A building with a cost of $1,800,000 has an estimated residual value of $125,000, has an estimated useful life of 40 years, and is depreciated by the straight-line method. c. If at the start of the twenty-ninth year it is estimated that the remaining life is 5 years and that the residual value is $80,000, what is the depreciation expense for each of the remaining 5 years?

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.
