Current Attempt in Progress On February 14, 2007, paraglider Eva Wisnierska was caught in a freak thunderstorm over Australia and carried upward at a speed of about 3000 ft/min. The table below gives the temperature at various heights. Approximately how fast (in F/min) was her temperature decreasing when she was at 4000 feet? y (thousand ft) 2 4 6 8 10 12 14 16 H(F.) 75 67 53 46 38 31 24 17 O Estimates for the rate at which her temperature was decreasing range from 7 *F/ min to 21 *F/ min. O Estimates for the rate at which her temperature was decreasing range from 12 ' F/ min to 21 * F/ min. O Estimates for the rate at which her temperature was decreasing range from 4 *F/ min to 21 *F/ min. O Estimates for the rate at which her temperature was decreasing range from 17 * F/ min to 75 *F/ min. O Estimates for the rate at which her temperature was decreasing range from 17 *F/ min to 38 *F/ min.Coroners estimate time of death using the rule of thumb that a body cools about 20F during the first hour after death and about 10F for each additional hour. Assuming an air temperature of 68F and a living body temperatureof 98.6'F, the temperature T(t) in 'F of a body at a time t hours since death is given by T (1) = 68 + 30.6e-ki . (a) For what value of k will the body cool by 1.7F in the first hour? Round to three decimal places. (b) Using the value of k found in part (a), after how many hours will the temperature of the body be decreasing at a rate of 10'F per hour? Round to one decimal place.
