Find a formula in each part below for the number of zebra mussels in a bay as a function of the number of years since 2014, given that there were 2700 at the start of 2014L and 3159 at the start of 2015. NOTE: Enter the sweet answers. Let 1; represent the number of zebra mussels it years since 2014. (a) Assume that the number of zebra mussels is growing linearly. Give units for the slope of the line and interpret it in terms of zebra mussels. The slope of the line is |:| and represents (b) Assume that the number of zebra mussels is growing exponentially. Expmem some y = |:| 1What is the annual percent growth rate of the zebra mussel population? |:| % per year- V IIIIIIIIIIII Current Attempt in Progress 'Whooping cough was thought to have been almost wiped out by vaccinations. It is now known that the vaccination wears o} 1 leading to an increase in the number of cases, to, from 1248 in 1981 to 25,827 in 2004. (a) With t in years since 1980, nd an exponential function that ts this data. NOTE: Round numbers to three decimal places if necessary. (b) What does your answer to part (a) give as the average annual percent growth rate of the number of cases? NOTE: Round your answer to the nearest percent. The annual percent gowth rate is |:| % (c) On May 4, 2005, the Arizona Daily Star newspaper reported (correctly) that the number of cases had more than doubled between 2000 and 2004.
