The answer to this problem is: 3x -21
Work: 4x - x = 3x
Final Answer: 3x - 21
Answer:
Step-by-step explanation:
Data provided in the question:
Initial volume of water = 15 liters
Concentration of salt = 4 liters per minute
x be the amount of salt, in grams, in the fish tank after t minutes have elapsed
The unknown concentration of incoming brine c.
Now,
Salt concentration per minute = 
For x amount of salt = 
Therefore,
Models are patterns that are used to predict measurements and populations
<h3>How to model the tree</h3>
The question is incomplete, as the model and the dataset to model that growth of the tree are not given.
So, I will give a general explanation
If the model of the tree follows a linear model (e.g y = 2x + 3), then the model is not reasonable.
This is so because, population and growth cannot be measured by a linear model
However, if the growth of the trees follow an exponential model (e.g y = 2(3)^x), then the model is reasonable
