Correct Answer: C. 2000J

Correct Answer: D. high growth rate

Explanation

a.

-Collect healthy cassava stem cuttings of about 25cm long each with a good number of buds/nodes

-Plant the stem cuttings in slanting position or at an angle of 45°

-Bury about 2/3 of the stem cuttings in the soil with the buds facing upwards

-Observe the buds above the soil surface which develop new shoots while the buds buried in the soil develop new roots

b.

-Can be processed into Garri/flakes/chips/flour/tapioca/consumed as food

-Cassava flour is used in baking

-Cassava meal/chips/peels are used as animal feed

-Alcohol can be extracted from the tubers

-Can be processed into starch

-Dextrose can be extracted from the tuber/pharmaceutical uses

-Can be processed into adhesive/glue

ci.

Spacing = 100 cm x 100 cm

1 m = 100 cm

Spacing =1m x 1m =1m2.

Area of farmland = 1.5 ha

1 ha = 10,000 m2

Area of farmland = 1.5 x 10,000 m2

15,000 m2

Expected number of yam plants on the farmland

= Area of farmland/Spacing

15,000 m2 / 1 m2

=15,000 yam plants

cii. Average weight of one yam tuber = 3.5 kg

Total weight of yam tubers harvested 3.5 kg x 15,000=52,500 kg

d. Diet is the amount of feed regularly given or consumed by a farm animal

While

Ration is the amount of feed that is given to a farm animal daily/over a 24 hour period

Explanation

(a) \((2 - x)^{5} = 2^{5} + 5[2^{4}(-x)^{1}] + 10[2^{3}(-x)^{2}] + 10[2^{2}(-x)^{3}] + 5[2^{1}(-x)^{4}] + (-x)^{5}\)

= \(32 - 80x + 80x^{2} - 40x^{3} + 10x^{4} - x^{5}\)

(b) \((1.98)^{5} = (2 - 0.02)^{5}\)

= \(32 - 80(0.02) + 80(0.02)^{2} - 40(0.02)^{3} + 10(0.02)^{4} - (0.02)^{5}\)

= \(32 - 1.6 + 0.032 - 0.00032 + ...\)

\(\approxeq 30.4317\) (4 d.p)
