Answer:
Step-by-step explanation:
Given
Solving (a): The cost function:
From the given parameter, it shows that the number of floor has no effect on the floors.
So, represent the floors with x.
The cost function is:
Solving (b): The slope and its interpretation
A function is represented as:
Where:
By comparing: to
So:
<em>What it means is that, no matter the number of floors, the cost remains unchanged.</em>

Step-by-step explanation:
In order to solve this "question," you must provide a graph.
Answer:
The value of x is 5 units ⇒ C
Step-by-step explanation:
In the given figure
∵ Δ ABC is a right triangle at vertex B
∵ AC is its hypotenuse
∵ BD ⊥ AC
∴ (BD)² = AD × DC
∵ BD = 10 units
∵ AD = x units
∵ DC = 4x units
→ Substitute them in the rule above
∴ (10)² = x × 4x
∴ 100 = 4x²
→ Divide both sides by 4
∵ 
= 
∴ 25 = x²
→ Take √ for both sides
∴ 5 = x
∴ The value of x is 5 units
