The answer will be <span>Negative

Write sin(</span>\frac{5 \pi }{4}) as sin(\pi+\frac{ \pi } {4}<span>)

Using the summation identity will be:
</span>=sin(\pi)+cos(\pi)sin(\frac{ \pi }{4}<span>)
</span><span>
By following the trivial identity, you should get:
=</span>0*\frac{ \sqrt{2}}{2}+(-1) \frac{\sqrt 2} {2}

<span>Remove the parentheses on -1, then multiply</span>
=0*\frac{ \sqrt 2} {2}-1* \frac{ \sqrt 2} {2}

You should get:
- \frac{ \sqrt 2} {2}

Lilit [14]

Answer:

The ordered pair that best describes the location of G' is (-6,2).

Step-by-step explanation:

Reflecting a point over the y-axis:

When a point (x,y) is reflected over the y-axis, it's x coordinate is multiplied by -1, while the y-coordinate stays the same. Thus:

(x,y) -> (-x,y).

Point G is located at (6, 2)

When reflected over the y-axis:

G'(-6,2).

The ordered pair that best describes the location of G' is (-6,2).
