Here is the equation that models this:
^The y-coordinates are in m and the x coordinates is the time in seconds

b) Use the model to determine when, during each cycle, the boat is 0.5m above the mean positition.

-12.25

Step-by-step explanation:

To solve the expression, plug in -0.25 as x and plug in -6 as y

x + 2y

-0.25 + 2(-6)

-0.25 - 12

= -12.25

So, the solution is -12.25
