Sailors use the following quadratic function to estimate wave height h, in feet, from wind speed w, in miles per hour: h = 0.02w2. (a) What wave height does the formula give for a wind speed of 25 miles per hour? b) A sailor observes that the wave height is 4 feet. According to the formula above, what is the speed of the wind? (Round your answer to two decimal places.)
