<u>Given</u>:
A population numbers 15,000 organisms initially and grows by 19.7 % each year.
Let P represents the population.
Let t be the number of years of growth.
An exponential model for the population can be written in the form of
We need to determine the exponential model for the population.
<u>Exponential model:</u>
An exponential model for the population is given by
where a is the initial value and
and b is the rate of change.
From the given, the value of a is given by
Also, the value of b is given by
Thus, substituting the values of a and b in the exponential model, we get;
Thus, the exponential model for the given population is
Answer:
The value of the other two numbers is 31.01
Step-by-step explanation:
Let the two numbers equal to each other be x
One of the numbers is 22.8
The sum of three numbers is -39.22.
So, x+x+22.8=-39.22
2x+22.8=-39.22
2x=-39.22-22.8
2x=-62.02
x=-31.01
Hence the value of the other two numbers is 31.01
