- An object moves in simple harmonic motion with period 8 seconds and amplitude 2 cm. At time t=0 seconds, its displacement d from rest is -2 cm, and initially it moves in a positive direction. Give the equation modeling the displacement d as a function of time t.arrow_forwardAccording to data from the Hill AerospaceMuse um (Hill Air Force Base, Utah), the speed of sound varies depending on altitude, barometric pressure, and temperature. For example, at 20,000 feet, 13.75 inches ofmercury, and - 12.3°F, the speed of sound is about 707 miles per hour, but the speed can vary from this result by as much as 55 miles per hour as conditions change.(a) Express this situation as an inequality involving an absolute value.(b) Using x for the speed of sound, solve for x to find an interval for the speed of sound.arrow_forwardA ferris wheel has a radius of 28 feet and completes 3 revolution in 1.5 minutes. Assume the nder begins at the lowest point of the wheel, 2 feet above ground level. Model the height of the rider, in feet above the ground, as a function of time in seconds, using a sine equation with only positive numbers in the final equation.arrow_forward

Its center is 31 m above the ground. It rotates once every 40 s. Suppose you get on the bottom at t = 0. Write an equation that expresses your height as a function of elapsed time. Oh = 31 cos 2T- - O h = 30 cos 2T (t - 40) 40 = (t - 20) 40 Oh 31 cos 2T- = (t - 20) 40 (t – 20) 40 Oh 30 cos 2π- 2T +30 +1 +30 +31arrow_forward
- A Ferris wheel at a local fair has a diameter of 66 m and the maximum height above the ground reached by a seat is 72 m. When discussing the graph of a sinusoidal function that models the height of the seat above the ground during the ride, the minimum value is The median value is The amplitude isarrow_forward7. The number of visible sun spots varies rhythmically from 10 to 110 per year over a period of eleven years. The 110 max last occurred in the year 2014. a.) b.) Write a sinusoidal function N (t) to model that number of sun spots per year, where t is in years past the year 2014. What number of sun spots does your function predict for the year 2018?arrow_forwardExplain the Secant function.arrow_forward
