Answer:

Step-by-step explanation:
We can write this rate as an ordinary differential equation.

Where a is proportional constant, P the population variable, and t the time.

Integrating each side of the equation.



To find C we need to use the initial condiction, it means evaluae P at t=0.


Now, we use the sentence the population has doubled in 5 years.

We can find "a" in this condition.




Finally, let's find how long will it take to triple.

If triangle MNO is congruent to triangle PQR then side OM is congruent to side RP and equals 9
125.638 rounded to the nearest hundredth equal 125.64
<h3><u>The unknown number is equal to 4.</u></h3>
8x - 27 = 5
Add 27 to both sides.
8x = 32
Divide both sides by 8
x = 4
