Harris fabrics computes its predetermined overhead rate annually on the basis of direct labor-hours. at the beginning of the year, it estimated that 20,000 direct labor-hours would be required for the period’s estimated level of production. the company also estimated $94,000 of fixed manufacturing overhead expenses for the coming period and variable manufacturing overhead of $2.00 per direct labor-hour. harris'; s actual manufacturing overhead for the year was $123,900 and its actual total direct labor was 21,000 hours.

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.
