Question 863013: A. Find the capsize screening value for the Tartan 4100, which has a displacement of 23245 lbs. and a beam of 13.5 ft. using formula C = 4d^-1/3b
B. Solve this formula for d.
C. The graph shows C in terms of d for the Tartan 4100 (b=13.5). For what displacement is the sailboat safe for sailing?
I believed I solved A. I got 1.89, but totally confused at which direction to go next.

A. Find the capsize screening value for the Tartan 4100, which has a displacement of 23245 lbs. and a beam of 13.5 ft. using formula C = 4d^-1/3b
C = 4d%5E%28-1%2F3%29b
C = 4%2A23245%5E%28-1%2F3%29%2A13.5
C = 1.89 so that's right
B. Solve this formula for d.
4d%5E%28-1%2F3%29%2A13.5 = C
d%5E%28-1%2F3%29%2A54 = C
d%5E%28-1%2F3%29 = C%2F54
d = %28C%2F54%29%5E-3
d = %2854%2FC%29%5E3
:
We can check this, replace C with 1.89213
d = %2854%2F1.89213%29%5E3
d = 23245
C. The graph shows C in terms of d for the Tartan 4100 (b=13.5).
