Answer:
Step-by-step explanation:
Originally, there were only five bacterial cells. After one month, the amount of bacteria is doubled with ten bacteria. The growth is represented by the formula:
a42 = 5 x 2^1
After 42 months, the growth can be solved using this formula:
a42 = 5 x 2^42 just so you know my cuz help me shes good in this
Answer:
[tex]N=2.1990232556 \times 10^{13}[/tex]
Step-by-step explanation:
Given : Brett has been studying a type of bacteria that doubles every month. Originally, there were 5 bacterial cells.
To Find: He wants to know how many there will be after 42 months?
Solution:
Since we are given that initially there were 5 bacterial cells.
Bacteria doubles every month
Let n denotes the number of months .
Function becomes : [tex]N=N_0(2)^n[/tex]
[tex]N_0[/tex] = initial amount
N = amount after n months
So, [tex]N=5(2)^n[/tex]
Substitute n = 42
[tex]N=5(2)^{42}[/tex]
[tex]N=2.1990232556 \times 10^{13}[/tex]
Thus there will be [tex]2.1990232556 \times 10^{13}[/tex] bacteria after 42 months.
