Answer: It has two distinct real zeros.
Step-by-step explanation:
The formula that is used to calculate the discriminant of a Quadratic function is the one shown below:
In this case you have the following Quadractic function provided in the exercise:
Let's make it equal to 0:
You can identify that:
Knowing these values, you can substitute them into the formula and then evaluate:
Therefore, since:
You can determine that the it has two distinct real roots.
Answer:
12 + -6i
a=12
b=-6
Step-by-step explanation:
( -4 + 3i ) ( -3 - 2i )
-4 * -3 = 12
3i * -2i= -6i
12 + -6i
Answer:
30°
Step-by-step explanation:
Hi!
Your answer is C.
The vertex is the point where two different rays meet, forming an angle.
It can also simply be the point where 2 straight lines simply meet.
Option A is NOT correct because a vertex is not angle, it is a <em>part </em>of an angle.
Option B is NOT correct because, if there's only one segment, we cannot form a vertex.
See the image below for an example:
