Answer:
f(x) = √7x
g(x) = 1/x -8
To find the domain of f º g we must first find f o g(x)
To find f o g(x) wherever you see x in f(x) replace it by g(x)
That's
f o g = √7(1/x-8)
= √7 / √x - 8
To find the domain equate the denominator to zero
That's
√x - 8 = 0
Square both sides
(√x - 8)² = 0²
x - 8 = 0
x = 8
The domain of f o g is x E R except 8
Hope this helps
Answer: Line segment.
Step-by-step explanation:
In geometry, a line is an undefined term in which an infinite number of points extending in opposite directions.
It has only one dimension.
When it has endpoints on both the sides, it is known that a line segment (which is an defined term).
Hence, If points A and B are connected by a series of points that extend infinitely in opposite directions, then AB is a line.
So, the term best describes the geometric figure: 'Line segment"

15
The volume of the cube is 15 hence it will take up 15 cubic units.
The like terms can be grouped by their variables and exponents. Let's do that.
Now, just add each group of like terms together by adding their coefficients.
Now, add all the terms together.
