Kahleela starts the engine on her small private airplane. the engine drives a propeller with a radius of 8.5 feet and its centerline 11.5 feet above the ground. at idle, the propeller rotates at a constant speed of approximately 800 revolutions per minute. the height of one propeller tip as a function of time is given by h = 11.5 + 8.5 sin(800t), where h is the height in feet and t is the time in minutes. find h when t = 5.5 minutes. a. 3.1 ft b. 13 ft c. 19.9 ft d. 10 ft

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
