Suppose the annual sales (in billions of dollars ) of a corporation from 2004 through 2009 can be approximated by the linear equation S = 2.925t - 1.51; 4 <= t <= 9 where represents the year, with t = 4 corresponding to 2004. Use the model to estimate the year in which the corporation's annual sales were about $14 billion. (Round your answer to nearest year. )

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.
