Answer:  x = 32°

Step-by-step explanation:

(3x - 4) + (3x - 8) = 180

3x - 4 + 3x - 8 = 180

6x - 12 = 180

6x - 12 + 12 = 180 + 12

6x = 192

6x ÷ 6 = 192 ÷6

x = 32

Answer:

Left angle = 60°

Top angle = 120°

Right angle = 60°

Step-by-step explanation:

Use what you know about angle relationships to set up equations you can solve for each variable.

The top top angle, for example, added to one of the other angles must equal 180° because they are supplementary.

You have two variables, so you need at least two equations (I made three but only used two).

There must exist a vertex u in T such that the distance between u and v is at most (n-1)/2.

To prove the existence of a vertex u in tree T such that the distance between u and v is at most (n-1)/2, we can employ a contradiction argument. Assume that such a vertex u does not exist.

Since the number of vertices in T is odd, there must be at least one path from v to another vertex w such that the distance between v and w is greater than (n-1)/2.

Denote this path as P. Let x be the vertex on path P that is closest to v.

By assumption, the distance from x to v is greater than (n-1)/2. However, the remaining vertices on path P, excluding x, must have distances at least (n+1)/2 from v.

Therefore, the total number of vertices in T would be at least n + (n+1)/2 > n, which is a contradiction.

Hence, there must exist a vertex u in T such that the distance between u and v is at most (n-1)/2.

The expected rate of return for a poor investment is the expected return minus the expected loss.  the expected return on the investment would be $20.

Step 1: Determine the investment amount. Let's assume the investment amount is $1,000.Step 2: Calculate the expected rate of return. To calculate the expected rate of return, you need to take the estimated return on the investment and subtract the amount of risk associated with the investment. For example, if the investment has a 5% expected return and a 3% risk, the expected rate of return would be 2%. Therefore, the expected rate of return for a poor investment of $1,000 would be 2%.Step 3: Multiply the expected rate of return by the investment amount. To calculate the expected return on the investment, multiply the expected rate of return (2%) by the investment amount ($1,000). Therefore, the expected return on the investment would be $20.

The statement that is equivalent to |6x-3|=3 is: 6x-3=3 or 6x-3=-3

For the equation to be true, two scenarios need to be considered:

When the expression 6x-3 is positive and equals 3:

6x-3 = 3

When the expression 6x-3 is negative and equals -3:

6x-3 = -3

By solving these two equations, we can find the equivalent statement:

Solving 6x-3 = 3:

Adding 3 to both sides gives us:

6x = 6

Dividing both sides by 6:

x = 1

Solving 6x-3 = -3:

Adding 3 to both sides gives us:

6x = 0

Dividing both sides by 6:

x = 0

Therefore, the equivalent statement to |6x-3|=3 is:

6x-3=3 or 6x-3=-3, which can be further simplified to:

6x-3=3 or 6x-3=-3

In the quadrilateral ACDE, we can identify two congruent angles: angle CDA and angle C'EA.

In the given diagram, we have ACDE as a quadrilateral, and we know that CD is congruent to CE. To identify two congruent angles, let's examine the properties of the quadrilateral.

Since ACDE is not specified to be a particular type of quadrilateral (such as a parallelogram or rectangle), we cannot directly infer congruent angles from its properties.

However, we can make use of some general properties of quadrilaterals to identify two congruent angles. One property is that the sum of the interior angles of a quadrilateral is always 360 degrees.

Let's consider angle C as one of the angles in ACDE. Since CD is congruent to CE, we can denote angle CDE as angle C' to represent the congruent angles.

Now, using the property that the sum of the interior angles of a quadrilateral is 360 degrees, we can express the relationship between the angles of ACDE as:

∠ACD + ∠CDE + ∠DEA + ∠EAC = 360 degrees

Since CD is congruent to CE, angles CDA and CEA are also congruent (opposite angles in a quadrilateral). So, we can rewrite the equation as:

∠ACD + ∠CDA + ∠C'EA + ∠EAC = 360 degrees

Since we want to identify two congruent angles, let's focus on angles CDA and C'EA. These two angles are formed by the intersection of the congruent sides CD and CE with different adjacent sides.

Therefore, we can conclude that angles CDA and C'EA are congruent in ACDE.

In summary, in the quadrilateral ACDE, we can identify two congruent angles: angle CDA and angle C'EA.

b) The value returned is -0.896.

We have,

The circle's radius is 3 units long and the terminal point is located at (−2.69,−1.33)

a. Since the circle's radius is 3 units long, we divide the x-coordinate by 3:

x-coordinate of terminal point: -2.69

Number of radius lengths to the right: -2.69 / 3 ≈ -0.896

However, since the angle is measured from the 3-o'clock direction, we consider it to be in the clockwise direction.

Thus, the number of radius lengths to the right is

Number of radius lengths to the right: -(-0.896) = 0.896

Therefore, the terminal point is 0.896 radius length.

b. Using Trigonometry

cos(h) = x-coordinate of terminal point / radius length

Answer:

Step-by-step explanation:

The five number summary will be the mean, median, interquartile range, minimum value and the maximum value.

Mean is the average of the data. It is the sum total of the numbers divided by the total number.

Mean = 64+72+73+60+65+86+72+69+74/9

Mean = 635/9

Mean = 70.6inches

Median is the middle value after rearrangement. Re-arrangement can be either in ascending or descending order of magnitude​.

On re-aaranging

60, 64, 65, 69), 72, (72, 73, 74, 86

It can be seen that the number at the middle is 72, hence the median data is 72inches

Maximum value is the highest number in the data given. The highest number is 86 according to the data.

Minimum value is the lowest number in the data given. The lowest number is 60 according to the data.

Interquartile range is the difference between the upper quartile sand the lower quartile. Quartiles divides the data into four equal parts

IQR = Q3-Q1

Q3 is the upper quartile

Q1 is the lower quartile

Q1 is the median of the upper part of the dataset i.e 86, 72, 69, 74​

Q1 = 72+69/2

Q1 = 70.5

Q1 is the median of the lower part of the dataset i.e 64, 72, 73, 60

Q3 = 72+73/2

Q3 = 72.5

IQR = 72.5-70.5

IQR = 2.0

Hence the five numbers are 70.6, 72, 86, 60 and 2.0

Answer:

D

Step-by-step explanation:

the sequence has a common difference between consecutive terms, that is

- 19 - (- 16) = - 19 + 16 = - 3

- 22 - (- 19) = - 22 + 19 = - 3

- 25 - (- 22) = - 25 + 22 = - 3

this indicates the sequence is arithmetic with explicit formula

\(a_{n}\) = a₁ + (n - 1)d

here a₁ = - 16 and d = - 3 , then

\(a_{n}\) = - 16 + (n - 1)(- 3)

Answer:

D. aₙ = (-16) + (n - 1)(-3)

Step-by-step explanation:

An explicit formula for a sequence allows you to find the nth term of the sequence.

The given sequence is arithmetic as it has a common difference of -3 between terms. Each term is 3 less than the previous term:

\(a_1=-16\)

\(a_2=a_1-3=-16 - 3 = -19\)

\(a_3=a_2-3=-19 - 3 = -22\)

\(a_4=a_3-3=-22 - 3 = -25\)

The general formula to find the nth term (aₙ) of an arithmetic sequence is:

\(\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}\)

Substitute a = -16 and d = -3 into the formula:

\(a_n=(-16)+(n-1)(-3)\)

Therefore, the matching answer option is option D.

The length of one side of the equilateral triangle in terms of x is 6x.

To find the length of one side of the equilateral triangle in terms of x, we need to consider the perimeter of both the rectangle and the equilateral triangle.

The perimeter of a rectangle is given by the formula:

Perimeter of rectangle = 2(length + width)

In this case, the length of the rectangle is 7x cm, and the width is 2x cm. Substituting these values into the formula, we have:

Perimeter of rectangle = 2(7x + 2x) = 2(9x) = 18x

We are told that the equilateral triangle has the same perimeter as the rectangle.

Since an equilateral triangle has all sides equal, the perimeter can be calculated by multiplying the length of one side by 3.

Therefore, we have:

Perimeter of equilateral triangle = 3(side length)

Since the perimeter of the equilateral triangle is equal to the perimeter of the rectangle (18x), we can set up the equation:

3(side length) = 18x

Dividing both sides of the equation by 3, we get:

side length = 6x

Hence, the length of one side of the equilateral triangle in terms of x is 6x.

The solution to the inequalities, y < 6 and y > x + 3 is the common intersecting region.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, y < 6.

Now, To determine wether it inclues the origin or not we'll set, y = 0.

So, 0 < 6 is true so y < 6 includes the origin.

Now, y > x + 3.

0 > 0 + 4 is not true therefore, y > x + 3 doest not inclue the origin.
