Answer:
634
Step-by-step explanation:
The population of the birds in 2001 = 230000
From 2001 to 2021 = 20 years
Given:
y = 200000
where x is the number of years since 2001.
The population of the birds after 20 can be determined by;
y = 200000
= 200000(3.171211939 x )
= 634.2424
y = 634
Thus, there would be 634 endangered birds in 2021.
