The table of linear function shows that f(1) is equal to -3

A linear function is a mathematical function of the form f(x) = mx + b, where m and b are constants and x is the input variable. This function produces a straight line on a graph, with a constant slope (m) and a y-intercept (b) where the line intersects the y-axis.

The slope (m) of a linear function represents the rate of change of the function, or the steepness of the line, while the y-intercept (b) represents the value of the function when x=0.

In the function table given, we can find f(1) when we look at the table.

This shows that f(1) is equal to -3

Answer:

[tex]\frac{6}{15} - \frac{5}{15} = \frac{1}{15}[/tex]

Step-by-step explanation:

The second object is approximately 4.4 * 10^9 times bigger than the first object.

The division of the value of the second scientific notation from the first scientific notation is the precise and accurate way with which we can determine many many times bigger is the second object compared to the first object.

To do so, group coefficients together and exponents together to divide numbers in scientific notation. i.e.

= (3.7/8.5) * ((10^6)/(10^−4))

= 0.43529411 ×  ((10^6)/(10^−4))

Subtract the exponent from the denominator from the exponent of the numerator for the same base 0.43529411 ⋅ 10^(6 −4*−1)

= 0.43529411 × ((10^6+4)

= 0.43529411 × 10^10

= 4.3529411 × 10^9

Step-by-step explanation:

75.00 - 25.00 = 50.00

50.00 / 20.00 = 2.50

So, she needs to mow 2.5 lawns or more to have enough money to buy the skateboard.

The inequality can be expressed as:

20.00 * x >= 50.00

x >= 2.50

So, the inequality "x >= 2.50" can be used to determine the number of lawns she needs to mow to have enough money to buy the skateboard.

Answer: Let's call the number of cookies Trey has "x".

Gerald has 8 less cookies than Trey, so he has x - 8 cookies.

Trey bought five times the number of cookies as Gerald, so he has 5 * (x - 8) = 5x - 40 cookies.

Combining these two equations, we have:

x + (x - 8) = 5x - 40

Simplifying, we get:

2x - 8 = 5x - 40

Solving for x, we find:

3x = 32

And finally, x = 10.

So Trey has 10 cookies and Gerald has 2 cookies.

P(AA) = 0.41

P(PM) = 0.38

P(AA and PM) = 0.05

As you are finding P(AA or PM), you can apply the formula:

P(A U B) = P(A) + P(B) - P( A ∩ B)

U = Union  P( A U B) = P (A or B)

∩ = And

From the formula, you can find out the answer:

P(AA or PM) = P(AA) + P(PM) - P(AA and PM)

                     = 0.41+0.38-0.05

Quadratic X €

Evaluate -20

Answer:

[tex]x=\frac{1}{2} \pm \frac{i\sqrt{5}}{2}[/tex]

Step-by-step explanation:

Lets solve for [tex]x[/tex] in

[tex]-2^2-2x^2+2x+1=0[/tex]

Evaluate [tex]2^2[/tex]

[tex]-4-2x^2+2x+1=0[/tex]

Add [tex]-4[/tex] and [tex]1[/tex].

[tex]-2x^2+2x-3=0[/tex]

Divide both sides of the equation by [tex]-2[/tex].

[tex]x^2-x+\frac{3}{2}=0[/tex]

Now the equation is in standard form.

[tex]ax^2+bx+c=0[/tex]

We can solve this quadratic by completing the square.

Subtract [tex]\frac{3}{2}[/tex] from both sides of the equation.

[tex]x^2-x=-\frac{3}{2}[/tex]

Take one half of the coefficient of [tex]x[/tex] and square it, then add it to both sides.

Add [tex]\frac{1}{4}[/tex] to both sides.

[tex]x^2-x+\frac{1}{4} =-\frac{3}{2}+\frac{1}{4}[/tex]

[tex]x^2-x+\frac{1}{4} =-\frac{5}{4}[/tex]

The left hand side is a perfect trinomial square.

Factor the left hand side by writing it as a square.

[tex]\left(x-\frac{1}{2}\right)^2 =-\frac{5}{4}[/tex]

Take the square root of both sides to eliminate the exponent.

[tex]x-\frac{1}{2} =\pm\sqrt{-\frac{5}{4}}[/tex]

Rewrite [tex]\frac{5}{4}[/tex] as [tex]\left(\frac{i}{2} \right)^2 *5[/tex]

[tex]x-\frac{1}{2} =\pm\sqrt{\left(\frac{i}{2} \right)^2 *5}[/tex]

Pull terms out from under the radical.

[tex]x-\frac{1}{2} =\pm \frac{i}{2} \sqrt{5}[/tex]

Combine [tex]\frac{i}{2}[/tex] and [tex]\sqrt5[/tex].

[tex]x-\frac{1}{2} =\pm \frac{i\sqrt{5}}{2}[/tex]

Add [tex]\frac{1}{2}[/tex] to both sides of the equation.

Based on the given triangle, we can find that:

First, we will focus on the triangle NLP. NLP is a right triangle, then we can use the formula of sinus to find the length of NP, where:

Sin ∠NLP = NP / LP

Sin 35° = NP / 20

0.57 = NP / 20

NP = 11.47

NP ≈ 11

Next, we will focus on triangle GLP. GLP is a right triangle with hypotenuse of 52 and the base of 20. Using the Phytagoras theorem we can try to find the triangle's height.

GL² = GP² + LP²

52² = GP² + 20²

2704 = GP² + 400

GP² = 2304

GP = 48

GP = GN + NP

48 = GN + 11

GN = 37

To find the size of angle ∠GLN, we have to find the size of angle ∠PGN first. We will use the Sines Law:

LP / sin ∠PGN = GL / sin ∠GPN

20 / sin ∠PGN = 52 / 1

sin ∠PGN = 20/52

∠PGN = 22.5°

∠PGN ≈ 23°

∠GLP + ∠GPL + ∠PGN = 180°

∠GLP + 90° + 23° = 180°

∠GLP = 67°

∠GLP = ∠GLN + ∠NLP

67° = ∠GLN + 35°

∠GLN = 32°

The two equations for f(x) are not equal at x = 1 and f(x) is therefore discontinuous at this point

f(x) is discontinuous at x = 1 because when x = 1, the two separate equations for f(x) do not have the same output. For x < 1, [tex]f(x) = x^2 + 4[/tex], so when x = 1, [tex]f(1) = 1^2 + 4 = 5. For x > 1, f(x) = x + 4[/tex] , so when x = 1, f(1) = 1 + 4 = 5. The output of f(1) is different on each side of the discontinuity. This can be seen in the following calculation:

For x < 1,

[tex]f(x) = x^2 + 4f(1) = 1^2 + 4 = 5For x > 1,f(x) = x + 4f(1) = 1 + 4 = 5[/tex]

Since f(1) is 5 for x < 1 and f(1) is also 5 for x > 1, the two equations for f(x) are not equal at x = 1 and f(x) is therefore discontinuous at this point.

The similarity statement compares the two triangles based on their corresponding sides. If two triangles have proportional corresponding sides, then they are similar.

In this case, triangle ABC and triangle GHJ have corresponding sides that are proportional. Specifically, side AB is half the length of side GH, side BC is three-fifths the length of side HJ, and side AC is two-fifths the length of side GJ. Therefore, by the definition of similarity, triangle ABC is similar to triangle GHJ.

As per the given triangles given in the question, the corresponding names are mentioned accordingly in the answer.

A triangle is a basic polygonal geometry with three sides and three interior angles. This is a fundamental geometric shape that is particularly related. Its three vertices are joined together. Depending on their sides and angles, triangles can be classified into a wide range of groups.

In geometry, there are six different kinds of triangles. There are two categories into which they can be divided. The three triangles are categorized as equilateral triangles, isosceles triangles, and scalene triangles based on their sides. Triangles can be classified as acute, obtuse, or right-angled depending on the angle at which they are formed. There are so six different kinds of triangles in geometry.

Step-by-step explanation:

The length and the width of the fencing are 85 feet and 30 feet respectively.

The whole distance that a rectangle's borders, or its sides, the cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the total of its four sides.

Given:

Darrin is hanging 200 feet of Christmas garland on the three sides of fencing that encloses his rectangular front yard.

The length is five feet less than three times the width.

Let w be the width.

Then, 3w - 5 is the length.

So, the perimeter of the rectangular fence = 200 + w.

Now, 2(3w - 5 + w) = 200 + w

6w - 10 + 2w = 200 + w

7w = 210

w = 30

Then length = 85
