Answer:

  • p = 18 / √d
  • d = 81

Step-by-step explanation:

p varies inversely as a square roots of d:

  • p = k / √d

p equals 6 when d equals 9:

  • p = 6, if q = 9
  • 6 = k / √9
  • 6 = k / 3
  • k = 18

The equation is:

  • p = 18 / √d

Find d when p = 2:

  • 2 = 18 / √d
  • √d = 18/2
  • √d = 9
  • d = 9²
  • d = 81
