Answer:
13
Step-by-step explanation:
because a is the missing number. Well, 21 minus or - 8 is equal to 13.
840=2 times 2 times 2 times 3 times 5 times 7
The bacteria present at t=37 minutes is found to be 8.40, with no change in growth rate.
<h3>What does population growth exponentially mean?</h3>
When a population's per capita growth rate remains constant, regardless of population size, exponential growth occurs, causing the population to grow exponentially as the population increases.
Given:
P = 340
It has been discovered that a specific bacterial population doubles in 20 minutes.
k = 2/20 = 0.1
t = 37 minutes
We know that,
P = P₀
340 = P₀(
)
340 =P₀(40.44)
P₀ = 8.40
As a result, the bacteria that will be present in t=37 minutes is found to be 8.40 with no change in growth rate.

Answer:
k = 1.2
Step-by-step explanation:
Solving for t when the account value is 30,000, we have ...
30,000 = 25,000e^(0.0198t)
30,000/25,000 = 1.2 = e^(0.0198t)
ln(1.2) = 0.0198t
t = ln(1.2)/0.0198
Matching this with the form ...
t = ln(k)/0.0198
we see that k = 1.2.
_____
k is the multiplier of account value in time period t.
