Answer:
18107.32
Step-by-step explanation:
Set up the exponential function in the form:

so P is the new population,
is the original population, R is the rate of increase in population, and t is the time in years.
You have to use the information given to find the rate that the population is increasing and then use that rate to find the new population after more time passes.
![13000 = 6000(R)^7\\\\\\frac{13000}{6000} = R^7\\\\\sqrt[7]{\frac{13000}{6000} } = R\\\\\\ R = 1.116786872](https://tex.z-dn.net/?f=13000%20%3D%206000%28R%29%5E7%5C%5C%5C%5C%5C%5Cfrac%7B13000%7D%7B6000%7D%20%3D%20R%5E7%5C%5C%5C%5C%5Csqrt%5B7%5D%7B%5Cfrac%7B13000%7D%7B6000%7D%20%7D%20%3D%20R%5C%5C%5C%5C%5C%5C%20R%20%3D%201.116786872)
Now that you found the rate, you can use the function to find the population after another 3 years.

So the population is 18107, rounded to the nearest whole number.
Answer: Yes, radicals can be rationals.
Step-by-step explanation:
Yes, a radical can be rational.
If a square root is a perfect square, you will obtain an integer, and by definition, the integer are rationals (they can be written as simple fractions).
Example:

If the radical has a root <em>n </em>and number inside of the root can be written as a power with exponent
, then you will obtain a radical.
Example:
![\sqrt[3]{64}=\sqrt[3]{4^{3}}=4=\frac{4}{1}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D%3D%5Csqrt%5B3%5D%7B4%5E%7B3%7D%7D%3D4%3D%5Cfrac%7B4%7D%7B1%7D)
