Question

1. Meteorologists can determine the duration of a storm by using the function defined by T(D)=0.07D3/2, where D is the diameter of the storm in miles and T is the time in hours. Find the duration of a storm with a diameter of 16 mi. Round your answer to the nearest tenth of an hour.



2. The threshold weight T, in pounds, for a person is the weight above which the risk of death increases greatly. The threshold weight in pounds for men aged 40 – 49 is related to height h in inches by the function defined by h(T)=(1860.867T)1/3 What height corresponds to a threshold weight of 200 lb for a 46 yr – old man? Round your answer to the nearest inch and then to the nearest tenth of a foot.

Answer 1

#2. The T's cancel. So; h=1860.867/3=620.289. Where is "age" applied?
