Correct answer is D
\(\frac{0.8 \times 0.43 \times 0.031}{0.05 \times 0.72 \times 0.021}\) x \(\frac{10}{10}\) = 14.11
Find \(\frac{dy}{dx}\), if y = \(\frac{2}{3}\) x\(^3\) - \(\frac{4}{x}\)
3x2 - \(\frac{4}{x}\)
2x2 +\(\frac{4}{x^2}\)
3x2 + \(\frac{4}{x^2}\)

Evaluate \(\frac{27^\frac{1}{3} - 8^\frac{2}{3}}{16^\frac{2}{4} \times 2}\)
\(\frac{23}{5}\)
-\(\frac{23}{5}\)
-\(\frac{1}{8}\)
\(\frac{21}{7}\)
Correct answer is C
\(\frac{27^\frac{1}{3} - 8^\frac{2}{3}}{16^\frac{2}{4} \times 2}\)
\(\frac{27^\frac{1}{3} - 8^\frac{2}{3}}{16^\frac{2}{4} \times 2}\) = \(\frac{3\sqrt{27} - 3\sqrt{8}^2}{\sqrt{16} \times 2}\)
\(\frac{3 - 4}{4 \times 2}\)
= \(\frac{-1}{8}\)
Calculate the perimeter of a sector of a circle of raduis 9cm and angle 36o.
18cm
(18 + \(\frac{9\pi}{5}\))cm
(9 + \(\frac{9\pi}{5}\))cm
\(\frac{9\pi}{5}\)cm
Correct answer is B
Perimeter = 2r + \(\frac{\theta}{360}\) x 2\(\pi\)r
2(9) + \(\frac{36}{360}\) x 2 x \(\pi\) x 9 = 18 + \(\frac{9\pi}{5}\)
