Final answer:
The number of deaths from AIDS in the US in 2007, if the trend of exponential growth continued unchecked, would have been approximately 68,626 people.
Step-by-step explanation:
The question asks how many people would have died from AIDS in 2007 if the trend of exponential growth continued unchecked. In 1933, about 1,700 people in the US died of AIDS. To find the number of deaths in 2007, we can use the exponential growth model with a growth factor of 1.9. We can calculate the number of deaths as follows:
Number of deaths in 2007 = Number of deaths in 1933 * (growth factor)(2007-1933)
Number of deaths in 2007 = 1,700 * (1.9)(2007-1933)
Calculating this, we find that approximately 68,626 people would have died from AIDS in the US in 2007 if the trend had continued unchecked.
