Answer:
Domain of given function f(x) is all real number.
A is correct.
Step-by-step explanation:
We are given an exponential function.
Domain is a input value of x where function is defined. It is exponential function defined everywhere. Therefore, Domain of exponential function is all real number.
Domain in interval form:
Thus, Domain of given function f(x) is all real number.
Mean is just the average of all of them
So... 5 + 4 + 18 + 19 + 12 + 20 + 12 + 12 = 102
Then you divide that number by the amount of numbers you have so 102 / 8 = 12.75 or rounding it up to 13
For median you have to first put them in order from smallest to largest.
So 4 5 12 12 12 18 19 20
Then you have to find the middle number between them but in this case we have two... 12 and 12. Since they're the same number, the median is 12.
Answer:
Step-by-step explanation:
To solve this problem one can use the trigonometric ratios, these ratios are the following,
In this problem, one is given the adjacent side, and is asked to find the opposite side, thus use the function (). Substitute in the given value and solve,
Inverse operations,
Solve,

log6 [x. (2x-7)]=log6 (6^2)
x. (2x-7)=36
2x^2-14x-36=0
2x +4
x -9
(2x+4)(x-9)=0
x= -2
x=9
The relationship between diameter and radius can be expressed like this:
Diameter = 2 x Radius.
