Penguins can swim at speeds of up to 33 feet per second. Use dimensional analysis to convert this speed to miles per hour. 1 mile = 5280 feet. (4 pts, 1 for feet into
miles, 1 seconds into hours, 1 simplified answer, 1 for units in answer.)

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

Ibelieve the answer is b. y=0 would make the line horizontal across the x.

The answer is 60.9774
