Answer:
3.9125 × 10⁵² people
Step-by-step explanation:
A rumor starts with 3 people and the number of people who heard it doubles each day.
How many people would have heard the rumor after 20 days?
To calculate exponential growth, we use the formula:
[tex]y (t) = ae^{kt}[/tex]
where;
a = value at the start =3
k = growth rate = 2×3 = 6
t = time = 20 days
y(t) = value of the population at the given time (t) =??
[tex]y(t) = 3 \times e^{6\times 20}[/tex]
y(t) = 3.9125 × 10⁵² people
