct? Option A is the correct answer. Indifference curve and isoquant are respectively relevant to the theories of consumer behavior and production. Consumer behavior is the study of how consumers make decisions to spend their available resources on goods and services, while production theory is the study of how firms make decisions about what goods and services to produce and how to produce them.

To summarize, indifference curve and isoquant are important concepts in economics that are respectively relevant to the theories of consumer behavior and production. Understanding these concepts can help us make better decisions as consumers and producers.

101101₂ = 1 x 2⁵ + 0 x 2⁴ + 1 x 2³ + 1 x 2² + 0 x 2¹ + 1 x 2⁰ = 32 + 0 + 8 + 4 + 0 + 1 = 45₁₀

Correct Answer: B. Ananias

Correct Answer: D. 5 - x

Explanation

\(\frac{2}{x - 3} - \frac{3}{x - 2}\) = \(\frac{p}{(x - 3)(x - 2)}\)

\(\frac{2(x - 2) - 3(x - 3)}{(x - 3)(x - 2)}\) = \(\frac{p}{(x - 3)(x - 2)}\)

= \(\frac{2x - 4 - 3x + 9}{(x - 3)(x - 2)}\) = \(\frac{p}{(x - 3)(x - 2)}\)

\(\frac{-x + 5}{(x - 3)(x - 2)} = \frac{p}{(x - 3)(x - 2)}\)

p(x - 3)(x - 2) = -x + 5(x - 3)(x - 2)

p = -x + 5 or p = 5 - x

Correct Answer: A. Trees are not in pure stand

Explanation

The poet presents an image of a world before colonialism which brought great devastation. The dominant image is that of commerce: "We had traded in this market competitively perfect", suggesting peace.

The picture changes dramatically, however, when colonization sets in to disrupt the erstwhile peaceful co-existence. The metaphor of "cut our ribs, dried our cows" and "burst the cowshed" presents a picture of devastation affecting agriculture and the economy which have been the bulwark of the people's prosperity. The very natural environment is not spared by the reference to words like "drought" and "famine". The blackman's confidence is thus crowded as he is cut off from his means of livelihood.

After presenting such a grim picture of life after colonialism the poet enters into a state of personal lamentation. This is captured by the hyperbole in "my tears flowed to flooded streams", while the allusion to Sodom and Gomorrah presages the complete penury into which the poet has sunk. The image of the debtors and creditors at "my rusty door" is poignant. He has become the laughing stock of others as what is left of his miserable possessions is auctioned. The devastation brought in by colonialism is total and the poet's own life becomes a veritable testament.

Explanation

(a) (i)Pollution;is the release of toxic or harmful substances into the environment by their natural forces or man and other animals to an extent that causes biological damage to man and his resources.

(1) Pollutants of air are:Smoke, fumes, dust, harmful gases e.g sulphurdioxide, hydrogen sulphide, ammonia, chlorine/nitrogen oxides, carbon monoxide, pollen grains and soot.

(2) Pollutants of water are:sewage, excreta/faeces, pesticides, chemical wastes/chemicals from factories, fertilizers, slurry/waste from farms, petroleum/ crude oil, heated water, oil spillage.

(b)(i) Effects of water pollution on organisms are:

(1) Destruction or death of valuable aquatic species such as sea birds, fishes e.t.c.

(2) Food chain is affected, or disrupted.

(3) Pollutants encourage bacterial growth leading to reduced amounts of dissolved oxygen/biological oxygen demand in water. This leads to death of fishes and other organisms.

(4) Causes algae blood or putrification while water is rendered unsafe for domestic, drinking, industrial use or recreation.

(5) It also leads to migration of water animals.

(ii) Ways of preventing water pollution:

(1) There should be efficient and proper sewage disposal system.

(2) Dumping of refuse or petro-chemical by-products into rivers/streams/ponds or seas should be avoided.

(3) The use of efficient techniques to deal with or prevent oil spillage should be adopted.

(4) Industries should be sited away from residential areas and water bodies.

(5) Government /local authorities should strictly monitor all industrial wastes and carry out public enlightenment.

(6) Industrial effluents and hot water should be re-cycled.

(c)(i) Sources of noise pollution are:

(1) Factory or industrial noise.

(2) Aeroplane/aviation noise (taking off and landing of aeroplanes).

(3) Railway engine/locomotive noise.

(4) Automobile/ car horns/sirens.

(5) High pitched musical sounds from loud speakers/drumming.

(6) Noise from mills/sawmills/ grinding mills/electronic gadgets and generators.

(7) Artillary shots /shelling/canon shots.

(8) Thunder noise.

(ii) Effects of noise pollution on man:

(1) Loss of hearing /deafening /hard hearing/hearing difficulty.

(2) Emotional disorder/anxiety / fright and lack of concentration.

(3) High blood pressure/hypertension.
