The populations P (in thousands) of a certain town in North Carolina, from 2006 through 2012 can be modeled by P = 5.5e^kt,
where t is the year, with
t = 6
corresponding to 2006. In 2008, the population was 7000.

Find the value of k for the model. Round your result to four decimal places.

Use your model to predict the population in 2018. (Round your answer to the nearest person.)

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
