how do i write a linear equation to represent this relationship

How Do I Write A Linear Equation To Represent This Relationship

Answers

Answer 1

Note that the linear equation that represents this relationship is y = -3x + 9.

What is the explanation for the above response?

To write a linear equation to represent this relationship, we need to find the slope and y-intercept of the line that passes through the given points.

Using the formula for slope, we have:

slope = (change in y) / (change in x)

= (0 - 9) / (3 - 0)

= -3

Now we can use the point-slope form of a linear equation, y - y1 = m(x - x1), where m is the slope and (x1, y1) is any point on the line. Let's use the point (0, 9):

y - 9 = -3(x - 0)

Simplifying, we get:

y - 9 = -3x

Adding 9 to both sides, we get:

y = -3x + 9

Therefore, the linear equation that represents this relationship is y = -3x + 9.

Write the function in the form f(x) = (x − k)q(x) + r for the given value of k. F(x) = x3 − x2 − 10x + 5, k = 3

Answers

The formula for the function f(x): (x-  k)q(x) + r for the specified value of k. F(x) = x3 − x2 − 10x + 5, k = 3 is f(x) = (x - 3)([tex]x^2[/tex] + 2x - 1) - (4x - 5).

To write the function in form f(x) = (x − k)q(x) + r, we need to divide the given polynomial by (x-k) using long division. Here's the long division process:

           [tex]x^2[/tex] + 2x - 1

   ----------------------

x - 3 | [tex]x^3[/tex] - [tex]x^2[/tex] - 10x + 5

Therefore, we have:

f(x) = (x - 3)([tex]x^2[/tex] + 2x - 1) - (4x - 5)

Thus, the function with the formula f(x)= (x-k)q(x) + r for k= 3 is:

can someone help me solve the area of this composite figure please

Answers

Therefore, the area of the composite figure is 65 square centimeters. Therefore, the area of the composite figure is approximately 150.8 square centimeters.

What is area?

In mathematics, the area is the measure of the size of a two-dimensional surface or shape. It is the amount of space inside the boundary of a flat object, such as a triangle, rectangle, circle, or any other polygon. The standard unit of measurement for area is square units, such as square meters (m²), square centimeters (cm²), or square feet (ft²). To calculate the area of a shape, we usually use a formula that depends on the shape's geometry and dimensions, such as its length, width, radius, or height. Area has many applications in everyday life, such as calculating the size of a room, the amount of paint needed to cover a wall, or the area of land required to build a house or grow crops. In mathematics and science, area is also used to solve problems in geometry, physics, engineering, and other fields.

Here,

1. Combination of Square and Rectangle

To find the area of this composite figure, we need to break it down into simpler shapes and add up their areas. The figure consists of a square with sides of 5 cm, a rectangle with sides of 4 cm and 9 cm, and a square with sides of 2 cm.

The area of the square with sides of 5 cm is:

A1 = (side)²

= (5 cm)²

= 25 cm²

The area of the rectangle with sides of 4 cm and 9 cm is:

A2 = length x width

= (9 cm) x (4 cm)

= 36 cm²

The area of the square with sides of 2 cm is:

A3 = (side)²

= (2 cm)²

= 4 cm²

To find the total area of the composite figure, we add up the areas of these three shapes:

A = A1 + A2 + A3

A = 25 cm² + 36 cm² + 4 cm²

A = 65 cm²

Two bags contain white and yellow balls. Bag 1 contains two white balls and four yellow balls. Bag 2 contains four white balls and five yellow balls. A ball is drawn at random from each container. What is the probability that both balls are white?

A. 1/9
B. 1/6
C. 4/27
D. 10/201​

Answers

Answer:

C. 4/27

Step-by-step explanation:

Let's use the multiplication rule of probability to calculate the probability that both balls drawn are white:

P(white ball from Bag 1) = 2/6 = 1/3

P(white ball from Bag 2) = 4/9

Therefore, the probability of drawing a white ball from each bag is:

P(white from Bag 1 and white from Bag 2) = P(white from Bag 1) * P(white from Bag 2)

= (1/3) * (4/9)

= 4/27

So, the answer is C. The probability that both balls are white is 4/27.

Levi Hempke wants to buy a car costing $21,000. He will finance the pu rchase with an installment loan from the bank, but he would like to finance no more than$14,280. What percent of the car's total cost should his down payment be?

Answers

Therefore , the solution of the given problem of percentage comes out to be down payment is 32% of the overall cost of the vehicle.

What is percentage, exactly?

In statistics, a% is a number or value that is expressed as a fraction of 100. The terms "pct.," "pct.," but also "pc" are also infrequently used. Nevertheless, the symbol "%" is frequently used to indicate it. The percentage sum is flat; there are no dimensions. Since the numerator of a percentage is always 100, percentages truly constitute integers. Either the percent symbol (%) or the word "percent" must come before a number to denote that it is a percentage.

Here,

Levi Hempke wishes to borrow a maximum of $14,280 to finance a $21,000 vehicle. Consequently, he intends to put down:

=> $21,000 - $14,280 = $6,720

We must divide his down payment by the total cost of the car, multiply by 100 to convert to a percentage, and

then determine the percentage of the total cost of the car that he should put down:

=>  ($6,720 ÷ $21,000) × 100 = 32%

Levi's down payment should therefore equal 32% of the overall cost of the vehicle.

2000 people lived in a village in the year 1999. By the year 2004 ,the male were increased by 10% and the women decreased by 6%. But the total population remain unchanged. How many males lived in the village by 1999?

Answers

The number of males in the village in 1999 was 1200, given that the male to female ratio was 3:5 and the total population was 2000.

Let's assume that in the year 1999, there were M males and W females living in the village, so the total population would be P = M + W = 2000.

Then, in the year 2004, the male population increased by 10%, so the number of males became 1.1M, and the female population decreased by 6%, so the number of females became 0.94W.

The total population remained unchanged, so we have:

1.1M + 0.94W = P = 2000

We also know that P = M + W, so we can substitute this into the above equation:

1.1M + 0.94W = M + W

0.1M = 0.06W

M/W = 3/5

So the ratio of males to females in the village in 1999 was 3:5. Therefore, we can write:

M + W = 2000

3/5 (M + W) = 3/5 (2000)

M = 1200

Therefore, there were 1200 males living in the village in the year 1999.

We can check that this answer is consistent with the information given in the problem. In 1999, there were 2000 people in the village, and the ratio of males to females was 3:5. This means that the number of males is 3/8 of the total population, and the number of females is 5/8 of the total population:

Number of males = 3/8 x 2000 = 750

Number of females = 5/8 x 2000 = 1250

Now let's apply the changes that occurred between 1999 and 2004. The male population increased by 10%, so the new number of males is:

1.1 x 750 = 825

The female population decreased by 6%, so the new number of females is:

0.94 x 1250 = 1175

The total population is:

825 + 1175 = 2000

So the total population remained unchanged, as required by the problem statement. Therefore, our answer of 1200 males in 1999 is consistent with the information given in the problem.

A multivitamin constaions. 17g of vitamin C. How much vitamin c does 60 tablets contain? answer in milligrams

Answers

60 tablets of the multivitamin, with 17g (17,000mg) of vitamin C per tablet, contains 1,020,000mg of vitamin C in total.

If one tablet of the multivitamin contains 17g of vitamin C, then 60 tablets would contain 60 times that amount:

60 tablets x 17g of vitamin C per tablet = 1020g of vitamin C

However, it is more common to express vitamin C (and other nutrients) in milligrams (mg) rather than grams (g). To convert from grams to milligrams, we can multiply by 1000:

1020g of vitamin C x 1000 mg/g = 1,020,000 mg of vitamin C

Therefore, 60 tablets of the multivitamin contain 1,020,000 mg of vitamin C.

Just to clarify, in the answer above, I made a mistake in the units. 17g is actually 17,000mg, not 17mg. So the correct calculation is:

If one tablet of the multivitamin contains 17,000mg of vitamin C, then 60 tablets would contain 60 times that amount:

60 tablets x 17,000mg of vitamin C per tablet = 1,020,000mg of vitamin C

Find the area of the triangle with vertices (10, 1), (7, 11), and (7, 1).

Answers

The area of the triangle is 15 square units.

What is area of triangle?

The area of a triangle is a measure of the size of the region enclosed by the three sides of the triangle. The formula for finding the area of a triangle depends on the length of its base and height, which are usually denoted by "b" and "h", respectively.

We can find the area of the triangle with vertices (10, 1), (7, 11), and (7, 1) by using the formula for the area of a triangle:

area = (1/2) * base * height

where the base is the distance between the two points with the same y-coordinate, and the height is the distance from the third point to the line that contains the base.

The base is a vertical line segment with length 11 - 1 = 10, since the two points (7, 11) and (7, 1) have the same y-coordinate.

The height is the distance from the point (10, 1) to the line that contains the base. Since the line is vertical and passes through the point (7, 1), the distance is simply the difference between the x-coordinates of the two points: 10 - 7 = 3.

Substituting these values into the formula, we get:

area = (1/2) * 10 * 3

    = 15

Therefore, the area of the triangle is 15 square units.

Answer:

Area = π*r^2

Area = 113.1 units^2

Step-by-step explanation:

The figure drawn is a circle.  The ancient Greeks devised an approximation of the area of circles by dividing the circle into a series of small triangles with their peaks at the center of the circle and their bases  are formed by the curve of the circle.  Although this means there is an error because the circumference is not a straight line, they made the triangles small enough so that the error would be minimized.  They found that the area of the circle was related to it's radius by the expression: Area = π*r^2.  

Without retracing their steps, let's simply use the formula that is now the accepted measure of the area of a circle.  Pi (π) is 3.14 to 3 decimal places.  Far more accurate values are known, but 3.14 offers reasonable accuracy, assuming this is not intended for space flight.

Los dos números que multiplicados den 30 son 5 y 6. Para encontrar dos números que sumados o restados den -11, debemos verificar todas las posibles combinaciones. Al hacerlo, descubrimos que -5 y -6 sumados dan -11. Por lo tanto, los dos números son 5 y -6.

The answer is 29 because 30-11=29

In particular, you will compare the AVERAGE PROFITABILITY for customers with INCOME < 40,000 with customers whose income > = 40,000. Ignore missing values in this analysis (leave them as they are as you complete this analysis and do NOT eliminate records with INCOME missing) and let the EXCEL IF function treat missing values by default. Which of the following is a FIRST STEP towards completing this analysis?

Answers

The formulas will calculate the average profitability for customers with income < 40,000 and those with income >= 40,000 respectively.

The first step towards completing the given analysis is to create two groups of customers based on their income levels. The groups should consist of customers with income < 40,000 and those with income > = 40,000. The detailed explanation is provided below:Step-by-step explanation:Here, we need to compare the average profitability of two groups of customers based on their income levels, one with income less than 40,000 and the other with income greater than or equal to 40,000.The first step towards completing this analysis is to create two groups of customers based on their income levels. The groups should consist of customers with income < 40,000 and those with income > = 40,000. This can be achieved using the following steps:1. Open a new Excel workbook and import the dataset that needs to be analyzed.2. Once the data is imported, create a new column named 'Income Group' that will classify customers into the two groups based on their income level. To do this, we can use the following formula: =IF(B2<40000,"<40,000",">=40,000")Here, B2 is the cell that contains the income value of the first customer.3. Drag the formula down to the last cell in the column to apply it to all customers. This will create two groups of customers based on their income levels.4. Now, we need to calculate the average profitability of each group. To do this, we can use the following formula: =AVERAGEIF(C2:C11,"<40,000",D2:D11) and =AVERAGEIF(C2:C11,">=40,000",D2:D11)Here, C2:C11 contains the income group values, D2:D11 contains the profitability values, and "<40,000" and ">=40,000" are the criteria for each group. These formulas will calculate the average profitability for customers with income < 40,000 and those with income >= 40,000 respectively.

5) (8 pts) A company’s design of 45-ohm resistors is believed to be manufactured with a standard deviation of 0.12 Ω. To evaluate this, a sample of 15 resistors was collected and the standard deviation of the resistance of these 15 resistors was 0.194 Ω. a) (6 pts) Calculate a 95% two-sided confidence interval for standard deviation of resistance, σ. b) (2 pts) Based on your answer to part (a), is it reasonable to believe that the standard deviation of all resistors produced is 0.12 Ω? Explain your answer using information from part (a).

Answers

The true value of the standard deviation may be in the interval of (0.12, 0.3757), it may or may not be 0.12 Ω.

Calculation of a 95% two-sided confidence interval for standard deviation of resistance, σ95% two-sided confidence interval for standard deviation of resistance is given by:\[\left(\sqrt{\frac{\left(n-1\right)s^2}{\chi_{0.025,n-1}^2}},\sqrt{\frac{\left(n-1\right)s^2}{\chi_{0.975,n-1}^2}}\right)\]where s = 0.194 Ω, n = 15, and Χ² distribution with df = 14 at α = 0.05/2 = 0.025/0.975The range of the 95% two-sided confidence interval for the standard deviation of resistance is given as follows:95% two-sided confidence interval for standard deviation of resistance = (0.12, 0.3757)Hence, the 95% two-sided confidence interval for the standard deviation of resistance is given as (0.12, 0.3757).b) Explanation:The standard deviation of the resistance is believed to be 0.12 Ω. From the 95% confidence interval obtained in part (a), 0.12 Ω is not within the 95% confidence interval. This means it is not reasonable to believe that the standard deviation of all resistors produced is 0.12 Ω. Since the true value of the standard deviation may be in the interval of (0.12, 0.3757), it may or may not be 0.12 Ω.
