Answer:
Step-by-step explanation:
We are given the square root function below:
Recall that domain is the set of all x-values and that a number inside the square root cannot be negative.
From the given square root function above, substituting x >= 2 gives a positive output. But if we substitute x < 2, evaluating the numbers inside result in negative number in the square root which does not exist in Real Number.
Hence,
And thus, the domain is
Since if x < a, the output would become an imaginary number.
From the given function,
From the form of sqrt(x-a) where domain is a-term which is 2.
Since a = 2, and thus
Answer:
475 will be rounded to 480, since 5 will always round up.

Answer:
r = 18
Step-by-step explanation:
Let d represent the number of districts. The given information lets us write two equations:
3d = 27 . . . . . the number of state senators
d +r = 27 . . . . the number of representatives
The first equation tells us ...
d = 27/3 = 9
The the second equation tells us ...
r = 27 -d = 27 -9 = 18
The number of at-large representatives is r = 18.
