Desculpe-me eu não sei mas irei falar com meu professor!
Answer:
B
Step-by-step explanation:
Let divide g(x) by f(x)

The domain of a rational function cannot equal zero so let set the bottom function to zero.


Square both sides

Also we can simplify the bottom denomiator into a square root function

The domain of a square root function is all real number greater than or equal to zero because a square root of a negative number isn't graphable.
So we must find a answer that
- Disincludes 4 from the interval
- Doesnt range in the negative number or infinity)
- Range out in positve infinity
- The answer to that is B
Answer:
The length of the office is 36.4 ft
Step-by-step explanation:
The length of the classroom = 20 ft long
The length of the office = 20 ft + 82% of the classroom length
Now, 82 % of classroom length = 82 % of 20 ft
⇒ 
or, 82% of 20 ft = 16.4 ft
⇒The length of the office = 20 ft + 16.4 ft = 36.4 ft
Hence, the length of the office = 36.4 ft
6^2 is simply 6x6. which =36
Here, in this situation,
Hypotenuse = 25 feet
base = 13.5 feet
Now, Cos Ф = B / H
Cos Ф = 13.5 / 25
Cos Ф ≈ 1/2
Ф = Cos⁻¹(1/2)
Ф = 45 [ Cos 45 = 1/2 ]
In short, Your Answer would be approximately 45 degrees
Hope this helps!
