Let’s check out your problem:

c=(4b)/(root(3)(d))
The formula gives the capsize screening value, 
c, for a sailboat with a beam 
b feet long and that displaces 
d pounds of water. Higher capsize screening values suggest that a sailboat is more stable. Which of the following equations correctly gives the displacement in terms of the capsize screening value and the beam length?
Choose 1 answer:
(A) 
d=((4b)^(3))/(c)
(B) 
d=(c^(3))/(4b)

Q. c=4bd3c = \frac{4b}{\sqrt[3]d}\newlineThe formula gives the capsize screening value, cc, for a sailboat with a beam bb feet long and that displaces dd pounds of water. Higher capsize screening values suggest that a sailboat is more stable. Which of the following equations correctly gives the displacement in terms of the capsize screening value and the beam length?\newlineChoose 11 answer:\newline(A) d=(4bc)3d=\left(\frac{4b}{c}\right)^3\newline(B) d=c34bd=\frac{c^3}{4b}\newline(C) d=(4bc)3d=\left(\frac{4b}{c}\right)^3\newline(D) d=(c4b)3d=\left(\frac{c}{4b}\right)^3
  1. Given Equation: The original equation is given by c=4bd3c = \frac{4b}{\sqrt[3]{d}}. We want to solve for dd in terms of cc and bb.
  2. Isolate Term with dd: First, we will isolate the term containing dd on one side of the equation by multiplying both sides by d3\sqrt[3]{d}. This gives us cd3=4bc \cdot \sqrt[3]{d} = 4b.
  3. Divide by cc: Next, we divide both sides of the equation by cc to get d3=4bc\sqrt[3]{d} = \frac{4b}{c}.
  4. Get Rid of Cube Root: To solve for dd, we need to get rid of the cube root. We do this by raising both sides of the equation to the power of 33, which gives us d=(4bc)3d = \left(\frac{4b}{c}\right)^3.
  5. Final Equation Comparison: Comparing the result with the given options, we find that the correct equation is (C) d=(4bc)3d = \left(\frac{4b}{c}\right)^3.
