7) ted has $6.80 in quarters and dimes. the
number of quarters is 3 times the number of
dimes. use the system of equations can be used
to find q, the number of quarters, and d, the
number of dimes, that ted has.

q= 3d
0.259 + 0.10d = 6.80

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.
