Answer:b

Step-by-step explanation:

 Option A. Pentagon W'F'N'S'C' is larger than pentagon WFNSC because the scale factor is greater than 1.

          (x, y) → (kx, ky)

Given in the question,

        (x, y) → (3x, 3y)

Here, k > 3 which shows that the image will be larger than the preimage.

      Therefore, pentagon W'F'N'S'C' will be larger than pentagon WFNSC because the scale factor is greater than 1.

      Hence, Option A will be the answer.

Answer:

h(x) = (1/4)x - 2 which is choice A

Step-by-step explanation:

Replace f(x) with y. Then swap x and y. Lastly, solve for y to get the inverse.

f(x) = 4x+8

y = 4x+8

x = 4y+8

x-8 = 4y

4y = x-8

y = (x-8)/4

y = x/4 - 8/4

y = (1/4)x - 2

h(x) = (1/4)x - 2

Step-by-step explanation:

The lines represent the lines of symmetry where the image can be reflected upon. Hence it is reflectional.

The dot in the middle of the image tells us that the image can be rotated about the dot to produce the exact same image. Hence it is rotational.

The answer is both rotational and reflectional.

Answer:

I broke it to phrases. Make sure to read both.

It is rotational symmetry. This is because rotational symmetry means it is able to be rotated, and looks the same. This is true with this figure. The lines demonstrate that it is an equal dimensioned 2D shape.

It is ALSO reflection symmetry because this means it can be split through the center and looks exactly the same, as if it was a reflection. This is true here too because it has the same amount of lines split through the same angle on each side making it equal. You can also see a line already going through the shape, and as you can see if you look at see side it looks equal, like a reflection.

The answer is D.

Step-by-step explanation:

Answer:

R=10,244 Lb

Step-by-step explanation:

In order to solve this problem, we can start by drawing the situation. (See attached picture).

We can look at the forces applied by the trucks as vectors, so in this case, in order to find the resultant force, we can add the two vectors. You can do so by drawing one force after the other and join the start of the first force with the end of the second force to form a triangle. The missing side will be the resultant force. In that triangle I drew there, the inner angle will be found by subtracting 180°-110°=70°

In this case we can find the resultant force by using the law of cosines:

[tex]A^{2}=B^{2}+C^{2}-2AB cos \alpha[/tex]

so we can use the data given by the problem:

[tex]R^{2}=T_{1}^{2}+T_{2}^{2}-2T_{1}T_{2} cos \alpha[/tex]

so we can solve this for R, so we get:

[tex]R=\sqrt{T_{1}^{2}+T_{2}^{2}-2T_{1}T_{2} cos \alpha}[/tex]

now we can substitute:

[tex]R=\sqrt{(10,000Lb)^{2}+(7,500Lb)^{2}-2(10,000Lb)(7,500Lb) cos (70^{0})}[/tex]

which yields:

R=10,244Lb

Step-by-step explanation:

Took the test

Answer:

0.15

Step-by-step explanation:

Given

[tex]Necklaces = 20[/tex]

Represent the probability of pulling out silver with p; So:

[tex]p = 0.85[/tex]

Required

Determine the probability of not pulling silver

This question is to test probability complements

And the complement rule of probability states that:

[tex]p + q = 1[/tex]

Where q and p are opposites. In other words:

q = probability of not pulling out silver

Substitute 0.85 for p in [tex]p + q = 1[/tex]

[tex]0.85 + q = 1[/tex]

Make q the subject

[tex]q = 1 - 0.85[/tex]

[tex]q = 0.15[/tex]

Hence, the required probability is 0.15

Answer:

The value of b is 5 if the parallelogram is a rectangle

Step-by-step explanation:

Mathematically, the diagonals of a rectangle are equal in value

Thus, for the given expressions to represent the diagonals of a rectangle, the two must be equal

To get the value of b that makes the two equal, we simply equate the two expressions

We have this as;

10/12(24b/5 - 36/5) = 2/3 (3b + 6)

opening the brackets, we have;

4b - 6 = 2b + 4

4b - 2b = 4 + 6

2b = 10

b = 10/2

b = 5

Answer:

19 boxes of tomatoes

Step-by-step explanation:

If she starts with 7 boxes of tomatoes and she picks 2 more each day for 6 days then you can multiply 2 by 6 and get 12 tomatoes then you add the 7 boxes she originally started with and you get 19 boxes of tomatoes.

The number of boxes Nancy had after 6 days is 19, the equation representing the given phrase is y = 2x + 7, and the graph is attached below.

A collection of objects is arranged in a graph, where some object pairings are conceptually "linked." Each pair of connected vertices is referred to as an edge, and the objects are represented by mathematical abstractions known as vertices.

Given:

Nancy has 7 boxes of tomatoes,

Each day, she picks another 2 boxes,

The equation which will represent the above phrase is shown below,

Total number of tomatoes = The number of tomatoes she already had + number of days × each day's tomatoes picked by Nancy,

Assume the total number is y and the number of days is x then,

y = 7 + 2 × x

y = 2x + 7

Put the value of x = 6,

y = 2 × 6 + 7

y = 12 + 7

y = 19

Thus, she has a total of 19 boxes of tomatoes after 6 days.

Let us rule out the first one. c+11 is not equivalent.

The second one does not work either because it is adding the two terms instead of multiplying.

The last one does not work either because again, it is adding.
