How good are you with figures and formulas? Find out with these Mathematics past questions and answers. This Test is useful for both job aptitude test candidates and students preparing for JAMB, WAEC, NECO or Post UTME.
Cos x is negative and sin x is negative.Which of the following is true of x?
0o < x < 90o
90o < x <180o
180o < x < 270o
270o < x <360o
-90o < x <90o
Correct answer is C
In the 3rd quadrant, only the tan of angles are positive.
The 3rd quadrant = 180° < x < 270°
If log\(_{10}\) q = 2.7078, what is q?
5102
849.9
510.2
84.99
51.02
Correct answer is C
q = 10\(^{2.7078}\)
Antilog of 2.7078 = 510.2
What value of k makes the given expression a perfect square ? m\(^2\) - 8m + k = 0
2
4
8
16
64
Correct answer is D
Take half the coefficient of m and square it
=> (-8/2)2 = k = 16
Find the root of the equation 2x\(^2\) - 3x - 2 = 0
x = -2 or 1/2
x = -2 or1
x = -2 or 2
x = -1 or 2
x = -1/2 or 2
Correct answer is E
2x\(^2\) - 3x - 2 = 0
2x\(^2\) - 4x + x - 2 = 0
2x(x - 2) + 1(x - 2) = 0
(2x + 1)(x - 2) = 0
x = \(\frac{-1}{2}\) or x = 2
Evaluate log106 + log1045 - log1027 without using logarithm tables
0
1
1.1738
1.3802
10
Correct answer is B
log106 + log1045 - log1027
log10 \(\frac{6 \times 45}{27}\)
= log102 x 5
log1010 = 1
