(2a)
Given that the roots of the equation are
X = -2/3 and X = -3/2
3x = -2 and 2x = -3
3x + 2 = 0 and 2x + 3 =0
(3x+2)(2x+3) = 0
6x² + 9x + 4x + 6 = 0
6x² + 13x + 6 = 0
(3a)
Given : R(3,5) and S(-2, -6)
equation to line through them is :
y-5/x-3 = -6-5/-2-3
y-5/x-3 = -11/-5
y-5/x-3 = 11/5
5(y-5)= 11(x-3)
5y-25 = 11x-33
5y-11x = 25-33
5y-11x = -8 or 11x-5y = 8
(3b)
RS= √(X1X2)² (y1y2)²
√(-2-3)² + (-6-5)²
√(-5)² + (-11)²
√25 + 121
√146

X/x+101 = 11/1000
Since all the members are in binary, convert all to denary (base 10)
Xbase2 = Xbase10
101base2 = (1×2^2)+(1×2^0) = 4+1 = 5base10
11base2 = (1×2¹)+(1×2raise to power 0) = 2+1 = 3base10
1000base2 = 1×2^3 = 8base10
X/X+101 = 11/1000 –> X/X+5 = 3/8
3(x+5) = 8(x)
3x+15 = 8x
15 = 8x – 3x
15 = 5x
15/5 = 5/5
X = 3
Convert X=3 to base 10 to base 2
2|3
2|1R1
|0R1
.:. x = 11
(6c)
Given that log5 base 10 = 0.699
and log3 base 10 = 0.477
10
Log75 base 10 = log(3×5×5) base 10
(7a)
Given that Y=2×2+7x-6
To find the gradient of the curve at the point x=3
dy/dx=4x+7 (at x=3)
dy/dx=4(3)+7
dy/dx=19
(7bi)
Ade bought 7kg of maize + 4kg of meat=N4240
Kemi bought 3kg of maize + 5kg meat =N4610
Let x = 1kg of maize and y=1kg of meat
Therefore 7x+4y=4240—–(eq1)
3x+5y=4610———(eq2)
Substituting simultaneously
Multiply eq1 by 3 and eq2 by 7
21x+12y=12720—eq3
21x+35y=32270—eq4
Substract eq3 from eq4
23y=19550
23y/23=19550/23=850
y=850
Substitute y=850 in1
7x+4y=4240
7x+4(850)=4240
7x=4240-3400
x=840/7
=120
Hence the total cost price per Kg of maize is N120.00 while the total cost per kg of meat is N850.00
(7bii)
Total cost of 10kg of maize and 5kg of meat
=10x+5y
=10(120)+5(850)
1200+4250
=N5450 CLICK HERE FOR THE IMAGE

Draw the diagram
Q(34.5°N, 22.3°W)
P(34.5°N, 38.7°E)
R(35.4°S, 38.7°E)
Distance between P and Q along the parallel of latitude
D = Φ/360 × 2πr
Where r = RcosΦ
Φ = 38.7° + 22.3° = 61°
Q = 34.6°
R = 6400km
D = 61/360 × 22/7 ×6400cos34.6
D =1717760(0.8231)/252
D = 5,610.66768
= 5,610km
(9b)
|PR|=(34.6+35.4)/360 * 2 *22/7*6400
=70/360 * 44/7 *6400
=19712000/2520
=7820km(3 sf)
Therefore the shortest distance between P and R = 7820km(3 sf)
(9c)
Circumference of the circle of latitude through R = 2πr where r = RcosΦ
= 2πRcosΦ
= 2 × 22/7 × 6400cos35.4
=281600/7(0.8151)
= 229,532.16/7
= 32,790.3
= 32,800km (3 s.f) CLICK HERE FOR THE IMAGE
