27cm2
30cm2
36cm2
37cm2
Correct answer is A
Area = \(\frac{1}{2}(a + b)\)h
where a = QR = 6cm
b = PA = 10cm
Area = \(\frac{1}{2}(6 + 10)\) x 3.35cm2
= \(\frac{1}{2}(16)\) x 3.35cm2
= 26.8cm2
= 27cm2 (approx.)
3.35cm
3.73cm
4.50cm
4.62cm
Correct answer is A
h = ?
\(\frac{h}{5cm}\) = sin 45o
h = 5cm x 0.6691 = 3.35cm
The following is the graph of a quadratic friction, find the value of x when y = 0
1, 2
1, 4
2, 3
1, 6
Correct answer is B
when y = 0, value of x = roots of the equation
x2 - 5x + 4 = 0
x = 1, 4 (see graph)
The following is the graph of a quadratic friction, find the co-ordinates of point P
(0, 4)
(4, 0)
(0, -4)
(-4, 0)
Correct answer is A

Find the quadratic equation whose roots are -\(\frac{1}{2}\) and 3
2x2 - 2x + 3 = 0
2x2 - 2x - 3 = 0
2x2 - 5x - 3 = 0
3x2 - 5x - 3 = 0
Correct answer is C
x = \(\frac{-1}{2}\)
x = 3
2x = -1, x = 3; 2x + 1 = 0
x - 3 = 0
(2x + 1)(x - 3) = 0
2x2 - 6x + x - 3 = 0
2x2 - 5x - 3 = 0
