Answer:
1075 sq ft
Step-by-step explanation:
There are a few ways to do this but I am only going to show one.
35 x (25 + 8) - (5 x 8 + 8 x 5) = 1155 - 80 = 1075
Using the profit concept, it is found that the break-even point is of 61.6 units.
- Profit is given by revenue subtracted by cost.
- The break-even point is when the revenue is the same as the cost, which means that the profit is zero.
In this problem:
- Variable cost per unit x of $217, fixed cost of $5,420, thus, the cost equation is given by:
Selling price per unit of $305, thus, the revenue equation is given by:
The break-even point is the <u>value of x</u> for which:
Then
The break-even point is of 61.6 units.

Answer:
5/2
Step-by-step explanation:
<u>Rise</u> = <u>5</u>
Run 2
Now, with that, our y intercept is -6 because the line hits the y axis at -6 units. Then, we can setup our own equation for y=
and that is y=5/2 x -6
Then I have attached a graph below to certify my answer.
Answer: plan A lasts for 0.5 hour. Plan B lasts for 0.75 hour.
Step-by-step explanation:
Let x represent the duration of plan A.
Let y represent the duration of plan B.
On Friday there were 3 clients who did plan A and 2 who did Plan B.
Joe trained his Friday clients for a total of 3. It means that
3x + 2y = 3- - - - - - - - - -1
On Saturday there were 5 clients who did plan A and 6 who did plan B. Joe trained his Saturday clients for a total of 7 hours. It means that
5x + 6y = 7- - - - - - - - - 2
Multiplying equation 1 by 5 and equation 2 by 3, it becomes
15x + 10y = 15
15x + 18y = 21
Subtracting, it becomes
- 8y = - 6
y = - 6/-8
y = 0.75
Substituting y = 0.75 into equation 1, it becomes
3x + 2 × 0.75 = 3
3x + 1.5 = 3
3x = 3 - 1.5 = 1.5
x = 1.5/3
x = 0.5
I want to believe the equation is,
f(x) = -5/x
This can be written as;
f(x) = y
y = -5 x⁻¹
derivative = dy/dx = (-1)(-5)x(⁻1-1)
= 5x⁻²
Derivative at x=11,
dy/dx = 5(11)⁻²
= 5/(11²)
= 5/121
So, the derivative of f(x) = -5/x at x=11 is 5/121.
