You will need to use formula x= -b/2a because the min value will by the vertex of function.
x= -(-92/(2*.2)) = 230
then plug in x value
C=0.2(230)^2-92(230)+11,165= 585
Answer:
option 4 is the answer to this question
This is very easy to solve once you understanding writing equations. In this case, we could do n+6=100 because we know that the number of songs he has now (n) plus 6 will equal 100. Below is a solution for this equation.
n+6=100
-6 -6
n=94
After solving our equation, we know that Kirk has 94 songs.
The answer is (2/9)^3 = 0.01097
