Polar bears are listed as a threatened species. In 2005, there were about 25,000 polar bears in the world. If the number of polar bears declines by 1000 each year, in what year will polar bears become extinct?(2 points)

Question

Polar bears are listed as a threatened species. In 2005, there were about 25,000 polar bears in the world. If the number of polar bears declines by 1000 each year, in what year will polar bears become extinct?(2 points)

a.) What equation models the number of polar bears?

How can graphing the equation help you solve the problem?

Answer 1

The equation that models the number of polar bears is:

Number of polar bears = 25,000 - 1000 * t

In this equation, t represents the number of years since 2005.

Graphing the equation can help solve the problem because it allows us to visually see the trend in the decline of the polar bear population over time. By plotting the equation on a graph, we can determine the year when the number of polar bears becomes zero, indicating their extinction.
