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.
y = Q + \(\frac{P}{x^2}\)
y = Q + px
y = \(\frac{PQ}{x^2}\)
y = Q - \(\frac{P}{x^2}\)
Correct answer is A
Given the above statement,
\(y = Q + \frac{P}{x^{2}}\)
Express 130 kilometers per second in meters per hour
7.8 x 10-5
4.68 x 106
7,800,000
4.68 x 108
7.80 x 105
Correct answer is D
1km = 1000m
60sec. = 1 mins
60 mins. = 1 hr
130000m per sec = 130000 x 3600
= 468000000m/hr
= 468 x 108 m/hr
It does not rise
2\(\sqrt{3}\) meters
3 meters
1 meter
3
Correct answer is D
Cos 60o = \(\frac{PD}{2}\)
Cos 60o x 2 = 0.5 x 2
= 1m
Find the values of x for which the expression \(\frac{(x - 3)(x - 2)}{x^2 + x - 2}\)
1, -2
-1, 2
2, 3
-1. -2
-2, -3
Correct answer is A
to find the values of x for which the expression is underlined, let x2 + x - 2 = 0
By factorizing, we have (x + 2)(x - 1) = 0
when x + 2 = 0, when x - 1 = 0, x = -2 or x = 1
The two values are -2 and 1
Express 37.05 x 0.0042 in standard form
15.561 x 102
1.5561 x 10-4
1.556 x 10-1
1.5561 x 101
1.55 x 101
Correct answer is C
37.05 x 0.0042 in standard form
\(\begin{array}{c|c}No. & log \\\hline 37.05 & 1.5688\\ 0.0042 & 3.6232 \\ \hline & 1.1920\end{array}\)
= 0.1556
= 1.556 x 10-1
