A contractor needs to build a ramp from the level ground up to a loading door that is 10 feet higher than the ground. By code, the angle of elevation can be no greater than 7°. a) How long must the ramp be if a 7° angle of elevation is used? Round to the nearest hundredth.

b) How far along the ground from the base of the door should the contractor begin building the ramp? Round to the nearest hundredth.

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.
