C=2rπ for r relates the circumference Cof a circle to its radius r. (Recall that is the constant ratio of circumference to diameter.) a. Solve C= 2 r for r. b. If a circle's circumference is 15 inches, what is its radius? Leave the symbol in your answer.

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.

The population of a bacteria colony grows by a consistent percentage each hour and can be modeled by the function y = 500(1.16)t. what does the value 500 represent in the function?

Use the equation and type the ordered-pairs. y = 2 ^x
