Answer:
Step-by-step explanation:
Given that a company fixed costs are 400 dollars
and variable cost = 
per unit and x the no of units produced
Selling price = 
per unit
a) Break even units
At break even units selling price = variable cost
Break even units = 76
b) Revenue = Sales - total costs
= 
Use derivative test to get max revenue
R'(x) = 
R"(X) <0
So maximum when I derivative =0 or when
x=38
c) price when x =38 is
Answer:
A or C ( they are the same answer in your Q)

Answer:
original number is 18.07
Step-by-step explanation:
Let the original number be x
x - 17% of x = 15
x* (1 - 0.17) = 15
x * 0.83 = 15
x = 15/0.83
x = 18.072289156
Or if your wording meant 17% of a number is 15 then:
x * 17% = 15
x *0.17 = 15
x = 15/0.17 = 88.23529...
but I think you meant "decreased by 17%" so I choose x = 18.07
Answer:
4.647 to the nearest thousandth.
Step-by-step explanation:
The formula for the length of an arc between x = a and x = b is
a
∫ √( 1 + (f'(x))^2) dx
b
Here f(x) = √x so
we have ∫ (√( 1 + (1/2 x^-1/2))^2 ) between x = 0 and x = 4.
= ∫ ( √( 1 + 1/(4x)) dx between x = 0 and x = 4.
This is not easy to integrate but some software I have gives me the following
length = √17 + 1/8 log(33 + 1/8 √17)
= 4.647.
First find the constant k. For inverse variation, k=yx.
k=(8/3)*3=8
8=yx or y=8/x
8=4y
y=2
Hope this helps.
