d. 3.76
Step-by-step explanation:
Given that:
Revenue function:
Cost Function:
We know that,
Answer a: Profit = Revenue - Cost
Answer b:
P(100) = ?
Putting value of x as 100 in above equation:
Answer c:
P'(x) = ?
Differentiating the equation
Answer d:
P'(100) = ?
Putting x = 100 in equation
Answer:
y-2=2(x-1)
Step-by-step explanation:
Pick any two points from the line (example: (1,2) and (2,4))
Find the slope of them
Reminder: Slope is changes in y/changes in x or y2-y1/x2-x1
In this case, m= 4-2/2-1 which is 2
Now to use slope point form, chose any point and substitute it into this equation:
y-y1=m(x-x1)
Substituting it would get
y-2=2(x-1)
Or
y-4=2(x-2)
Answer:
x = 7
Step-by-step explanation:
I reversed it for easy viewing:
(x+7)/3x = 2/3
<=> (x + 7).3 = 2.(3x)
<=> 3x + 21 = 6x
<=> 21 = 6x - 3x
<=> 3x = 21
<=> x = 7
Your geometric series starts with 6, and then you get the next term by multiplying the previous one by 1/3. So, the first five terms are
And if we sum them we have
