HELP THIS IS DUE IN A COUPLE OF HOURS THE TYPE OF MATH IS ALGEBRA 1 HONORS

1. To begin a bacteria study, a Petri dish had 1500 bacteria cells. Each hour since, the number of cells has increased by 4.4%. Let t be the number of hours since the start of the study. Let y be the number of bacteria cells. Write an exponential function showing the relationship between y and t.

2. At the beginning of environmental study, forest covers an area of 1500km^2. Since then, this area has decreased by 7.9% each year. Let t be the number of years since the start of the study. Let y be the area that the forest covers in km^2. Write an exponential function showing the relationship between y and t.

3. At the beginning of a popular study, a city had 330,000 people. Each year since, the population has grown by 1.1%. Let T be the number of years since start of the study. Let Y be the cities population. Write an exponential function showing the relationship between Y and T.

4. A city has a population of 330,000 people. Suppose that each year the population grows by 5%. What will the population be after 6 years? Round your to the nearest whole number.

5. An amount of $39,000 is borrowed for 12 years at 8.5% interest compounded annually. If the loan is paid in time at the end of that period, how much must be paid back? Where are your answer to the nearest dollar.

6. A principle of $2900 is in invested at 4.25% interest, compounded annually. How much will the investment be worth it after 15 years? Round your answer to the nearest dollar.
