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:
Hey there!
Angles in a triangle add to 180 degrees.
Thus, we have 29+65, which is 94, and we subtract 94 from 180 to get 86.
Supplementary angles are also 180 degrees, so 180-86=94.
Thus, angle 1 is 94 degrees.
Hope this helps :)
Find 'per hour' here based on the above information.
10 1/2 divided by 3/4
10.5 ÷ 0.75 = 14
14 windows can be washed in one hour is the answer.
