Answer:

1

Step-by-step explanation:

SinA+sin²A= 1

sinA=1-sin²A

sinA=cos²A

cos²A= sinA

Now,

Cos²A+cos⁴A=cos²A+(cos²A)²

Replace cos²Awith sinA

= sinA+sin²A

=1

cos²A + cos⁴A=1

Hope it helps :)

A line segment has endpoints at (–1, 4) and (4, 1). Which reflection will produce an image with endpoints at (–4, 1) and (–1, –4
katrin2010 [14]

Answer:- A reflection of the line segment across the line y = –x .


Explanation:-

A reflection over the line y = -x, the x-coordinate and y-coordinate interchange their places and they are negated (the signs are changed).

Given :- A line segment has endpoints at (–1, 4) and (4, 1) such that it reflects produce an image with endpoints at (–4, 1) and (–1, –4).

(-1, 4)→(-4, 1) and

(4, 1)→(-1, -4)

Thus this shows a reflection of the line segment across the line y = –x.

guajiro [1.7K]

Answer:

A). Participle phrase.

Step-by-step explanation:

'Participle phrases' are defined as the phrases that consist of a participle(present or past) followed by modifiers and their object plus any/or complements. These phrases primarily function as adjectives by providing information about a noun or pronoun in the sentence.

In the given sentence, the underlined portion('stepping from the embrace') is a participle phrase as it begins with a participle('present as it ends with 'ing') followed by the modifier prepositional phrase 'from the embrace'(as an adverb). It is <u>functioning as an adjective as it modifies the pronoun 'she' in the sentence</u>. Thus, <u>option A</u> is the correct answer.

R  = 1     : a = 5×247 + 1  = 1236

R  = 2     : a = 5×247 + 2   = 1237

R  = 3     : a = 5×247 + 3  = 1238

R  = 4     : a = 5×247 + 4  =  1239
