Explanation:
A line segment is <u>part of a line</u> that connects points. It limited consequently, it has length.
- Duru's definition: A line segment is a line connecting two endpoints
It is missing that it is just a part of the line. A ray also connects two points but extends infinetly in one direction. Thus, Duru's definition is not so specific.
That justifies teacher's comment:
- Teacher's comment: What you've written is true, but it isn't a correct definition. A ray would also fit your defenition
Second definition:
- Oliver's definition: A line segment is when three points are all on the same line.
The constraint of a line segment to three points all on the same line corresponds to collinear points. Two points always form a line,, but three points lie on a line only in they are collinear.
That justifies, theacher's comment:
- Teacher's comment: Were you thinking of the team collinear?
Third definition:
- Carlos' definition: A line segment is part of a line, not the whole thing.
Mathematicall language is formal. You must use precise words. An expression as 'whole thing" is not formal.
That justifies teacher's comment:
- Teacher's comment: I think you have the right idea, but you need to be more careful with your language.

where is the question i cant answer it if i cant understand it where to ans
Answer:
<em>B.) M + 7</em>
Explanation:
Since the average (arithmetic mean) of two numbers is equal to the sum of the two numbers divided by 2, the equations X = m+9/
2
, Y = 2m+15/2
, Z = 3m+18
/2 are true. The average of x, y, and z is given by x+y+z
/3
. Substituting the expressions in m for each variable (x, y, z) gives:
[

This fraction can be simplified to <em>m+7.</em>
Based on the standard formula and data in the question, the frequency of a sound source that produces the same wavelength in 20∘c air is "<u>115.87Hz</u>."
<h3>What is the frequency of a sound source?</h3>
The <u>frequency of a sound source</u> is the quantity of waves that move through a point per unit of time.
Typically, a sound wave arises from a source vibrating at a frequency f, propagates at v, and has a wavelength λ.
Therefore, in this case, we have
Velocity (v) of sound in air = 343 m/s
Wavelength (λ) = 2.96 m
Frequency (f) =?
f = v ÷ λ
f = 3.43m/s ÷ 2.96m
=> 115.87Hz
Hence, in this case, it is concluded that the correct answer is 115.87Hz.
