you and a friend want to know how much rope you need to climb a large rock. your friend is 5.5 feet tall and casts a shadow
that is 18 feet long. if the rock casts a shadow that is 209.5 feet long, calculate the height of the rock from the ground. round
your answer to the nearest foot. (hint: make a drawing)
64 ft
18 ft
210 ft
219 ft

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.
