Answer/Step-by-step explanation:
Total Distance = 3Ft
a) Determine the amplitude and period of a sinusoidal function that models the bobbing buoy.
Amplitude = 3/2 = 1.5 period = 10 second
[tex]\frac{0}{1} =\frac{2\pi }{b}[/tex] [tex]b=\frac{\pi }{5}[/tex] No ph. Shift
b) Write an equation of a function that models the buoy with x=0 at its highest point.
y= 1.5 cos ( [tex]\frac{\pi }{5} x[/tex])
