A winch at the top of a 12-meter building pulls a pipe of the same length to a vertical position, as shown in the figure. The winch pulls in rope at a rate of -0.6 meter per second (ds/dt = -0.6 m/sec). Find the rate of vertical change and the rate of horizontal change at the end of the pipe when y - 4. (Round your answers to three decimal places.)

horizontal m/sec

vertical m/sec

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.
