JAMB Mathematics 1986 Question 27

Question 27

Algebraic Expressions

Make v the subject of the formula s = √(6/v − w/2)

  1. A.v = 6/s2 + 12/w
  2. B.v = 12/(2s2 − w)
  3. C.v = 12/w − 2s2
  4. D.v = 12/(2s2 + w)
Show the answer and explanation

Answer: D (v = 12/(2s2 + w))

Explanation

Square: s² = 6/v − w/2, so 6/v = (2s² + w)/2 and v = 12/(2s² + w).
