Question 199143This question is from textbook
: 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 formula
S = 16Ad-2/3.(-2/3 is the power or exponent whatever they want to call it)
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.
b) Write d in terms of A and S.

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 formula
:
S = 16A%28d%5E%28-2%2F3%29%29
:
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%2A810%2823245%5E%28-2%2F3%29%29
S = 12960 * .00122776
S = 15.9 knots
:
b) Write d in terms of A and S.
16A%28d%5E%28-2%2F3%29%29 = S
:
d%5E%28-2%2F3%29 = S%2F%2816A%29
:
d = %28S%2F%2816A%29%29%5E%28-3%2F2%29
