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.
240°
150°
60°
270°
Correct answer is A
Sinθ = \(\frac{6}{12}\)
Sinθ = \(\frac{1}{2}\)
θ = Sin\(^0.5\)
θ = 30°
Bearing of Z from X, (270 - 30)° = 240°
List all integers satisfying the inequality in -2 < 2x-6 < 4
2,3,4 and 5
2,3
2,5
3,4
Correct answer is D
-2 < 2x - 6 AND 2x - 6 < 4
-2 + 6 <2x AND 2x < 4 + 6
4 <2x AND 2x < 10
: 2
27
15
3.5
32
Correct answer is A
If log\(_9\)x = 1.5,
9\(^{1.5}\) = x
9^\(\frac{3}{2}\) = x
(√9)\(^3\) = 3
∴ x = 27
Factorize completely 81a\(^4\) - 16b\(^4\)
(3a + 2b)(2a - 3b)(9a2 + 4b2)
(3a - 2b)(2a - 3b)(4a2 - 9b2)
(3a - 2b)(3a + 2b)(9a2 + 4b2)
(6a - 2b)(8a - 3b)(4a3 - 9b2)
Correct answer is C
81a\(^4\) - 16b\(^4\) = (9a\(^2\))\(^2\) - (4b\(^2\))\(^2\)
= (9a\(^2\) + 4b\(^2\))(9a\(^2\) - 4b\(^2\))
N:B 9a\(^2\) - 4b\(^2\) = (3a - 2b)(3a + 2b)
e = 1
e = -1
e = -2
e = 0
Correct answer is D
Identity(e) : a \(\ast\) e = a
m \(\ast\) e = m...(i)
m \(\ast\) e = me + m + e
Because m \(\ast\) e = m
: m = me + m + e
m - m = e(m + 1)
e = \(\frac{0}{m + 1}\)
e = 0
