=(2*3)^n+1*(3*3)^n*(2*2)^2n/(2*3*3)^n*2^n*(2*2*3)^2n

=2^n+1*2^n+1*3^n*3^n*2^2n*2^2n/2^n*3^n*3^n*2^n*2^n*2^n*3^2n

= 2^n*2^1*2^n*2^1*3^n*3^n*2^n*2^n*2^n*2^n/2^n*3^n*3^n*2^n*2^n*2^n*2^n*2^n*3^n*3^n

= 2^6n*3^2n*2*2/2^6n*3^4n

= (2^6n / 2^6n) *(3^2n / 3^4n)*2*2

=2^6n - 6n * 3^2n - 4n * 4

= 2^0 * 3^-2n * 4

= 4*3^-2n

= 4 * 1/3^2n

= 4/3^2n

6t - 9p = 42 ...(IV)

9P - 4P = -42 + 16

5p = -26

P = -26/5 = -5 1/5

Put p = -26/5 into eqn (I)

3t - 2(-26/5) = 8

3t + 52/5 = 8

3t = 8 - 52/5

3t = 40 - 52/5 = -12/5

Divide both sides by 3

36/3 = -12/5 / 3

t = -12/5 Ã— 1/3

= -12/15 = -4/5

Let the water melon be x

Let the mango be y

12x + 24y = 432 ...(i) Ã— 24

24x + 12y = 360...(ii) Ã— 12

288x + 576y = 10368 ...(iii)

-144y + 576y = -4320+10368

432y = 6048

y = 6018/432 = 14

Put y = 14 into eqn (i)

12x + 24(14) = 432

12x + 336 = 432

12x = 432 - 336

12x = 96

X = 96/12 = 8

(i) Water melon per kg = 8

(ii) Mango per kg = 14

(iii) (3 Ã— 8) + (2 Ã— 14)

(6b)

123x = 83ten

1*X² + 2*X¹ + 3*X^0

X² + 2x + 3 = 83

X² + 2x + 3 - 83 = 0

X² + 2x - 80 = 0

X² + 10x -8x - 80 = 0

X(x+10) - 8(x+10) = 0

Then either

X - 8 = 0 or X + 10 = 0

X = 8 or X = -10

t = 2600/850 = 3.0588hrs

t = 3hours

Time taken to fly to Y from X

DRAW THE TRIANGLE DAIGRAM

|YX| = x + 620

From âˆ† YFP

Tan56 = R/620

R = 620 x tan56

= 620 x 1.4826

h = 919.19m

To find x

Tan 20 = h/x

X = h/tan20 = 919.19/0.3639

X = | XF | = 2525.45m

|YX| = |XF| + |FY|

|YX| = 2525.45 + 620

= 3145.5.45m

Hence the value of |YX| correct to the four significant figure is 3145m

|XY| = 3145m

(9b)

DRAW THE DAIGRAM

|YX|² = |OY|² + |OX|² - 2|OY| |OX| cosÃ˜

(6)² = (5)² + (5)² - 2 (5) (5) cosÃ˜

36 = 25 +25 â€“ 50cosÃ˜

36 = 50 â€“ 50cos Ã˜

50cosÃ˜ = 50 â€“ 36

50cos = 14

cosÃ˜ = 14/50 = 0.28

Ã˜ = cos-¹ (0.028) = 73.34º

Therefore

(9bii)

Let |XZ| = |YZ| = y

|XY|² = |YZ|² + |XZ|² - 2 |YZ| |XZ| Cosã€†

(6)² = y² + y² - 2y² cos 36.87

36 = 0.4y²

y² = 36/0.4 = 60

y = âˆš60 = 7.75m

hence, |XZ| = 7.8m (1dp)
