Answer 1

Answer:

-2, 2

-4

Step-by-step explanation:

The x-intercept is the point where the graph crosses the x-axis. At that point, the y-coordinate equals zero. At the x-intercept, f(x) = 0.

Look below f(x) and find where f(x) = 0. Which x values correspond to f(x) = 0?

There are two x values: x = -2, and x = 2

The x-intercepts shown in the table are -2 and 2.

The y-intercept is the point where the graph crosses the y-axis. At that point, the x-coordinate equals zero. At the y-intercept, x = 0.

Look below x and find where x = 0. Which f(x) value corresponds to x = 0?

There is one f(x) value: f(x) = -4

The y-intercept shown in the table is -4.

If you have a rectangle with a length of 5 and a width of 3, the area would be 5 * 3 = 15.

To factorise a quadratic equation, you need to find two numbers that multiply to give the constant term and add to give the coefficient of the x term.

For example, if you have the equation x^2 + 5x + 6 = 0, the two numbers you need to find are 2 and 3, because 2 * 3 = 6 and 2 + 3 = 5. So the equation can be factorised as (x + 2)(x + 3) = 0.

Homework:6.3 Applications of Systems of Linear Equations Question 4, 6.3.13-BE
Part 1 Jim took clothes to the cleaners three times last month.​ First, he brought 3 shirts and 2 pairs of slacks and paid $18.45. Then, he brought 7 shirts, 2 pairs of​ slacks, and 1 sports coat and paid $35.40. ​Finally, he brought 4 shirts and 2 sports coats and paid ​$23.94. How much was he charged for each​ shirt, each pair of​ slacks, and each sports​ coat?
Jim was charged​$____ for each​ shirt, ​$____for each pair of​ slacks, and ​$____for each sports coat.

Answers

Therefore, it is not possible to determine how much Jim was charged for each shirt, each pair of slacks, and each sports coat with the given information.

To solve this problem, we can use a system of linear equations. Let x be the cost of each shirt, y be the cost of each pair of slacks, and z be the cost of each sports coat. Then we can write the following equations based on the information given in the problem:

3x + 2y = 18.45 (equation 1)

7x + 2y + z = 35.40 (equation 2)

4x + 2z = 23.94 (equation 3)

Now we can use the elimination method to solve for the variables. First, we can subtract equation 1 from equation 2 to eliminate the y variable:

4x + z = 16.95 (equation 4)

Next, we can multiply equation 1 by -2 and add it to equation 3 to eliminate the y variable:

-6x - 4y + 4x + 2z = -36.9 + 23.94

-2x + 2z = -12.96 (equation 5)

Now we can subtract equation 4 from equation 5 to eliminate the x variable:

2z - z = -12.96 - 16.95

z = -29.91

This value for z does not make sense, so there must be a mistake in the calculations or the original problem. Therefore, it is not possible to determine how much Jim was charged for each shirt, each pair of slacks, and each sports coat with the given information.

prove the following:
1. the altitudes of a triangle are the angle bisectors of the orthic triangle
2. the circle whose diameter is the side of the triangle passes through the opposite vertices of the orthic triangle

Answers

The altitudes of a triangle are the angle bisectors of the orthic triangle is true because the orthic triangle is formed by the feet of the altitudes of the original triangle. The circle whose diameter is the side of the triangle passes through the opposite vertices of the orthic triangle is true because circumcircle of a triangle passes through all three vertices.

To prove the first statement, we can use the fact that the altitudes of a triangle are perpendicular to the sides and intersect at the orthocenter. The orthic triangle is formed by the feet of the altitudes of the original triangle.
1. Let ABC be the original triangle and D, E, F be the feet of the altitudes from A, B, and C, respectively.
2. Since AD is an altitude, ∠ADB and ∠ADC are right angles.
3. Similarly, ∠BEC and ∠BFC are right angles.
4. Therefore, ∠BDC and ∠EDF are supplementary angles, meaning they add up to 180 degrees.
5. Since ∠BDC and ∠EDF are supplementary and they share a common side, they are also the angle bisectors of the orthic triangle DEF.
6. The same logic can be applied to the other two altitudes to show that they are also angle bisectors of the orthic triangle.

To prove the second statement, we can use the fact that the circumcircle of a triangle passes through all three vertices.
1. Let ABC be the original triangle and D, E, F be the feet of the altitudes from A, B, and C, respectively.
2. Let O be the circumcenter of the original triangle ABC.
3. Since the circumcircle passes through all three vertices, OD, OE, and OF are all radii of the circle.
4. Since all radii of a circle are equal, OD = OE = OF.
5. Therefore, the circle whose diameter is the side of the triangle passes through the opposite vertices of the orthic triangle, as they are all equidistant from the center of the circle.

In response to the supplied query, we may state that Hence, Brenda's Pythagorean theorem home is around 7.2 kilometers away from the school.

what is Pythagorean theorem?

The fundamental Euclidean geometry relationship between the three sides of a right triangle is the Pythagorean Theorem, sometimes referred to as the Pythagorean Theorem. This rule states that the areas of squares with the other two sides added together equal the area of the square with the hypotenuse side. According to the Pythagorean Theorem, the square that spans the hypotenuse (the side that is opposite the right angle) of a right triangle equals the sum of the squares that span its sides. It may also be expressed using the standard algebraic notation, a2 + b2 = c2.

Points A, B, and C can be used to create a right triangle in this situation. The hypotenuse of the line segment between points A and C is its length, while the other two sides are the lengths of the segments connecting A and B and B and C.

We'll refer to the separation between positions A and C as "x". Next, we have:

Assume that support the ballot measure in Region B is 0. 51 What is the probability that , measure might pass?

Answers

The probability that the proportion of voters in the sample of Region A who support the ballot measure is greater than 0.50 is approximately 0.1736 or 17.36%. The probability that the ballot measure might pass in Region B can be calculated using a confidence interval approach.

The confidence interval for the population proportion of voters who support the ballot measure in Region B:

CI = p ± z × SE

where p is the sample proportion, z is the critical value for the desired confidence level (e.g., z=1.96 for 95% confidence), and SE is the standard error of the sample proportion.

the standard error of the sample proportion:

SE = [tex]sqrt [p ×\frac{(1-p)}{n} ][/tex]  = [tex]sqrt[0.51 ×\frac{(1-0.51)}{400} ][/tex] = 0.025

where p is the sample proportion and n is the sample size.

the confidence interval using a 95% confidence level:

CI = 0.51 ± 1.96  0.025 = (0.46, 0.56)

Therefore, we can be 95% confident that the true population proportion of voters who support the ballot measure in Region B falls within the range of 0.46 to 0.56. Since the lower bound of the confidence interval is above 0.50, there is a possibility that the ballot measure might pass in Region B. However, the exact probability would depend on the actual population proportion and the sample size.

From point A, Stanley walks 200 m due east to point B. From B, he then walks 160 m due south to point C. Work out the length of AC. Give your answer correct to 3 significant figures

Answers

The length of AC is 224 meters to 3 significant figures.


a² + b² = c²

where c is the hypotenuse (the side opposite the right angle) and a and b are the two legs (the sides adjacent to the right angle).

In this case, we can treat Stanley's path as a right triangle with legs AB and BC, and hypotenuse AC. Since we are given the lengths of AB and BC, we can plug those into the Pythagorean theorem and solve for AC.

AC² = AB² + BC²

AC² = (200 m)² + (160 m)

AC² = 40,000 m² + 25,600 m²

AC² = 65,600 m²

To find AC, we take the square root of both sides:

- $150.40
-$148.50

Answers

The amount of overtime that Diego would earn would be D. $ 148. 50.

How to find the overtime ?

Diego's regular rate is $11 per hour. When he works overtime, he is paid time-and-a-half of his regular rate, which means he earns an additional 50% of his regular rate for each hour of overtime.

So his overtime rate is:

= 11 + ( 11 x 0.5)

= 11 +  5.50

= $16.50 per hour

If Diego works 9 hours of overtime in a week, he would earn:

= 9 x 16.50

= $ 148. 50

A company's profit increased linearly from $5 million at the end of year 2 to $17 million at the end of year 6.
(a) Use the two (year, profit) data points (2, 5) and (6, 17) to find the linear relationship y = mx + b between x = year and y = profit.
(b) Find the company's profit at the end of 3 years.
(c) Predict the company's profit at the end of 8 years.

Answers

The linear relationship between x = year and y = profit is: y = 3x - 1.The company's profit at the end of 3 years is $8 million.The company's profit at the end of 8 years is predicted to be $23 million.

Below, you will learn how to solve the problem.

(a) To find the linear relationship y = mx + b between x = year and y = profit, we first need to find the slope (m) and the y-intercept (b).


The slope (m) is the change in y (profit) divided by the change in x (year):
m = (17 - 5)/(6 - 2)

m = 12/4

m = 3


Next, we can use one of the data points (2, 5) and the slope (3) to find the y-intercept (b):
5 = 3(2) + b
b = 5 - 6

b = -1


So the linear relationship between x = year and y = profit is:

y = 3x - 1

(b) To find the company's profit at the end of 3 years, we can plug in x = 3 into the equation:
y = 3(3) - 1

y = 8


So the company's profit at the end of 3 years is $8 million.


(c) To predict the company's profit at the end of 8 years, we can plug in x = 8 into the equation:

y = 3(8) - 1 = 23


So the company's profit at the end of 8 years is predicted to be $23 million.

Answers

Answer:

[tex]y=\frac{6}{5} x+1[/tex]

Step-by-step explanation:

Slope-intercept form is a common way to express a linear function.

Solving For Slope-Intercept

In the question, we are given standard form. In order to find slope-intercept, we need to solve for y. This means we need to use the properties of equality to isolate y from the other values.

First, add 6x to both sides.

5y = 6x + 5

Then, divide both sides by 6.

[tex]y=\frac{6}{5} x+1[/tex]

This gives us the final slope-intercept form of the given equation.

Interpreting the Equation

Slope-intercept form is written in the format of y = mx + b. In this equation, m is the slope and b is the y-intercept. Our equation is [tex]y=\frac{6}{5} x+1[/tex]. So, 6/5 is the slope. This means that the rate of change of the graph is 6 units per 5 units. Additionally, the y-intercept is 1. So, the graph crosses the y-axis at y = 1.

DIC DEEPER Your friend earns 7(1)/(2) dollars each hour. Will she earn enough money to buy a $59 pair of headphones after working 4(3)/(4) hours? If not, how much more money does she need?

Answers

No, she will not earn enough money to buy the $59 pair of headphones after working 4(3)/(4) hours. She needs $23.375 more.

To find out how much money she will earn after working 4(3)/(4) hours, we can multiply her hourly wage by the number of hours she works:

7(1)/(2) dollars/hour × 4(3)/(4) hours

Transform the mixed fractions into improper fractions, then multiply.

15/2 dollars/hr x 19/4 hours = 285/8 = 35.625 dollars

So, she will earn $35.625 after working for 4(3)/(4) hours.

To find out how much more money she needs to buy the $59 pair of headphones, we can subtract the amount she earned from the cost of the headphones:

$59 - $35.625 = $23.375

H0: σA2/σB2 ≤ 1 versus H1: σA2/σB2 > 1 Correct
H0: σA2/σB2 = 1 versus H1: σA2/σB2 ≠ 1
H0: σA2/σB2 ≥ 1 versus H1: σA2/σB2 < 1

Answers

(a) Yes, At α = .025, the sample show that portfolio A has significantly greater variance in rates of return than portfolio B. The correct hypotheses for this problem are H0: σA2/σB2 ≤ 1 versus H1: σA2/σB2 > 1.

The appropriate hypotheses are H0: σA2/σB2 ≤ 1 versus H1: σA2/σB2 > 1.  This is because we are testing if portfolio A has significantly greater variance in rates of return than portfolio B.

If the null hypothesis is true, then the ratio of the variances will be less than or equal to 1, meaning that portfolio A does not have greater variance than portfolio B. If the alternative hypothesis is true, then the ratio of the variances will be greater than 1, meaning that portfolio A does have greater variance than portfolio B.

Can y’all please help with part an and part b? I need justification on how you got the answer pleaseee

Answers

Answer:

Part A
Option C

Part B
Option A

Step-by-step explanation:

Part A

The equation for revenue gained for x tickets sold by Alpacas team

is y = 7.5x

This indicates the slope is 7.5 which means for every ticket sold the revenue increases by $7.50

Or in other words, cost of each ticket = $7.50

The revenue - ticket relationship for the Stingrays is given in the form of a graph with a linear equation

The slope of the graph can be found by rise/run where rise

= difference in y values for 2 points on the graph and run

= difference in the corresponding x values

Let's take points (0, 0) and (100, 1500) to find the slope
rise = (1500 - 0)/(10-0) = 1500/10 = 150

run = 10 - 0 = 10

Slope = 150/10 = 15

Equation is y = 15x

So for every ticket sold, the revenue increases by $15

Or in other words, cost of each ticket = $15

Therefore each Stingrays ticket costs 15/7.5 = 2 times each Alpacas ticket

Correct Answer:
Option C

---------------------------------------------------------------------------------------------------------

Part B

For the Geckos swim team we can see that as the number of tickets increases from 6 to 18(difference of 18- 6 = 12), the revenue increases by 180 - 60 = $120

Cost for ticket between 6 and 18 tickets = $120/12 = $10

When tickets sold increases from 18 to 54 (difference of 54 - 18= 36), the revenue increases by $540 - $180 = $360

Therefore the price for each ticket within this range = $360/36 = $10

So the price per ticket is the same regardless of the number of tickets sold

Therefore Gecko's revenue can be modeled as y = 10x

Alpacas charge $7.50 per ticket and Gecko's charge $10 per ticket
So the difference between a Gecko's ticket and an Alpacas ticket

= $10 - $7.50

= $2.50 more than Alpacas

or, alternatively

Alpacas charge $2.50 less than Gecko per ticket

Write the equation of an ellipse with vertices (-5,1) and (-1,1) and co-vertices (-3,2) and (-3,0)

Please explain.

Answers

Check the picture below.

[tex]\textit{ellipse, horizontal major axis} \\\\ \cfrac{(x- h)^2}{ a^2}+\cfrac{(y- k)^2}{ b^2}=1 \qquad \begin{cases} center\ ( h, k)\\ vertices\ ( h\pm a, k) \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \begin{cases} h=-3\\ k=1\\ a=2\\ b=1 \end{cases}\implies \cfrac{(x- (-3))^2}{ 2^2}+\cfrac{(y-1)^2}{ 1^2}=1\implies \cfrac{(x+3)^2}{ 4}+\cfrac{(y-1)^2}{ 1}=1[/tex]

Answer: To find the equation of the ellipse, we need to use the standard form equation of an ellipse:

$\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1$

where (h,k) is the center of the ellipse, a is the distance from the center to the vertices (the major axis), and b is the distance from the center to the co-vertices (the minor axis).

First, let's find the center of the ellipse. The center of the ellipse is the midpoint of the line segment joining the vertices (-5,1) and (-1,1). Using the midpoint formula, we get:

$(h,k) = \left(\frac{-5+(-1)}{2}, 1\right) = (-3,1)$

Now, we need to find the values of a and b. Since the distance between the vertices is 2a, we have:

$2a = |-5-(-1)| = 4$

So, $a = 2$.

Similarly, the distance between the co-vertices is 2b, we have:

$2b = |2-0| = 2$

So, $b = 1$.

Now, we have all the values we need to write the equation of the ellipse:

$\frac{(x+3)^2}{2^2}+\frac{(y-1)^2}{1^2}=1$

Simplifying this equation, we get:

$\frac{(x+3)^2}{4}+(y-1)^2=1$

So, the equation of the ellipse is:

$(x+3)^2/4 + (y-1)^2/1 = 1$

3. For a matrixAof sizem×n, explain why the following statements are logically equivalent: (a) For eachb∈Rm, the matrix equationAx=bhas a solution. (b) Eachb∈Rmis a linear combination of the columns inA(c) The columns ofAspanRm(d) The reduced echelon form ofAhas a pivot in every row.

Answers

All four statements are logically equivalent.

The statements (a), (b), (c), and (d) are all logically equivalent because they all describe the same concept: that the matrix A has a solution for every possible vector b.



Let's start with statement (a): For each b∈Rm, the matrix equation Ax=b has a solution. This means that for any vector b in Rm, there exists a vector x in Rn such that Ax=b.



Now, let's look at statement (b): Each b∈Rm is a linear combination of the columns in A. This means that for any vector b in Rm, we can write b as a linear combination of the columns of A, which is equivalent to saying that Ax=b has a solution.



Statement (c) says that the columns of A span Rm. This means that the columns of A can be combined in a linear combination to produce any vector in Rm, which is equivalent to saying that Ax=b has a solution for any vector b in Rm.



Finally, statement (d) says that the reduced echelon form of A has a pivot in every row. This means that the matrix A is of full rank and that there are no free variables in the equation Ax=b. This implies that there is a unique solution for every vector b in Rm, which is equivalent to saying that Ax=b has a solution for any vector b in Rm.



Therefore, all four statements are logically equivalent because they all describe the same concept: that the matrix A has a solution for every possible vector b.



The solution to this question is to understand that all four statements are logically equivalent because they all describe the same concept: that the matrix A has a solution for every possible vector b.
