Question

Scientists can estimate the number of bacteria in a refrigerated food using the formula 0.26=

Answer 1

Time is C. 50 seconds

Step-by-step explanation:

The population of bacteria at time t here is given by

$0.2b=\frac{t^2}{20}$

where

b is the number of bacteria

t is the time in seconds

Here we want to find the approximate time at which the number of bacteria is

b = 625

Substituting into the equation and solving for t, we find:

$t^2=20\cdot 0.2 b\\t=\sqrt{4b}=\sqrt{4\cdot 625}=50 s$

Therefore, the solution is

C. 50 seconds
