Find The Value Of X For The Following

Answers

Answer 1

Answer:

x = -4°

Step-by-step explanation:

We know that,

→ Sum of angles of straight line is 180°.

Now we have to,

→ Find the required value of x.

Forming the equation,

→ (54°) + (7x + 154°) = 180°

Then the value of x will be,

→ 7x + 154° + 54° = 180°

→ 7x + 208° = 180°

→ 7x = 180° - 208°

→ 7x = -28°

→ x = -28° ÷ 7

→ [ x = -4° ]

Hence, the value of x is -4°.

Bailey is making festive cookie bags. She tried to split all her cookies evenly by putting 15 per bag, but the last bag had only 14 cookies. So, she tried putting 10 cookies per bag, but the last bag had only 9. Her mom brought 2 more cookies. Now, Bailey tries 9, then 8, cookies per bag, but she can’t do it. Finally, Bailey puts 7 cookies in each bag evenly! What is the least possible total number of cookies?

Answers

The least possible total number of cookies are 21.

What is total?

A total is a whole or complete amount, and "to total" is to add numbers or to destroy something. In math, you total numbers by adding them: the result is the total.

Given that, Bailey is making festive cookie bags. She tried to split all her cookies evenly by putting 15 per bag, but the last bag had only 14 cookies.

Here, 15+14=29

29 is our first number. Bailey cannot evenly split the cookies into each bag with that amount of cookies, so we must move on to the next number.

Now, 10+9+2=21

21 can be divided 3 times by 7. Now we know the least amount of cookies total, is 21.

Therefore, the total number of cookies are 21.

Answers

The total amount of interest that Alvin paid over the course, guven the value of the student loan and the interest rate is $ 6, 185

How to find the interest paid ?

To find the interest paid, you need to find the total amount that Alvin paid in the 10 years that he was paying.

To do this, you first need to find the monthly payments. This will be an annuity as the amount will be the same throughout the student loan payment period.

The amount would be :

Student loan value = Amount x Present value interest factor of annuity, 120 periods, 4. 4 % / 12

The periods are :

= 10 years x 12 months

= 120 months

The amount is:

26, 000 = Amount x 96.939576551857

Amount = 26, 000 / 96.939576551857

Amount = $ 268. 21

The total paid over the 10 years is :

= 268. 21 x 120 months

= $ 32, 184. 9972

The interest is :

= 32, 184. 9972 - 26, 000 loan amount

Answers

Answer:

Step-by-step explanation:

We can use algebra to solve for the unknown number. Let's call the number "x".

The equation can be written as:

9 + x * (-7) = -19

Expanding the product on the left side:

9 + -7x = -19

Subtracting 9 from both sides:

-7x = -28

Dividing both sides by -7:

x = 4

So the number x is 4.

Note that JKLM has vertices J(1, 3), K(-4,2), L(-1,-5), and M(4,-4). Complete the following to determine if JKLM is a parallelogram.

Answers

Opposite sides JK and ML are equal and parallel (with slopes of -1/5 and 1/5, respectively), and opposite sides KL and MJ are equal and parallel (with slopes of 7/3 or 7). /3) We can conclude that JKLM is a parallelogram

How to determine a parallelogram?

To determine if JKLM is a parallelogram, we need to check if its opposite sides are parallel and equal in length.

First, we can find the lengths of the sides using the distance formula:

JK = [tex]\sqrt{(1 - (-4))^2 + (3 - 2)^2} = \sqrt{25} = 5[/tex]

KL = [tex]\sqrt{(-4 - (-1))^2 + (2 - (-5))^2} = \sqrt{58}[/tex]

LM = [tex]\sqrt{(-1 - 4)^2 + (-5 - (-4))^2} = \sqrt{26}[/tex]

MJ = [tex]\sqrt{(4 - 1)^2 + (-4 - 3)^2} = \sqrt{50}[/tex]

Next, we can find the slopes of the sides using the slope formula:

Slope of JK = (2 - 3)/(-4 - 1) = -1/5

Slope of KL = (-5 - 2)/(-1 - (-4)) = 7/3

Slope of LM = (-4 - (-5))/(4 - (-1)) = 1/5

Slope of MJ = (3 - (-4))/(1 - 4) = 7/3

Since opposite sides, JK and ML have the same length and are parallel (they have slopes of -1/5 and 1/5, respectively), and opposite sides KL and MJ have the same length and are parallel (they have slopes of 7/3 and 7/3, respectively), we can conclude that JKLM is a parallelogram.

Find the standard form of the equation of the parabola with a focus at (3, 0) and a directrix at x = -3. (2 points)

Answers

In reference to the given focus and directrix, the standard form of the equation of the parabola is (x - 3)² = 12y.

Finding the Standard Form of a Parabola with a Given Focus and Directrix

The standard form of the equation of a parabola with a horizontal axis of symmetry and a focus at (p, q) is:

(x - p)² = 4c(y - q)

where, c is the distance from the focus to the vertex.

In this case, the focus is at (3,0), which means that p = 3 and q = 0. The directrix is at x = -3, which means that the vertex is at the midpoint between the focus and the directrix, which is (0,0). The distance from the vertex to the focus (or from the vertex to the directrix) is c = 3.

Substituting these values into the standard form equation, we get:

(x - 3)² = 4(3)(y - 0)

Simplifying, we get:

(x - 3)² = 12y

So the standard form of the equation of the parabola is (x - 3)² = 12y.

Note that the Upper limit and the lower limit of the Proportion Interval are given as follows:

Upper limit-  27%

Lower limit - 19%

What is Proportion Interval?

The proportion interval, also known as the confidence interval, can be calculated using the point estimate of the proportion and the margin of error.

The lower limit of the proportion interval is calculated by subtracting the margin of error from the point estimate, and the upper limit is calculated by adding the margin of error to the point estimate.

Lower limit = point estimate - margin of error

Upper limit = point estimate + margin of error

In this case, the point estimate is 23% and the margin of error is ±4%.

Lower limit = 23% - 4% = 19%

Upper limit = 23% + 4% = 27%

Therefore, the proportion interval is [19%, 27%], which means that we can be 90% confident that the true proportion of the population lies within this range.

11. Equipment for your salon will cost anywhere from $7,000 to $10,000. How much money will you spend over the course of the first year with rent and equipment?

Answers

You have to  spend $26,500 over the course of the first year with rent and equipment.

What is the equipment cost about?

To calculate how much money you will spend over the course of the first year with rent and equipment, you need to add the cost of rent to the cost of equipment.

In a hypothetical scenario, Let's assume that the cost of rent for the first year is $1,500 per month.

To calculate the total cost of rent for the first year, you can multiply the monthly rent by the number of months in a year:

$1,500/month x 12 months = $18,000

So the total cost of rent for the first year is $18,000.

To calculate the total cost of equipment, you can take the average cost of the equipment (i.e., the midpoint of the given range) and assume that you will spend that amount:

($7,000 + $10,000) / 2 = $8,500

So the total cost of equipment is $8,500.

To calculate the total cost of rent and equipment for the first year, you can add the two costs together:

$18,000 + $8,500 = $26,500

Therefore, you will spend $26,500 over the course of the first year with rent and equipment.

A sorting algorithm is defined as an algorithm that sorts the elements of a list. The most commonly used sequences are numerical sequence and lexicographical sequence, ascending or descending.

A sorting algorithm is used to reorder an array or list of elements according to an element comparison operator. Comparison operators are used to define a new order of elements in that data structure. Consider example, The above list of characters is sorted in ascending order by their value. That is, characters with lower values are placed before characters with higher values. It is important in real life because it supports the development of the scientific concept that things can be owned and organized into distinct groups (e.g. creatures, cars, weather types, etc.). We will now discuss some real-world examples of using sorting algorithms.

1) Your phone's contact list is sorted. This means that your data is organized in this way so you can easily access the contacts you want from your phone. That is, "I ordered."

2) Paper sorting : Imagine a teacher sorting students' work alphabetically by student name. This type of operation is similar to the functionality of sorting algorithms such as bucket sort. Sorting is more efficient process.

3) Traffic lights : Traffic lights are a good example of how algorithms are used in the real world around us. Next time you get stuck in a car at a red light, think about the algorithm that traffic lights run." Most traffic lights don't automatically switch between green, yellow, and red. This algorithm is a well-established turn-by-turn algorithm that directs traffic correctly. It's in order (it may not seem that way when you're sitting at a red light).

An angle measures 17.4° more than the measure of its complementary angle. What is the measure of each angle?

Answers

45 and 27.6 degrees are the two complementary angles.

What are the angles' measurements?

The various angles or measurements include:

Measure an acute angle between 0° and 90°.Measure the obtuse angle between 90° and 180°.Right Angle: The measurement is 90 degrees.Straight Angle: The measurement is 180 degrees.Measure the reflex angle from 180° to 360°.Complete or full angle: 360° is the exact measurement.

Angles that are complementary are those whose sum is 90 degrees. If the smaller angle has a measure of x, then the complementary angle's measure is 90 - x.

The issue shows that the greater angle (x + 17.4) is 17.4 degrees larger than the corresponding angle's measurement (90 - x). To find x, we can construct the following equation:

x + 17.4 = 90 - x + 17.4

When we simplify and find x, we obtain:

2x = 55.2

x = 27.6

The greater angle's measure is x + 17.4 = 45 degrees, while the smaller angle's measure is x = 27.6 degrees.

The two complementary angles are 27.6 and 45 degrees as a result.

In other words, it's a factor by which the y-values of a function are multiplied to produce a new, stretched or compressed version of the original graph.

The stretch factor is usually represented by the symbol "k". For example, if the equation of a function is y = f(x), then the equation of its vertically stretched image would be y = k * f(x). A positive value of k stretches the graph upward, while a negative value of k compresses the graph downward. If k > 1, the graph is stretched vertically; if 0 < k < 1, the graph is compressed vertically; if k = 1, the graph remains unchanged.

find the equation of a line passing through two points (1,-1, 2) and (0,2-3).​

Answers

Answer: The equation of the line passing through the points (1, -1, 2) and (0, 2, -3) is:       y = 3x - 4.

Step-by-step explanation:

To find the equation of a line passing through two points, we can use the point-slope form of a line. The point-slope form of a line is given by:

y - y1 = m(x - x1)

where m is the slope of the line, (x1, y1) is a point on the line, and (x, y) are the coordinates of any other point on the line.

Step 1: Find the slope of the line (m)

The slope of the line can be found using the two points:

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

Plug in the values of x1, x2, y1, and y2 from the two given points:

m = (2 - (-1)) / (0 - 1) = 3

Step 2: Write the equation using the point-slope form

Use the point-slope form and the slope from step 1, and one of the given points:

y - (-1) = 3(x - 1)

Step 3: Simplify the equation

y + 1 = 3x - 3

Step 4: Solve for y

y = 3x - 4

So, the equation of the line passing through the points (1, -1, 2) and (0, 2, -3) is y = 3x - 4.

Two right triangles are proportional. The shortest leg of the small triangle is 4 in and the hypotenuse is 12 in. The shortest leg of the large triangle 8 in. Find the length of the hypotenuse of the large triangle.

Answers

If the shortest leg of the small triangle is 4 in and the hypotenuse is 12 in and the shortest leg of the large triangle 8 in, then the length of the hypotenuse of the large triangle is 24 inches.

We know that two triangles are proportional if their corresponding sides are in proportion to each other. That is, the ratio of the lengths of the corresponding sides is the same for both triangles.

Let's denote the length of the hypotenuse of the large triangle by "h". We can set up a proportion using the given information:

shortest leg of small triangle / hypotenuse of small triangle = shortest leg of large triangle / hypotenuse of large triangle

Plugging in the values we get:

4/12 = 8/h

Simplifying the equation we get:

h = (12*8)/4 = 24

To explain the solution, we used the fact that similar triangles have proportional sides. We then used the given information about the lengths of the sides of the small and large triangles to set up a proportion and solve for the unknown length of the hypotenuse of the large triangle.

The key to this problem was recognizing the relationship between similar triangles and using that relationship to set up and solve a proportion.

the values for the first 3 derivatives derivatives of y are 1/2, 5/2, -11/2 respectively

Answers

The given differential equation:

y''' − 2y'' + y' = 2 − 24ex + 40e5x,

y(0) = 1/2, y'(0) = 5/2, y''(0) = −11/2

Therefore, the next solution is 13/2

Differential Equation:

In mathematics, a differential equation is an equation relating one or more unknown functions to their derivatives. In applications, functions usually represent physical quantities, derivatives represent rates of change, and differential equations define the relationship between them. These relationships are common.

Now,

Given differential equation is

y''' - 2y'' +y' = 2- 24eˣ +40e⁵ˣ                 ------------ (1)

Auxiliary equation is m³ - 2m² +2m = 0

Now,

   m(m² - 2m +2) = 0

⇒ m(m-1)² = 0

Therefore, m = 0,1,1

Therefore,

[tex]y_{c} = c_{1}+ c_{2} e^{x} + c_{2}x e^{x}[/tex]

Now, we have to find the particular solution by method of undetermined coefficient.

   [tex]y'_{y} = a + b(x^{2} e^{x} +2xe^{x} ) +5ce^{x}[/tex]

⇒ [tex]y''_{p} = a + bx^{2} e^{x} +2bxe^{x} +5ce^{x}[/tex]

⇒ [tex]y''_{p} = b(x^{2} e^{x} +2xe^{x}) + 2b(ex^{x}+ e^{x} +25ce^{x}[/tex]

⇒ [tex]y'''_{p} = bx^{2} e^{x} +6bxe^{x} +6be^{x} +125ce^{5x}[/tex]

Putting these values in differential equation (1), we get:

y'''(0) = 13/2
