Strain B started with a genetic mutation in patient zero that caused them to turn into a zombie. This strain differs from A in that all zombies can infect new people. Zombies infected with strain B can infect 1 person every minute.
Using the CDC Virus Information, determine which type of graph for STRAIN B and write an equation to show the number of zombies after each minute.
Based on the given information, the most suitable type of graph to represent the spread of STRAIN B would be an exponential growth graph.
To write an equation for the number of zombies after each minute, we can use the following formula for exponential growth:
N = N₀ * (1 + r)^t
Where:
N = the number of zombies after t minutes
N₀ = the initial number of zombies (in this case, patient zero)
r = the growth rate (in this case, the infection rate of 1 person per minute)
t = the time in minutes
Since patient zero is the first infected zombie, the initial number of zombies (N₀) would be 1. Therefore, the equation for the number of zombies after each minute for STRAIN B would be:
N = 1 * (1 + 1)^t
Simplified equation:
N = 2^t
