Answer:
111.4 degrees
Step-by-step explanation:
Let's write cos x = -0.3646. Or, look up the symbols chart at the bottom of your page and click on Ф to obtain this character: cos Ф = -0.3646.
If Ф is in Quadrant III, then the adjacent side is negative and the hypotenuse is positive.
-1
Type this into your calculator: cos -0.3646. Result: 1.934 (radians)
This converts to degrees as follows:
1.934 rad 180 degr
--------------- * --------------- = 111.4 degrees. Note that this angle is in QIII.
1 π rad
The formula that explain the arithmetic sequence is 
Step-by-step explanation:
The formula of the nth term in an arithmetic sequence is
, where
- a is the first term
- d is the common difference between the consecutive terms
∵ 
, 
, 0 , 
are some terms of an arithmetic sequence
∵ The difference between two consecutive terms = -
∴ The difference between two consecutive terms = + 
=
∴ The common difference =
∴ d =
∵ The first term is
∴ a =
- Substitute a and d in the formula above
∴ 
- Simplify the right hand side
∴ 
- Add like terms
∴

Answer:
B
Step-by-step explanation:
Range is y-values, hun which is the second number in each of the ordered pairs. And when you list ranges(y) or domains(x) you do it from least to greatest which is why it goes from negatives to positives in numerical order rather than the order given in the problem.
