Answer:
n ≥ -3
Step-by-step explanation:
If n can be <em>no less than</em> -3... then we know that n has to be bigger than or equal to -3.
This could also be said as <em>greater than or equal to</em> -3
Conveniently enough... there is a sign for <em>greater than or equal to</em> and it is ≥

<u>Trigonometric Ratios
</u>
The ratios between the sides of a right triangle are called trigonometric ratios.
If any of the acute angles is chosen as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides and the hypotenuse.
The image shows a right triangle with a tree and the ground forming a right angle and an elevation angle of 33°.
This angle of 33° has a side of 30.5 m as its adjacent leg and the height of the tree X as the opposite side.
The trigonometric ratio that relates both legs is the tangent:

Solving for X

Using a calculator:
X = 19.81 m
The height of the tree is 19.81 m
Answer:
7/12
Step-by-step explanation:
3*4=12. 4/12+3/12=7/12.
The domain of this expression is all real numbers except where the expression is unidentified. In this case, there is no real number that makes this expression unidentified.
