simple interest formulae = PRT/100
where
p stands for percentage (2%)
r stands for rate ( 900)
t stands for time (2 years )
2×900×2/100
=3600/100
=36
There is a pattern. Each number is added by 5. So take 22 and add 5 to get 27. Just repeat until you find your answer, which would be 42.
9a. The answer is 1.07% because the function shows an exponential growth in the exponential function.
9b. The first population was about 2622 because it shows that the first year is the domain to find the range of the function when x is equal to 1.
