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
First we'll multiply the second equation by -2
Now let's add the new equation and the first one.
We found y's value. We'll plug it in one of the equations to find x's value.
Solution ;
