The equation that would give the amount each month, given a certain number of text messages is 27 + 0.43t.

An equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.

Let the number of text messages be represented as t.

Since BobbyLou's cell company charges $27 a month for voice service plus $0.43 for each text message. The amount will be:

= 27 + (0.43 × t)

= 27 + 0.43t

Step-by-step explanation:

Any of the square roots of the number above are between 2.8 repeating and 2.9 repeating.

The equivalent fraction is 40x⁷ of the given expression 8x⁴ × 5x³.

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given in the question as:

8x⁴ × 5x³

We have to determine the equivalent fraction of the given expression.

⇒ 8x⁴ × 5x³

⇒ 8 × 5 × x⁴× x³

Multiply the coefficients in the above expression,

⇒ 40 × x⁴× x³

Add the exponents in the above expression,

Answer:

The percent decrease in the number of people who went to the pool over these four weeks is 15.2%.

The change regarding the people at the swimming pool for the number of weeks will be:

= 1020 - 125 + 145 - 175

= 865

The initial number of people is 1020.

Therefore, the percentage decrease will be:

= Decrease in number / Initial number × 100

= (1020 - 865) / 1020 × 100

= 155/1020 × 100

The will be A'(0, 20),  B'(20, 10) and  '(-10, 0). Transformation is the  of a point from its to a. Types of transformation are reflection, translation, rotation and dilation.

What is transformation?
When a function is transformed, the graph's curve either "moves to the left/right/up/down," "expands or compresses," or "reflects." For instance, by simply moving the graph of the function g(x) = x2 up by 3 units, the graph of the function f(x) = x2 + 3 is obtained. Function transformations are very useful for graphing functions without having to start from scratch because they allow you to move, expand, compress, or reflect the curve. In this article, we will examine the guidelines for function transformations as well as examples of how to transform various function types.

Answer: 5

Step-by-step explanation:

6 liters of brand A fruit punch must be mixed with 9 L of brand b fruit punch.

Let x=liters of Brand A fruit punch to be mixed with 9 liters of Brand B fruit punch.

x + 9 = liters of mixture.

20%(x) + 9*40% = 32%(x+9)

20/100 x + 9*40/100 = 32/100 (x+9)

0.2x + 360/100 = 0.32x + 9*0.32

0.2x + 3.6 = 0.32x + 2.88

0.12x = 3.6 - 2.88

0.12x = 0.72

divide by 0.12 on both sides

x = 0.72/0.12

= 72/100/12/100

= 72/12

Answer:

Step-by-step explanation:

As described in the hint:

The product is:

This is a quadratic expression ax² + bx + c with the leading coefficient of a = - 1, b = 20 and c = 0.

It has a maximum and no minimum value since a < 0.

The x-coordinate of the maximum is the vertex which is x = - b/2a.

The x- coordinate of the vertex is:

The maximum value itself is:

Answer:

10 and 10.

[tex]f(x)=-x^2+20x[/tex]

Maximum value of the function is 100.

Step-by-step explanation:

Two numbers whose sum is a positive integer, and whose product is the maximum possible value have to be two positive integers.

Pairs of positive integers whose sum is 20:

The pair of numbers whose product is the maximum possible value is the pair of numbers that are closest to each other.  

Therefore the pair of numbers is 10 and 10:

[tex]\implies x = 10[/tex]

[tex]\implies 20 - x = 10[/tex]

Form a quadratic function by multiplying:

[tex]\implies f(x)=x(20-x)[/tex]

[tex]\implies f(x)=20x-x^2[/tex]

[tex]\implies f(x)=-x^2+20x[/tex]

The maximum value of the function is the y-value of its vertex.

[tex]\boxed{\begin{minipage}{5.6 cm}\underline{Vertex form of a quadratic equation}\\\\$y=a(x-h)^2+k$\\\\where:\\ \phantom{ww}$\bullet$ $(h,k)$ is the vertex. \\ \phantom{ww}$\bullet$ $a$ is some constant.\\\end{minipage}}[/tex]

To convert the function to vertex form, complete the square.

Factor out negative 1:

[tex]\implies f(x)=-(x^2-20x)[/tex]

Add and subtract the square of half the coefficient of the term in x:

[tex]\implies f(x)=-\left(x^2-20x+\left(\dfrac{-20}{2}\right)^2-\left(\dfrac{-20}{2}\right)^2\right)[/tex]

[tex]\implies f(x)=-(x^2-20x+100-100)[/tex]

[tex]\implies f(x)=-(x^2-20x+100)+100[/tex]

Factor the perfect square trinomial:

[tex]\implies f(x)=-(x-10)^2+100[/tex]

Therefore, the vertex of the function is (10, 100), and so the maximum value of the function is 100.

Quotient is 2x³ +x² -4x+3 for (2x⁴ – 3x³ – 6x² + 11x + 8) ÷ (x – 2)

A division is a process of splitting a specific amount into equal parts.

(2x⁴ – 3x³ – 6x² + 11x + 8) ÷ (x – 2)

Let f(x)=2x⁴ – 3x³ – 6x² + 11x + 8

and g(x)=x-2

We need to divide the f(x) by g(x),

f(x)=g(x)× (2x³ +x² -4x+3)+16

If we equate the above equation with division algorithm which says,

a=bq+r

f(x)=g(x)q(x)+r(x)

so quotient is 2x³ +x² -4x+3

The number of integers between 1 and 2022 inclusive that are multiples of 11 but not multiples of 3, using arithmetic sequences, is of:

122.

An arithmetic sequence is a sequence of values in which the difference between consecutive terms is constant and is called common difference d.

The nth term of an arithmetic sequence is given by the rule presented as follows:

[tex]a_n = a_1 + (n - 1)d[/tex]

In which [tex]a_1[/tex] is the first term of the arithmetic sequence.

The sequence composed by the integer multiples of 11 between 1 and 2022 are given as follows:

(11, 22, ..., 2013)

The first term and the common ratio of the sequence are given as follows:

[tex]a_1 = 11, d = 11[/tex]

The number of terms is obtained as follows:

2013 = 11 + 11(n - 1)

11n = 2013

n = 2013/11

n = 183.

The sequence composed by terms that are multiples of 11 and of 3 is given by:

(33, 66, ..., 2013).

The first term and the common ratio of the sequence are given as follows:

[tex]a_1 = 33, d = 33[/tex]

The number of terms is obtained as follows:

2013 = 33 + 33(n - 1)

33n = 2013

n = 2013/33

n = 61.

Hence the number of integers that are multiples of 11 but not 3 is given by:

183 - 61 = 122.

The value of m in the angle (6m - 12)° is m = 17 , the correct option is (b) .

In the question ,

it is given that ,

the triangle WZY is cut by the bisector ZX ,

and also given that ZW and ZY are congruent ,

that means ZW = ZY

Based on the characteristics of the triangle given ,

we can conclude that triangle WYZ is an isosceles triangle ,

that means , triangle WXZ = triangle YXZ

So ,  ∠YXZ = ∠WXZ = 90°

given that ∠YXZ = (6m - 12)°

So , (6m - 12)° = 90°

6m - 12 = 90

6m = 90 + 12

6m = 102

m = 102/6

m = 17

Therefore , the value of m in the angle (6m - 12)° is m = 17 .

The given question is incomplete , the complete question is

What Is Quartile Formula?

To divide a set of observations into four equal pieces, use the quartile formula. The median and the first term are where the first quartile is located. The median represents the middle quartile. The third quartile represents the midway value that falls between the median and the last term.

Given data set:

19, 39, 9, 33, 15, 16, 2, 33, 16
