Is there a single rigid motion that would map triangle WXY to triangle W"X"Y"'?

Answer:

Y=4 is a function

Step-by-step explanation:

And to me function is relation

Hope i got this right and have a great day :)

Answer: Yes

Step-by-step explanation:

Yes, y = 4, which is often written as f(x) = 4, is a function that means “take any input, and no matter what it is, produce an output of 4”.

Using the proportionality theorem, to find the values of x and y, we have:

a. x = 1.25; y = 1.75

b. x = 15; y = 4

c. x = 3; y = 2

According to the proportionality theorem, the side lengths of similar triangles have the same ratio, or are proportional to each other.

Using the proportionality theorem, we can find the following missing values of x and y.

a. (5 + x)/5 = 10/8 [proportionality theorem]

Cross multiply

8(5 + x) = (5)(10)

40 + 8x = 50

8x = 50 - 40

8x = 10

x = 10/8

x = 1.25

5/x = 7/y

Plug in the value of x

5/1.25 = 7/y

5y = 8.75

y = 1.75

b. x/5 = 18/6 [proportionality theorem]

6x = 90

x = 90/6

x = 15

12/y = 18/6

Cross multiply

18y = 72

y = 72/18

y = 4

c. x/6 = 1.5/3 [proportionality theorem]

3x = 9

x = 9/3

x = 3

y/4 = 1.5/3

Cross multiply

3y = 6

y = 6/3

y = 2

Step-by-step explanation:

The perfect square trinomial and binomial of the expression [tex]q^{2}[/tex] + [tex]\frac{5}{6}q[/tex] are  [tex]q^{2}[/tex] + [tex]\frac{5}{6}q[/tex] + [tex]\frac{25}{144}[/tex] and [tex](q + \frac{5}{12}) ^{2}[/tex]

Perfect squares are numbers or expressions that are the product of a number or expression multiplied to itself. 7 times 7 is 49, so 49 is a perfect square. x squared times x squared equals x to the fourth, so x to the fourth is a perfect square.

[tex]q^{2}[/tex] + [tex]\frac{5}{6}q[/tex] expression can be made into a perfect square by adding the square of half the coefficient of q

coefficient of q = [tex]\frac{5}{6}[/tex]

Half of [tex]\frac{5}{6}[/tex] = [tex]\frac{5}{12}[/tex]

square [tex]\frac{5}{12}[/tex] we have [tex](\frac{5}{12}) ^{2}[/tex] which becomes [tex]\frac{25}{144}[/tex]

so the perfect square trinomial = [tex]q^{2}[/tex] + [tex]\frac{5}{6}q[/tex] +  [tex]\frac{25}{144}[/tex]

the binomial is  [tex](q + \frac{5}{12}) ^{2}[/tex]

Required equation of line in slope intercept form

y = 4x - 7

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan \theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Slope of the line = 4

y - intercept of the line = -7

The line passes through (0. -7)

Equation of the required line

y - (-7) = 4(x - 0)

y + 7 = 4x

y = 4x - 7

Judgement sampling is not a probability sampling technique

Probability sampling is a technique in which the researcher chooses samples from a larger population using a method based on probability theory. For a participant to be considered as a probability sample, he/she must be selected using a random selection.

The most critical requirement of probability sampling is that everyone in your population has a known and equal chance of getting selected.

1. Simple random sampling, as the name suggests, is an entirely random method of selecting the sample. This sampling method is as easy as assigning numbers to the individuals (sample) and then randomly choosing from those numbers through an automated process. Finally, the numbers that are chosen are the members that are included in the sample.

2. Stratified random sampling involves a method where the researcher divides a more extensive population into smaller groups that usually don’t overlap but represent the entire population. While sampling, organize these groups and then draw a sample from each group separately.

3. Random cluster sampling is a way to select participants randomly that are spread out geographically. For example, if you wanted to choose 100 participants from the entire population of the U.S., it is likely impossible to get a complete list of everyone. Instead, the researcher randomly selects areas (i.e., cities or counties) and randomly selects from within those boundaries.

From the above explanation, cluster sampling, simple random sampling and stratified random sampling are types of probability sampling except for judgement sampling.

To have the same price, 40 stickers will have to be ordered and the equation is 16 = 0.40p.

What is the equivalent equation?

Equivalent equations are algebraic equations with identical solutions or roots. Adding or subtracting the same number or expression from both sides of an equation yields an equivalent equation. An equivalent equation is created by multiplying or dividing both sides of an equation by the same non-zero number.

We have,

for company A :

Design Fee = $30

Costvper sticker = $0.80

for company B :

Design Fee = $14

Cost per sticker = $1.20

Let the number of stickers = p

Total cost of company A = 30 + 0.80p

Total cost of company B = 14 + 1.20p

For the cost to be the same :

Company A = Company B

30 + 0.80p = 14 + 1.20p

Collect like terms :

30 - 14 = 1.20p - 0.80p

16 = 0.40p

p = 16/0.40

p = 40 stickers

Therefore, to have the same price, 40 stickers will have to be ordered and the equation would be 16 = 0.40p.

Therefore the total surface area of the cylinder is 157 square feet.

The surface area of a solid item is a measurement of the total volume that the surface of the thing occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more complicated than the definition of arc length for one-dimensional curves.

The number of tiles that would be required to cover a floor that is 288 square feet is 512.

According to the question,

We have the following information:

Area of the tile = 9*9 square inches

Area of the tile = 81 square inches

Area of the floor = 288 square feet

So, we will convert the area of the floor from square feet to square inches.

We know that 1 feet = 12 inches.

So, we have the following expression:

Area of the floor = (288*12*12) square inches

Area of the floor = 41,472 square inches

Number of tiles required to cover the floor = area of the floor/area of the tile

Number of tiles required to cover the floor = 41,472/81

Number of tiles required to cover the floor = 512

Hence, the number of tiles that would be required to cover a floor that is 288 square feet is 512.

Answer:

4) Melody is 9 and her sister is 24

5) The numbers are 3 and 9

6) 14 feet per second

Step-by-step explanation:

Questions 4

There is a lot going on here.  This is probably hard to follow.  If it is, it is me and not you.

Let m = Melody and s = sister

m - 4 = 1/4(s-4)                     m + 6 = 1/2(s + 6)  Clear the fractions

4m - 16 = s -4                        2m -s = -6

Multiple the second equation by -1 and add together

4m - s = 12

-2m + s = 6

2m = 18  Divide both sides by 2

m = 9  Substitute this in to find the sister's age

2m + 12 = s + 6

2(9) +12 + s + 6

18 + 12 = s + 6

30 = s + 6  Subtract 6 from both sides

24 = s

Questions 5

x + y = 12              x = 5y - 6

Plug in 5y - 6 in the first equation for x

5y - 6 + y = 12  Combine like terms

6y - 6 = 12  Add 6 to both sides

6y = 18  Divide both sides by 6

y = 3

x + y = 12

3 + y = 12  Subtract 3 from both sides

y = 9

I am little confused by this because it says, "The value of the number..."  What number are they referring to?

Question 6

To find the rate taking into consideration the walkway rate:

[tex]\frac{48}{3}[/tex] - w  Which is equivalent to 16 - w

[tex]\frac{24}{2}[/tex] + w  Which is equivalent to 12 + w

Set these expression equal to each other and find the rate of the walkway

16 - w = 12 + w  Add w to both sides

16 = 12 + 2w  Subtract 12 from both sides

4 = 2w  Divide both sides by 2

2 = w

The rate of the walkway is 2 feet per second.  Subtract that from 16 or add is to the 12 to get 14 steps per second.
