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.
Make q the subject of the formula in the equation \(\frac{mn}{a^2} - \frac{pq}{b^2} = 1\)
\(q = \frac{b^2(mn - a^2)}{a^2 p}\)
\(q = \frac{m^2 n - a^2}{p^2}\)
\(q = \frac{mn - 2b^2}{a^2}\)
\(q = \frac{b^2 (n^2 - ma^2)}{n}\)
Correct answer is A
\(\frac{mn}{a^2} - \frac{pq}{b^2} = 1\)
\(\frac{mn}{a^2} - 1 = \frac{pq}{b^2}\)
\(\frac{mn - a^2}{a^2} = \frac{pq}{b^2}\)
\(pq = \frac{b^2 (mn - a^2)}{a^2}\)
\(q = \frac{b^2(mn - a^2)}{a^2 p}\)
0 > x \(\geq\) -7
-7 \(\leq\) x < -1

90°
50°
45°
40°
Correct answer is D
< VSU = 90° (angle in a semi-circle)
\(\therefore\) < SUV = 180° - 90° - 50°
= 40°
< RSV = 40° (angle which chord makes tangent = angle in alternate segment)
