Suppose the growth of a population in millions is modeled by 3.2*(4.72)^t. What is the size of the population in millions?
To find the size of the population, you need to substitute the value of "t" into the given equation: 3.2*(4.72)^t.
In this equation, "t" represents the time passed, and the term (4.72)^t represents the growth factor. The growth factor is the value by which the population increases or decreases over time.
Let's say you have a specific value for "t," such as t = 2. To find the population size at that time, substitute the value of t into the equation:
Population Size = 3.2*(4.72)^2
Now let's calculate the population size using this equation.
First, calculate the exponent: 4.72^2 = 22.2784
Next, multiply the growth factor by the initial population size: 3.2 * 22.2784 = 71.28928
Therefore, the size of the population is approximately 71.28928 million.
