Answer:
x= -40
Step-by-step explanation:
Cost
C(x)=1,600+20x
P(x)=100-x
Revenue=x*p(x)
=x*(100-x)
=100x-x^2
Cost=Revenue
1600+20x=100x-x^2
1600+20x-100x+x^2=0
1600-80x+x^2=0
Solve using quadratic formula
Formula where
a = 1, b = 80, and c = 1600
x=−b±√b2−4ac/2a
x=−80±√80^2−4(1)(1600) / 2(1)
x=−80±√6400−6400 / 2
x=−80±√0 / 2
The discriminant b^2−4ac=0
so, there is one real root.
x= −80/2
x= -40
<h3>
Answer: 75.36 square feet</h3>
Your teacher may want you to type the number only.
==========================================================
Work Shown:
SA = surface area of a cylinder
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*2^2 + 2*3.14*2*4
SA = 75.36
The surface area is roughly 75.36 square feet.

Answer:
Option A
Step-by-step explanation:
Number of components assembled by the new employee per day,
N(t) = 
Number of components assembled by the experienced employee per day,
E(t) = 
Difference in number of components assembled per day by experienced ane new employee
D(t)= E(t) - N(t)
D(t) = 
= 
= 
= 
= 
Therefore, Option A will be the answer.
