Ahorse ran 800 meters in 40 seconds, 1200 meters in 60 seconds, and 480 meters in 24 seconds. is this a proportionality relationship? if so, what is the constant of proportionality? what does it represent? write an equation to represent the distance d, in meters, that the horse runs in t seconds.

Haruka hiked several kilometers in the morning. she hiked only 66 kilometers in the afternoon, which was 25% less than she had hiked in the morning. how many kilometers did haruka hike in all?

Is the point (0, 8) on the x-axis or y-axis? how do you know?

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.
