Scientists were studying a rare species of parrot they went to fourth in the year 2010 and found there were 608 pairs in the for

Stells [14]

Answer:

6926 pairs in 2016.

Step-by-step explanation:

The number of pairs in t years after 2010 is modeled by the following function:

$P(t) = P(0)(1+r)^{t}$

In which P(0) is the number of pairs in 2010 and r is the growth rate, as a decimal.

608 pairs in 2010

This means that $P(0) = 608$

$P(t) = P(0)(1+r)^{t}$

$P(t) = 608(1+r)^{t}$

4617 pairs five year later.

So P(5) = 4617. We use this to find 1 + r.

$P(t) = 608(1+r)^{t}$

$4617 = 608(1+r)^{5}$

$(1+r)^{5} = \frac{4617}{608}$

$1 +r = \sqrt[5]{\frac{4617}{608}}$

$1 + r = 1.5$

$P(t) = 608(1.5)^{t}$

How many pairs in 2016?

2016 is 2016 - 2010 = 6 years after 2010. So this is P(6).

$P(t) = 608(1.5)^{t}$

$P(6) = 608(1.5)^{6} = 6926$

6926 pairs in 2016.
