At time 0s, a population has 2 members. at time 2s, there are 4 members. at time 6s, there are 16 members. what type of growth is being experienced by this population?

Exponential growth is seen

Given that initial population, at time 0 members =2

i.e. P0 =2

P(2) = 4

In 2 minutes it became 4 times

And in 6 minutes it became 16 members

P(0) =2

P(2) =4

P(6) =16

i.e. every 2 minutes the population doubles

Hence exponential growth of population doubling in 2 minutes

P(t) =

will be the function representing the population at time t.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
