Misty is driving on a scenic road trip, and the graph shows the number of hours traveled compared to the number of miles of the trip remaining. Use the graph to answer 13-15.
13. Write an equation of the graph in slope-intercept form.
Yayi (*)
*2-XL (X-0)
200
MILES REMAINING
150
14. If Misty has been traveling for 9 hours, how many mile
of the trip does she have remaining
54 miles
15. If there are 50 miles in the trip remaining, how many
hours has Misty been traveling?
so
HOURS TRAVELED

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
