Answer:
a)
b)
Step-by-step explanation:
Given the cost function as C(x):
a) Find the average cost function,
if C is the cost of selling x units, The Average can be denoted by:
this is the average cost function
b) The minimum average cost:
To find the minimum average cost, we'll have to differentiate the average cost function . and equate it to zero. (like finding the stationary point of any function)
now just simplify:
we've found the derivative of C(x), now to find the minimum we'll equate this derivative to zero.
and now solve for x
at this value of x the average cost is minimum.
This is the minimum average cost!

To find the volume of a prism, you multiply l x w x h (length x width x height). The length is 8, width is 4, height is 2. 8 x 4 = 32, 32 x 2 = 64.
hope this helped plz tell me if i was right!!!
Answer:
x=5
y=30
x=15
Step-by-step explanation:
y=3x=15, then x=15/3, x=5
x=10, then y=3x=3*10=30
y=3x=45, then x=45/3, x=15
