The displacement of a swinging ball in simple harmonic motion is modeled by the equation d=8sin(16t), where t is measured in seconds. If d is measured in centimeters, what is the displacement to the nearest centimeter when t=12?

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
