What is the distance between the points

(-7,1) and (-7,-5) on the coordinate

plane?

Answers

The distance between the points (-7,1) and (-7,-5) on the coordinate plane is 6 units.

The distance formula is a useful tool in many areas of mathematics and science, such as geometry, physics, and engineering. It can be used to find the distance between two points in any number of dimensions, not just two dimensions as in the coordinate plane In addition, the distance formula can also be used to find the length of a line segment in the coordinate plane, which is just the distance between its endpoints. This can be useful in finding the shortest distance between two points, or in finding the length of a path that connects two points.

The distance formula is a mathematical equation used to find the distance between two points in the coordinate plane. It makes use of the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse).

In the coordinate plane, we can represent each point by its coordinates (x1, y1) and (x2, y2). The distance between the points is then given by the equation:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

For the points (-7,1) and (-7,-5), we can plug in the values into the equation:

distance = sqrt((-7-(-7))^2 + (-5-1)^2) = sqrt(0^2 + (-6)^2) = sqrt(36) = 6

So the distance between the points (-7,1) and (-7,-5) on the coordinate plane is 6 units.

Let f (x) = −x2 −5x + 36. What is the value of f (−3)?

Answers

Answer:

Step-by-step explanation:

You just have to substitute -3 into your function.

Therefore: 9 + 15 + 36 = 50

The value of the  f (−3) is 42 after plugging the value of x = -3 in the function f(x) = -x² - 5x + 36.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

f(x) = -x² - 5x + 36

Any function of the form \(\rm f(x) =ax^2+bx+c\)  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.

Plug x = -3 in the above function:

f(-3) = -(-3)² - 5(-3) + 36

f(-3) = -9 + 15 + 36

f(-3) = 42

Thus, the value of the  f (−3) is 42 after plugging the value of x = -3 in the function f(x) = -x² - 5x + 36.

a) Since the triangles are congruent, and ΔABC is congruent to ΔDEF, segments AB and DE have the same value. Therefore, you can use algebra to solve for x when using the knowledge that (12 - 4x) is equal to (15 - 3x).

To solve:

12 - 4x = 15 - 3x

12 = 15 + x

-3 = x

Therefore, x is equal to -3.

b) To find the value of AB, plug in the value of x found in part a).

12 - 4x

12 - 4(-3)

12 - (-12)

12 + 12 = 24

Thus, segment AB is equal to 24.

c) As shown in part b), plug in the value of x found in part a) to find the value of segment DE.

15 - 3x

15 - 3(-3)

15 - (-9)

15 + 9 = 24

Thus, segment DE is also equal to 24.

We can confirm the knowledge of the equal side lengths because the triangle are congruent. This means that all the side lengths in the triangle are the same, which is confirmed when algebraically plugging in the value of x to solve for the values of the segments AB and DE.

Answer:

x = 35

Step-by-step explanation:

\(\frac{2}{5} x + 15 = x - 6\)

First multiply through by 5 to eliminate the fraction

That's

\(5 \times \frac{2}{5} x + 15(5) = 5x - 30 \\ 2x + 75 = 5x - 30\)

Next using the subtraction property subtract 5x from both sides

That's

\(2x - 5x + 75 = 5x - 5x - 30 \\ - 3x + 75 = - 30\)

Next subtract 75 from both sides

\( - 3x + 75 - 75 = - 30 - 75 \\ - 3x = - 105\)

Divide both sides by - 3

\( \frac{ - 3x}{ - 3} = \frac{ - 105}{ - 3} \)

Solve the following linear system of equations by Cramer's rule method;
2x+4y+2z=16
−2x−3y+z=−5
2x+2y−3z=−3
​Rearrange as the form of Ax=B
Find the inverse of the coefficient matrix (A⁻¹); and
Solve the system of equations

Answers

The solution of the given linear system of equations is x = 2, y = 1 and z = 2.

Given that the linear system of equations is

2x + 4y + 2z = 16-2x - 3y + z = -52x + 2y - 3z = -3

To solve the system of equations by Cramer's rule method, arrange them in the form of Ax = B as below:

A = [2, 4, 2; -2, -3, 1; 2, 2, -3], x = [x, y, z] and B = [16, -5, -3]

To find the inverse of the coefficient matrix A⁻¹, first, find the determinant of A as below:

|A| = 2[-3 - 2] - 4[-2 + 2] + 2[-8 + 1] = -12

The determinant is non-zero, hence A is invertible

A⁻¹ = 1/|A| [adj A]

where adj A is the transpose of the cofactor matrix [C] of A:

adj A = [C]T

So, we find [C] by replacing each element of A with its cofactor and taking its transpose matrix as below:

C = [5, 2, 6; 2, -2, 2; -4, -4, -4]

Then [C]T = [5, 2, -4; 2, -2, -4; 6, 2, -4]So, A⁻¹ = 1/|A| [adj A] = 1/(-12) [5, 2, -4; 2, -2, -4; 6, 2, -4] = [-5/6, -1/2, 1/2; -1/6, 1/2, 1/2; 1/2, 1/2, 1/2]

To solve the system of equations, we have x = A⁻¹B as below:

x = [-5/6, -1/2, 1/2; -1/6, 1/2, 1/2; 1/2, 1/2, 1/2][16; -5; -3] = [2; 1; 2]

as the spacing between joists increases, the maximum span for any board size: A. increases only. B. decreases only. C. increases and then decreases. D. decreases and than increases

Answers

As the spacing between joists increases, the maximum span for any board size will B. decrease only. This is because the wider the spacing between joists, the more weight and pressure will be placed on the boards that are spanning the gap between them.

This means that the boards will need to be stronger in order to support the weight without bending or breaking.
If the boards are not strong enough, they may sag or bow under the weight, which can create safety hazards or damage to the structure. Therefore, it is important to use the appropriate board size and spacing between joists for any given application in order to ensure structural integrity and safety.
In summary, increasing the spacing between joists will result in a decrease in the maximum span for any board size, as the boards will need to be stronger in order to support the weight and pressure. It is important to choose the right board size and joist spacing to maintain the structural integrity and safety of the building or structure.

A steel manufacturer wants to produce a container in the shape of a rectangular solid with volume 84m^3 , the manufacturer wants the length of the container to be one meter longer than the width ,and the height to be one meter greater than twice the width. What should the dimensions of the container be ?

Answers

The dimensions of the container should be approximately 3.42 meters (width), 4.42 meters (length), and 7.84 meters (height).

Let's start by assigning variables to the dimensions of the rectangular solid. Let's say the width of the container is w meters.

According to the given information, the length of the container is one meter longer than the width, so the length would be w + 1 meters.

The height of the container is one meter greater than twice the width, so the height would be 2w + 1 meters.

To find the dimensions of the container, we need to consider the volume of the rectangular solid. The volume of a rectangular solid is given by the formula V = length × width × height.

Substituting the values we have:

84 = (w + 1) × w × (2w + 1)

Expanding and simplifying the equation:

\(84 = (2w^2 + 3w + w) \times w\\84 = 2w^3 + 3w^2 + w^2\\84 = 2w^3 + 4w^2\)

Rearranging the equation:

\(2w^3 + 4w^2 - 84 = 0\)

Now we can solve this cubic equation to find the value of w. However, solving a cubic equation analytically can be complex. We can use numerical methods or approximation techniques to find the value of w.

By using numerical methods or a graphing calculator, we find that w is approximately equal to 3.42.

Therefore, the width of the container is approximately 3.42 meters. Using this value, we can calculate the length and height of the container:

Length = width + 1 = 3.42 + 1 = 4.42 meters

Height = 2 × width + 1 = 2 × 3.42 + 1 = 7.84 meters

What is triangle?

Triangle is a three-sided geometric shape which has three angles and three sides. The three sides of a triangle are typically referred to as the base, the height, and the hypotenuse. A triangle can be classified as either right, obtuse, or acute depending on the measure of its angles. Right triangles have one right angle, obtuse triangles have one obtuse angle, and acute triangles have three acute angles.

The coordinate of the image of point K is K’(-2, 1). This means that the x-coordinate of the point is -2 and the y-coordinate of the point is 1. This can be found by multiplying the original x-coordinate of the point K (2) by -1. The y-coordinate of point K remains the same, so the y-coordinate of the image of point K is 1.

how can you tell whether a graph is the graph of a function?

Answers

A graph is the graph of a function if no vertical line intersects the graph at more than one point. This is because a function is a set of ordered pairs (x, y), where each x-value is paired with a unique y-value. If a vertical line intersects the graph at more than one point, then there is more than one y-value for a given x-value, which violates the definition of a function.

To determine whether a graph is the graph of a function, you can use the vertical line test. The vertical line test is a simple test that involves drawing a vertical line through the graph. If the vertical line intersects the graph at more than one point, then the graph does not represent a function.

If, on the other hand, the vertical line intersects the graph at only one point at any given x-value, then the graph represents a function.

In other words, a graph is the graph of a function if no vertical line intersects the graph at more than one point. This is because a function is a set of ordered pairs (x, y), where each x-value is paired with a unique y-value. If a vertical line intersects the graph at more than one point, then there is more than one y-value for a given x-value, which violates the definition of a function.

It's important to note that a graph may only represent a function on a certain domain, and may not represent a function on a different domain. Additionally, some functions may be represented by more than one graph. However, using the vertical line test is a useful and reliable way to determine whether a given graph represents a function or not.

A two-digit number is such that the sum of its digits is 11. When the digits of the number are reversed and the number is subtracted from the original number, the result obtained is 9 Find the original number.​

Answers

By writing and solving a system of equations we will find that the number is 56

So we can write a two-digit number as:

a*10 + b

Where the two digits are a and b.

Here we must have:

a + b = 11

The reversed number is:

b*10 + a

Then we can write the equation:

b*10 + a - a*10 - b = 9

b*9 - a*9 = 9

Then we have a system of two equations:

a + b = 11

b*9 - a*9 = 9

We can divide both sides of the second equation by 9 to get:

b - a = 1

Now we can isolate b to get:

b = 1 + a

Now we can replace this in the other equation.

a + b = a + (1 + a) = 11

2a + 1 = 11

2a = 11 - 1  = 10

a = 10/2 = 5

Now we have the value of a, and we know that:

b = 1 + a = 1 + 5  = 6

An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 grams of an alloy that contains 52% copper with 78 grams of pure copper.

Answers

Answer:

mass of copper in the resulting mixture = 104 grams of pure copper

Percent of the resulting mixture that is copper = 81.25%

Step-by-step explanation:

The complete question is

An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 grams of an alloy that contains 52% copper with 78 grams of pure copper. How many grams of copper are in the resulting mixture? What percent of the resulting mixture is copper?

The original alloy has a mass of 50 grams,

52% of this 50 grams is copper,

mass of copper = 0.52 x 50 = 26 grams

78 grams of pure copper added will bring the mass of copper to..

mass of copper = 26 + 78 = 104 grams of pure copper

After adding 78 grams of copper to the alloy, the resultant mass of the mixture will be = original mass of alloy + mass of the pure copper added

==> 50 + 78 = 128 grams

Percentage of the resulting mixture that is copper = (total mass of copper in the mixture/total mass of mixture x 100%)

==> 104/128 x 100% = 81.25%
