What are trigonometric functions?
Trigonometric functions are also known as Circular Functions can be simply defined as the functions of an angle of a triangle. It means that the relationship between the angles and sides of a triangle are given by these trigonometric functions. The basic trigonometric functions are sine, cosine, tangent, cotangent, secant and cosecant.
The angles of sine, cosine, and tangent are the primary classification of functions of trigonometry. And the three functions which are cotangent, secant and cosecant can be derived from the primary functions

Where a 30° central angle in a circle is equivalent to π/6 radians, the complete sentence is given as: "the length of the arc intercepted by this central angle is 1/6 times the length of the circumference."
What is a central angle?It is to be noted that a central angle is an angle formed by two radii of a circle with its vertex at the center of the circle.
In this case, the Central angle 30° = π/6 radians.
Thus, the length of the arc intercepted by this central angle is 1/6 times the length of the circumference.
This is a mathematical rule that applies to any circle's center angle. It asserts that the length of an arc intersected by a central angle is proportional to the measure of the central angle and that the proportionality constant is the circumference of the circle divided by 360 degrees (or 2 π radians).
Hence, if a central angle is measured in degrees (or ϴ radians), the length of the associated arc is (θ/360) times the circle's diameter (or (ϴ/2) times the circle's circumference).
Hence, it is correct to state that: ""he length of the arc intercepted by this central angle is 1/6 times the length of the circumference."

Sans says that the temperature is negative three degrees below zero c. What is wrong with sana statement?
One thing that is wrong with Sana's statement is that it is repetitive as negative three degrees Celsius is already below zero.
What is a negative temperature ?When temperature is measured in degrees Celsius then it means that there are temperatures above 0 degrees Celsius and those that are below it. Those temperatures above 0 degrees Celsius are positive temperatures and those below zero degrees Celsius are negative.
These negative temperatures are used for places that are very cold and the colder a place is, the lower the temperature will be below zero. This therefore means that saying a temperature is negative and saying it is below zero is the same thing.
This means that Sana was wrong to say, " temperature is negative three degrees below zero " as they could have either said that the temperature was 3 degrees below zero or negative 3 degrees Celsius.

The measures on the isosceles triangles are given as follows:
9) <N = 42º. (option 3).
10) m < BCD = 130º. (option 4).
11) x = 28º. (option 2).
What is isosceles triangle?An isosceles triangle is a triangle that has two equal side lengths, hence it also has two equal angle measures.
For item 9, triangle LMO is isosceles, with two angles of 55º, hence the measure of angle M on triangle LMO is given as follows:
<M + 2 x 55 = 180
<M = 70º.
(sum of the internal angles of a triangle is of 180º).
On triangle NMO, the measure is given as follows:
<M = 180 - 70
<M = 110º.
(as it is external to the angle of triangle LMO).
Hence the measure of angle N is given as follows:
<N + 110 + 28 = 180
<N = 42º.
For item 10, the base angle is given as follows:
2x + 80 = 180
2x = 100
x = 50º.
Hence the exterior angle measure is given as follows:
m < BCD = 180 - 50
m < BCD = 130º.
(angle is supplementary with it's exterior).
For item 11, if AB = AC, the base angle is of (x + 20)º, hence the value of x is obtained as follows:
3x + 2(x + 20) = 180
5x + 40 = 180
5x = 140
x = 140/5
x = 28º.

Note: If the number that you have is positive, put the answer in the format of 0.xxx. If the number
that you have is negative, then put the answer in the format of -0.xxx
The simplified inequality for this problem is given as follows:
0.65x - 0.35y + 0.65z ≥ 0.
Hence the value of A is of:
0.65.
How to simplify the inequality?The inequality for this problem is defined as follows:
(x + z)/(x + y + z) ≥ 0.35.
Cross multiplication would work in this case, as the right term is a constant, however if it was a rational expression it would not work.
Thus the first step is leaving the right side as 0, as follows:
(x + z)/(x + y + z) - 0.35 ≥ 0.
Then the least common factor is applied to the left side, as follows:
[x + z - 0.35(x + y + z)]/(x + y + z) ≥ 0.
Applying the distributive property and combining the like terms, we have that:
(0.65x - 0.35y + 0.65z)/(x + y + z) ≥ 0.
Now cross multiplication can be applied, hence the simplified inequality is:
0.65x - 0.35y + 0.65z ≥ 0.
The coefficient A has a value of 0.65, which is the term that multiplies x.

The sides of △ABC have lengths of 6.4, 8, and 11.4. An angle bisector meets the side of length 11.4.
What are the lengths of x and y? Round your answers to the nearest hundredth.
The values of the lengths of x and y in the triangle are x = 5.06 and y = 6.33
How to determine the values of the lengths of x and yFrom the question, we have the following parameters that can be used in our computation:
The sides of △ABC have lengths of 6.4, 8, and 11.4. An angle bisector meets the side of length 11.4.This means that
x + y = 11.4
The theorem of angle bisector states that:
"The angle bisector of a triangle divides the opposite side into two parts proportional to the other two sides of the triangle"
This means that
a/b = x/y
In this case, we have
6.4/8 = x/y
So, we have
0.8 = x/y
Make x the subject
x = 0.8y
Substitute x = 0.8y in x + y = 11.4
0.8y + y = 11.4
Evaluate
1.8y = 11.4
Divide by 1.8
y = 6.33
Recall that
x = 0.8y
So, we have
x = 0.8 * 6.33
Evaluate
x = 5.06
Hence, the lengths are x = 5.06 and y = 6.33

The estimated arrival time of the train in San Diego is 4:16 PM.
To find the arrival time, we must add the length of the trip to the starting time.
The trip is 4 hours and 26 minutes long, so we must add 4 hours, which is equivalent to 240 minutes, and 26 minutes to the starting time of 11:50 AM.
This results in a final time of 4:16 PM.

What do you mean by function?In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. The most common symbol for a function is an arrow with the letter "f" written above it (f: X → Y), where "X" is the set of inputs and "Y" is the set of outputs. A function assigns a unique output to each input, and the inputs and outputs can be any mathematical objects, such as numbers, vectors, or polynomials.
How to find inverse of function?To find the inverse of a function, you first need to make sure that the function is invertible, which means that it has a unique inverse. A function is invertible if and only if it is a bijection, that is, it is both a function (meaning that it assigns a unique output to each input) and a surjection (meaning that every element of the output set is the image of at least one element of the input set) and an injection (meaning that no two different inputs have the same output). Once you have verified that the function is invertible, you can find its inverse by "reversing" the input and output.
f(x) = -4/3x+2/3
replacing input and output,
x = -4/3y + 2/3
3x-2 = -4y

In order to solve the triangle, you need to use the Law of Sines and the Law of Cosines. The Law of Sines states that the ratio of the sides to their opposite angles is constant, while the Law of Cosines states that the sum of the squares of the sides of a triangle equal the square of the hypotenuse. Using these two laws, you can calculate the angles and side lengths of the triangle.

At the fast food restaurant, an order of fries costs $0.92 and a drink costs
$0.96. How much would it cost to get 2 orders of fries and 4 drinks? How
much would it cost to get f orders of fries and d drinks?
Total cost, 2 orders of fries and 4 drinks:
Total cost, f orders of fries and d drinks:
The cost of 2 orders of fries and 4 drinks is $5.68 and the cost to get f orders of fries and d drinks is $0.92f+0.96d
What is unit rate?When something is calculated on its one unit, then it is called its unit rate. for example: If 5 mangoes is of $50 then cost of 1 mango is 50/5 = 10 here $10 is unit rate for mangoes.
Given that, At the fast food restaurant, an order of fries costs $0.92 and a drink costs $0.96.
We have here unit rates of fries and drinks,
So, when 1 pack of fries costs $0.92, then cost of 2 pack of fries = 2×0.92 = $1.84
Similarly, when 1 drink costs $0.96, then the cost of 4 drinks = 4×0.96 = $3.84
Total cost = $5.68
Similarly, the cost to get f orders of fries = $0.92f
And, the cost of d drinks = $0.96d
Total cost = $0.92f+0.96d
Hence, we get the answer as = a) $5.68 and b) $0.92f+0.96d

The statements a, c and d are true.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
From the figure we understood that h is the height and r is the radius.
The volume of the cone is 1/3πr²h
V= 1/3πr²h
When volume is 47 then we need to find the height
47= 1/3π(3)²h
47=3×3.14h
47=9.42h
h=4.92=5
So if the volume is 47cm³ then the height of the cone is 5cm approximately is true
Now let us find the statement 2 is true or not
V= 1/3π(3)²(10)
V=3×3.14×10
V=94.2 cm³
So the second statement is not true
The equation V= 1/3π(3)²h is the volume of the cone and h=3V/π(3)² an be used to find the height of the cone is true.
Hence, the statements a, c and d are true.

Your friend incorrectly says the line m is parallel to line n when the measure angle X is 16. For which measure of angle x is line m parallel to line n? what was your friends likely mistake?
please guide me through this i’m lost on how to complete it
By the converse of the corresponding angles theorem, [tex]\boxed{x=74}[/tex].
The likely mistake is the assumption that the two labeled angles are complementary.
Answer:
See below
Step-by-step explanation:
Because lines M and N are parallel, then T is the transversal, which means that 74° and X° are corresponding angles and have the same angle measure of 74°. The friend probably thought 74° and X° were complementary angles, but this is not the case.
