Answer:
a) 
b) 
c) 
Step-by-step explanation:
For total cost function
, average cost is given by
i.e., total cost divided by number of units produced.
Marginal average cost function refers to derivative of the average cost function i.e., 
Given:
Average cost = 
a)
At x = 50 units,

b)
Average cost = 
c)
Marginal average cost:
Differentiate average cost with respect to 
Take 
using quotient rule, 
Therefore,

Answer:
<h2>Check the explanation.</h2>
Step-by-step explanation:
The function is given by
.
In order to get the y intercept, we need to put x = 0.
x = 0 gives, y = 0.
Hence, the y-intercepts of the function is 0.
As the value of x approaches to infinity, the value of y tends to -2.
Hence, the domain of the function is
, where G is a finite number.
The range of the function is
.
26 is the answer. hope this helps a bunch
Answer:
Value of d is:
48
Step-by-step explanation:
We are given a matrix M as:
M=![\left[\begin{array}{ccc}a&b\\c&d\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%5C%5Cc%26d%5Cend%7Barray%7D%5Cright%5D)
We are given that:
a=19, b=24 and c=38
We have to find the value of d so that M is singular
i.e. determinant of M=0
i.e. ad-bc=0
i.e. 19d-24×38=0
i.e. 19d=24×38
i.e. d=
i.e. d=48
Hence, Value of d is:
48
