Answer:

Step-by-step explanation:
The domain of a function is all of the values that
can be under that specific function. In this case, we're asking what values of
allow
to exist.
In order for square roots to exist, the quantity under the square root must be greater than or equal to
, because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for
:

Solving this inequality, we get:

(Subtract
from both sides of the inequality to isolate
)
(Multiply both sides of the inequality by
to get rid of
's coefficient)

Answer:
the number is 126
Step-by-step explanation:
1) multiply each side by 32: (n-2) / 32 = 4
2) subtract 2 from each side: n-2 = 128
3) n = 126
4:3
x:39
We need to find what 3 was multiplied by to get 39:
39/3 = 13.
Now multiply 4 by this number
4*13 = 52

Answer:
The answer is below!!
Step-by-step explanation:
The formula used to find the area of a circlular sector - a pie-shaped part of a circle. ... π. 4. 2. ·. 86. 360. = 12.01. What the formulae are doing is taking the area of the whole ... So for example, if thecentral angle was 90°, then the sector would have an area equal to one ... r is the radius of the circleof which the sector is part.
