Graphing Sine and Cosine Answers

How far does the barnacle travel in one revolution of the water wheel? m

b = ,

c =

d = ,

The boat is traveling at a rate of 1 meter per second.How long does it take the barnacle to get back to its starting point?

The amplitude is . The vertical shift is . An equation for this graph is y = .

Graph y = sin(x) on the graphing calculator. Use the graph to determine the height of the barnacle with respect to water level as the boat has traveled the given distance.When the boat has traveled 7 meters, the height of the barnacle is approximately:

Find the following (take ground level to be 0):Gum’s minimum height: ft Gum’s maximum height: ft

How far does the gum travel in one revolution of the bicycle wheel? ft

a = [___], b = [___], c = [___], d = [___], e = [___]

The maximum height reached by the barnacleis m.

The minimum height reached by the barnacleis m.
