a is the length of the bladeheight of the windmillnumber of rotations per minute.
Which periodic function, sine or cosine, would be a simpler model for the situation? Explain.
A cosine function would be a simpler model for the situation. The minimum depth (low tide) occurs at t = 0, so a reflection of the cosine curve has a minimum there. A sine model would require a phase shift, while a cosine model does not.
This amplitude is [___] meters. a = [___]
1.5; -1.5
The graph of these points follows a path resembling a .
On a coordinate plane, a curve starts at (0, 10). It has a maximum of y = 16 and a minimum of y = negative 2.5. On a coordinate plane, a curve starts at (0, 10). It has a maximum of y = 18 and a minimum of y = 4. On a coordinate plane, a curve starts at (0, 10). It has a maximum of y = 15 and a minimum of y = 8. On a coordinate plane, a curve starts at (0, 10). It has a maximum of y = 18 and a minimum of y = 4.
The vertical shift, k, is the length of the bladeheight of the windmillnumber of rotations per minute.
Which did you include in your response
This amplitude is [___] meters. a = [___]
1.5; -1.5
The phase shift is h = -2-112
so a = .
-30
