Foot traffic at the Susquehanna River is decreasing at a rate of y = −3x + 90 people per hour until it levels off at 18 people per hour. Write the piecewise equation for this situation and find
how many people are at Harper’s Ferry after:
12. 10 hours
13. 28 hours

-2 is the right

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
