It is not possible to construct a triangle with 6cm, 9cm, and 17cm.

The sides measure 6 cm, 9 cm, and 17 cm in length.

Only when the third side is greater than the sum of any two sides can a triangle be drawn. This the condition.

Let's verify the rule now.

6 + 9 > 17        Not true

6 + 17 > 9        True

9 + 17 > 6        True

As 6 + 9 > 17 does not satisfy the condition.

Hence, it is not possible to construct a triangle having 6cm, 9cm, and 17cm in length.

The midsegment linking the cartesian coordinates of two of a triangle's sides is parallel to the fourth aspect of the triangle, and its length is half that of the third side, according to the midsegment theorem.

The assertions that the Greek mathematician Pythagoras discovered the properties of right-angled triangles in the fifth century BC just did not match up, according to many. Some people think following commentary shows it was a joint effort among his disciples, the Pythagoreans.

Equilateral: equal angles and all three sides. Acute isosceles: two identical sides and angles, both of which are only about 90 degrees. Acute scalene has irregular sides and angles, all of which are under 90 degrees. Obtuse isosceles: two identical sides and angles, one of which is more than 90 degrees.

For the figure shown in the image having TV as the midsegment, the length of TV is 40

When the comparable triangles' angles are congruent and their respective sides are proportionate, this is referred to as similar triangles in geometry.

In light of this, if the triangle's corresponding angles are congruent, then the side should be proportionate.

For the given figure, the proportionate sides are

UV and TV, UW and WX

Calculating for s

UV / TV = UW / WX

1 / (-2s + 42) = 2 / (3s + 77)

cross multiplying

3s + 77= 2(-2s + 42)

3s + 77= -4s + 84

collecting like terms

3s + 4s = 84 - 77

7s = 7

s = 1

solving for TV

= -2s + 42

= -2 * 1 + 42

= 40

The turning point of the function is x = 1 and it is a local minima.

The curve of a function has peaks and troughs called maxima and minima. A function may have any number of peaks and minima. Calculus allows us to determine any function's maximum and lowest values without ever consulting the function's graph. Maxima will be the curve's highest point within the specified range, while minima will be its lowest.

Extrema is the result of maxima and minima combined. The graph in the graphic below shows several peaks and falls. We obtain the function's maximum and lowest values at x = a and 0 respectively, and at x = b and c respectively. The valleys are the minima and all the peaks are the maximum.

In a function, maxima and minima can be of two different types:

Local Maxima and Minima

Global or Absolute Maxima and Minima

The function is

y = [tex](x-1)^{2}[/tex] for -3 ≤ x ≤ 3

differentiating both side with respect to x we get

[tex]\frac{dy}{dx} = 2(x-1)[/tex]

for maxima and minima [tex]\frac{dy}{dx} = 0[/tex]

or, 2(x-1) = 0

or x = 1

The actual perimeter is 2934. The perimeter of a rectangle is calculated as P = length + breadth + length + breadth. Alternatively, P = 2(length + breadth).

Perimeter=2(l + b)

=2[6.3cm +10cm) = 2x16.3 cm 32.6cm

Scale 1 cm = Actual 90m.

32.6cm 32.6x90m

= 2934 m

We sum the lengths of all four sides to determine the perimeter of a rectangle. Because opposing sides of a rectangle are always equal, we must obtain the length and breadth measurements to calculate the perimeter of a rectangle. The perimeter of a rectangle is equal to double the sum of its length and breadth.

To calculate the perimeter, or distance around the rectangle, sum all four side lengths. This may be done quickly by adding the length and breadth and then multiplying the total by two because each side length has two lengths. The perimeter formula is perimeter = (length + width)2.

When three line segments intersect at three different angles, the result is a figure known as an Angle Sum Triangle. Triangles always contain a total of 180 degrees of angles.

Any triangle's angles add up to 180 degrees, according to the Angle Sum Triangle Theorem. By applying fundamental geometry concepts, this theorem can be demonstrated. Obtuse, right, or acute angles can all be found in triangles.

Triangle-related issues can be resolved using the Angle Sum Triangle theorem, a crucial geometry theorem. It can be used to gauge a triangle's angle sizes or to establish whether it is acute, right, or obtuse.

A)

∠ABC =∠BCA

∠BAC + ∠ABC + ∠BCA = 180

55 + 2∠ABC =

2∠ABC = 180 - 55

2∠ABC = 125

∠ABC =∠BCA = 75.5

100 + 2∠ECD =  180

∠ECD = 40

∠ACE = 180 - 75.5+40

∠ACE = 64.5°

B) ∠PRQ = 90°  any triangles one side crosses through centre then the opposite angle is 90°.

C) ∠AOC = 40° when inside a circle, the angle on centre is double the angle touching the circumference

D) ∠a = 360 - 90 + (180-60) + (180-80)

∠a = 50°

2. The value of angle be can be calculated using angle sum property of triangle i.e.

(x+5) + 3x + x = 180

5x + 5 = 180

5x = 175

x = 175/5

x = 35

∠B = 3(35)

∠B = 105°

Thus, the unknown values are ∠ACE = 64.5°, ∠PRQ = 90°, ∠AOC = 40° and  ∠a = 50° along with question no. 2, ∠B = 105°.

Para calcular el 18% menos de un número, se puede utilizar la fórmula: número original x (1 - porcentaje en decimal). En este caso, para calcular el 18% menos de 41, se puede utilizar la fórmula: 41 x (1 - 0.18) = 41 x 0.82 = 33.62. Entonces, el 18% menos de 41 es 33.62.

Espero que esto ayude :)

Answer:

El número es:

50

Step-by-step explanation:

Porcentaje significa "por cada cien"

18% = 18/100 = 0.18

El número buscado corresponde al 100%

Si es el 18% menos quiere decir que corresponde a:

100 - 18 = 82%

Entonces:

Por regla de tres:

41 es a 82%

A es a 100%

A = 41 * 100 / 82

A = 4100 / 82

A = 50

50 - (50*0.18) = 50 - 9 = 41

The mean of these scores is 16.

The mean is a measure of central tendency that indicates the average value of a set of data. It is calculated by adding up all of the individual values in a dataset and dividing that sum by the number of values in the dataset. In mathematical terms, the mean is represented by the symbol "µ" (mu) and is calculated as:

µ = (sum of all observations) / (number of observations)

To find the mean of these scores, you would add up all of the individual scores and divide by the total number of scores.

First, we find the total score of the 5 students who scored 10: 5 students * 10 points/student = 50 points

Then, we find the total score of the 10 students who scored 15: 10 students * 15 points/student = 150 points

Then, we find the total score of the 10 students who scored 20: 10 students * 20 points/student = 200 points

Now we add all the total scores of students: 50+150+200 = 400 points

Finally, to find the mean score, we divide the total score by the number of students: 400 points / 25 students = 16 points/student.

Therefore, the mean of these scores is 16.

1/90

The probability of selecting a three-digit number with the property that one digit is equal to the product of the other two is 1/90. This is because there are only 9 possible digits (1, 2, 3, 4, 5, 6, 7, 8, 9) to choose from, and each of these digits can be multiplied by itself twice to give 9 possible combinations. Therefore, there are 9 three-digit numbers that satisfy the given condition, and these 9 numbers can be chosen from a total of 900 three-digit numbers (10 x 10 x 10 = 1000, minus the 100 numbers beginning with 0). Thus, the probability of selecting a three-digit number with the property that one digit is equal to the product of the other two is 9/900, which can be simplified to 1/90.

Step-by-step explanation:

What is a triangle?

A triangle is a polygon with 3 sides.

Given that, the measures of the two angles of a triangle are 50° and 85°.

Let the measure of the third angle be x.

Since the sum of the interior of a triangle is 180°, it follows,

50°+85°+x=180°

135° +x = 180°

x = 180° - 135°

x = 45°

Hence, the measure of the third angle of the triangle is 45°.

Empirical probability is a sort of experimental probability that is based on historical data. Empirical probability is, then, an illustration of  the likelihood of an occurrence occurring based on prior data.

The formula of the empirical probability is:

Experimental probability  = number of times an event occurs / total number of outcomes.

In the problem, total number of classes = 50

From the graph, we can read that:

- number of classes with 6 left-handed students = 2

- number of classes with 7 left-handed students = 1

Answer: Parallel

Step-by-step explanation:

To solve this question, we need to find the slopes of both lines q and r.

First, let's find the slope of line q.

Δx/Δy=-7/-6 = 7/6

Next, the slope of line r.

Δx/Δy=-7/-6 = 7/6

Both lines have the same slope.

Therefore, they are parallel.

Answer:

Q = 216 - 0.5P

Step-by-step explanation:

One approach to modeling the demand as a function of the cost is to use a linear demand equation of the form:

Q = a - bP

where Q is the quantity demanded, P is the price, and a and b are constants. To find these constants, we can use the two points given:

When P = $180, Q = 8 portraits, so 8 = a - b * 180

When P = $100, Q = 24 portraits, so 24 = a - b * 100

Solving the system of equations gives us:

a = 216

b = 0.5

So, the demand equation is:

Q = 216 - 0.5P

This represents the demand for portraits as a function of the price, where the demand decreases linearly as the price increases.
