Answer:
The price of a piece of cloth and length of cloth.
Step-by-step explanation:
A function must be measurable, attainable, and reasonable and the variables must complement each other
Measuring the distance to and time spend at school doesnt complement each other
The price of a movie ticket doesn't change based on height
Mowing a lawn doesnt matter how old you are
The price of cloth can change based on how long or short the cloth is.Shorter clothes are cheaper, while Longer clothes are more expensive.
Answer:
The example of a function is:
The price of a piece of cloth and the length of the cloth.
Step-by-step explanation:
We know that a function is a relation in which each element of a set is mapped to a single element of the other set.
i.e. an element has just one image.
1)
The time it takes to mow a lawn and the age of the person mowing the lawn.
This is not a example of function since, the time taken by two person's of different age may be same to mow a lawn.
This means that there is more than one image of a single element i.e. time.
2)
The distance to school and the time you spend at school.
The time one spend at school at different days may be different even if the distance to school is same.
3)
The price of a movie ticket and the height of the customer.
Two person's with different height will buy a movie ticket at the same cost.
Hence, this relation won't be a function.
4)
The price of a piece of cloth and the length of the cloth.
As we know that the price of a cloth is fixed according to the length.
Hence, the relation is a function.
( As corresponding to each price we have a unique length if a piece of clothing )

To change the weight of kilograms into pounds, multiply the weight in kilograms by ____________
To change the weight of kilograms into pounds, multiply the weight in kilograms by 2.2
According to the conversion systems, 1 kg = 2.2046 lbs
To facilitate conversion on a pen-paper basis we cannot use 2.2046 whole.
Hence we generally consider 1 k = 2.2 pounds.
The symbol for pounds is lbs and for kilograms is kg.
Now, 1 kg is 2.2 lbs
2 kg = 1 kg + 1 kg
= 2.2 lbs + 2.2 lbs
= 4.4lbs = 2 X 2.2
3 kg = 1 kg + 2 kg
= 2.2 lbs + 4.4 lbs
= 6.6 lbs. = 3 X 2.2
Hence we can see that for all these numbers we can multiply 2.2 to the given weight in kg to get the pounds form.

Solve for x.
2(x−3 1/2)=10 3/4
Enter your answer as a mixed number in simplest form in the box.
Answer:
x = 71/8
Step-by-step explanation:
Solve for x:
2 (x - (3 + 1/2)) = 10 + 3/4
Put 3 + 1/2 over the common denominator 2. 3 + 1/2 = (2×3)/2 + 1/2:
2 (x - (7/2)) = 10 + 3/4
2×3 = 6:
2 (x - (1/2 6 + 1/2)) = 10 + 3/4
6/2 + 1/2 = (6 + 1)/2:
2 (x - (7/2)) = 10 + 3/4
6 + 1 = 7:
2 (x - 1/2 7) = 10 + 3/4
Put each term in x - 7/2 over the common denominator 2: x - 7/2 = (2 x)/2 - 7/2:
2 ((2 x)/2 - 7/2) = 10 + 3/4
(2 x)/2 - 7/2 = (2 x - 7)/2:
2 (1/2 (2 x - 7)) = 10 + 3/4
(2 (2 x - 7))/2 = 2/2×(2 x - 7) = 2 x - 7:
(2 x - 7) = 10 + 3/4
Put 10 + 3/4 over the common denominator 4. 10 + 3/4 = (4×10)/4 + 3/4:
2 x - 7 = ((4×10)/4 + 3/4)
4×10 = 40:
2 x - 7 = 40/4 + 3/4
40/4 + 3/4 = (40 + 3)/4:
2 x - 7 = ((40 + 3)/4)
40 + 3 = 43:
2 x - 7 = 43/4
Add 7 to both sides:
2 x + (7 - 7) = 43/4 + 7
7 - 7 = 0:
2 x = 43/4 + 7
Put 43/4 + 7 over the common denominator 4. 43/4 + 7 = 43/4 + (4×7)/4:
2 x = (43/4 + (4×7)/4)
4×7 = 28:
2 x = 43/4 + 28/4
43/4 + 28/4 = (43 + 28)/4:
2 x = ((43 + 28)/4)
43 + 28 = 71:
2 x = 71/4
Divide both sides by 2:
x = (71/2)/4
4×2 = 8:

A playground slide is 14. 5 feet long with an 8. 5-foot tall ladder. A playground slide is 14. 5 feet long and has an 8. 5 foot tall ladder. The angle formed by the ladder with the ground is 90 degrees. The angle formed by the slide with the ground is x. What is the measure of the angle that the slide makes with the ground, x, to the nearest degree?.
The angle made by the slide of length 14.5 ft with the ground is 36°
The length of the slide = 14.5ft
The length of the ladder = 8.5 ft
The angle made by the ladder and ground = 90°
The angle formed by the slide can be found using the Pythagoras theorm,
sinθ = O / H
where θ is the angle made by the slide
O is the side opposite to the angle of the slide
H is the side that is hypotenuse with the slide
Let us rearrange the above equation in order to get the angle of the slide,
θ = sin⁻¹ (O/H)
Let us substitute the known values in the above equation, we get
θ = sin⁻¹ (8.5 / 14.5)
= sin⁻¹ (0.586)
≈ 36°
Thus, the angle of the slide is 36°

-5x+12y=8
2x-8y=0
Answer:
x = -4
y = -1
Step-by-step explanation:
-5x+12y=8
2x-8y=0
We multiply the first equation by 2 and the second equation by 5
-10x + 24y = 16
10x - 40y = 0
-16y = 16
y = -1
Now put -1 back in for y and solve for x
-5x + 12(-1) = 8
-5x - 12 = 8
-5x = 20
x = -4
Let's check
-5(-4) + 12(-1) = 8
20 - 12 = 8
8 = 8
So, x = -4 & y = -1 is the correct answer.

If a function yields the result y, then its inverse function, denoted by the symbol , will return the value x.
What is meat by inverse of the function?A function's output is returned when its inverse function does the same action variable. The inverse function of a function, or f-1(y), will return the value x if the function f(x) produces the output y.A function that reverses the action of a function, or f, is known as its inverse in mathematics.
Here,
A function that reverses the effects of another function is said to have an inverse. If y = f(x), then x must always equal g, then a function g is the inverse of a function f. (y). Application of f followed by application of g is equivalent to doing nothing, in other words. As g(f(x)) = x, this can be expressed in terms of the relationship between f and g.
Because they allow for the reversal of mathematical operations, inverse procedures are crucial for solving equations (e.g. logarithms, the inverses of exponential functions, are used to solve exponential equations).

Step-by-step explanation:
x^2 = x (2x - 4) + y
Let's simplify it and we get
x^2 = 2x^2 - 4x + y
Now, we want to get the y by itself
x^2 = 2x^2 - 4x + y
-x^2 = -4x + y
-x^2 + 4x = y
So, our answer is y = −x^2 + 4x
What happens when you take the absolute value of a complex number?
The origin in the complex plane is represented by the number 0. Therefore, the separation between a complex number and the complex plane's origin (zero) equals its absolute value.
What happens when you calculate a number's absolute value?A number, variable, or expression is enclosed in two vertical bars to represent an absolute value in mathematics, as in the following example: A number's absolute value is always either positive or zero when calculated. The absolute value remains the same whether the initial value is already positive or zero.The origin in the complex plane is represented by the number 0. Therefore, the separation between a complex number and the complex plane's origin (zero) equals its absolute value.You won't have a solution if your absolute value expression is set to a negative quantity.To learn more about absolute value refer to:
