Question: DEATH DUE TO STROKES Before 1950 little was known about strokes. By 1960, however, risk factors such as hypertension were identified. In recent years, CAT scans used as a diagnostic tool have helped prevent strokes. As a result, death due to strokes have fallen dramatically. The function
N(t) = 130.7e-0.1155t2 + 50 (0 ≤ t ≤ 6)
gives the number of deaths per 100,000 people from 1950 through 2010, where t is measured in decades, with t = 0 corresponding to 1950.
a. How many deaths due to strokes per 100,000 people were there in 1950?
b. How fast was the number of deaths due to strokes per 100,000 people changing in 1950? In 1960? In 1970? In 1980?
c. If the trend continues, how many deaths due to strokes per 100,000 people will there be in 2010?
