An example of quadratic equation with this behavior is:
Which is sketched at the end of this answer.
A quadratic equation has the format:
It's roots are given by:
The number of roots depends on the discriminant 
, that is:
- If
, it has two different real roots. - If
, it has one real root. - If
, it has no real roots.
In this problem, it will have only positive y-values if: and 
Thus, an example is:
Which is sketched below.

Answer:
10 to the power of 2
Step-by-step explanation:
Answer: Yes 
is one possible angle name
Another name is 
When it comes to naming an angle this way, all we need to worry about is the vertex point. This is where the angle hinges (think of a door or a pair of scissors). In this case, the hinge or vertex point is at point D. The vertex is always the middle letter of any three-letter sequence. The order of the other two points does not matter.
This is why saying "angle FDE" is the same as "angle EDF".
Answer:
The surface = pi*10cm2
Step-by-step explanation:
The area of any rectangle is Base * Height,
We know that the square originally has 10cm High, when is rolled to form a cylinder, it's new shape has a bottom side that is equals to a circle.
The length of a circle is 2*pi*Radio= pi*Diameter.
Since the square has the same length in each side, we know that pi*Diameter= 10cm*pi
The surface (area) of the cylinder is= Base * Height= 10cm*10cm*pi
