The true statements is the population was 4800 when the collection of data began. (3rd option)
<h3>What is an
exponential function?</h3>
An exponential equation can be described as an equation with exponents. The exponent is usually a variable.
The general form of exponential equation is f(x) = 
Where:
- x = the variable
- e = constant
When a population grows at an exponential rate, it usually has compound rate of growth. Compound growth refers to the geometric progression of a variable.
The exponential equation used to represent an exponential growth usually have this form:
FV = PV (1 + r)^n
Where:
- FV = future population
- PV = present population
- r = rate of growth
- n = number of years
Given this exponential equation : f(x) = 4800 (1.02)^t
- 4800 = initial population or population when the data collection began
- 2 % = rate of growth
- t = number of years

First, you need to know what is 25 percent of 45, so you do 45 times 25 divided by 100 and you are going to get 11.25. Then you take the 45 and subtract those 11.25, which will give you 33.75 because it's saying how much was it before the sale. That's your final answer.
EXPLANATION
Since the circumference of the circle is 9.42, we can get the diameter by applying the following relationship:

Isolating the diameter:

Plugging in the numbers:

Therefore, the diameter is equal to 3 inches.
Ok so the first thing you would do is input the number where The variables are in the equation so 8^2-5(4)/4
