Answer:
C.)
Step-by-step explanation:
There are multiple technical ways to explain this but the best one that works for me is the "vertical line test" can be used to find a function or non function. All you have to do is position your pencil vertically, place it to the far left of the graph drag it horizontally across to the right side of the graph. If your pencil is making contact with two lines at one time, it is NOT a function. Hopefully this makes sense.
Only you can do that yourself, no one online can do that for you.
What is the total number of students? you need to divide 260/total number
WELL 22.5/32 is 70% so to just get that you need to get roughly 9.5 questons wrong
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.
