Question

the spread of a disease can be modeled as n equals 200 square root of t, where n is the number of infected people, and t is time (in days). how long will it take until the number of infected people reaches 1,400?

Answer 1

49 days

Explanation:

n = 200√t

1400 = 200√t

divide both sides by 200:

1400/200 = √t

7 = √t

square both sides:

t = 49

so 1400 will be infected after 49 days
