Atrain slows down as it rounds a sharp horizontal turn, going from 92.0 km/h to 54.0 km/h in the 16.0 s that it takes to round the bend. the radius of the curve is 130 m. compute the acceleration at the moment the train speed reaches 54.0 km/h. assume the train continues to slow down at this time at the same rate.

Find the distance between the pair of points a(-1,8) and b(-8,4)

Three students, javier, sam, and corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. each student also had some initial donations that were collected before the run. the equations that represent each student's total donation, y, based on the number of laps ran, x, is shown below. match each equation with the correct rate of change for that student.
