if f(x) = x + 7 and g(x) = 1 / x - 13, whaf is the domain of (f°g)(x)?
Answers
Answer: Choice D) x can be anything but 13
========================================================
Explanation:
The domain of [tex](f \circ g)(x) = f(g(x))[/tex] is the same as the domain of g(x)
The domain for g(x) is [tex]\{x|x \ne 13\}[/tex] saying we can plug in any number we want as long as it's not 13. This is to avoid dividing by zero. The same domain applies for the composite function because
[tex]f(x) = x+7\\\\\\f(g(x)) = g(x)+7\\\\\\f(g(x)) = \frac{1}{x-13}+7\\\\\\(f \circ g)(x) = \frac{1}{x-13}+7\\\\\\[/tex]
and we can see that we still need to kick out x = 13 from the domain to avoid the division by zero issue.

The diameter of the sphere will be equal to 4.59 feet.
What is a sphere?
The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
Given that:-
The spheres cost $2 per square foot and Selim can spend $20 per sphere. What is the maximum diameter of the spheres he can purchase?The area of the sphere will be = 20 / 2 = 10 square feet
The diameter of the sphere will be calculated as:-
Area = 4 π r
10 = 4 π r
r = 10 / ( 4 π )
r = 0.79 feet
D = 2r = 2 x 0.79 = 1.59 feet
Therefore the diameter of the sphere will be equal to 4.59 feet.

[tex]1011.101_2[/tex]A normalized exponential form.In Computer technology, binary numbers like decimal numbers in mathematics can be written in an exponential form and it involves the use of powers of two (2) rather than powers of ten (10).
Additionally, all non-zero binary numbers have a unique normalized exponential form and their binary point must always appear before the first one (1) bit, which yields a unique integer (exponent) and a unique mantissa respectively.
Thus, the normalized exponential form for the given binary number is written as follows:

If H1(x) is the inverse of H(x) , what is the value of H1 (H(x)) ?
Answers
In the inverse function, if you feed in y, you get x
So basically if you take the inverse of the original function, you get back the original input.
Hence:
H^-1(H(x)) = x
Take this example:
H(x) = 3x
H^-1(x) = x/3
H^-1(H(7))
--> H(7) = 3(7) = 21
--> H^-1(21) = 21/3 = 7

I'm not sure what it means by "define the types of linear" (maybe theres a given function?), but to find the x intercept you need to make y 0. For example:
if we have a function
f(x) = 2x + 1
and we want to find the x intercept we substitute 0 to y
0 = 2x + 1
not
f(0) = ......
Answer:
To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’. How do you find the Y intercept in a word problem? When a word problem involves a constant rate or speed and a beginning amount, it can be written in slope-intercept form: y=mx+b.

The average salary for a first-year teacher is $27,989. If the distribution is approximately normal with a standard deviation of $3250. If the z-score is 0.34. What salary corresponds to the z-score
Answers
If needed, delete the comma and/or the dollar sign.
=========================================================
Work Shown:
mu = 27989 = population mean
sigma = 3250 = population standard deviation
z = (x-mu)/sigma
z*sigma = x-mu
x = z*sigma + mu
x = 0.34*3250 + 27989
x = 29,094
The salary of $29,094 corresponds to the z score of 0.34.
This indicates the salary $29,094 is exactly 0.34 standard deviation units above the mean.
