Quotient = 3x² - 2x + 3

Remainder = 1

Step-by-step explanation:

We have to solve: [tex]\dfrac{3 x^{3} + 4 x^{2} - x + 7}{x + 2}[/tex]

We will use synthetic division to calculate this divisor

First, take the constant term of the divisor with the opposite sign and write it to the left. Write the coefficients of the dividend expression to the right Where there is no coefficient for a specific x term, use 0

Step 1: Write down the first coefficient asis

   |  x³      x²       x¹       x⁰
2  |  3       4        -1        7           ←    Coefficient row
   |
   ---------------------------------

       3                                           ← Result Row

Step 2: Multiply the entry in the left part of the table by the last entry in the result row and add he obtained result to the next coefficient of the dividend, and write down the sum.

    |  x³      x²       x¹       x⁰
-2  |  3       4        -1        7          
     |          -6                                         -6 = -2 x 3
   ---------------------------------

       3     -2                                          -2 = 4 + (-6)

Repeat step 2 until we have finished with all the entries. These are the snapshots of each computation. Current operands are in bold

   |  x³      x²       x¹       x⁰
-2 |  3       4        -1        7          
    |          -6        4                              
   ---------------------------------

       3     -2         3

   |  x³      x²       x¹       x⁰
-2 |  3       4        -1        7          
    |          -6        4      -6                        
   ---------------------------------

       3     -2         3       1

The last entry in the result table shows the remainder of the division

The resultant coefficients are 3, -2, 3, 1

Therefore the answer is
Quotient = 3x² - 2x + 3
Remainder = 1

The value of x is 67°.

To determine the value of x,

Draw a line parallel to lines l and m passing through the vertex at angle x dividing it into two angles a and b.

∠a  = 35°   (Interior Alternate angles are congruent)

∠b + 148°  = 180°  (Co-Interior angles are supplementary)

⇒ ∠b = 32°

∠x  = ∠a + ∠b

⇒ ∠x  = 35° + 32°

⇒ ∠x = 67°

With an income of $57,890, you need to pay $12,735.8 in taxes.

What is mean by proportion?

A proportion is a fraction of a total amount, in which two ratios are set equal to each other.

Given that;

For incomes from $38,701 up to $82,500, you need to pay 22% in taxes.

And, No federal taxes up to $9,525, 12% for income from $9,526 up to $38,700, 22% for income from $38,701 up to $82,500.

Now,

An income of $57,890 is in this range, hence the amount paid is given by;

Amount paid = 57890 x 22%

                    = 57890 x 0.22

                    = $12,735.8.

So, Paid amount for the tax = $12,735.8

Thus, With an income of $57,890, you need to pay $12,735.8 in taxes.

The integer in the solution set of 5/6m - 4 < 1/3m + 5 that would make it false is 20

The set is given as

S:{−18, 2, 15, 20}

The inequality expression is given as

five sixths m minus four is less than one third m plus 5

Rewrite the inequality expression properly

So, we have

5/6m - 4 < 1/3m + 5

Subtract 1/3m from both sides of the inequality expression

So, we have

1/2m - 4 < 5

Add 4 to both sides of the inequality expression

So, we have

1/2m < 9

Divide both sides of the inequality expression hy 1/2

So, we have

m < 18

This means that the integers in the solution set are integers that are less than 18

These integers are −18, 2, 15

Using permutation and combination we can calculate that she can get 63 different types of pizza.

Permutations and combinations are the various ways in which elements from a set may be chosen, typically without replacement, to create subsets. This choice of subsets is known as a permutation when the order of the selection is taken into account, and as a combination when it is not.

The total of the decisions we make given an initial set of n items is known as a combination. Permutation, on the other hand, counts the number of possible arrangements of n separate items. This will help us recall that combinations place more emphasis on choice than on placement, order, or arrangement.

Now Cody can get any two toppings out of the 7.

Number of ways in which Cody can pick 2 toppings out of 7 is given by the use of combination,

7C2 = 21 different ways.

Again the number of ways in which 3 different pizza s can be selected is given by 21 × 3 = 63 ways.

Hence Cody can create 63 different pizzas.

The length of the edge of the box is 6 cm.

Here, we are given that the volume of a box is 216 cm cube.

Here, we assume that the box is a cube and not a cuboid since only then we will be able to find the edge of the box.

The volume of a cube is given by the formula-

Volume = side × side × side

Let the side of the given cube be x.

Then we can form the following equation-

[tex]x^{3}[/tex] = 216

x = (216)^1/3

we can find the 216 is the cube of 6. Thus,

By solving a simple linear equation, we will get that:

36° = m∠AOB

We can write a simple linear equation here, we know that:

m∠AOC = 108°

And we also know that:

m∠AOC = 3*m∠AOB

If we replace the first equation into the second one, then we will have the linear equation:

108° = 3*m∠AOB

And we want to solve this for m∠AOB, to do so, we just need to divid both sides by 3, we will get:

108°/3 = m∠AOB

36° = m∠AOB

Axis of symmetry: x = 3

Min/Max value: f(3) = 1 (Maximum)

y-Intercept: - 8

x-Intercepts: (2, 0), (4, 0)

Domain: All real numbers.

Range: y ≤ 1.

Sketch of the graph: Please see image.

Standard form: f(x) = x² - 6 · x + 8

Rigid transformations: Horizontal translation / Reflection about x-axis / Vertical translation

In this problem we have a quadratic equation in standard form, whose definition is shown below:

f(x) - h = C · (x - h)²        (1)

Where:

Now we proceed to determine each of the required features:

Vertex

The quadratic equation has a vertex at point (3, 1).

Axis of symmetry

The axis of symmetry of the parabola is x = 3.

Min/Max value

For as the vertex constant is a negative number, then the vertex represents a maximum. Then, we evaluate the function at x = 3:

f(3) = 1

y-Intercept

The y-intercept is the value of the quadratic equation evaluated at x = 0.

f(0) = - (0 - 3)² + 1

f(0) = - 9 + 1

f(0) = - 8

x-Intercepts

The x-intercepts are the values of x such that f(x) = 0, all these can be found by using algebra properties:

- (x - 3)² + 1 = 0

- (x² - 6 · x + 9) + 1 = 0

- x² + 6 · x - 9 + 1 = 0

x² - 6 · x + 8 = 0

(x - 2) · (x - 4) = 0

Then, the x-intercepts of the parabola are (2, 0) and (4, 0).

Domain

The domain of all quadratic equations are all real numbers.

Range

Since the vertex constant is negative, the range of the quadratic equation is the subset of all real numbers equal or less than the y-value of the vertex.

Using properties of exponents, the simplified expression for 5³ x 5^(-5) is given by:

A. 1/(5²).

The exponent property applied to multiply the terms with the same base but different exponents is that we keep the bases and then add the exponents.

For this problem, the expression is given as follows:

5³ x 5^(-5)

Hence:

Adding the exponents, we have that:

3 + (- 5) = 3 - 5 = -2.

Hence the simplified expression is:

5³ x 5^(-5) = 5^(-2).

When a number has a negative exponent, we can move it to the denominator, then the exponent becomes positive, hence:

5^(-2) = (1/5)² = 1/5² = 1/25.

Meaning that option A is correct.
