**Unformatted text preview: **C = 64b^3 C^-3/(4b)^-3 = (c/4b)^-3 = d 1. Sailboat speed. The sail area-displacement ratio S provides a measure of the sail power available to drive a boat. For a boat with a displacement of d pounds and a sail area of A square feet S is determined by the function a) Find S to the nearest tenth for the Tartan 4100, which has a sail area of 810 square feet and a displacement of 23,245 pounds. S=16(810)(23,245)^(-2/3) multiplied S=12960(0.0012) S=15.55 b ) Write d in terms of A and S . S/16a = 16a/16a d^-23 (S/16a)^-2/3 (d^-2/3) ^-2/3 both side divide by 16a (16a)^2/3/(s) ^2/3 = d now d is place on the right hand side for the final answer...
