low pressure areas with diameters of over 500 miles. The barometric air pressure in inches of mercury at a distance of x miles from the eye of a severe hurricane is modeled by the formula f(x) = 0.48 ln (x + 1) + 27. (Source: A. Miller and R. Anthes, Meteorology) a. Evaluate f(0) and f(100). Interpret the result. b. At what distance from the eye of the hurricane is the air pressure 28 inches of mercury? 8.
