Question: INTERNATIONAL AMERICA'S CUP CLASS Drafted by an international committee in 1989, the rules for the new International America's Cup Class (IACC) include a formula that governs the basic yacht dimensions. The formula
f(L, S, D) ≤ 42
Where
f(L, S, D) = (L + 1.25S1/2 - 9.80D1/3)/0.388
Balances the rated length L (in meters), the rated sail area S (in square meters), and the displacement D (in cubic meters). All changes in the basic dimensions are trade-offs. For example, if you want to pick up speed by increasing the sail area, you must pay for it by decreasing the length or increasing the displacement, both of which slow down the boat. Show that yacht A of rated length 20.95 m, rated sail area 277.3 m2, and displacement 17.56 m3 and the longer and heavier yacht B with L = 21.87, S = 311.78, and D = 22.48 both satisfy the formula.
