Answer 1

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

$\frac{0}{1} =\frac{2\pi }{b}$      $b=\frac{\pi }{5}$         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 ( $\frac{\pi }{5} x$)
