Angles 3x° and 60° are Corrosponding angles so they are equal:

[tex]3x = 60 \\ \frac{3x}{3} = \frac{60}{3} \\ x = 20[/tex]

Angles (5y-5)° and 135° are Cointerior so add to give 180°:

[tex]5y - 5 + 135 = 180 \\ 5y + 130 = 180 \\ 5y = 180 - 130 \\ \frac{5y}{5} = \frac{50}{5} \\ y = 10[/tex]

Explain in your own words why it takes more to prove quadrilaterals congruent. Include examples demonstrating how ""just angles"" or ""just sides"" is not enough.

Answers

Proving that quadrilaterals are congruent takes more because all quadrilaterals are polygons of four sides and they all have a sum angle of 360°

Meaning of Congruent quadrilaterals

A quadrilateral can be defined as a polygon shape that possesses four sides.

Congruent quadrilaterals are those quadrilaterals that are similar in sides and angles.

For example, a parallelogram needs to be proved by both the sides and the angles

2. Amber says that the data set is left-skewed because the box is farther to the left on the number line. Is she correct? Explain how you know.​

Answers

Answer:

Both are wrong

Step-by-step explanation:

Though the box is shorter on the left side, it doesn't mean there are fewer numbers. Box plot tells the range, and not the mode. The box plot tells us that the interquartile range is higher on the right side.

Amber is wrong since the box plot is right-skewed

We can conclude that:

1. Andrea is wrong, box plot doesn't imply mode.

2. Amber is wrong, the box plot is right-skewed.

What is a Box Plot?

A box plot shows how a data is distributed or spread out.

If a data distribution is right-skewed, the median which is indicated by the vertical line that divides the rectangular box would be closer to the lower end of the box, and also if it has a shorter whisker to the left.

Also, if a data distribution is left-skewed, the median would be closer to the upper end of the box, and also if it has a shorter whisker to the right of the box.

The box plot shown is right-skewed.

For what values of b will F(x) = logo x be a decreasing function?
A. b>0
B. 0 C. b< 0
D. O >b>-1

Answers

[tex]f(x) = \log_b(x)[/tex] is a decreasing function when [tex]0 < b < 1[/tex]

This is because we can use the change of base formula to say

[tex]\log_b(x) = \frac{\log(x)}{\log(b)}[/tex]

If b is between 0 and 1, not including either endpoint, notice how the log(b) term is negative.

For example, if b = 0.5, then log(b) = log(0.5) = -0.301 approximately. I'm using log base 10 to get log(0.5) = -0.301

So for b = 0.5, we have,

[tex]\log_{0.5}(x) = \frac{\log(x)}{\log(0.5)} \approx \frac{\log(x)}{-0.301} \approx -3.322\log(x)[/tex]

The log(x) part on its own is always increasing. The negative coefficient out front flips it to always decreasing.

The function of g(x) is a transformation of the absolute values parent function which graphs shows g(x)

Answers

Answer:  Graph B

==============================================================

Explanation:

f(x) is shown in the blue dashed line, while g(x) is a solid black line.

When going from |x| to 3|x|, we are multiplying each y output value by 3. So a point like (4,4) on f(x) moves to (4,12) on g(x). A point like (-3,3) on f(x) moves to (-3,9) on g(x). And so on.

This will result in g(x) being taller and skinnier/narrower compared to f(x) as shown in graph B. We have vertical stretching going on here.

The vertex of each V shape is the same and that's at the origin (0,0).

No translations (horizontal or vertical shifting) are occurring.

The graph that shows the function g(x) = 3|x| is graph B.

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

Given that, a function of g(x) is a transformation of the absolute values, we need to find the parent function of g(x)

Function g(x) = 3|x| is a vertical stretch of 3 units of function f(x) = |x|, that is, they keep the same vertex at (0,0), just graph g is stretched, passing at (1,3) instead of (1,1) for example.

Hence graph B is correct.

Given circle and circle with radii of 6cm and 4cm respectively.




Compare the length of EF and GH.




The length of EF is ____the length of GH



The length of EF is___



The length of GH is ___

Answers

Solution :

Given that :

The radius of circle A = 6 cm

The radius of circle C = 4 cm

In circle A

[tex]\angle EAF = \theta = 140^\circ[/tex]

The length of arc EF = [tex]$2 \pi r \times \frac{\theta}{360^\circ}$[/tex]

                                   [tex]$=2 \times 3.14 \times 6 \times \frac{140^\circ}{360^\circ}$[/tex]

                                    = 14.653 cm

In circle C

[tex]\angle GCH = \theta = 140^\circ[/tex]

The length of arc GH = [tex]$2 \pi r \times \frac{\theta}{360^\circ}$[/tex]

                                   [tex]$=2 \times 3.14 \times 4 \times \frac{140^\circ}{360^\circ}$[/tex]

                                    = 9.769 cm    

Therefore,

The length of EF is 14.653 cm

The length of GH is 9.769 cm

The length of EF is  1.5 times the length of GH

i.e.                   14.653  = 1.5 x 9.769

                       14.653 = 14.653

Hence proved.

Is Social Darwinism a justifiable reason to colonize other areas of the world and exploit the people and resources of that region?

Answers

Answer:

Social Darwinism provided an ideological justification for the social inequalities that capitalism had brought with it: these would result from the hereditary inferiority of the poor and the hereditary excellence of the richer classes, which are best enjoyed under a laissez-faire system. Applied to peoples and races, it became a justification for racism and imperialism.

As can be seen, social Darwinism is a retrograde political and philosophical stance, which considered different ethnic or national groups as different in terms of capacity or development possibilities. Therefore, since this position has been regarded as false, social Darwinism has no justification in our time.

Answers

Answer:

The answer is below

Step-by-step explanation:

Trigonometric ratios shows the relationship between the sides of a right angled triangle and its angles. Some trigonometric ratios are:

sinθ = opposite / hypotenuse, cosθ = adjacent / hypotenuse; tanθ = opposite / adjacent.

In triangle PQR:

tanθ = QR / PQ

substituting gives:

3/4 = 9 / PQ

PQ = 9 * 4 / 3 = 12 cm

Applying Pythagoras in triangle PQR gives:

PR² = PQ² + QR²

PR² = 12² + 9²

PR² = 144 + 81 = 225

PR = 15 cm

Also in triangle PRS:

PS = (5/3)PR = (5/3)*15 = 25 cm

PS² = PR² + RS²

25² = 15² + RS²

625 = 225 + RS²

RS² = 400

RS = 20 cm

Which situation best represents a proportional relationship?

Answers

Answer:

Option (3)

Step-by-step explanation:

Two variables 'x' and 'y' show the proportional relationship if,

y ∝ x

y = kx

Here, k = Proportionality constant

Option (1)

If Sandra sold 2 bracelets for $3 and 3 bracelets for $6.

For y = 3 and x = 2,

3 = 2k

k = 1.5

For y = 6 and x = 3

6 = 3k

k = 2

Here, proportionality constant is different in both the cases.

Therefore, Option A doesn't show the proportional relationship.

Option (2)

Jeff ran 4 miles in 20 minutes and 6 miles in 24 minutes.

For y = 20 and x = 4,

20 = 4k

k = 5

For y = 24 and x = 6,

24 = 6k

k = 4

Here, proportionality constant is different in both the cases.

Therefore, there is no proportional relationship.

Option (3)

Lamont packed 27 glasses in 9 cases and 81 glasses in 27 cases.

For y = 27 and x = 9

27 = 9k

k = 3

For y = 81 and x = 27,

81 = 27k

k = 3

Here, proportionality constant is k = 3 for both the cases.

Therefore. Option (3) is the answer.

Option (4)

Fernanda placed 8 pencils in 2 boxes and 16 pencils in 8 boxes.

For y = 8 and x= 2.

8 = 2k

k = 4

For y = 16 and x = 8,

16 = 8k

k = 2

Here, proportionality constant is different in both the cases.

Therefore, Option (4) is not the answer.

help!! pls pls pls help!

Answers

Step-by-step explanation:

Going through this one by one, we can say:

For the first one ("Both functions are increasing on the interval (0, ∞)"), this does not need to be selected. Although h(x) increases as x increases, g(x) (the y value) decreases as the x value increases, or the graph moves to the right.

Next, we have "g(x) is increasing on the interval (-∞, 0)." The -∞ represents when x is at its lowest point, or the leftmost point possible for the curve. 0 represents the middle of the graph, cutting right through the y-axis. As g(x) is only increasing on negative values, this is true. It is important to note that the 0 has a parenthesis next to it, so the value 0 itself, where the graph is not increasing, is not included

After that, we have "The y-intercept of g(x) is greater than the y-intercept of h(x)." The y intercept is when x=0. For g(x), y=9 here, and for h(x), y=1. Thus, g(x) is greater, and this can be selected.

Furthermore, we have "The function h(x) represents a linear function." This means that for each value of x throughout the function, a change in x by 1 always results in the same change in y. When x goes from -1 to 0, h(x) increases by 0.75. When x goes from 0 to 1, h(x) increases by 3. Therefore, as 0.75 is not equal to 3, these are not the same.

Finally, the last statement is g(2) < h(2). As we can see on the graph, as x=2, the line is at g(x)  = 5. When x=2, h(x) is 16. As the value of h(x) (16) is greater than the value of g(x) (5) when x=2, this can be selected as well.
