all real numbers
Step-by-step explanation:
The domain of any exponential function is "all real numbers."
-∞ < x < ∞
Answer:
I think it might be (-12,7)
Step-by-step explanation:
First, you can divide the 2x by 3x to get 2/3.
Then divide 12 and 18. 12/18 = 2/3
Then you would do (2/3) + (2/3) to get 4/3.
The final answer would be 4/3.
Hope this helps :)
Answer:
the record holder is 1260 with 36 factors.
Step-by-step explanation:
You need to know the properties of each function.
Tan is opposite (y) over adjacent (x). Sin>0 means that sin is positive, therefore, it is located on either quadrant 1 or 2. Tan=4/3 so it is located in quadrant 1.
The side of the triangle must be Adjacent=3 opposite=4 and hypotenuse=5
Now, you are asked to find the half angle of Cos which is

By following the formula, cos=3/5 then:

Multiply everything (inside the square

root) by 5


Then just simplify

The answer is Square root of 20 over 5
