2. a rock is dropped from the edge of a 180 m
cliff. the function h(t) = -522 – 5t + 180
gives the approximate height of the rock, h(t),
in metres t seconds after it was released. how
long does it take for the rock to reach a ledge
80 m above the base of the cliff?

The dash figure is a dilation if the original figure. find the scale factor. classify the dilation as an enlargement or a reduction

Aline has a slope of . which ordered pairs could be points on a parallel line? check all that apply. (-8, 8) and (2, 2) (-5, -1) and (0, 2) (-3, 6) and (6, -9) (-2, 1) and (3,-2) (0, 2) and (5,5)

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.
