Answer:
Step-by-step explanation:
The number of parrots in t years after 2010 can be modeled by the following function:
In which P(0) is the number of parrots in 2010 and r is the growth rate, as a decimal.
608 parrots in the forest in 2010.
This means that
Then
When the scientists went back 5 years later, they found 4617 parrots.
This means that
We use this to find 1 + r. So
So
Y = -3(2) +22
Y = -6 +22
Y = 16
You do mass divided by density
26.18 divided by 77 = 0.34. Therefore the percentage change = 66%
