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.
