Where are the vertices of triangle A’B’C’ located? Show your work or explain your steps. (4points)

Answers

The vertices of ∆A′B′C′ are A′(-6, 5), B′(-6, 8), and C′(-10, 5) upon the application of the translation rule.

What is the translation rule in geometry?

In geometry, a translation is a transformation that moves every point of a figure the same distance in the same direction. In the case of a triangle, a translation rule describes how to move each vertex of the triangle to a new location to create a new triangle with the same size and shape, but in a different position.

A translation rule for a triangle is given by a pair of numbers (a, b), which indicate the amount of horizontal and vertical movement of the vertices. Specifically, the rule is given by the formula:

(x, y) → (x + a, y + b)

This formula means that we move every point in the triangle a unit to the right or left (depending on the sign of a) and b units up or down (depending on the sign of b).

The translation rule (x, y) → (x − 3, y + 4) means that we move every point in the original triangle left by 3 units and up by 4 units. So, the translation is described as a leftward shift of 3 units and an upward shift of 4 units.

To find the vertices of ∆A′B′C′, we apply the translation rule to each vertex of ∆ABC:

Vertex A: (x, y) → (x - 3, y + 4)

(-3, 1) → (-3 - 3, 1 + 4) = (-6, 5)

So, vertex A of ∆A′B′C′ is located at (-6, 5).

Vertex B: (x, y) → (x - 3, y + 4)

(-3, 4) → (-3 - 3, 4 + 4) = (-6, 8)

So, vertex B of ∆A′B′C′ is located at (-6, 8).

Vertex C: (x, y) → (x - 3, y + 4)

(-7, 1) → (-7 - 3, 1 + 4) = (-10, 5)

So, vertex C of ∆A′B′C′ is located at (-10, 5).

angle LIJ = 129 degrees

How to find the missing angles

The missing angles are solved using the inscribed angle theorem and the knowledge of cyclic quadrilateral

arc KLI = 138 degrees = 2 * angle KJI (inscribed angle theorem)

angle KJI = 138 / 2

angle KJI = 69 degrees

angle KLI + angle KJI = 180 degrees (cyclic quadrilateral property)

where angle KJI = 69

angle KLI = 180 - 69

angle KLI = 111 degrees

Answers

The problem can be translated into an equation as follows: 8x = (1/3)(x+2)

the answer that represents this situation is: 8x = (1/3)(x+2)

Simplifying the right side of the equation:

8x = (1/3)x + (2/3)

Multiplying both sides of the equation by 3 to eliminate the fraction:

24x = x + 2

Subtracting x from both sides of the equation:

23x = 2

According to the National Student Clearinghouse Research Center, women now comprise 60% of enrollment in universities. What is the probability in a random sample of 55 university students that more than 35 are women? Round your answer to 3 decimal places.

Answers

The probability that more than 35 students are women in a random sample of 55 university students is 0.256.

What is binomial distribution?

The binomial distribution is a probability distribution that expresses the number of successes in a finite number of independent trials when the chance of success is constant and there are only two potential results (success or failure). Since a known chance of success for each trial is known, we may use it to determine the likelihood of a certain number of successes (or failures) in a set number of trials.

Given that p = 60% = 0.6, n = 55.

Using normal approximation we have:

SD = sqrt(np(1-p))

= sqrt(55 x 0.60 x 0.40) = 3.05

The z-score is:

z = (X - np) / SD)

z = (35 - (0.4)(0.6)) / 3.05

z = 11.39 = 0.256.

Hence, the probability that more than 35 students are women in a random sample of 55 university students is 0.256.

. From a rectangular metal sheet of size 20 cm by 30 cm, a circular sheet as big as possible is cut. Find the area of the remaining sheet.​

Answers

The largest possible circle that can be cut from a rectangular sheet is a circle whose diameter is equal to the length of the shorter side of the rectangle (20 cm in this case). So, the radius of the circle is 10 cm.

The area of the circle is given by the formula A = πr², where r is the radius. Substituting r = 10 cm, we get:

A = π(10 cm)²
A = 100π cm²

The area of the remaining sheet is equal to the area of the rectangle minus the area of the circle. The area of the rectangle is 20 cm × 30 cm = 600 cm². So, the area of the remaining sheet is:

600 cm² - 100π cm² ≈ 196.3 cm²

Therefore, the area of the remaining sheet is approximately 196.3 square centimeters.

Find the extract value of x

Answers

Answer:

25 + 5√29

Step-by-step explanation:

(I added a photo below)

First, let's find BC using the Pythagorean theorem (from ∆BCD):

[tex] {bc}^{2} = {25}^{2} + {10}^{2} = 625 + 100 = 725[/tex]

[tex]725 > 0[/tex]

[tex]bc = \sqrt{725} =5 \sqrt{29} [/tex]

Then we see, that AB = 25 + x

So, now we can find AC:

[tex] {ac}^{2} = ({25 - x})^{2} - ({5 \sqrt{29} })^{2} = 625 - 50x + {x}^{2} - 25 \times 29 = 625 - 50x + {x}^{2} - 725 [/tex]

Now we have a quadratic equation:

[tex] {x}^{2} - 50x - 100 = 0[/tex]

[tex]d = {b}^{2} - 4 \times a \times c = ({ - 50})^{2} - 4 \times 1 \times ( - 100) = 2500 + 400 = 2900 > 0[/tex]

[tex]x1 = \frac{ - b - \sqrt{d} }{2a} = \frac{50 - 10 \sqrt{29} }{2} = 25 - 5 \sqrt{29} [/tex]

This is a negative number and we cannot use it, since x has to be a natural number

[tex]x2 = \frac{ - b + \sqrt{d} }{2 a} = \frac{50 + 5 \sqrt{29} }{2} = 25 + 5 \sqrt{29} [/tex]

Answers

Option B. The length of the hypotenuse of Carter's triangle is 13cm.

Since Carter's triangle is similar to Peyton's triangle, the ratio of corresponding side lengths will be the same. Let's use x to represent the length of the hypotenuse of Carter's triangle.

We know that the ratio of the lengths of the hypotenuse and the shorter leg of Peyton's triangle is 13:5. So, the ratio of the lengths of the hypotenuse and the shorter leg of Carter's triangle must also be 13:5.

Thus, we have x/5 = 13/5, which simplifies to x = 13.

In the exponential decay, A) r = -0.0839 , B) r = -8.39% , C) Value=$11,800.

What is exponential decay?

The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.

To find the annual rate of change between 1992 and 2006, we can use the formula:

r = [tex](V_2/V_1)^{1/n}-1[/tex]

where V1 is the initial value, V2 is the final value, and n is the number of years between the two values.

=>r = -0.0839

Therefore, the rate of change between 1992 and 2006 is -0.0839.

To express the rate of change in percentage form, we can multiply the result from part A by 100:

=>r = -0.0839 x 100

=> r = -8.39%

Therefore, the rate of change between 1992 and 2006 is a decrease of 8.39%.

To find the value of the car in the year 2009, we can assume that the value continues to drop at the same percentage rate as calculated in part A.

From 2006 to 2009, there are 3 years. So, using the formula for exponential decay, we have:

where V0 is the value in 2006, r is the rate of decrease, and n is the number of years between 2006 and 2009.

=>V = 11792.51

Therefore, the value of the car in the year 2009 would be approximately $11,800 (rounded to the nearest $50).

We have provide that Small Monster collector is visiting the Knightrola region, bringing 30 Small Monster Containment Devices with them. We have to determine the different types of Small Monsters can the collector capture under the following conditions :

a) Here n = 30,

Number of monstor access by him = 7 {Grass, Space Electric Scooter, Mask, Citrus, and Rubber Duck}

So, different types of Small Monsters can the collector capture = ³⁰C₇₋₁ = ³⁰C₆

b) Here, he captures at least one of each of those 7 places. So, we have to distribute 23 ( 30 -7) among 7 places

= ²³C₆ = 100947

c) Here provided that atleast one to all plus atleast five Space types captured, so we have to distribute 30 - 11 = 19 devices among 7 places, = ¹⁹C₆ = 27132

d) All above conditions plus at most four Electric Scooter types captured, so ³⁰⁻¹¹C₅ + ³⁰⁻¹²C₅+ ³⁰⁻¹³C₅ + ³⁰⁻¹⁴ C₅

Answers

The z-intercept is at 500, the domain of the function is all non-negative real numbers, or [0, ∞) and the maximum revenue is 500

What does the z-intercepts interpret in this situation?

1. The graph of the function is attached below;

2. The z-intercept is where the graph intersects the x-axis, which occurs when the revenue is 0. In this situation, the z-intercept represents the maximum price that the company can charge for the cell phone and still expect to sell some units. So, the z-intercept is $500, meaning if the company charges more than $500, it will not sell any cell phones and its revenue will be 0.

3. No, 0≤x≤ 600 is not an appropriate domain for the function. The company can charge any price, not just prices between 0 and 600 dollars. The domain of the function should be all non-negative real numbers, or [0, ∞).

4. The maximum revenue occurs at the point where the slope of the function changes from negative to positive, which is the vertex of the parabola. In this case, the function r(x) is a linear function, so there is no vertex. The maximum revenue occurs at the endpoint of the domain, which is x=500, since the company cannot charge more than $500 without reducing the number of phones sold to 0. Therefore, the company should charge $500 to get the maximum revenue.

Determine the length of side AB and BC in triangle ABC.
AB=9.68,BC=7.04
AB=8.8,BC=6.4
AB=9.152,BC=6.656
AB=7.92,BC=5.76

Answers

In triangle ABC, the values of AB and BC are 9.68 and 7.04 respectively i.e. A.

What is a triangle's definition?

A triangle is a geometric form that has three straight sides and three angles. It is a fundamental geometric form that is frequently utilised in mathematics, science, and everyday life.

Triangles are distinguished by three sides and three angles. The sum of each triangle's three angles is always 180 degrees. Triangles are classified according to the length of their sides and the measurement of their angles.

Now,

As given ΔDEF ≈ΔABC

that means ratio of all sides will be equal

i.e. AB/DE=BC/EF=AC/DF

then AB/8.8=6.71/6.1

AB=1.1*8.8

AB=9.68

and BC/6.4=6.71/6.1

BC=1.1*6.4

BC=7.04

Hence,

            the values of AB and BC are 9.68 and 7.04 respectively.

Draw the image of traingel ABC under a dilation whose center is p and scale factor is 1/2

Answers

A graph of the image of ABC under a dilation whose center is P and scale factor is 1/2 is shown in the image below.

What is dilation?

In Geometry, a dilation can be defined as a type of transformation which typically changes the size of a geometric shape, but not its shape.

In this exercise, we would use an online graphing calculator to plot the image of ABC after a dilation by a scale factor of 1/2 centered at P.

Based on the image (see attachment), we can logically deduce that each vertex is 1/2 times as far from center P as the original vertex and each segment is 1/2 times as long as the original:

Side length A'C' = 8.2/2 = 4.1

Side length A'B' = 5.7/2 = 2.85

Side length B'C' = 12.2/3 = 6.1

The initial population of a bacterial culture is 2000, growing at a fixed rate. Table shows the population every hour for six hours.

A. Find the equation that models this relation. (round to one decimal place).

B. Use the equation to find the population of bacteria after 12 hours after 24 hours.

Answers

Answer: A. To find the equation that models this relation, we can plot the data and look for a trend.

From the graph, we can see that the data follows an exponential growth pattern. The equation for exponential growth is:

y = ab^x

where y is the final population, a is the initial population, b is the growth rate, and x is the time in hours.

Using the data from the table, we can find the value of b:

b = y/x

where y is the population after x hours.

For example, after 2 hours, the population is 5000:

b = 5000/2 = 2500

We can repeat this process for each time period and find the average value of b:

b = (2500 + 3125 + 3906.25 + 4882.81 + 6103.51 + 7629.38) / 6 = 4275.5

Now that we have the value of b, we can find the equation that models the relation:

y = 2000(4275.5)^x

Rounding to one decimal place:

y = 2000(4.3)^x

B. Using the equation, we can find the population after 12 and 24 hours:

y = 2000(4.3)^12 ≈ 8,898,335.7

y = 2000(4.3)^24 ≈ 7.42 x 10^13
