What is the area of a triangle with a base of 5x - 4 and a height of 2x +6?

Answers

Answer 1

The area of the triangle is 5x² + 11x -12 whose base is 5x - 4 and height is 2x + 6.

What is triangle?

A triangle is a two-dimensional geometric shape that is formed by three straight lines that connect three non-collinear points. The vertices are typically denoted by letters, such as A, B, and C. The three angles formed by the sides are also part of the triangle.

According to question:

The formula for calculating a triangle's area is:

Area = 1/2 x Base x Height

Plugging in the given values, we get:

Area = 1/2 x (5x - 4) x (2x + 6)

Simplifying, we get:

Area = 1/2 x (10x² + 22x - 24)

Distributing the 1/2, we get:

Area = 5x² + 11x - 12

Therefore, the area of the triangle is 5x² + 11x - 12.

The three lines are called the sides of the triangle, and the points where the sides meet are called the vertices of the triangle.

B. g(x)=6x^2+3 on 0≤x≤4

D. f(x) = (e^x)/x for 2 ≤ x ≤ 16.

Step 1: State the Extreme Value Theorem

The Extreme Value Theorem states that if a function is continuous on a closed interval [a,b], then the function must have a maximum and a minimum on the interval.

Step 2: Check for continuity and closed interval for each function

A. f(x) = 1/x on −10 ≤ x ≤ 10

The function f(x) = 1/x is continuous on the interval (-10, 0) and (0, 10).

However, since the interval given is [−10, 10], we see that the function is not continuous over the closed interval.

Hence the function does not satisfy the hypotheses of the Extreme Value Theorem.

B. g(x) = 6x^2+3 on 0 ≤ x ≤ 4

The function g(x) is continuous on the interval [0, 4].

Therefore, this function satisfies the hypotheses of the Extreme Value Theorem on the given interval.

C. k(x) = {3x^2+9 for 0 ≤ x < 2, 12x for 2 ≤ x ≤ 10} on 0 ≤ x ≤ 10

PLEASE HELP NOW!!! What would be the experimental probability of drawing a white marble?
Ryan asks 80 people to choose a marble, note the color, and replace the marble in Brianna's bag. Of all random marble selections in this experiment, 34 red, 18 white, 9 black, and 19 green marbles are selected. How does the theoretical probability compare with the experimental probability of drawing a white marble? Lesson 9-3

Answers

Answer:

25%

Step-by-step explanation:

The experimental probability of drawing a white marble can be found by dividing the number of times a white marble was chosen by the total number of trials:

Experimental probability of drawing a white marble = number of times a white marble was chosen / total number of trials

In this case, the number of times a white marble was chosen is 18, and the total number of trials is 80, so:

Experimental probability of drawing a white marble = 18/80 = 0.225 or 22.5%

To compare the experimental probability with the theoretical probability, we need to know the total number of marbles in the bag and the number of white marbles in the bag. Let's assume that there are 4 colors of marbles in the bag (red, white, black, and green), and that each color has an equal number of marbles. This means that there are a total of 4 x 18 = 72 marbles in the bag, and 18 of them are white.

The theoretical probability of drawing a white marble can be found by dividing the number of white marbles by the total number of marbles:

Theoretical probability of drawing a white marble = number of white marbles / total number of marbles

In this case, the number of white marbles is 18, and the total number of marbles is 72, so:

Theoretical probability of drawing a white marble = 18/72 = 0.25 or 25%

Comparing the two probabilities, we can see that the experimental probability (22.5%) is slightly lower than the theoretical probability (25%). This could be due to chance or sampling error in the experiment, or it could indicate that the actual probability of drawing a white marble is slightly lower than the theoretical probability.

Determine the length of the missing side of the given triangle. Round to the nearest tenth.
The hypotenuse is 7.7
The leg is 3.4

Answers

Answer:

6.9 or 7.0 .

Step-by-step explanation:

*Note that ^2 means raised to the power of two or squared

a^2 + b^2 = c^2

The hypotenuse is always the C, and the leg can be either a or b.

Fill in the blanks with the numbers that we have:

Hypotenuse: 7.7 | Leg: 3.4

3.4^2 + b^2 = 7.7^2

Square the numbers given

3.4 x 3.4 = 11.56

7.7 x 7.7 = 59.29, which leads us to:

11.56 + b^2 = 59.29

To find what b equals, we need to subtract 11.56 from 59.29

59.29 - 11.56 = 47.73

b^2 = 47.73

We need to take the square root of 47.73 to find b. b and b^2 are two different things.

The square root of 47.73 is about 6.90869017977. It asks for the answer to be rounded to the nearest tenth, giving us 6.9 or 7.0.

Jordan sells jewelry online. Monthly revenue varies as a function of the single price that Jordan sets for all pieces. Use vertex form to create a quadratic model for Jordon’s monthly revenue

Answers

Using the vertex form the quadratic model for Jordan's monthly revenue is y = 20 / 9(x - 13.5)² + 844.44.

We can use the vertex form of a quadratic equation to create a model for Jordan's monthly revenue:

y = a(x - h)² + k

where y is the monthly revenue, x is the price that Jordan sets for all pieces, and (h, k) is the vertex of the parabola. We can find the vertex by using the formula:

h = -b / 2a

where b and a are coefficients in the standard form of the quadratic equation (y = ax² + bx + c).

To get started, we can substitute two points from the given data to form a system of equations:

864 = a(12 - h)² + k

884 = a(13 - h)² + k

When we deduct the first equation from the second, we obtain:

20 = a(13 - h)² - a(12 - h)²

Simplifying, we get:

20 = a(25 - 24h + h²) - a(16 - 24h + h²)

20 = 9a(h² - 1)

Solving for a, we get:

a = 20 / 9(h² - 1)

Next, we can use the third point to solve for h:

896 = a(14 - h)² + k

Substituting the expression we found for a, we get:

896 = 20 / 9(h² - 1)(14 - h)² + k

Simplifying, we get:

h = 13.5

Now we can solve for k by substituting in the values we found for h and a:

864 = a(12 - h)² + k

k = 844.44

Finally, we can write the quadratic model for Jordan's monthly revenue using the values we found for h, k, and a:

y = 20 / 9(x - 13.5)² + 844.44

Therefore, the quadratic model for Jordan's monthly revenue is:

y = 20 / 9(x - 13.5)² + 844.44

Answers

The points determined by the real numbers 3.2, 9.5, 50, and 263 are all located on the unit circle at their respective distances from the origin.

The unit circle is a circle of radius 1 centered at the origin of a coordinate system, usually the Cartesian coordinate system. In this system, a point (x,y) is determined by its real number x, where x is the horizontal distance from the origin and y is the vertical distance from the origin. For example, the point determined by the real number 3.2 is located at (3.2, 0), since 3.2 is the horizontal distance from the origin. Similarly, the point determined by the real number 9.5 is located at (9.5, 0).

The point determined by the real number 50 is located at (50, 0). Finally, the point determined by the real number 263 is located at (263, 0). The unit circle is often used in trigonometry to describe the position of points on the circle with an angle in standard position (in radians). For example, if the point determined by the real number 3.2 has an angle in standard position of 3.2 radians, then the point located at (3.2, 0) on the unit circle is the same point. Similarly, if the point determined by the real number 9.5 has an angle in standard position of 9.5 radians, then the point located at (9.5, 0) on the unit circle is the same point. The same is true for the points determined by the real numbers 50 and 263, respectively.

Suppose the entire pink arc measures 200 degrees and the entire blue arc measures 50 degrees, what would be measure of the manilla angle be?​​

Move the pink point so it becomes tangent to the circle

Answer #1 within this context​

Answers

The answer of the given question based on the circle on finding the measure of the manilla angle the answer will be  the measure of the manila angle is 110° degrees.

What is Circle?

A circle is  closed, two-dimensional shape that consists of all points in  plane that are equidistant from  given point, called center of the circle. The distance from  center to any point on circle is called  radius of the circle.

The circumference of  circle is distance around the circle, and it is equal to 2π times radius. Circles are fundamental concept in geometry and are used in many fields, like physics, engineering, and architecture. They are also used to represent cycles, cycles of time, and the cyclical nature of life.

If the entire pink arc measures 200° degrees and the entire blue arc measures 50° degrees, then the sum of the measures of the three arcs (pink, blue, and manila) is 360° degrees, which is the total measure of a circle.

To find the measure of the manila angle, we need to subtract the measures of the pink and blue arcs from 360° degrees:

360° degrees - 200° degrees - 50° degrees = 110° degrees

Therefore, the measure of the manila angle is 110° degrees.

Define sampling model

A sampling model is a statistical model used to describe the behavior of a sample statistic. In other words, it is a model that describes the distribution of a particular sample statistic, such as the mean or standard deviation, as it is repeatedly sampled from a population.

When a sample is drawn from a population that is strongly skewed to the left, a small sample may not accurately represent the true population mean. However, if a large sample is taken, the sample mean is more likely to be normally distributed, due to the central limit theorem. This means that both statement I and II are true.

Statement III is false because as the sample size increases, the variability of the sample means actually decreases. This is because larger samples tend to have less sampling error and are more representative of the population as a whole.

he tree nearest the house is our starting point. Our point person is taking the clinometer reading 15.24 meters from the tree's base and they get a reading of 237`. Our point person is 1.83 meters in height.

How tall is the tree, rounded to the nearest meter?The height of the tree can be determined by using the tangent formula. The tangent formula is tan θ = h/d where θ = angle of elevation, h = height of the object, and d = horizontal distance.

The clinometer reading is the angle of elevation. Hence, we can use the given data to determine the height of the tree.The point person is standing at 15.24 m from the base of the tree. Therefore, the horizontal distance (d) is 15.24 m. The angle of elevation (θ) is 237 degrees (given in the question).

Convert the degrees to radians as tan function uses radians. Convert degrees to radians:[tex]237 × (π/180) = 4.135[/tex]radians.Now we can use the tangent formula to determine the height of the tree:tan θ = h/dtan 4.135 = [tex]h/15.24h = 15.24 × tan 4.135h = 15.24 × 0.07311h ≈ 1.1132[/tex] metersThe height of the tree is 1.1132 meters.

The bakers at healthy bakery can make 190 bagels in 10 hours. How many bagels can they make in 17 hours? What is the rate per hour?

Answers

The cookers at healthy Bakery could make 323 bagels in 17 hours, and their rate is 19 bagels according to hour.

To find out how many bagels the cookers could make in 17 hours, we will use the unitary method, which involves finding the rate at which the cookers can make bagels and additionally multiplying that price through the wide variety of hours labored.

Let the rate at which the cookers can make bagels be r bagels in line with hour. We also can set up the subsequent share

190 bagels/ 10 hours = r bagels 1 hour

Simplifying this proportion, we get

r = 190 bagels/ 10 hours

r = 19 bagels/ 1 hour

So the cookers can make 19 bagels in keeping with hour.

To find out how many bagels they could make in 17 hours, we can multiply the rate via the number of hours

19 bagels/ hour × 17 hours = 323 bagels

Therefore, the cookers at healthy Bakery could make 323 bagels in 17 hours, and their rate is 19 bagels according to hour.

To rewrite the quadratic equation in the form y = a(x - p)²+q, we need to complete the square.

y = 2x^2 + 16x + 26

y = 2(x^2 + 8x) + 26

y = 2(x^2 + 8x + 16 - 16) + 26 // Adding and subtracting (8/2)^2 = 16 inside the parentheses

y = 2((x + 4)^2 - 16) + 26

y = 2(x + 4)^2 - 32 + 26

y = 2(x + 4)^2 - 6

Therefore, the quadratic equation y = 2x ^ 2 + 16x + 26 rewritten in the form y = a(x - p)²+q is y = 2 * (x + 4) ^ 2 - 6, so the answer is D

Answer:

y= 2(x+4)^2 -6

Step-by-step explanation:

y= 2x^2 + 16x + 26

It is in the form y= ax^2 + bx + c

To rewrite in the form y=a(x-p)^2 + q

We need to fin p and q. We already have a in the original equation.

In y= 2x^2 + 16x + 26,    a=2.

The formula say that:  p=-b/2a

p= -16/(2*2)

p=-16/4

p=-4

In the formula, we replace a and  y= 2(x-(-4))^2 +q

Obtaining, y= 2 (x+4)^2 + q

Now, to find q we need to obtain a point from the original equation. Commonly the y-intercept. In the form y= ax^2 + bx + c ; C is the y-intercept.

y-intercept: (0,c)

Therefore, in y= 2x^2 + 16x + 26

y-intercept: (0,26)

In the equation we already have:

y= 2(x+4)^2 +q

26= 2(0+4)^2 + q

26=2(4)^2 +q

26= 2(16) + q

26= 32 + q

-6 = q

Joining all the results, we obtain:

y= 2(x+4)^2 -6

a normal distribution is observed from the times to complete an obstacle course. the mean is 69 seconds and the standard deviation is 6 seconds. using the empirical rule, what is the probability that a randomly selected finishing time is greater than 87 seconds? provide the final answer as a percent rounded to two decimal places. provide your answer below: $$ %

Answers

The probability that a randomly selected finishing time is greater than 87 seconds is 14.08%. This can be calculated using the empirical rule.


The empirical rule states that for any data that is normally distributed, about 68% of the data will fall within one standard deviation of the mean (in this case, within 69 ± 6 seconds). Approximately 95% of the data will fall within two standard deviations (in this case, within 69 ± 12 seconds), and about 99.7% of the data will fall within three standard deviations (in this case, within 69 ± 18 seconds).Given the mean and standard deviation given, we can calculate the probability that a randomly selected finishing time is greater than 87 seconds.

We can do this by subtracting the area under the curve from the mean to the value we are interested in (in this case, 87 seconds). Since the total area under the curve is 1, subtracting the area from the mean to 87 seconds will give us the desired probability.To calculate the area under the curve, we need to calculate the Z-score, which is the number of standard deviations away from the mean a particular value is. In this case, the Z-score is (87 - 69) / 6, which is 2.16. Using a Z-table, the probability of a Z-score of 2.16 or higher is 0.8592. Therefore, the probability that a randomly selected finishing time is greater than 87 seconds is 1 - 0.8592, which is 0.1408. Rounding to two decimal places, this is 14.08%.

Find the equation of a line that passes through the points (1,3) and (2,2). Leave your answer in the form
y
=
m
x
+
c

Answers

The equation of the line that passes through the points (1,3) and (2,2) is y = -x + 4.

To find the equation of the line, we can use the slope-intercept form of a linear equation, y = mx + c, where m is the slope and c is the y-intercept.

First, we need to find the slope of the line. The slope is given by:

m = (y2 - y1)/(x2 - x1)

where (x1, y1) and (x2, y2) are the coordinates of the two given points. Plugging in the values, we get:

m = (2 - 3)/(2 - 1) = -1

Next, we can use one of the given points and the slope to find the y-intercept. Using the point (1,3), we get:

3 = (-1)(1) + c

Simplifying this equation gives us:

c = 4

Therefore, the equation of the line in slope-intercept form is:

y = -x + 4.

You are sitting in a classroom next to the wall looking at the blackboard at the front of the room. The blackboard is 12 ft
long and starts 3 ft from the wall you are sitting next to. Show that your viewing angle is
a=cot^-1 x/15 - cot^-1 x/3
if you are a ft from the front wall.

Answers

The viewing angle a of a person sitting a distance x from the front wall of a classroom with a blackboard that is 12 ft long and starts 3 ft from the wall they are sitting next to can be calculated as: a = cot-1(x/15) - cot-1(x/3)


To understand this calculation, let's consider a diagram of the classroom.

We can see from the diagram that the blackboard has length 12 ft, starting 3 ft from the wall the student is sitting next to. The student is sitting a distance x from the front wall.

The viewing angle a is the angle between the wall the student is sitting next to and the line from the student to the front wall. This angle can be calculated using the tangent of the opposite side (front wall) and adjacent side (wall the student is sitting next to).

We can therefore write: a = tan-1(12/3) - tan-1(x/3)

Simplifying this equation, we can rewrite it as: a = cot-1(x/15) - cot-1(x/3).

Answers

The better understanding of the data, making it easier to draw conclusions and make decisions based on the data.

In statistics, the spread of the data is used to describe the variability or deviation of a set of data. The location of the data is used to determine the center of the data, and the shape of the data describes the distribution of the data. When it comes to the variable number of care types sp unable to get (acv nocarsum), the data should be analyzed using the appropriate graph(s) and descriptive statistics to determine its shape, location, and spread.
Descriptive statistics:
In descriptive statistics, measures such as mean, mode, median, standard deviation, variance, and range are used to analyze data. These statistics provide a summary of the data in the form of numerical values, making it easy to identify patterns, outliers, and other characteristics of the data.
Graphs:
Graphs are also used in statistical analysis to visually represent the data. There are different types of graphs that can be used, depending on the type of data being analyzed. Commonly used graphs in statistical analysis include histograms, scatterplots, boxplots, and line graphs.
To describe the shape, location, and spread of the data for the number of care types sp unable to get (acv nocarsum) variable, the following steps should be followed:

Step 1: Collect the data.
The first step is to collect the data on the number of care types sp unable to get (acv nocarsum) variable. This data can be obtained from various sources such as surveys, questionnaires, or observational studies.

Step 2: Determine the center of the data.
The center of the data can be determined using measures such as mean, mode, or median. The mean is the average of the data, while the median is the middle value of the data when arranged in order of magnitude. The mode is the value that appears most frequently in the data.

Step 3: Determine the variability of the data.
The variability of the data can be determined using measures such as variance or standard deviation. The variance is the average of the squared differences between each data point and the mean, while the standard deviation is the square root of the variance.

Step 4: Determine the shape of the data.
The shape of the data can be determined using graphs such as histograms, boxplots, or line graphs. Histograms show the distribution of the data, while boxplots show the quartiles and outliers of the data.

Step 5: Interpret the results.
Once the data has been analyzed using the appropriate graph(s) and descriptive statistics, the results should be interpreted to describe the shape, location, and spread of the data for the number of care types sp unable to get (acv nocarsum) variable. This will provide a better understanding of the data, making it easier to draw conclusions and make decisions based on the data.

Say my population is USA voters. If I interviewed people in front of a major grocery supermarket. Making sure that I selected supermarkets in high median salary areas. What type of sampling best fits my experiment?

Answers

The sampling method that best fits your experiment is convenience sampling.

Describe Sampling?

Sampling is the process of selecting a subset of individuals or items from a larger population in order to gather information and draw conclusions about the entire population. Sampling is often used in scientific research, market research, and other fields where it is impractical or impossible to measure the entire population.

There are many different types of sampling methods, including random sampling, stratified sampling, cluster sampling, and convenience sampling. Each method has its own advantages and disadvantages, and the choice of sampling method depends on the specific research question and the resources available.

The sampling method that best fits your experiment is convenience sampling. Convenience sampling is a non-probability sampling method that involves selecting individuals who are readily available and accessible to the researcher. In your case, you are selecting individuals who are present in front of a major grocery supermarket, which is a convenient location. Convenience sampling is often used in situations where it is difficult or impractical to obtain a random sample, and is commonly used in market research and pilot studies.

However, it is important to note that convenience sampling has some limitations. Since the sample is not randomly selected, it may not be representative of the population as a whole. In your case, selecting supermarkets in high median salary areas may introduce bias into the sample, as it may not accurately represent the entire population of USA voters. Additionally, the sample size and characteristics may be affected by factors such as time of day, day of the week, and other factors that may affect who is present in front of the supermarket at a given time. Therefore, the results obtained from this sampling method may not be generalizable to the entire population of USA voters.

The length of side x can be calculated using the Pythagorean theorem, which states that the sum of the squares of the two shorter sides of a right triangle is equal to the square of the longest side.

What is length?

Length is the linear distance between two points. It is a fundamental concept in geometry, physics, and many other sciences. In mathematics, length is defined as the magnitude of a line segment, which is the distance between two points. In physics, length is the distance an object moves in a given direction, or the distance an object has traveled during a given period of time.

In this case, the longest side would be x and the two shorter sides would be 2. Therefore, x2 = 22 + 42, which simplifies to x2 = 20. This means that x = √20, which can be written in simplest radical form with a rational denominator as x = 10√2.

Answers

Answer: Yes, the Mean Value Theorem can be applied to f(x) = 9x^3 on the closed interval [1, 2].

To find all values of c in the open interval (1, 2) such that f'(c) = (f(b) - f(a))/(b - a), we first find the derivative of f(x):

f'(x) = 27x^2

Then, we can use the Mean Value Theorem to find a value c in the open interval (1, 2) such that:

f'(c) = (f(2) - f(1))/(2 - 1)

27c^2 = 9(2^3 - 1^3)

27c^2 = 45

c^2 = 5/3

c = +/- sqrt(5/3)

Therefore, the values of c in the open interval (1, 2) such that f'(c) = (f(b) - f(a))/(b - a) are:

c = sqrt(5/3), -sqrt(5/3)

Note that these values are not in the closed interval [1, 2], as they are not between 1 and 2, but they are in the open interval (1, 2).

Answers

The publication of three major books on race in chronological order, from earliest to most recent is:

- Micheal Omi and Howard Winant wrote about the social construction of race in Racial Formation in the United States.- Tomas Almaguer wrote about historical race relations in California in Racial Fault Lines.- Ta- Nehisi Coates wrote about race and the African American experience in Between the World and Me.

Chronological order is the listing, description, or discussion of when events occurred in relation to time. Essentially, it is similar to looking at a chronology to see what happened initially and what happened after that. For example, if teachers asked their pupils to recount their first day of school, they would expect students to begin by waking up that morning and getting ready. If pupils begin from the time they enter the school, significant information is lost and the listener may become confused due to a lack of knowledge.

Helping pupils grasp what chronological order is and how to use the skill correctly can benefit students ranging from kindergarten to collegiate levels. The concept may appear simple, yet failing to master chronological sequence can cause kids to struggle academically and lack a solid educational foundation.

An urn contains eight green balls and six red balls. Four balls are randomly selected from the urn in succession, with replacement. That is, after each draw the selected ball is returned. What is the probability that all four balls drawn are red. Round your answer to three decimal places

Answers

The probability of drawing four red balls in succession, with replacement, is 0.04 or 4%.

Since we are replacing the ball after each draw, the probability of drawing a red ball remains the same for each draw. The probability of drawing a red ball on any given draw is:

P(Red) = Number of Red Balls / Total Number of Balls

P(Red) = 6 / (8 + 6)

P(Red) = 0.4286

So, the probability of drawing four red balls in a row is the product of the probability of drawing a red ball four times in a row:

P(4 Red Balls) = P(Red) * P(Red) * P(Red) * P(Red)

P(4 Red Balls) = 0.4286 * 0.4286 * 0.4286 * 0.4286

P(4 Red Balls) = 0.04 or 4%

Find an expression that is equivalent to (a - b) ^ 3

Answers

An expression equivalent to (a - b)³ is a³ - 3a²b + 3ab² - b³.

What other expressions are the same as 2 5?

The fractions 4/10, 6/15, 8/20, etc. are identical to 2/5. In the reduced form, equivalent fractions have the same value. Explanation: When writing equivalent fractions, the numerator and denominator should be multiplied or divided by the same number.

One way to expand (a - b)³ is to use the binomial formula:

(a - b)³ = C(3,0) * a³ * (-b)^0 + C(3,1) * a² * (-b) + C(3,2) * a * (-b)² + C(3,3) * a * (-b)³

where C(n,k) denotes the number of ways there are to select k objects from a set of n objects, and "n choose k" is the binomial coefficient.

Simplifying the above expression, we get:
