ANSWER

EXPLANATION
We want to find the number of years that it will take the population to double.
To do this, we have to apply the exponential growth function:

where y = final value
a = initial value
r = rate of growth
t = time (in years)
For the population to double, it means that the final value must be 2 times the initial value:

Substitute the given values into the function above:

To solve further, convert the function from an exponential function to a logarithmic function as follows:

Solve for t:

It will take 9 years for the population to double.
You divide 5 by 8 it’s really easy
Answer: sqrt(55)
Hypotenuse of triangle on the right is 3sqrt(5) so if you plug that in for b on the triangle on the left you get sqrt(55) for your answer
The answer is D, you have to distribute the negative sign to each number in the second parenthesis
Answer:
3
