Given that 
and 
, we can say the following:
Now, remember what happens if we have a negative square root: it becomes an imaginary number. We don't want this, so we want to make sure whatever is under a square root is greater than 0 (given we are talking about real numbers only).
Thus, let's set what is under both square roots to be greater than 0:
Since both of the square roots are in the same function, we want to take the union of the domains of the individual square roots to find the domain of the overall function.
Now, let's look back at the function entirely, which is:
Since 
is on the bottom of the fraction, we must say that 
, since the denominator can't equal 0. Thus, we must exclude 
from the domain.
Thus, our answer is Choice C, or 
.

Answer:
6 meters
Step-by-step explanation:
Every 7 floors, it goes up by 22.4 meter intervals.
Let's count down,
the 7th floor would be 50.8 - 22.4, which is 28.4.
the 0th floor would be 28.4 - 22.4, which is 6.
Answer and Step-by-step explanation:
Solution:
Given:
Assume that 46% of consumers are comfortable to deliver their purchase.
Five consumers randomly selected.
Exactly three of them are comfortable with delivery by drones.
Identify the value of n, x, p?
Probability of success on any one trial = 46% = 0.46
Probability of failure on any trial = q = 1-p
= 1- 0.46
= 0.54
The number of trial = n = 5
The number of comfortable consumers =x = 3
n represent the number of subject included.in this question, there are five consumers randomly selected.
X represents the number of success. In question, there are exactly three consumers that are comfortable with delivery by drones.
P represents the probability of success, and q represent the probability of failure.
Hence,
n = 5
x= 3
p = 0.46
q= 0.54
