There are two quadratic functions as A. 2b(b - 7) + b = 0 and B. (4a + 2)(2a - 1) + 1 = 0.

The quadratic function is defined as a function containing the highest power of a variable is two.

A. 2b(b - 7) + b = 0 is a quadratic function because it can be simplified to the form of ax² + bx + c = 0 where a, b, and c are constants and x is the variable. In this case, a = 2, b = -13, and c = 0.

B. (4a + 2)(2a - 1) + 1 = 0 is also a quadratic function because it can be simplified to the form of ax² + bx + c = 0. In this case, a = 8, b = -2, and c = 1.

C. 2y + 2(3y - 5) = 0 is not a quadratic function because it can be simplified to the form of mx + b = 0 where m and b are constants and x is the variable.

D. 8 - 5x = 4(3x - 1) is not a quadratic function because it can be simplified to the form of mx + b = 0 where m and b are constants and x is the variable.

Thus, the correct answer would be options A. 2b(b - 7) + b = 0 and B. (4a + 2)(2a - 1) + 1 = 0.

The area of the figure nearest hundredth will be 84.13 square feet.

The quantity area demonstrates the amount of a sector on a planar or hemispherical cup. Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.

The figure is the combination of the rectangle and the semicircle. Then the area of the figure is the addition of the rectangle and the semicircle. Then we have

A = L x W + (π / 8) D²

A = 14 x 5 + (3.14/ 8) (14 - 4 - 4)²

A = 70 + 0.3925 x 36

A = 70 + 14.13

A = 84.13 square feet

The numbers required in the word problem are

Let's call the numbers x and y

From the first equation, we have:

2x + y = 18

From the second equation, we have:

3x - y = 7

Solving simultaneously by substitution method

3x - y = 7

3x = 7 + y

x = (7 + y)/3

substitute this expression for x into the first equation:

2x + y = 18

2((7 + y)/3) + y = 18

14/3 + 3y/3 = 18

14/3 = 18 - 3y/3

14/3 = 18 - y

collecting like terms

y = 18 - 14/3

y = 18 - 4 2/3

y = 13 1/3

substituting to solve for y

x = (7 + y)/3

x = (7 + 13 1/3)/3

x = 10 4/3/3

We write the decimal as a fraction with the decimal value as the numerator and a power of 10 as the denominator, we get 1.1 as a fraction is 11/10.

To convert a decimal to a fraction, we write the decimal as a fraction with the decimal value as the numerator and a power of 10 as the denominator.

For 1.1, we can write it as:

1.1 = 11/10

Therefore, 1.1 as a fraction is 11/10.

Decimal numbers are a way to represent numbers that are not whole numbers or integers. A decimal number consists of two parts: a whole number part and a fractional part, separated by a decimal point. To convert a decimal number to a fraction, we need to write the decimal as a fraction with the decimal value as the numerator and a power of 10 as the denominator.

In the case of 1.1, we can write it as a fraction with a numerator of 11 (the decimal value) and a denominator of 10 (the power of 10 that corresponds to the first decimal place). We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 1 in this case. So the final fraction is 11/10.

Converting decimals to fractions is a useful skill in many areas of math, science, and engineering. It allows us to represent numbers in different ways and to perform calculations that involve fractions and decimals. Knowing how to convert between these two types of numbers can also help us understand the relationship between them and how they are used in real-world applications.

There are 5 cans left over after painting the walls.

Let x represent the maximum number of trims that can be painted

Since each trim requires 1/2 a can, x trims will take x/2 cans

This cannot exceed 5 cans so we get the inequality:
x/2 ≤  5

Multiplying by 2 both sides of inequality:
x  ≤ 10

In words:
Maximum number of trims that can be painted with 5 cans is 10

The number of new phone sold is 1 and the number of old phone sold is 5, if the sales for the day totals $625.

It is given that

A new phone sells for $250

and a used one sells for $75

Let number of new phone is sold = x

and number of old phone is sold = y

Here the total profit for the day is $625

So, 250x + 75y = 625

or 10x + 3y = 25

Now the value of x  and y satisfy the above equation, if we take x = 2 and more than 2, it is clear that it not satisfy the above equation. So we made a conclusion here x must be equal to 1 here.

Generally, A logarithm is a mathematical function that determines the power to which a given number (called the base) must be raised to obtain a certain value. In other words, a logarithm is the inverse operation of exponentiation.

For example, if we take the base 2 and the value 8, the logarithm of 8 to the base 2 (written as log2 8) is 3, because 2 raised to the power of 3 (i.e., 2^3) equals 8.

Logarithms are widely used in many fields of science, engineering, and mathematics, particularly in areas where large numbers or very small numbers are involved. They are also used in data analysis, signal processing, and many other applications.

Answer:

In a box-and-whisker plot, the box represents the middle 50% of the data, with the median value marked by a vertical line inside the box. The "whiskers" extend from the box to the minimum and maximum values in the data set that are not considered outliers. Outliers are marked by individual points outside the whiskers.

To determine the percentage of data values that are greater than a given value, we need to look at the box-and-whisker plot to see where that value falls in the data set. If the value is outside the box, we know that at least 50% of the data values are either greater or less than that value, depending on whether the value is greater or less than the median. If the value is inside the box, we know that exactly 50% of the data values are greater and 50% are less than that value.

In the case of the value 72, we cannot determine the percentage of data values that are greater than it without knowing where it falls in the box-and-whisker plot. If it falls outside the box, we only know that at least 50% of the data values are greater than it. If it falls inside the box, we only know that exactly 50% of the data values are greater than it.

Answer:

Values of x are ±4 and ±5

Step-by-step explanation:

Let y = [tex]x^{2}[/tex]

Which means: [tex]y^{2} = x^{4}[/tex]

Therefore:

A quadratic equation is formed:

[tex]y^{2} - 41y + 400 = 0[/tex]

The above quadratic equation can be simplified either by The Double Bubble Method or using the quadratic formula

Double Bubble Method:

[tex]y^{2} - 41y + 400 = 0[/tex]

The pair of factors of 400 that add together to give 41 are 25 and 16. Use these two factors to rewritre -41y:

[tex]y^{2} - 25y - 16y + 400 = 0[/tex]

Then do Factorization by grouping (i.e group the terms with common factors before factorizing):

[tex]y(y -25) - 16(y - 25) = 0[/tex]

[tex](y - 25)(y - 16) = 0[/tex]

The product of two expressions is zero, which means either of the two expressions is equal to Zero:

Either: [tex]y - 25 = 0[/tex]

Substituting [tex]y = x^{2}[/tex]:

          = [tex]x^{2} - 25 = 0[/tex]

         = [tex]x^{2} = 25[/tex]

         = [tex]\sqrt{x^{2}} = \sqrt{25}[/tex]

         ∴ x = ±5

 Or: [tex]y - 16 = 0[/tex]

Substituting [tex]y = x^{2}[/tex]

     [tex]= x^{2} - 16 = 0[/tex]

     [tex]= x^{2} = 16[/tex]

     [tex]= \sqrt{x^{2}} = \sqrt{16}[/tex]

The Fundamental Counting Principle, choosing from 3 sizes of bottled water and from distilled, filtered, or spring water is 9 ways.

The Basic Counting Principle is a technique used in mathematics, more especially in probability theory and combinatorics, to determine how many combinations of options, items, or outcomes are possible. The Rule of Multiplication, the Product Rule, the Multiplication Rule, and the Basic Counting Rule are some of its alternate names.

It has a connection to the Sum Rule, often known as the Rule of Sum, which is a fundamental counting method used to calculate probabilities.

According to the Basic Counting Principle, if a decision or event has a potential result or set of options, and a different decision or event has b possible outcomes or choices, then the sum of all the unique combinations of outcomes for the two is ab.

Using the fundamental counting principle, if an event occurs in m ways and another event occurs in n ways then the total occurrence is given as (m)(n).
