The coordinates of the centroid of triangle DEF with the vertices (0,4) (6,6), and (2,2) is calculated as: (8/3, 4).

The formula for finding the coordinates of the centroid of a triangle is given as:

C(x, y) = [tex]( \frac{(x1+x2+x3)}{3}, ( \frac{(y1+y2+y3)}{3})[/tex].

Given the vertices of triangle DEF as follows:

D (0, 4) = [tex](x_1, y_1)[/tex]

E (6, 6) = [tex](x_2, y_2)[/tex]

F (2, 2) = [tex](x_3, y_3)[/tex]

Substitute the values into the centroid formula to find the coordinates:

C(x, y) = [(0 + 6 + 2)/3, (4 + 6 + 2)/3]

C(x, y) = (8/3, 12/3)

C(x, y) = (8/3, 4)

Therefore, the centroid has the coordinates that are calculated as: (8/3, 4).

Inequality that could be used to solve for x is;

1450 words + (265 words / day)x  = 3305 words

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given that Amy has already written 1450 words out of 3305 words.

And she writes at the rate of 265 words per day.

To establish the inequality which could be used to solve for x,

Then Firstly, we will form an equation for the total number of days required to write her paper,

1450 words + (265 words / day)x  = 3305 words.

Simplifying the above expression,

(265 words / day)x = 3305 words - 1450 words

To solve this linear equation, we'll find x = 7.

x = { 3305 words - 1450 words} / 265  words

x = 7 days.

Hence, inequality that could be used to solve for x is;

1450 words + (265 words / day)x  = 3305 words

The perimeter of the figure is 5.0.

What is a perimeter?

The perimeter of a two-dimensional shape is the distance around the outside of the shape. It is the sum of the lengths of all the sides of the shape. For example, the perimeter of a rectangle is the sum of the lengths of all four sides. The perimeter of a triangle is the sum of the lengths of all three sides.

To reflect a point across the line y=x, we can use the following formula:

(x', y') = (y, x)

Where (x', y') is the reflected point and (x, y) is the original point.

Using this formula, we can find the coordinates of the reflected points A' and B':

A' = (4, 4) -> (4, 4) -> (4, 4)

B' = (5, -1) -> (-1, 5) -> (-1, 5)

Therefore, the image of AB is A'B' with endpoints A'(4, 4) and B'(-1, 5).

To find the perimeter of the figure formed by the segments AB, B'B, and A'B', we can add up the lengths of these three segments. The length of AB can be found using the distance formula:

[tex]AB = \sqrt{((5-4)^2 + (-1-4)^2)}\\\\= \sqrt{(1^2 + (-5)^2)}\\\\= \sqrt{(1 + 25)}\\\\= \sqrt{26}[/tex]

The length of B'B can be found using the same formula:

[tex]B'B = \sqrt{((-1-(-1))^2 + (5-5)^2)}\\\\= \sqrt{(0^2 + 0^2)}\\\\= 0[/tex]

The length of A'B' can also be found using the distance formula:

[tex]A'B' = \sqrt{((-1-4)^2 + (5-4)^2)}\\\\= \sqrt{(-5)^2 + (1)^2}\\\\= \sqrt{25 + 1}\\\\= \sqrt{26}[/tex]

The perimeter of the figure is AB + B'B + A'B' = √26 + 0 + √26 = 2√26. To the nearest tenth, this is 5.0.

Hence, the perimeter of the figure is 5.0.

The value of the angle m ∠ DAB in the parallelogram is 128 degrees

In a given parallelogram, the opposite sides and angles are equal to one another.

In the question given;

m∠ ABC = 3x + 1

m∠ BCD = 8x - 8

m∠ DAB = ?

m ∠ ABC + m∠ BCD = 180°

The sum of the two angles is equal to 180 degrees

3x + 1 + 8x - 8 = 180

11x - 7 = 180

11x = 187

x = 17

However, m∠ DAB = m∠ BCD

Two opposite angles are equal

m∠ DAB = 8x - 8

m ∠ DAB = 8(17) - 8

m ∠ DAB = 128 degrees

WXYZ to JKLM

JM is equal to 9, ZW is 13.5, JK is 12, and WX is 18.

To obtain the coordinates of the other shape, multiply the original shape by the scale factor

What is the scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, we can increase the size of a rectangle with sides of 2 cm and 4 cm by multiplying each side by, let's say, 2.

13.5 / 9 = 1.5

9 * 1.5 = 13.5 \s12 * 1.5 = 18

You have a scale factor of 1.5. (because if u multiply 1.5 by the original shape, u get the new shape)

JKLM ~ WXYZ

So  JK ~  WX

So the scale factor  =  WX / JK

Scale Factor   =  18 / 12 =   3 / 2    =   1.5

A plot is a graphical technique for representing a data set, typically in the form of a graph that depicts the relationship between two or more variables. The plot can be created either by hand or by computer. Previously, mechanical or electronic plotters were used.

Graphs are a visual representation of the relationship between variables that are very useful for humans because they allow them to quickly derive an understanding that would not have been possible from lists of values. Graphs can also be used to read off the value of an unknown variable plotted as a function of a known variable given a scale or ruler, but this can also be done with data presented in tabular form.

Hello,

The slope-intercept form of a linear equation is:

y = mx + b

where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.

To write the equation of the line with slope m = -1 that passes through the point (4, 5), you can use the point-slope form of a linear equation, which is:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line and m is the slope of the line. Plugging in the values, we get:

y - 5 = -1(x - 4)

This simplifies to:

y - 5 = -x + 4

Finally, we can rearrange the terms to put the equation in slope-intercept form:

y = -x + 9

This is the equation of the line with slope m = -1 that passes through the point (4, 5).

One hose can fill a small swimming pool in 75 minutes. Two hoses will fill the pool in 30 minutes when working together.

Given, the volume ( the space occupied by an solid object)  per minute

Smaller hose fills  the pool in 75 minutes. (1/75)

A larger one can fill the pool in 50 minutes. (1/50)

So, together they will fill = (1/ 75 ) + (1/50) , the lcm of 75 and 50 is 150

                                            =  (2/150) + (3/150)

The first differences of the given terms are ...

  18 -12 = 6

  27 -18 = 9

These are not constant, so the sequence is not an arithmetic sequence.

The ratios of sequential terms are ...

  18/12 = 1.5

  27/8 = 1.5

These are constant, suggesting the sequence is an exponential sequence. The equation for the n-th term is ...

  an = 12(1.5^(n-1))

Then the 8th term is ...

  a8 = 12(1.5^7) = 205.03125

The formula for calculating percentage is (value/total value)100%.When a piece of a whole is stated as a percentage, it is not a fraction but rather a number between 0 and 100. There are three percentages: 100% for everything, 50% for half of it, and 0% for the remaining portion.

25% of new students come from one-parent households, which equals 0.25;

75% of new students come from two-parent households, which is 0.75.

42% of incoming students from homes with only one parent go on to complete their college studies = 0. 42
