The population of a particular country was 28 million in 1985; in 1990, it was 36 million. the exponential growth function a=28e^{kt} describes the population of this country t years after 1985. use the fact that 5 years after 1985 the population increased by 8 million to find k to three decimal places.

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
