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.

part 3 of the question is:
A power outage occurs 6 min after the ride started. Passengers must wait for their cage to be manually cranked into the lowest position in order to exit the ride. Sine function model: where h is the height of the last passenger above the ground measured in feet and t is the time of operation of the ride in minutes.
What is the height of the last passenger at the moment of the power outage? Verify your answer by evaluating the sine function model.
Will the last passenger to board the ride need to wait in order to exit the ride? Explain.
2. The duration of the ride is 15 min.
(a) How many times does the last passenger who boarded the ride make a complete loop on the Ferris
wheel?
(b) What is the position of that passenger when the ride ends?
