We are given that, a computer can sort x objects in t seconds, and the below relations is satisfied for each x and t

  • t = 0.003 x² + 0.001 x

For 12 objects, we can substitute x = 12

⇒ t = (3/1000) (12)² + (1/1000) 12

⇒ t = (12/1000) (3 × 12 + 1)

⇒ t = (12×37/1000)

⇒ t = 444/1000

⇒ t = 0.444

⇒ t ≈ 0.40 seconds (2 dp)
