Answer:
Open dot at -1 and shaded to the right.
Step-by-step explanation:
First you have to solve the inequality are you get |y|>-1
Now you can plot the inequality by placing an open dot on -1 since the inequality is greater than.
Since the inequality is greater than, you also have to shade when all y values are greater than -1 so you would shade to the right.

Answer:
<em>The firefighter should extend the ladder at 54° of elevation.</em>
Step-by-step explanation:
<u>Trigonometric Ratios</u>
The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
<em>Tangent Ratio:</em>

The woman is trapped at 91 feet up from the ground, and the firetruck is 67 feet away from the building.
The wall, the ground, and the ladder form a right triangle, where θ is the horizontal angle of the ladder.
Being the height of the woman the opposite leg and the distance where the firetruck is parked, the adjacent leg:

The angle is calculated as the inverse tangent:

The firefighter should extend the ladder at 54° of elevation.
