Here is the function for the number of zombies, N, after t years, with the negative exponent expressed using the fraction ½: N(t) = 300 • 0.5t/8

What is the half-life for the zombie population?

The half-life for the zombie population is of 8 years.

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

In which N(0) is the initial value and the part is related to the decay.

In this question:

Thus N(0) = 300, that is, initial population of 300.

What is the half-life for the zombie population?

This is t for which N(t) = 0.5*300 = 150. So

Equal exponents, so:

The half-life for the zombie population is of 8 years.
