Alright, so the rate of change is the same thing as the slope, so we can find this by using the slope formula (which I took a picture of because it's super messy to type it out like this)
Now that we know the slope formula, we need to find the x values and the y values to plug into the equation. We'll say that the years are our x values and the money spent (in billions) are our y values. Now that we've set up an axis, we can create points! Our points would be (2000, 1243) and (2005, 1838)
Now we can plug our points into our equations! On the top of our equation, we'll put (1838-1243), and on the bottom we'll put (2005-2000). When we simplify that, we end up with 595/5, which simplifies to 119. Now we know that the rate of change for the credit cards was 119 billion!

Answer:
The statements that are true are:
- 1.575 was the coffee yield , in thousands of kilograms,before the honeybees were introduced.
- 1.16 represents the growth factor that reveals the rate at which the coffee yield increases.
- 2 is the number of times the coffee yield was compounded per year.
Step-by-step explanation:
We are given a function that models The coffee yield, in thousands of kilograms, t years after the introduction of the honeybees.
Also, the coffee yield increases according to a model where the exponential change is compounded semiannually .
The function is given by:
Here when t=0, i.e. before the honeybees were introduced we have:
Also, the rate of increase i.e. the growth rate is denoted by : 1.16
Also, 2 represents the number of times the coffee yield is compounded per year.
