The sides of a nuclear power plant cooling tower form a hyperbola. The diameter of the bottom of the tower is 283 feet. The smallest diameter of the tower is 168 feet which is 415.5 feet above the ground. The tower is 537 feet tall. Find the width of the tower at a height of 46 feet.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
