Annette’s shop teacher was discussing table saws. The teacher produced the following graph for a type of saw. The graph shows the height of one tooth on the circular blade relative to the cutting surface of the saw in terms of time.
What information about the table saw can Annette gather from the graph?
diameter?
axle depth?
(axis of curve)
speed?
