Respuesta :

Answer:

[tex]P(t)=37\cdot 4^{t/9.1}[/tex]

Step-by-step explanation:

The number of people who receive the email increases by a factor of 4 every 9.1 weeks.

This is an exponential growth of the form:

[tex]A=A_o(r)^{t/k}[/tex]

Where:

[tex]A_o =$Initial value\\r=Growth rate\\k=Growth Period\\t=time[/tex]

In this case:

[tex]A_o =37\\r=4\\k=9.1\:weeks[/tex]

Therefore at any time t, the function describing this scenario is:

[tex]P(t)=37\cdot 4^{t/9.1}[/tex] where t is in weeks.
