Answer:
Step-by-step explanation:
<u>Exponential Growth </u>
When the number of observed elements grows as the previous value multiplied by a constant ratio, we have exponential growth. The formula to model such situations is
Where is the initial value of f, 1 + r is the constant ratio, and t is the time expressed in half days (12 hours)
The initial value is 100 Instant followers, thus:
We need to know when the number of followers will reach 1,000,000. Setting up the equation
Simplifying by 100
Taking logarithms
Solving for t
periods of 12 hrs
