(1a)
110x = 40s
Converting both sides to base 10, we have;
(1xX²)+(1xX¹)+(0×X^0) = (4×5¹) + (0×5^0)
X² + X + 0 = 20 + 0
X² + X - 20 = 0
X² + 5x - 4x - 20 = 0
X(x+5)-4(x+5) = 0
(x-4)(x+5) = 0
Since X must be positive
X - 4 = 0
X = 4

15/√75 + √108 + √432
= 15/√25×3 + √36×3 + √144×3
=15/5√3 + 6√3 + 12√3
= 3/√3 + 18√3
=3√3/3 + 18√3

The equation of the line through the points
A(-2,7) and B(2,-3)
Using the equation Y=mx+b
Where m=slope of the gradient, b=the intercept at the vertical axis
Hence slope=Change in Y/Change in X
=>Y2-Y1/X2-X1=Y-y1/X-x1
=(-3-7)/(2--2)=Y-7/X+2
=-10/4=(Y-7)/(X+2)
=4(y-2)=-10(x+2)
4y-28=-10x-20
4y=-10x+8
5x+2y=4

(5b-a)/(8b+3a)=1/5
5(5b-a)=1(8b+3a)

Ali : Masah : Yusuf = #420,000
3 : 5 : 8
Sum of ratio shared :
3 + 5 + 8 = 16
Therefore
Ali share = 3/16 × 420,000
= #78,750

Musah Share = 5/16 × 420,000
=#131,250

Yusuf share = 8/16 × 420,000
=#210,000

Therefore
Sum of Ali + Yusuf
=#78,750 + #210,000
= #288,750

Solve : 2(1/8)² = 32^x-1
2¹ × (8^-1)^x = 32^x-1
2¹ × (2^-3(-1))^x = 2^5(x - 1)
2¹ × (2^-3)^x = 2^5x - 5
2¹ × 2^-3x = 2^5x - 5
2^1+(-3x) = 2^5x - 5
2^1-3x = 2^5x - 5
1 - 3x = 5x - 5
-3x - 5x = -5 - 1
-8x/-8 = -6/-8
X = 3/4

Since Using Pythagoras theorem
|PR|² = |PQ|² + |QR|²
|PR|² = 3² + 4²
|PR|² = 9 + 16
|PR|² = 25 PR = √25
|PR| = 5cm
Considering PRS
|PS|² = |PR|²+|SR|²
13² = 5² + |SR|²
169 = 25 + |SR|²
|SR|² = 169 - 25
|SR|² = 144
|SR| = √144 = 12cm

Hence the area of the quadrilateral = Area of triangle PQR + area of PRS
= 1/2bh + 1/2bh
= 1/2×4×3 + 1/2×12×5
= 6+30 = 36cm

No of red balls = 3
No of green balls = 5
No of blue balls = x
Prob.(red ball) = no of total outcome/no of possible outcome
Pr(red) = 3/3+5+x = 1/6
3/8+x = 1/6
6(3) = 1(8+x)
18 = 8 + x
X = 18 - 8 = 10
Therefore the no of blue ball = 10

#26,000 = 100%
X = 130%
X = 26000 × 130/100

Then 65kg was then sold at reduction of 12% per kg
Recall that the initial cost price = 52000/130
=400kg
65kg sold at = 33,000/65
=#520/kg
Then for 12% reduction
520 × 88/100 = 457.6/kg

(2b)
(i)Agriculture
Areas with well developed farming of crops or animals are often densely populated.
(ii) Secondary industry
Those areas in which manufacturing has developed tend to be densely populated. It is worth noting that even in old industrial areas in which manufacturing has declined or even closed, population densities may remain high.
(iii) Accessibility
Areas with well developed transport infrastructure and links through road, rail, shipping, canals and air are likely to be more densely populated than areas which are poorly connected
(iv)Conflict
Wars and conflicts can lead to significant movements of population and a simultaneous decrease in density in some areas while others may increase.

(2c)
(i)Healthcare/access to health care/medical technology/ability to fight or prevent disease
(ii)Availability of birth control/availability of family planning education/use of birth control

(II)it leads to increased agricultural, mineral and industrial production
(III)It aids the movement of people or labour and capital
(IV)it gives rise to employment opportunities
(V)It links areas of production with areas of consumption
in a country


(4b)

(i)Climatic conditions such as temperature and rainfall significantly influence the groundnut production. Warm and moist conditions are very favorable than cool and wet climate, which results in slow germination and seedling emergence, increasing the risk of seed rot and seedling diseases.

(ii) Temperature is a major environmental factor that determines the rate of crop development. Temperatures above 35°C inhibit the growth of groundnut. Optimum mean daily temperature to grow is 30°C and growth ceases at 15°C. For rapid emergence, soil temperature above 21°C is needed. The optimum temperature for the most rapid germination and seedling development is about 30°C.

(iii). A minimum 100 - day optimum temperature growing season is necessary for successful groundnut crop production. Adequate and well distributed rainfall during the growing season, especially during flowering, pegging and pod formation stages, is essential for maximum yield and quality of groundnut. Groundnut is grown in areas receiving 600 to 1500 mm of rainfall. However, the crop can be grown successfully with a rainfall of 1250 mm.

(4c)

-Nigeria is one of the countries of the world with a variety of oil seeds notably groundnut, oil palm, soybean and cotton seeds. Vegetable oils are used principally for food (mostly as shortening, margarines, and salad and cooking oils) and in the manufacture of soap and other products.

-Groundnut is by far the most nutritive oil-seed used in West Africa. The kernels have an average fat and protein content of 75% and an energy value of 360 kcal/100g, compared to 60% and 430 kcal/100 g for soybeans.

-In Nigeria, Groundnut provides high quality cooking oil and is an important source of protein for both human and animal diet and also provides much needed foreign exchange by exporting kernels and cake.

- As population continues to grow the demand for edible oil in many developing countries such as Nigeria will also continue to grow.

-Groundnut will continue to be important in satisfying this growing demand because it is adaptable to a wide range of environments from sandy soils of the Sahel to favorable irrigated areas

Population density of country B= Total population of B/Land area of B
= 26,000,000/ 479,000
= 557.41 person/sqkm
(2b)
(i)Agriculture
Areas with well developed farming of crops or animals are often densely populated.
(ii) Secondary industry
Those areas in which manufacturing has developed tend to be densely populated. It is worth noting that even in old industrial areas in which manufacturing has declined or even closed, population densities may remain high.
(iii) Accessibility
Areas with well developed transport infrastructure and links through road, rail, shipping, canals and air are likely to be more densely populated than areas which are poorly connected
(iv)Conflict
Wars and conflicts can lead to significant movements of population and a simultaneous decrease in density in some areas while others may increase.

(i)Healthcare/access to health care/medical technology/ability to fight or prevent disease
(ii)Availability of birth control/availability of family planning education/use of birth control
(iii)Culture-social norms, values, and traditions (the use of contraception, the age at which marriage is socially acceptable, religious beliefs on family planning, gender equality, etc.)

2(b)
B. Physical Factors
1. Relief and landforms
Lowland plains, flat river valleys and deltas and volcanic areas with fertile soil tend to have high population densities. Mountainous areas with steep slopes and poor quality soil tend to have low population densities.

2. Weather and climate
Temperate areas which experience few extremes of weather and climate tend to be more attracted than areas which experience extremes. Areas which are very dry, very cold or very wet tend to have sparse populations whereas areas which have a moderate climate with evenly distributed rainfall or with monsoon type climates have denser populations.

3. Soil type and quality
Areas which have rich, fertile soils allowing successful agriculture tend to have higher population densities than areas which have poor quality soils have sparse populations. Good quality soils may be found in low lying areas such as river flood plains and deltas where silt is deposited; in volcanic areas; in areas which have a high natural humus content. Poor quality soils may be found in areas with steep slopes; areas with very high rainfall throughout the year which tends to leach nutrients fro the soil; cold areas of permafrost; areas experiencing soil degradation through human management e.g. over-grazing/deforestation.

4. Water supply
Water supply is essential for human survival and development and because of this areas which have sufficient water (but not too much) tend to have denser populations than areas which are dry or suffer from regular drought or areas which have excessive rainfall or which may be prone to flooding.

5. Vegetation
Some types of vegetation make the development of settlement more likely, e.g. grasslands. Areas with particularly dense rainforest, coniferous forests or those with little vegetation tend to have sparse populations.

6. Raw materials/natural resources
Areas with a wealth of natural resources such as oil, coal or minerals may have higher population densities than areas which do not. It is important to remember though that natural resources may be found in otherwise harsh environments and that they may be traded and exported/used in areas other than where they are extracted.

7. Natural threats
These may affect population density as people may try to avoid areas where pests, threatening animals and diseases are particular risks.

Human Factors
1) Agriculture
Areas with well developed farming of crops or animals are often densely populated.

2) Secondary industry
Those areas in which manufacturing has developed tend to be densely populated. It is worth noting that even in old industrial areas in which manufacturing has declined or even closed, population densities may remain high.

3) Accessibility
Areas with well developed transport infrastructure and links through road, rail, shipping, canals and air are likely to be more densely populated than areas which are poorly connected

4) Political decisions
Government policy can have a significant impact upon population densities. This can occur if governments decide to open up previously underdeveloped areas (e.g. Brasilia and the development of the Trans-Amazonian Highway in Brazil; the movement of Han Chinese to Tibet; the development of Abuja as a new capital city in Nigeria). If governments decide not to invest in an area it may also lose large numbers of people leading to reduced population density.

5) Conflict
Wars and conflicts can lead to significant movements of population and a simultaneous decrease in density in some areas while others may increase.

Economic IMPORTANCE OF GROUNDNUT

-Nigeria is one of the countries of the world with a variety of oil seeds notably groundnut, oil palm, soybean and cotton seeds. Vegetable oils are used principally for food (mostly as shortening, margarines, and salad and cooking oils) and in the manufacture of soap and other products.

-Groundnut is by far the most nutritive oil-seed used in West Africa. The kernels have an average fat and protein content of 75% and an energy value of 360 kcal/100g, compared to 60% and 430 kcal/100 g for soybeans.

-In Nigeria, Groundnut provides high quality cooking oil and is an important source of protein for both human and animal diet and also provides much needed foreign exchange by exporting kernels and cake.

- As population continues to grow the demand for edible oil in many developing countries such as Nigeria will also continue to grow.

-Groundnut will continue to be important in satisfying this growing demand because it is adaptable to a wide range of environments from sandy soils of the Sahel to favorable irrigated areas

Question 1.....solution tips....

*Advise to a friend wanted to continue his university abroad*


*1. Forget Hesitation*

Just go. Don’t think, don’t hesitate. It will change your life forever. It will open your eyes to the world, to a new perspective of life. It will give you an opportunity to meet people from all over the world and give you the ability to adapt to unknown situations. Studying abroad had the most incredible impact on my life, and I couldn’t imagine my life without my experience abroad. It has led me to be the person I am today. So go, just do it, with no hesitation. It will be the best decision of your life.


 *2. Don’t Limit Yourself*

My advice would be to not have any expectations. In my experience, I set so many expectations before I went, based on my limited perspective of what I was really getting myself into. You’ll quickly realize that the majority of your expectations become limitations. There’s so much more the world has to offer, than what you’ve seen from your front door. Every day is going to give you the opportunity to set expectations while you’re in your host country; sights to see, things to do, friends to make–it’s all going to unfold in a way you could have never expected! I studied with a few kids who didn’t get the full experience, because it wasn’t what they expected it to be, and they ended up disappointing themselves. If you’re going to expect anything, expect to have an adventure.



*3. Take Advantage of Every Adventure*

Say yes. Study abroad is a once in a lifetime opportunity. Never again will you have the freedom and ability that you do during your time abroad; even if you do, you will never be as young. Skydiving? Yes. Spontaneous weekend trips to Barcelona? Yes. Climb the Eiffel Tower? Yes. “Twenty years from now you will be more disappointed by the things you didn’t do,” so do not be quick to turn down adventures that come your way.


*4. Actually Make Local Friends*

After my 5 months abroad the one thing I kept asking myself over and over was, “Who are my Spanish friends?” If I could go back and do it all over again I would definitely try to integrate myself much more. Whether it be going to local coffee shops, making friends with the local grocery store cashier, or even hanging out with the on-site staff, I always think of how much more I could have grown. Don’t get me wrong, I became a better, more well-rounded person but there is always that little voice in the back of my head wishing I would have dropped my US friends and got out there to meet the Spanish Locals!


*5. Jump the Hurtles*

 It Takes to Get There
Just do it! I am not particularly fond of the Nike way sometimes, but this is an opportunity that may not appear again. It can be a great amount of paperwork and preparation, but the best things in life are never easy to achieve. Studying abroad is an experience that is a privilege. Not everyone gets to go away for four or five months to study in Another World. So, get past the paperwork, grab your passport, and go beyond your comfort zone. I guarantee that however many summer jobs you juggle to reach your destination will be worth it.

A drug is a substance uѕеd fоr mеdісаl рurроѕеѕ thаt change thе ѕtаtе оr funсtіоn оf the bоdу.

She laughed and called out to Bittoo.he came out and started running towards her. Arti ran faster so that he could not catch her and her foot slipped.down she fell on the wet slushy grass.she hit the ground and blacked out for some time.her mother ran out to the lawn picked her up and carried her inside. Dr. Kohli ,who lived Next Door was called. he checked Arti and advised her rest for a week as her foot was sprained.
if only she had listened to her mother.if only she had been more self-discipline she would not have to suffer this way. all the while that she had to stay in bed resting Arti thought a lot about what she could learn from the incident.
She realised " I wish I had listened to my mother"

               First and foremost, the task has not been easy at all My experience as a Library Prefect is quite mi pac ful and painful As Library Prefect, I'had face-off with many of my friends. Some of them will come f books
and refuse to return them as t when due We had wurse to quarrel because I always want to ensure diligence on the office

                Also, I always miss classes in order to attend to issues related to the Library upkeep. I see to how the Library is kept clean by the science in charge, I make sure all the books and materials are arranged
orderly and alphabetically as they were in the Catet everyday
