Question 296057: Honestly I do not know where to begin with this question I am really stuck,
Since 1988 basic yacht dimensions for the America�s cup competition have satisfied the inequality
L+1.25√S-9.8^3√D≤16.296
NOTE- after the 9.8 the cubed is above the square root not the 8
Where L is the boat�s length in meters (m), S is the sail area in square meters, and D is the displacement in cubic meters. A team of naval architects is planning to build a boat with a displacement of 21.44 cubic meters (m^3), a sail area of 320.13 square meters (m^2) and a length of 21.22 m. Does this boat satisfy the inequality? If the length and displacement of this boat cannot be changed, then how many square meters of sail area must be removed so that the
boat satisfies the inequality?

Question 297226: 1. Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on Earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation: w=Cr^-2, where C is a constant, and r is the distance that the object is from the center of Earth.
b. Suppose that an object is 100 pounds when it is at sea level. Find the value of C that makes the equation true. (Sea level is 3,963 miles from the center of the Earth.)
I am confused about how do to the question.
