Identify and write the range of possible values for x

Identify And Write The Range Of Possible Values For X

Answers

Answer 1

The range of possible values for x is approximately -14.7 to 14.7. However, since x represents a length, it cannot be negative. Thus, the range of possible values for x is approximately 0 to 14.7.

What is range?

The range refers to the difference between the maximum and minimum values in a dataset.
The range is easy to calculate and provides a quick estimate of how much variation there is in the dataset.

We have:

∠ABC + ∠ABD + ∠BDA + ∠BAC = 360°

120° + 115° + ∠BDA + ∠BAC = 360° (substituting given values)

∠BDA + ∠BAC = 125°

Now, we can use the law of cosines to relate the sides and angles in each triangle:

AC² = AB² + BC² - 2ABBCcos(∠ABC)

(4x-10)² = AB² + 24² - 2AB24cos(120°)

(4x-10)² = AB² + 576 + 24AB

AD² = AB² + BD² - 2ABBDcos(∠ABD)

40² = AB² + 24² - 2AB24cos(115°)

AB² - 48AB + 496 = 0

Using the quadratic formula to solve for AB, we get:

AB = (48 ± √(48² - 4×496))/2

AB = 24 ± 2√211

Since AB = 24 + 2x, we have:

24 + 2x = 24 + 2√211 or 24 - 2√211

By Solving for x in each case, we get:

x = √211 + 0.5 ≈ 14.7 or x = -√211 + 0.5 ≈ -14.7

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

A real estate broker decides to lease a car for 36 months. Suppose the anual interest rate is 7.8%, the negotiated price is $49,000, there is no trade-in, and the down payment is $4,000. Find the monthly lease payment (in dollars). Assume that the residual value is 49% of the MSRP of $51,500. (Round your answer to the nearest cent.)

Answers

Answer:

To find the monthly lease payment, we need to use the formula:

Monthly lease payment = (Net capitalized cost - Residual value) / Lease term in months

where:

Net capitalized cost = negotiated price - down payment

Residual value = percentage of MSRP x MSRP

Lease term in months = 36

First, we need to calculate the net capitalized cost:

Net capitalized cost = $49,000 - $4,000 = $45,000

Next, we need to calculate the residual value:

Residual value = 49% x $51,500 = $25,235

Now we can plug in the values and solve for the monthly lease payment:

Monthly lease payment = ($45,000 - $25,235) / 36 = $548.76

Therefore, the monthly lease payment is approximately $548.76.

4. Myron Security, Inc., had total sales for 1 year of $945,860. Their advertising expenses were $57,370. a. Estimate the percent advertising expenses were of total sales.​

Answers

The calculated value of the percent advertising expenses were of total sales is 6.07%

How to estimate the percent advertising expenses were of total sales.​

To estimate the percent advertising expenses were of total sales, we need to calculate the ratio of advertising expenses to total sales and then convert it to a percentage.

The ratio of advertising expenses to total sales is:

$57,370 / $945,860 = 0.0607

To convert this ratio to a percentage, we can multiply it by 100:

0.0607 x 100 = 6.07%

Therefore, we can estimate that the advertising expenses were approximately 6.07% of the total sales.

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

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).

. 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.

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.

The coefficient of variation (CV) is a measure of relative variability, which expresses the standard deviation as a percentage of the mean. It can be calculated as follows:

[tex] \sf \: CV = \frac{standard \: deviation}{mean} \times 100%[/tex]

In this case, the mean number of citations is 23.2, and the standard deviation is 3.1. Thus, the coefficient of variation is:

[tex] \sf \: CV = \frac{3.1}{23.2} \times 100% [/tex]

What is right angled triangle?

A right angled triangle, also known as a right triangle, is a type of triangle that has one angle that measures exactly 90 degrees, called the right angle. This angle is formed where the two shorter sides of the triangle meet.

To solve this problem, we can use the concept of special right triangles, specifically the 3-4-5 right triangle. In a 3-4-5 right triangle, the sides are in the ratio of 3:4:5.

Let's label the length of the triangle as [tex]$L$[/tex], the height as [tex]$H$[/tex], and the hypotenuse as [tex]X[/tex].

The Pythagorean theorem states that in a right triangle, the sum of the squares of the legs is equal to the square of the hypotenuse. Therefore, we can set up the following equation:

[tex]$$ L^2 + H^2 = X^2 $$[/tex]

Substitute the given values.

We are given that [tex]$L = 27$[/tex] and [tex]$H = 36$[/tex], so we can substitute these values into the equation:

[tex]$$ 27^2 + 36^2 = X^2 $$[/tex]

Simplify the equation.

Evaluating the squares on the left side, we get:

[tex]$$ 729 + 1296 = X^2 $$[/tex]

Simplifying the right side, we get:

[tex]$$ 2025 = X^2 $$[/tex]

Solve for X.

Taking the square root of both sides, we get:

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).

Using congruent angles , we have been able to prove that the sum of the interior angles of ΔABC is 180°.

How to find the angle proof?

We are given that:

A, B, and C form a triangle.

The sum of the interior angles of ΔABC is 180°.

We want to find the complete the statements to prove that the sum of the interior angles of ΔABC is 180°

From the attached diagram, we have that:

A triangle ABC with angle 1, 2 and 3.

Line DE and AC are parallel and then BA is a traversal line.

Thus, the alternate interior angle is:

∠1 = ∠4

∠3 = ∠5

Therefore, the angle formed on line is:

∠4 + ∠2 + ∠5 = 180

∠1 + ∠2 + ∠3 = 180

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.

0.1(9) repeating as a decimal.

Answers

Answer:

  0.2

Step-by-step explanation:

You want to know the value of 0.199...repeating 9s.

Value

Let the value be represented by x:

  x = 0.1999...

Then 10x is ...

  10x = 1.9999...

The difference is ...

  10x -x = 1.9999... -0.1999... = 1.8

  9x = 1.8 . . . . . simplify

  x = 1.8/9 = 0.2

The value of the repeating decimal is 0.2.

Additional comment

The repeating decimal 0.99... is equivalent to 9/9 = 1. The repeating portion of 0.1999... has the value 0.1, Added to the first non-repeating digit, the sum is ...

Both of the above, and intends to capture at least five Space types d. All of the above and intends to capture at most four Electric Scooter types e. All of the above, and intends to capture at most three Rubber Duck type

Answers

The different types of Small Monsters combinations can the collector capture under that collector .lunder the following conditions are a) 593775 ; b) 100947 ; c) 27132 ; d) 30752 ; e) 26334.

For these questions as we are dealing with combination and repetition, we will be using the rule nC(r-1) where n = the number of total items and r = the number of ways we can choose.

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

= 593775

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

= 30752

e) All of the above and capture at most three Rubber Duck type, First, we will subtract the combination where we capture n = 20-3 (at most 3 rubber ducks) from the combination we have so ³⁰⁻¹⁴C₅ + ³⁰⁻¹⁵C₅ + ³⁰⁻¹⁶C₅ = 26334. Hence, required value is 26334.
