8 (a) 7 + 6x – x2 factorises to

(7 – x)(1 + x)

(b) Roots are; x = 7 and x = -1

(c Turning Point halfway between –1 and 7.

i.e. x = 3

So y = 7 + (6 x 3) – (32)

= 7 + 18 – 9

= 16

Main Grid

Solution

OLN = 90° (tangent)

PLJ = 90° – 47° = 43°

PKL = 90° (angle in a semi circle)

PLK = 180° – (90° + 31°) = 59°

KLJ = PLK + PLJ

= 43° + 59° = 102°

Solution

Solution

• x + y = 130 eq 1 x 50

• 30x + 50y = 6000 eq 2

• 50x + 50y = 6500

• 30x + 50y = 6000

• Subtract 20x = 500

• x = 25

• Sub into eq 1 25 + y = 130

• y = 105

Solution

Solution

• Yes. Mean temperature of 19°C is within range of 15°C to 25°C

• Standard deviation of 3.65 °C is less than 5 °C so less variation should mean good growth.

Solution

=(30 x 46) + (3.14 x 15²)

=2086.5 cm²

Volume of prism = Ah

= area of cross section x height

= 2086.5 x 25

= 52162.5 cm³

= 52 000 cm³ (2 sig figs)

(b) So volume of quarter of a cylinder.

Vol = ¼πr2h

30 000 = ¼ x 3.14 x r2 x 20

r2 = 30 000 x 4

3.14 x 20

r = √1910.8 = 43.7cm
