Question 1077993: 1. Over a 24-hour period, the tide in a harbor can be modeled by one period of a sinusoidal function. The tide measures 4.35 ft at midnight, rises to a high of 8.3 ft, falls to a low of 0.4 ft, and then rises to 4.35 ft by the next midnight.

What is the equation for the sine function f(x), where x represents time in hours since the beginning of the 24-hour period, that models the situation?
2. The table of values shows the height of a car of a Ferris wheel as it travels in a circular motion.
Time (seconds) Height (meters)
0 6
2 26
4 46
6 26
8 6
10 26
12 46
14 26
16 6

Which statements are true? choose all that apply
The radius of the Ferris wheel is 26 m.
The car makes a complete revolution in 8 s.
If the car is loaded at 0 s, then people are loaded at the lowest height of the Ferris wheel.
The maximum height of the Ferris wheel above ground is 40 m.
