the total recommended area A, in square feet, of a sailboat's sails is given by [{MathJax fullWidth='false' A = 16\sqrt[3]{d^2} }] where d is the displacement of the hull in cubic feet. If a sailboat has 400 ft² of sail, what is the displacement of the hull of the sailboat?

125ft³

Step-by-step explanation

Given the area of the sail boat expressed as . IF the area is 400ft², we are to find the displacement d;

Substitute A = 400 into the expression given and find d as shown;

Hence the displacement of the hull of the sailboat is 125ft³

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
