11. the designers of sport shoes assume that the force exerted on the soles of shoes in a
jump shot is proportional to the weight of the person jumping. a 140-pound athlete
exerts a force of 1960 pounds on his shoe soles when he returns to the court floor after
a jump. determine the force that a 270-pound professional basketball player exerts on
the soles of his shoes when he returns to the court floor after shooting a jump shot.

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.
