The value of h(f(x)) is x which is the C option in the question.
It is given in the question that h(x) is the inverse of f(x).
We have to find the value of h(f(x)).
If h(x) is the inverse of f(x), we can write is as:-
[tex]f^{-1}(x)=h(x)[/tex]
Hence,
h(f(x)) = [tex]f^{-1}(f(x))=(f^{-1}f)(x) = x[/tex]
Hence, the value of h(f(x)) is x.
Inverse function
An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by ‘f’ or ‘F’, then the inverse function is denoted by f-1 or F-1.

The measure of an angle is 136.8° more than the measure of a supplementary angle. What is the measure of each angle?
If the measure of an angle is 136.8 degrees more than the measure of a supplementary angle, then the measure of each angles are 21.6 degrees and 158.4 degrees
The supplementary angles are the angles whose measure add up to 180 degrees.
If x and y are supplementary angles
x + y = 180 degrees
Here the measure of an angle is 136.8 degrees more than the measure of supplementary angle.
So one angle will be x and other angle will be x+136.8
Then the equation will be
x + x+136.8 = 180
2x+136.8 = 180
2x = 43.2
x = 43.2/2
x = 21.6 degrees
Other angle is
21.6+136.8 = 158.4 degrees
Hence, if the measure of an angle is 136.8 degrees more than the measure of a supplementary angle, then the measure of each angles are 21.6 degrees and 158.4 degrees

a. if a quadrilateral has four right angles, then then it is a square
b. if a quadrilateral is a square, then it has four right angles
c. if a quadrilateral is a square, then it is a rectangle
Using the law of syllogism, the conclusion is given as follows:
c. if a quadrilateral is a square, then it is a rectangle.
Law of SyllogismThe Law of Syllogism is a logic axiom which states that if the conditional statements p -> q and q -> r are true, the conditional statement p -> r is also true, basically applying the transitive property.
In the context of this problem, the statements are given as follows:
Statement p: Quadrilateral is a square.Statement q: Quadrilateral has four right angles.Statement r: Quadrilateral is a rectangle.Hence the conclusion is:

$40,000 and over 35 37
Group of answer choices
a.35
b.90
c.160
d.75
The percentage of graduates from University A having income under $20,000 is 22%.
Percentage may be defined as the fraction which we get after dividing an entity from total number multiplied by 100. We have the total number of students in university A as 160. Now, we divide 35 that is the number of students who have an income under $20,000 in university A by 160 that is the total number of students in university A. We get the percentage as
P = (35/160) × 100
P = 0.218 × 100
P = 21.9 %
rounding off to nearest we get percentage as 22 %.

Answer:
Below in bold.
Step-by-step explanation:
Using the Cosine Rule:
a^2 = b^2 + c^2 - 2bc cos A
10^2= 11^2 + 13^2 -2.11.13 cos A
cos A = (11^2 + 13^2 - 10^2) / (2*11*13)
= 0.66434
m < A = 48.368 degrees
= 48.37 degrees to 2 D. P's.
By the Sine Rule:
a / sin A = b / sin B
10 / sin 48.368 = 11 / sin B
sin B = 11 * sin 48.368 / 10
= 0.82217
m < B = 55.303

For z varies jointly with x and y. When x=5 and y=4, z=12.
a. Equation that models the relationship is z=(3/5)xy.
b. When x=15 and y=2 then z=18.
As given,

Which graph shows a proportional relationship between x and y?
The graph C shows the proportional relationship between x and y.
What is meant by the term proportional relationship?A proportional relationship is defined as "y varies proportionally with x" or "y is directly proportional to x."
This implies that as x increases, y increases, and vice versa—and that the ratio among them always remains constant.The proportional relationship equation's graph is a straight line that follows the origin.Proportional relationships always are represented by equations of the form y=kx, in which k is the proportionality constant. That is, the connection between x and y always is multiplicative, with no additions or subtraction.For the given question;
The graph of the proportional relationship are given.
For the graph C, the relation tween x and y is said to be proportional because when the value of x increases the value of y decreases and also this line passes from the origin.
