Use the drop-down menus to identify the underlined phrase in each sentence. The students carrying boxes into their new dorm room

zaharov [31]

The phrases from each of the sentences are most likely:

<u>Participial phrase </u>
<u>Infinitive phrase </u>
<u>Gerund phrase</u>

A participial phrase is the collection of words in a sentence which is made up of a participle, and a modifier. They perform various functions in a sentence such as being either the objects, or adding extra meaning to the word.

An infinitive phrase is a group of words which has an infinitive and also gives extra information about another word.

A Gerund phrase is a collection of words which has a gerund and another word which modifies a word. Some examples include: "Biking is such a fun sport".

An infinitive is a word that usually begins with a verb "to + extra word" for example, to eat, to walk, etc.

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's asserti

nadya68 [22]

No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect

<h3>Perpendicular lines</h3>

In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

$m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1$

For the slope of ln:

$m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\$

For the slope of mn:

$m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\$

If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

$m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2$

Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect
