Answer:
A
Step-by-step explanation:
<em>Okay so, im not the best at explaining, but so we have a percentage. its 25%. you want to take the 25% and put it over 100 because a percentage is a number or ratio expressed as a fraction of 100. so it will be written as 25%/100</em>
<em />
<em>divide 25 by 100 and you get 0.25, correct? so that's one step further towards the answer.</em>
<em>then we write x/90 because we don't know (well we do) what we're gonna put. but, we're gonna multiply 0.25 by 90 and we get 22.5, which is equivalent to </em><em>22.50</em><em>.</em>
Given:
Giant panda population in 2014 = 1864
The giant panda population in China is increasing at a rate of 1.5% each year.
To find:
The function that models the panda population since 2014.
Solution:
Since population of giant panda is increasing, therefore the function is the exponential growth model.
The general exponential growth model is:

Where,
is the initial population, r is the growth rate in decimal and t is the time period.
Putting
, we get


Where, t is the number of years since 2014.
Therefore, the required exponential growth model is
.
