(10)

Draw the triangle 


Hence we have A+B+C = 180

50+80+C = 180

130+C = 180

C = 180 - 130

C = 50


(i)

The bearing of B from C = 90 - 50 = 40°


(ii) 

Bearing of A from B

90+50(alternate angle to A) 

= 140°


(iii) 

Distance between B and C

Using sine rule 

C/sinC = a/SinA

40/sin50 = a/sin50

Cross multiply 

asin50 = 40sin50

a = 40km

Hence distance between B and C = 40km


(iv) 

Using cosine rule 

b²= a²+c² - 2acCosB

where a = 40, c= 40 and B=80

b² = 40²+40² -2*40*40cos80

b² = 1600+1600 - 3200(0.1736)

b² = 3200 - 555.52

b² = 2644.48

b = √2644.48

b = 51.42km


(v)

Height of ΔABC

Draw the triangle 


Area of the triangle 

=1/2acSinB

=1/2*40*40sin80

=800(0.9848)

=787.84km²

Hence 1/2bh=787.84

bh=2*787.84

h=2*787.84/b

h=2*787.84/51.42

h=30.64

=31

8 + 4 + 1 = 2x +1

X = 12/2 = 6


(2b)

Sin x = 12/13 = 0.9231

Z = sin-¹ 0.9231 = 67.4º

Therefore 3 sin x + ½ cos x

= 3 sin 67.4 + ½ cos 67.4

= 3 x 0.9232 + ½ x 0.3843

= 7.7696 + 0.1921

PQ x 90º  [angle in a semicircle]

QPO = 90º - 62 [ angle in a triangle]

Therefore POZ = 28º [alternative angles]

(ii)

PXZ = ½ x 28º = 14º [angle at center is twice angle at cirumfeence]


(3b)

6/5 + 3/x+3 – 9/5(x+3)

126y = 86

1 x y² 2 x y¹ + 6 x yº = 86

y² + 2y + 6 = 86

y² + 2y + 6 – 86 = 0

y² + 2y – 80 = 0

y + 10y – 8y – 80 = 0

y (y+10)-8y (y+10) = 0 

y – 8 = 0 or y + 10 = 0

the positive value of y


(6b) Area of triangle = ½ x b x h

Let the Acheal Area = x

Area = ½ x b x h

Base = x – 9x/100 = 93/100

Height = 9x/100 + x = 107x/100

Area = ½ x 93x/100 x 107x/100

=963x/2000

% error = actual Area – wrong/actual area x 100

= x – 963x/2000 /x 100

201p = 402

P = 402/201

P = N2

P = 200K

S²â‚ (3x – 1) (x+2) dx

By expansion’

S²â‚ 3x² + 6x – x – 2 dx

S²â‚ 3x² + 5x – 2 dx

By integrating using d formula

Xn+1/n+1

Therefore 3x ²+¹/2+1 + 5x¹+¹/1+1

= 2xº+¹/0+1 + c

Therefore 3x³/3 + 5x²/2 + 2x/1 + c

Therefore x³ + 5x²/2 + 2x

But x = 2 at higher and are at lower by substituting 2 in x than of value of 1

(2)³ + 5/2(2)² + 2(2) – ((1)³ + 3/2(1) + 2 (1)

8 + 5/2 x 4 + 4 – (1 + 5/2 + 2)

(8bi)

T = 2Ï€ square l/g

Dividing both side by 2Ï€

T/2Ï€ = square root of L/g

By squaring both side

(T/2 Ï€)² = (L/g)²

T²/4 Ï€² = l/g

Cross multiplication

gT²/T² = 4Ï€²L/T² 

g = 4Ï€²L/T²


(8bii)

T = (0.4)1/2 = square root of 0.4

L = 0.04   T1 = 3.14

G = 4Ï€²L/T2 

= 4 x (3.14)² x 0.04/(0.4)²
