Answer:
10.75%
Step-by-step explanation:
Given that :
Population of orcas in 2018 = 465
Population in 2020 = 515
The per capita growth rate acn be calculated using the relation:
C
[(Population change / initial population) * 100]
Population change = population (2020 - 2018) = (515 - 465) = 50
[(50 / 465) * 100]
(0.1075268 * 100) %
10.7526%
= 10.75%
I used the completing the square method to get the (x+2)^2. The final line is in standard form.
