What is the equation of the function that is graphed as line a?

y = -2 x
y = x + 1
y = x - 1
y = 2 x + 1

Answer:

18.75

Step-by-step explanation:

"Of", in math, typically denotes multiplication, which means we multiply 75% and 25 to find "75% of 25":

75% = 0.75

0.75 * 25 = 18.75

Key expansion is most responsible for this delay.

A block cipher encrypts and decrypts a block of data with an algorithm and symmetric key. In order to expand the keyspace of a block cipher and make it more difficult to break the key through brute force, an initialization vector (IV) must be added to the plaintext that is being used as input. Key Expansion: In the initial stage, it uses just one key, but in later rounds, it expands to multiple keys. Data bytes: Instead of working with bit data, the AES encryption algorithm performs operations on byte data. Consequently, during the encryption process, it treats the size of the 128-bit block as 16 bytes.

The green ornaments that Peter remove from the box will be; 30

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

We are given that box of 120 holiday ornaments, 75% are green and the rest are red.

Therefore, 120 ornaments = 100%

75% are green = 75% of 120

0.75 x 120 = 90

And the rest are red means

120 - 90 = 30

Peter removes green ornaments from the box until only 60% of the ornaments in the box are green that means;

60% of 90

0.60 x 90 = 54

Then the green ornaments that Peter remove from the box will be; 30

0.769 minutes of the ride is spent higher than 17 meters above the ground.

What is the unit conversion in mathematics?

Unit conversion is a multi-step process that includes multiplying or dividing by a numerical factor, determining the appropriate number of significant digits, and rounding.

The given figure is a Ferris wheel we have to find the time spent on the ride higher than 17 m.

It means we have to find time spent riding from A to C through B (i.e., Arc ABC)

From the figure, in ΔAOD, we have

         OA = 12.5 m

         OD = 12.5 - 1 = 11.5 m

Now find 'θ'

           θ = [tex]cos^{-1}(\frac{11.5}{12.5})[/tex]

                = 23.07°

The total angle of arc ABC = 2θ

                                       = 2 * 23.07

                                       = 46.14°

It is given that, 1 full revolution is completed in 6 minutes.

so 46.14° will be completed in = 6/360 * 46.14

                                                  = 0.769 minutes.

Simplified value of given expression is 2x³√10x.

What is simplification?

In arithmetic,  simplification is reducing the expression / fraction problem during a less complicated type.

Main body:

Factor 40 into its prime factors

          40 = 2³ • 5

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent.

Factors which will be extracted are :

          4 = 2²

Factors which will remain inside the root are :

          10 = 2 • 5

To complete this part of the simplification we take the squre root of the factors which are to be extracted. We do this by dividing their exponents by 2 :

          2 = 2

At the end of this step the partly simplified SQRT looks like this:

        2 • sqrt (10x7)

Rules for simplifing variables which may be raised to a power:

  (1) variables with no exponent stay inside the radical

  (2) variables raised to power 1 or (-1) stay inside the radical

  (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:

     (3.1) sqrt(x⁸)=x4

    (3.2) sqrt(x-⁶)=x-3

     (4) variables raised to an odd exponent which is  >2  or  <(-2) , examples:

     (4.1) sqrt(x5)=x²•sqrt(x)

    (4.2) sqrt(x-7)=x³•sqrt(x-1)

Applying these rules to our case we find out that

    SQRT(x7) = x³ • SQRT(x)

 sqrt (40x7) =

       2² x³• sqrt(10x)

Hence the simplification to the value is as 2² x³ • sqrt(10x)

The equation which has exactly one solution is 4 (x + 3) = 7x – 6, and the solution is x = 6.

To solve the equations, we can use Multiplicative Distribution Law.

The first equation, 4 (x + 3) = 7x – 6, has exactly one solution that is x = 6.

4 (x + 3) = 7x – 6

4x + 12 = 7x – 6

4x – 7x = – 6 – 12

– 3x = – 18

x = 6

The second equation, 4 (x + 3) + 8 = 4x + 20, has all real numbers.

4 (x + 3) + 8 = 4x + 20

4x + 12 + 8 = 4x + 20

4x – 4x = 20 – 12 – 8

0 = 20 – 12 – 8

0 = 0

The third equation, 4 (x + 3) + 3x = 7x + 12, has all real numbers.

4 (x + 3) + 3x = 7x + 12

4x + 12 + 3x = 7x + 12

4x + 3x – 7x = 12 – 12

7x – 7x = 0

0 = 0

The last equation, 4 (x + 3) + 6 = 4x + 9, has no solution. It is a wrong equation.

4 (x + 3) + 6 = 4x + 9

4x + 12 + 6 = 4x + 9

4x – 4x = 9 – 12 – 6

0 = - 9

Students are being challenged to present a mathematical concept in multiple ways. There are five different ways to depict thought:

1) Plaything models

2) Still images

3) Printed signs

4) Verbal/written communication

5) actual circumstances or settings

2) Reasoning and Proof:

The habit of reasoning should serve as a backdrop for the development of key mathematical concepts. Asking questions is the key! Why not? Invite students to make conjectures and then to develop, improve, and assess them since mathematics includes discovery. Additionally, let pupils investigate and articulate their own logic. It's frequently beneficial to expand on what kids already know while teaching them.

Students can use technology and manipulatives to solve problems and test their hypotheses at this point.

3) Communication:

Both a method of transmission and a part of what it means to "do" mathematics, communication in mathematics encompasses both. Teachers must create a safe space where students can attempt to share their ideas in the beginning. Since kids don't naturally communicate in math, teachers must be patient while they learn to do so.

4) Problem solving:

Mathematical problem solving is defined as "participating in a task for which the solution approach is not known beforehand. Students must employ previously learned information to create a solution, and by doing so, they obtain new mathematical understandings.

What is proportion?

   In mathematics, proportional means that two quantities or variables are linearly related. When one quantity doubles, the other quantity also doubles. When one of the variables decreases to 1/10th of its previous value, the other also decreases. A ratio is a comparison of two numbers, each representing a part of a whole. Essentially, percentages show that two fractions are equal, even if they are of different magnitudes. For example, 1/2 of 10 marbles has the same ratio as 1/2 of 50 marbles.

Here the relationship between ribbon and bow is proportional. Let us take ribbon as r and bow as b.

=> r ∝b

=> r= kb . Where k is constant.

Now put r=51 and b =17 then,

=> 51=k*17

=> k = 3

then the equation is r = 3b.

Now b=68 then ,

=> r = 3*68

=> r = 204 yard.

Therefore Maila need 204 yard ribbon to make 68 bow.

Step-by-step explanation:

To find the range of lengths for the third side of a triangle when two side lengths are known, first, assign a variable for the length of the third side.

Let x be the length of the unknown side.

Use the Triangle Inequality Theorem to write the three inequalities.

x + 11x > 19

x + 19 > 11

11 + 19 > x

Solve each inequality.

x > 8

x > -8
