Cool Down

The equation p=5,000·2tp=5,000·2t represents the population of an invasive fish species in a large lake, tt years since 2005, when the fish population in the lake was first surveyed. Use the '^' symbol to enter an exponent.

1.

What was the population in 2005?

2.

What is this value of the population in 2005 in scientific notation?

3.

For this model, what does it mean when tt is –2?

4.

For t=−2t=−2, is the fish population more or less than 1,000? How do you know?

5.

Write the value of the fish population when t=−2t=−2 in scientific notation.
