The only way to check which one is the correct answer is to perform each set of transformations and check which one is the correct one. First, note that the initial position of the smiley face is the third quadrant. So, we will first apply vaguely the transformations to check to which one is the smiley face located in the first quadrant once we are done with the transformations.

So, let us analyze each set of transformations separately.

Option A

After reflexing over the x axis, the smiley face position would be

so, once rotated 270° counterclockwise, the position of the smiley face would be

so option A is not the correct answer

Option B

if we rotate 270° counterclockwise, the smiley face's position would be

and by translating 8 units to the right, it would be

so option B is the correct answer

Answer:

  (c)  corresponding angles

Step-by-step explanation:

You want to know the description of the marked angles in the given diagram.

Interior angles are between the "parallel" lines. Angle 5 is interior, but angle 1 is not, so they cannot be described as interior angles.

Exterior angles are both outside the "parallel" lines. Angle 1 is exterior, but angle 5 is not, so they cannot be described as exterior angles.

Corresponding angles are both in the same direction from the point of intersection of the "parallel" lines with the transversal. Here, both angles 1 and 5 are "northwest" of the intersection point, so are corresponding angles.

Alternate angles are on opposite sides of the transversal. Consecutive, or same-side, angles are on the same side of the transversal. Angles 1 and 5 are not alternate angles, as they are both on the same side of the transversal.

cos(25)= adjacent/hypotenuse

cos(25)= adjacent/48

adjacent= 48 * cos(25)

tan(59) = opposite/adjacent

tan(59) = x / 48 * cos(25)

x = 72.4

Step-by-step explanation:

You have found a used car and your parents have agreed to pay the first $750 for you. You have a summer job mowing yards for $25 per yard. Write and inequality that will calculate the number of yards (y) you will have to mow to get to at least the cost (C) of the car.

25y + 750 = C

If the car cost a total of $4500 how many yards will you have to mow?

25y + 750 = 4,500

subtract 750 from both sides:

25y + 750 - 750 = 4,500 - 750

25y = 3,750

divide both sides by 25:

25y/25 = 3,750/25

y = 150

Must mow 150 yards.

check:

25(150) + 750 = 4,500

3,750 + 750 = 4,500

4,500 = 4,500

To calculate (f g)(-1), we use the definition:

This is true if x is defined for f and g. Now, for our problem:

We can generate congruent shapes by combining the three types of transformations: rotations, reflections, and translations. Actually, using a combination of one or more of these three transformations, any pairs of congruent shapes can be matched to one another.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

Given Data

We now understand that the size and shape of the figures are preserved during stiff transformations (reflections, translations, and rotations). Pre-image and image are always congruent with one another.

Series of transformation Matt can perform:

Reflection (Flip)

Because the equivalent points from the pre-image to the image remain at the same distance from the line of reflection, a reflection maintains its original shape.

Rotations as a Transformation of Congruence

A rotation is when a figure turns. Although the figure is the same size and shape, it appears to have fallen over. A clock is a fantastic example of a rotation in the real world. Every hour or every day, the connecting arms of a clock revolve around its central point. The degree of rotation is used to characterize a rotation; popular rotations include 90 degrees, 180 degrees, and 270 degrees. The figure returns to its original position after a full 360-degree spin. A rotation must additionally include the direction, either clockwise or counterclockwise. A rotation's degree amount and direction can be computed using this information.

Congruence transformation through translation

When we move an object or shape from one location to another without changing its size, shape, or orientation, we call that movement a translation. A translation, often known as a slide, involves moving each point on an object or shape by the same amount and in the same direction.

If the length of a side of cube is "s", then total edge length (E = 12s), total surface area (A = 6s²) and Volume (V = s³).

As per the question statement, the length of a side of cube is "s".

We are required to write down the equations for total edge length "E", total surface area "A" and Volume "V" of the cube with respect to "s".

To solve this question, we need to know a couple of basic structural properties of a cube, that is,

There are 12 edges in a cube, all of equal length,

And, there are 6 faces in a cube, all of equal surface area.

[A reference image is attached hereby for better understanding;

The 12 edges of the cube are: AB, BC, CD, AD, CG, DH, BF, AE, EF, FG, GH and EH,

And, the 6 Faces of the cube are: ABCD, ABEF, CDGH, BCFG, ADEH and EFGH]

Therefore, total edge length (E) = (12 * s) = 12s,

Or, (E = 12s)

Total surface area (A) = [6 * (s)²] = 6s²,

Or, (A = 6s²)

[Since, area of a square of edge length "s" = s², and every face of a cube is a square]

Finally, Volume (V) of the cube = [s * s * s] = s³,

Or, (V = s³).

If a bicycle has a listed price of $522.95  before tax and the sales tax is 7.75%, then the total cost of the bicycle with sales tax included is $563.47

The listed price of bicycle = $522.95

The sales tax percentage = 7.75%

We know

C = p(t×p)

Where C is the total cost

p is the listed price

t is the sales tax percentage

Substitute the values in the equation

C = 522.95+((7.75/100)×522.95)
= 522.95+40.53

= $563.47

Hence, if a bicycle has a listed price of $522.95  before tax and the sales tax is 7.75%, then the total cost of the bicycle with sales tax included is $563.47

Step-by-step explanation:

(7·49.95 + 162.38)/2465 = 0.2077

Answer: you can get the full fraction by multiplying 6x3 which is 18 so then you add 18 and 2 and you get 20 so now the fraction is 20/3

Answer: Europe quit buying crops which left the united states with a surplus of crops

Step-by-step explanation:

the probability of both is the one they share

There is a mound of 2000 pounds of gravel in a quarry

Quantity of gravel added in the mound throughout the day = 400 pounds

Quantity of orders sold from the mound = 600*2 = 1200 pounds

Quantity of gravel left in the mound at the end of the day = 1200 pounds

Let g represent the pounds of gravel in the quarry

Formulating the equation we get the following:

Mounds of gravel in the quarry + Gravel added in the mound - Gravel sold from the mound = Gravel left at the end of the day

g + 400 - 600(2) = 1200

g + 400 - 1200 = 1200

How to solve a quadratic equation by substitution?
The equation is first transformed into a more familiar form. Replace the substitutions with the original variables after factoring the problem. The difference of squares equation is used to finish the factorization and locate the answers for x.

Given, the equation for solving is: (x + 2)² - 2(x + 2) - 15 = 0 --(i)
Let in the equation, y = x + 2 --(ii)
Equating (i) and (ii), we get:
y² - 2y - 15 = 0 ⇒ y² - 5y + 3y - 15 = 0 ⇒ y(y - 5) + 3(y - 5) = 0
⇒ (y + 3)(y - 5) = 0 ⇒ y = -3, 5 (by solving the equations)
Thus, from (ii) and value of y obtained above, we get,

P(X = x) = [tex]C_{n,x}[/tex] . [tex]p^{x}[/tex] .[tex](1-p)^{n-x}[/tex]

[tex]C_{n,x}[/tex]= n!/ x!(n - x)!

The parameters are:

n is the number of trails.

x is the number of successes.

p is the probability of success on a single trial.

In this problem:

43% say job applicants should follow up within two weeks, thus p = 0.43

6 managers are selected, thus n= 6.

The probability that at least 3 of them say job applicants should follow up within two weeks is P(X≥ 3), which is given by:

P(X ≥3) = 1 -P(X < 3)

In which:

P(X < 3 ) = P(X = 0) + P(X = 1) + P(X = 2)

Then:

P(X = x) = [tex]C_{n,x}[/tex]. [tex]p^{x}[/tex]. [tex](1-p)^{n-x}[/tex]

P(X = 0) = [tex]C_{6,0}[/tex] [tex](0.43)^{0}[/tex]. [tex](0.57)^{6}[/tex] = 0.0342

                                                             = 0.0796

P(X≥3) = 1 - P(X<3) = 1- 0.0796 = 0.9204
