Consider regular pentagons with side length s, area a, and perimeter p. Suppose f, g, h, and j are functions such that: f(s) represents the perimeter (in cm) of a regular pentagon whose side length is s cm. g(p) represents the side length (in cm) of a regular pentagon whose perimeter is p cm. h(s) represents the area (in cm2) of a regular pentagon whose side length is s cm. j(a) represents the side length (in cm) of a regular pentagon whose area is a cm2. Use function notation (with the appropriate functions above) to represent the area of a regular pentagon whose perimeter is 120 cm.   Use function notation (with the appropriate functions above) to represent the perimeter of a regular pentagon whose area is 5.16 cm2.

Question

Consider regular pentagons with side length s, area a, and perimeter p. Suppose f, g, h, and j are functions such that:

  • f(s) represents the perimeter (in cm) of a regular pentagon whose side length is s cm.
  • g(p) represents the side length (in cm) of a regular pentagon whose perimeter is p cm.
  • h(s) represents the area (in cm2) of a regular pentagon whose side length is s cm.
  • j(a) represents the side length (in cm) of a regular pentagon whose area is a cm2.
  1. Use function notation (with the appropriate functions above) to represent the area of a regular pentagon whose perimeter is 120 cm.

     

  2. Use function notation (with the appropriate functions above) to represent the perimeter of a regular pentagon whose area is 5.16 cm2.
