In a lab, 370 cells are present at the beginning of an experiment. During the first 9 hours, the number of cells increased by 10% each hour. Write an exponential model giving the number of cells y present t hours after starting the experiment. Estimate the time when the number of cells is 600. y = 370(0.1)*; after about 10 hours y = 370(0.9)'; after about 0.5 hour y = 370(1.1)'; after about 5 hours O y = (370 • 1.1)' ; after about 1 hour

Wildlife biologists need to estimate the number of small mouth bass in a lake. After netting, a total of 33 small mouth bass were captured, tagged and released back into the lake. A week later, another netting resulted in the capture of 78 small mouth bass, 11 with tags. Which estimate below best represents the total amount of small mouth bass that are in the lake (round to the nearest whole number fish)? O 433 O 251
