Its distance D(t) (in m) from the floor of the lake as a function of time t (in seconds) can be modeled by a
sinusoidal expression of the form a .sin(b. t) + d.
Att = 0, when the boat is exactly in the middle of its oscillation, it is 1 m above the water's floor. The boat
reaches its maximum height of 1.2 m after 5 seconds.
Find D(t).
t should be in radians.
D(t) =

Mason and christian go to the movie theater and purchase refreshments for their friends. mason spends a total of $45.75 on 3 bags of popcorn and 6 drinks. christian spends a total of $71.50 on 6 bags of popcorn and 4 drinks. write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. using these equations, determine and state the price of a drink, to the nearest cent.
