We have to find the domain of the function:
f ( x ) = ln ln ln x
x > 0
ln x > 0
x > 1
and finally: ln ( ln x ) > 0
ln x > 1
x > e
Answer:
Domain is: x ∈ ( e , + ∞ ).
A set of points is collinear if the points lie on the same straight line.
From the given figure,
A) Z, J, and C are not collinear
B) H, B, and C are collinear
C) H, B, and K are not collinear
D) Z, K, and R are collinear
Answer: B and D
Equation to find number:
- 3 = 
Number's value: n = 
Step-by-step explanation:
Let n be the unknown number.
The reciprocal basically makes the number (n in this case) a fraction. So, that being said, the reciprocal of n would be
.
The difference of three and the reciprocal of a number (
) would be
- 3.
The quotient of 20 and the number (n) would be
.
So, with this information we've gathered so far, we can come up with an equation to find what the number equals.
Equation:
- 3 = 
To find what the number equals we must solve the equation.
I believe the answer is
2 and 1/5
