Answer:
The graph of f has an inflection point at x = 0.
Step-by-step explanation:
An inflection point occurs when the second derivative changes signs. Since f"(x) is decreasing and has an x-intercept at 0, it changes signs from + to -, so there is an inflection point at x = 0.
Rearrange to get x on its own on one side of the equation:
x = 57 - 11
x = 46
Answer:
0.6x = 87
Step-by-step explanation:
Hi, to answer this question we have to write en equation:
We have to multiply the variable x by the percentage given (60%) in decimal form (divided by 100). That expression must be equal to 87.
Mathematically speaking:
x (60/100) = 87
0.6x = 87

Answer:
a)
b)
Step-by-step explanation:
Given that
C = 100 + 25 x - 120 ln x ,x ≥ 1.
The average cost function given as
Therefore
To find average minimum cost
100 + 120 (1-lnx) = 0
ln x =1.833
x=6.25
