Julie is a math tutor. she charges each student $210 for the first 7 hours of tutoring and $20 for each additional hour. when the number of hours (h) that julie spends tutoring a student is greater than 7 (h > 7), the equation that gives the amount (a) that julie earns in dollars is a = 210 + 20(h + 7) a = 210 + 20(h - 7) a = -210 + 20(h - 7) a = 210 + (h - 7)/20. if julie earns $410 tutoring one student, solve for the total number of hours she spent tutoring the student.
a.) 38
b.) 19
c.) 17
d.) 12

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.
