1. A new town doubles in population every 3 years. Its population is modelled by the equation P = 1000(2), where t is the number of years since the town's founding. How long will it take the population to reach 8000?

Does a linear, exponential, or logarithmic model best fit the data in Table 2? Find the model.

Suppose that $12,000 is invested in a saving account paying 5.6% interest per year. (a)Write the formula for the amount in the account after t years if interest is compounded monthly. (b)Find the amount in the after 3 years if interest is compounded daily. (c)How long will it take for the amount in the account to grow to $20,000 if interest iscompounded continuously?
