Question

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? Explain in terms of exponents

Answer 1

t must be 8 years.
I literally googled it.

Answer 2

Eight years. To get ½ of the 300, you need 0.5^(t/8) to equal ½, or 0.5. That means that the exponent must be 1. This happens when t = 8 years.
