As given,
Step 1: Pick any three-digit counting number
Lets pick the number 643
Step 2: Reverse the digits of the original number.
So, reverse becomes 346
Now, it says that the difference of these two numbers has a tens digit of 9.
Lets, check:
So, its true that the difference has a tens digit of 9.
Another example:
Lets take 449
So reverse is = 944
Difference =
Here also the tens digit is 9.
So, the condition applies to all 3 digit numbers.
The proportional graph that corresponds to M = 3n is: Graph C.
<h3>What is a Proportional Graph?</h3>
The constant of proportionality, k, of a proportional graph is given as, y/x. The graph is expressed by the equation, y = kx.
The equation given, M = 3n, represents a proportional relationship where k = 3.
Using a point on graph C, (400, 1,200):
k = 1,200/400
k = 3
Therefore, the graph that corresponds to the situation is: C.

Using a differential equation, it is found that the bacteria's population will triple in 4.75 hours.
<h3>What is the differential equation used in this problem?</h3>
- The bacteria in certain culture increase at a rate proportional to the number present, which means that the population is described by the following differential equation:
- In which k is the growth rate.
Applying <em>separation of variables</em>, the solution is:
The number of bacteria doubles in three hours, hence P(3) = 2P(0), which is used to find k.
Hence:
It triples when P(t) = 3P(0), hence:
The bacteria's population will triple in 4.75 hours.
