What formula would you use to calculate the mass of fermium-253 remaining after d days? f(d)=400(0.833)d f(d)=400(0.794)d f(d)=400(0.500)d f(d)=400(0.100)d

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
