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? enter your answer in the box.

The smokey mountains have over 2,100 miles of rushing mountain streams and rivers that flow through the park. in each mile lives a diverse community of native fish, amphibians, insects, and larvae, some of which are found only in the southern appalachians. park managers and scientific researchers test many factors such as fish populations, the watersheds and water tests to determine a) too many lizards are present b) the water quality of the stream c) rainwater is running into local streams d) if visitors to the park are overstaying their welcome
