Hello,
45° since a tangentiel angle is the half of the angle in the center corresponding.
Answer:
= 62.8
Step-by-step explanation:
35 - 13 = 22
Now,
23 are boys
here
22/35 * 100
= 62.8
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.
