Evaluating the Six Trigonometric Functions Answers

The maximum height reached by the barnacleis m.

The minimum height reached by the barnacleis m.

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

d = ⇒ 1

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?

a = ,

The data from the previous table is plotted to the right. The distance the boat traveled is on the x-axis, and the vertical position of the barnacle is on the y-axis.The graph follows the pattern.

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

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

b = ,

This is the pattern for a function.

When the boat has traveled 10 meters, the height of the barnacle is approximately:

Gum’s maximum height: ft

b = ,

c =

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

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