Answer:
The answer is "Option A and Option B"
Step-by-step explanation:
In question 1:
The fixed cost=2621.21
The unit variable cost=35.58
Calculating the total cost for 45 boat slips:

In question 2:
It is the pure fixed costs that remain consistent in total regardless of dynamic loads. An overall cost B both for 1000 and 2000 unit is unchanged, therefore the Cost B is a fixed sum.
For this case we have the following quadratic equation:

Where:

By definition, the discriminant of a quadratic equation is given by:

We have to:
Two different real roots
Two different complex roots
Two equal real roots
Substituting the values we have:

So, we have two different complex roots
Answer:
Two different complex roots
<h2>
1. y-intercept</h2>

The quadratic function
represents a parabola. In fact, the graph of a quadratic function is a special type of U-shaped curve called a parabola. To find the y intercept, we set
as follows:

<h2>
2. x-intercepts</h2>

To find the other x-intercept, we must set
as follows:

Therefore, the other x-intercept is
. You can see both the y-intercept and the x-intercepts in the figure below.
