Answer:
2,000 bacterias
, because after 3 hours theyre 100 bacteria so after 6 hours there will be 800 bacterias so if its 9 hours you will have 2,00 bacterias.
How many bacteria will there be in 10 hours?
The number of bacteria in a culture is increasing according to the law of exponential growth. The initial population is
250 bacteria
, and the population after 10 hours is double the population after 1 hour.
How many bacteria will there be in 8 hours?
After 8 hours we have
32 g of bacteria
and after 10 hours we have 45.25 g of bacteria.
How many bacteria are there after t hours?
(b) How many bacteria are there after t hours? Thus the function
P(t) = 500e1
.
How much bacteria grows 5 hours?
Under ideal conditions, this doubling may occur as frequently as every 15 minutes, so that within 5 hours there will be
more than a million cells from the original
single cell. If there are 1000 original cells instead of a single one, there will be over 1 billion cells in 5 hours.
How many bacteria will there be after 6 hours?
How many bacteria will there be after 7 hours? The number of bacteria in a culture is increasing according to the law of exponential growth. After 3 hours, there are 100 bacteria, and after 6 hours, there are
800 bacteria
.
How many bacteria will there be in 4 hours?
Since a single bacterium will divide 16 times in four hours cells, then in four hours, a single bacterium will have divided into 2^16 =
65536 new cells
.
How long will it take the number of bacteria to reach 20 000?
Recall that the original question is to find the doubling period, so we are not done yet. We need to find the time, t, when the population n(t) = 20,000. We use the population growth function found above and solve the resulting exponential equation
How many bacteria will there be in two days?
There will be about
65,536,000 bacteria
after 2 days.
In what temperature range will most bacteria survive but will not multiply quickly?
Between 0°C and 4°C
(or 32°F and 40°F), most bacteria will survive but will not multiply quickly.
How many bacteria does the model predict will be present after 5 hours?
There are
80,686 bacteria
in the population after 5 hours.
How many times does bacteria multiply in 24 hours?
If we apply the formula 2
n
, where n is equal to 48, the single cell would give rise to 2
48
or
281,474,976,710,656 cells
at 48 generations (24 hours).
How quickly can bacteria grow in 24 hours?
Generation times for bacteria vary from
about 12 minutes to 24 hours
or more. The generation time for E. coli in the laboratory is 15-20 minutes, but in the intestinal tract, the coliform’s generation time is estimated to be 12-24 hours.
Is Doubling exponential growth?
When the growth of a quantity is exponential,
the amount doubles in a certain interval of time
. We speak of doubling time. An exponential curve.
