In 1989, research scientists published a model for predicting the cumulative number of aids cases reported in the united states: a(t) = 155 t − 1980 10 3 , (thousands) where t is the year. this paper was considered a "relief," since there was a fear the correct model would be of exponential type. use the two data points predicted by the research model a(t) for the years 1985 and 1995 to construct a new exponential model b(t) for the number of cumulative aids cases. (round values to three decimal places.) b(t) = incorrect: your answer is incorrect.
