Peggy has been studying a type of bacteria that triples every month. Originally, there were 2 bacterial cells. She wants to know how many there will be after 24 months. Which equation should she use?

Respuesta :

Let [tex]u_n[/tex] represent the number of bacteria after n months.

[tex]u_0=2[/tex] is the original number of bacteria

[tex]u_1=2*3=6[/tex]

[tex]u_2=2*3*3[/tex]

[tex]u_3=2*3*3*3[/tex]

so it is clear that :

[tex]u_n=2* 3^{n} [/tex]

After 24 months, there will be [tex]u_2_4=2* 3^{24} [/tex] many bacteria.


Answer: 

the equation:
[tex]u_n=2* 3^{n} [/tex], where u_n is the number of bacteria after n months,

[tex]u_2_4=2* 3^{24} [/tex]
