3.7 Sinusoidal Function Context and Data Modeling - Review
A coastal town records the height of the tide every hour over a 24-hour period. The data shows that the tide height varies sinusoidally with a maximum height of 10 feet and a minimum height of 2 feet. The tide reaches its maximum height at 6 AM and its minimum height at 6 PM. Write a sinusoidal function that models the tide height as a function of time.
A Ferris wheel has a diameter of 50 meters and completes one full rotation every 5 minutes. The lowest point of the Ferris wheel is 2 meters above the ground. Write a sinusoidal function that models the height of a passenger above the ground as a function of time.
The average monthly temperature in a city varies sinusoidally over the year, with a maximum of 30°C in July and a minimum of -10°C in January. Write a sinusoidal function that models the average monthly temperature as a function of time, where
A population of rabbits in a forest varies sinusoidally with a maximum population of 500 rabbits in April and a minimum population of 100 rabbits in October. Write a sinusoidal function that models the rabbit population as a function of time, where
The daylight hours in a city vary sinusoidally throughout the year, with a maximum of 15 hours in June and a minimum of 9 hours in December. Write a sinusoidal function that models the number of daylight hours as a function of time, where
Given the data points representing the average monthly temperatures in a city over a year, describe the steps you would take to fit a sinusoidal model to this data.

OpenClass is on a mission to improve & democratize education. Through our platform, educators can share assignments privately or with our entire community to improve accessibility of the best learning resources around the world.
Our assignments guide students through research-backed study sessions to reinforce learning. If this review is relevant to your teachings, feel free to add it to one of your classes!
Our format is simple and engaging: students are asked a retrieval question, then shown corrective feedback and a multiple-choice mastery question to assess their understanding of the material. Assignments adapt to unique student needs and continue to draw questions until a student has demonstrated mastery.
