For this case we have a quadratic equation of the form:
What we must keep in mind to know which direction opens the parabola, is the value of a.
We have two options:
If a <0 the parabola opens down
If a> 0 the parabola opens up
We have the following equation:
We observed that:
Therefore, the parable opens up.
Answer:
the direction that this parabola opens is:
Upwards

Given:
Height of cylinder, h = 9 cm
Radius, r = 3 cm
Total amount of paper the company has = 8138.88 cm²
Let's find the number of labels that can be made given that the label covers only the side.
Here, we are to apply the formula for the surface area of a cylinder.
We have:
The 2πr² represents the area of the top and bottom circle of the cylinder.
Since the label covers only the side, we are to exclude the 2πr².
Hence. we have:
WHere:
r = 3 cm
h = 9 cm
Thus, we have:
Now, the number of labels they can make is:
Therefore, the company can make 48 labels.
ANSWER:
48 Labels
