Answer:
The point of diminishing returns (x , y ) is (11, 21462)
Step-by-step explanation:
From the question we are told that
The function is
Here R(x) represents revenue (in thousands of dollars) and x represents the amount spent on advertising (in thousands of dollars).
Now differentiating R(x) we have
Finding the second derivative of R(x)
at inflection point
So
=>
substituting value of x into R(x)
Now the point of diminishing returns (x , y ) i.e (x , R(x) ) is
(11, 21462)
Answer:
The answer to your question is: midsegment = 35 units
Step-by-step explanation:
Use the Thales' theorem
43( 3x + 55) = 86( 6x + 5)
129x + 2365 = 516x + 430
129x - 516x = 430 - 2365
-387x = -1935
x = -1935 / -387
x = 5
Midpoint length = 6(5) + 5
= 30 + 5
= 35 units
