Answer:
D
Step-by-step explanation:
A negative discriminant indicates that the quadratic equation has no real roots.
Thus the graph does not touch or intersect the x- axis
The only graph that does not touch or intersect the x- axis is the fourth one
28 + vector b = -12
vector b = -40
vector b has magnitude 40 units in the negative y direction.
- 4 w - 4 = - 24
- 4w = - 20
w = 5
A rational number is a number that can be written into a fraction. pi, some square roots, e, etc., are irrational numbers(numbers that cannot be written into a fraction).
