Technetium-99m, a radioisotope used to image the skeleton and the heart muscle, has a half-life of about 6 hours. find the decay constant. use the decay function n(t)=n0e−kt to determine the amount of a 250 mg dose that remains after 24 hours. 16 mg  or 63 mg or 125 mg or 3998 mg plz show how to solve the equations

Which two undefined geometric terms always describe figures with no beginning or end?

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.
