C is the midpoint of AD. B is the midpoint of AC. BC = 14. What is<br> the length of BD?
serg [7]

Answer:

Length of segment BD = 42 units

Step-by-step explanation:

Since C is the midpoint of AB,

Then segment AC = segment CD

Since B is the midpoint of BC,

Then the length of segment AB = Length of segment BC = 14 units

Length of AC = 2 × (14)

                      = 28 units

Length of AC = length of CD = 28 units

Length of segment BD = Length of BC + length of CD

                                      = 14 + 28

                                      = 42 units

Therefore, length of segment BD is 42 units.

Why is it important to consider multiplicity when determining the roots of a polynomial equation? Write your response, citing ma
Svetradugi [14.3K]

Answer:

Step-by-step explanation:

The multiplicity of a root of a polynomial equation is the number of times it appears in the solution.

Multiplicity is important because it can tell us two things about the polynomial that we work on and how it is graphed. first: it tells us the number repeating factor a polynomial has to determine the number of the real (positive or negative) roots and complex roots of the polynomial.

About graph behaves at the roots : Behavior of a polynomial function near a multiple root

The root −4 is a 'simple' root (of multiplicity 1), and therefore the graph crosses the x-axis at this root. The root 1 is of even multiplicity and therefore the graph bounces off the x-axis at this root.
