# Project #8158 - real world radical formulas

To be considered safe for ocean sailing, the capsize screening value C should be less than 2. For a boat with a beam or width b in feet and dispalcement d in pounds, C is determined by the function. C=4d^-1/3b.

a. find the capsize screning value for the Tartan 4100, which has a displacement of 23,245 pounds and a beam of 13.5 feet.

b. solve for d. (Formula: 1.1g^-1/4H.)

The sail-area displacement ratio Sprovides a measure of the sail power available to drive a boat. For a boat with the displacement of d pounds and a sail area of A suare feet S is determied by the function S=16AD^-2/3

a. finf the 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.

b. write d in terms of A and S
