The answer is (-∞.∞).
Draw out a number line. Plot 0 and -4 on the number line.
Shade to the left of x = 0, and have a filled in circle at the endpoint. This is the graph of x≤0
Then graph x ≥−4 by plotting a filled in circle at -4, and shading to the right.
Note how the two graphs overlap to cover the entire real number line
So if we have x≤0 or x≥−4 then we're basically saying x is any real number. To write this in interval notation, we write (−∞,∞)
This is the interval from negative infinity to positive infinity (or just infinity). We exclude each endpoint because we can't actually reach infinity itself. Infinity is not a number. Infinity is a concept
Side note: if you change the "or" to "and", then the solution to x≤0 and x≥−4 would be [-4, 0][−4,0] to indicate the interval from x = -4 to x = 0, including both endpoints. This is the region where the two graphs overlap.

Answer:
0.25 Converges
Step-by-step explanation:
First, we need to expand our series so that we get the following:
We can then use the series ratio test on each term. (L < 1 = absolutely convergent)
=
⇒ converges
⇒ converges
converges + converges
= converges

Answer:
21,600
Step-by-step explanation:
If in the coding system being used there are 6 vowels (A, E, I , O, U and Y)
Number of Consonants =26-6 =20
- First entry must be a consonant, therefore the first entry can be chosen in 20 ways.
- The second entry must be an integer 1 through 9, therefore the second entry can be chosen in 9 ways.
- The third entry must be one of the six vowels, therefore the third entry can be chosen in 6 ways.
- The last entry must be a consonant, therefore the last entry can be chosen in 20 ways.
Therefore:
Number of different possible ciphers =20*9*6*20
=21600
Answer:
x = 135 degrees hopes this helps
Step-by-step explanation:
the whole triangle is equal to 180
180-41=139-94=45
so the missing angle in the triangle is 45
and that means the angle on the outside and the angle we just found 45 equals to 180
180-45=135
so 135 is the outside's missing angle
