the
population P (in thousands) of a certain city from 2000 through
2008 can be modeled by
p=280.84e^kt
where t is the year with t=0
corresponding to 2000.
in 2006 the population was about 360,000.
(a) finf the value of k for the model. round your result to
four decimal places

can someone help me with this please thanks U
can someone help me with this please thanks U.S. Population YEAR POPULATION 1930 122,800,000 1940 131,700,000 1950 150,700,000 1960 179,300,000 It is estimated that the limiting population that the United States can support is 500,000,000 people. Predict the population for the year 2000 using the logistic growth model on the basis of the data in the years 1950 and 1960. In other words: * Let P = P (t) be the population, where t is the number of years after...
