What do u do on this question

Evgen [1.6K]

If Terrence is skating at a constant rate then the answer to b would be it is a function. On a You say how close he is to the motion detector in feet during the second he says. Since the seconds is on the first one 0 then he is 0 feet. Then 2, 4, 6, 8. Because every second he gets to feet colser. On c, the independent variable is how time, and the dependent variable is distance from motion detector. The independent variable is what you change and the dependent variable changes because of the independent variable. Hope this helped!
