Answer:
Absolute increase in population will be 2100
And percentage increase will be 60 %
Step-by-step explanation:
We have given population in 2005 is 3500
And population in 2009 is 5600
So absolute increase in population = 5600-3500 = 2100
We have to find the percentage increase in population
So relative percentage increase in population will be %
So population will increase by 60 %
Answer:
minimum value of function is .
Step-by-step explanation:
Given function represents a parabola.
Now, here coefficient of is positive , so the parabola will be facing upwards and thus the function will be having a minimum.
Now, as we know that minimum value of a parabolic function occurs at
x = .
Where , b represents the coefficient of x and a represents the coefficient of .
here, a = 2 , b = -6
Thus =
=
So, at x = minimum value will occur and which equals
y = 2× -
+ 9 =
.
Thus , minimum value of function is .
