A table fan has a mark on the tip of one blade. The equation y = 16 sin (4xx) + 23 represents the height of the mark, y centimetres, above the table x seconds after the fan is turned on. What is the distance from the mark to the tip of the opposite blade? Hint: If you draw a horizontal line through the center, from tip to tip, how long is the line?
