The percentage of adult height attained by a girl who is x years old can be modeled by f ( x ) = 62 + 35 log ( x − 4 ) , where x represents the girl’s age (from 5 to 15) and f(x) represents the percentage of her adult height. Use the function to solve Exercises 113-114. Round answers to the nearest tenth of a percent. Approximately what percentage of her adult height has a girl attained at age ten? The bar graph shows the average number of hours per week that U.S. wives and husbands engaged in housework in six selected years. Use this information to solve Exercises 115-116.
