The power produced by a windmill varies directly with the square of its diameter and the cube of the wind speed. A fan with a diameter of 2.5 meters produces 600 watts of power if the wind speed is 4 m/s. How much power would a similar fan produce if it had a diameter of 4 meters and the wind speed was 5 m/s.
A. A system of three linear equations in three variables that has a unique solution can be represented by the point of intersection of three distinct planes.
B. A system of three linear equations in three variables that has a unique solution can be represented by a pair of lines that intersect a plane.
C. A system of three linear equations in three variables that has a unique solution can be represented by a common line that intersects three distinct planes.
D. A system of three linear equations in three variables that has a unique solution can be represented by the point of intersection of three distinct lines.
