50 pts a cyclist travels at distance of 400 meters in 120 seconds towards school, calculate his speed. (show your work) calculate his velocity if the direction is north east (ne) the cyclist in practice question 2, comes to a stop position within 15 seconds. calculate his acceleration. (show your work) is this an example of positive or negative acceleration?

What is the total area of the figure?

Solve -.016x= -16. need solving this

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.
