Answer:
At ; I = 3, P is at maximum
Step-by-step explanation:
P ( I ) = ![[ \frac{80 I}{I^2 + I + g } ]](https://tex.z-dn.net/?f=%5B%20%5Cfrac%7B80%20I%7D%7BI%5E2%20%2B%20I%20%2B%20g%20%7D%20%5D)
at I = 3
P" ( I ) < 0
therefore at I = 3 the value of P( I ) is at maximum
attached below is the detailed solution
It is complementary and value of x is 20
Answer:
area = 132 cm²
Step-by-step explanation:
area of rectangle = 7 x 12 = 84
area of one triangle = 8 x 6 x 0.5 = 24
total area = 84 + 24 + 24 = 132 cm²

Answer:
5 and 24
Step-by-step explanation:
1) replace the x's with 125 | c(x)=120+4(125)/(125)
620/125=5 simplify numerator
x=5
2) replace c(x) with 9 | 9=120+4x/x
9x=4x+120 multiply both sides by x
9x-4x=4x+120-4x subtract both sides by -4x
5x=120 divide both sides by 5
x=24
so, it costs about 5 dollars per book when 125 are printed
and, if it costs 9 dollars per book, 24 should be printed
