Answer:
4x=y
Step-by-step explanation:
4x=y is your answer because if x is 5, like in the table, then 4(5) would equal 20, which is the y-value. It also works for every number in the table.
Hope this helps.
The population after 20 weeks will be 403.42
in which
is the initial population.
Given that the growth rate of bacteria at any time t is proportional to the number present at t and triples in 1 week.
We are required to find the number of bacteria present after 10 weeks.
let the number of bacteria present at t is x.
So,
dx/dt∝x
dx/dt=kx
1/x dx=k dt
Now integrate both sides.
=
log x=kt+log c----------1
Put t=0
log
=0 +log c (
shows the population in beginning)
Cancelling log from both sides.
c=
So put c=
in 1
log x=kt+log 
log x=log
+log 
log x=log 
x=
We have been given that the population triples in a week so we have to put the value of x=2
and t=1 to get the value of k.
2
=
2=
log 2=k
We have to now put the value of t=20 and k=log 2 ,to get the population after 20 weeks.
x=

x=

x=
x=403.42
Hence the population after 20 weeks will be 403.42
in which
is the initial population.
