solve for x and explain

The slope is the steepness of a line on a graph and represents the ratio of the vertical change to the horizontal change, the rate of change refers to the amount of change in one variable corresponding to a unit change in another variable.

The slope of a line is a measure of its steepness or incline. It is calculated by dividing the vertical change (change in y-values) by the horizontal change (change in x-values) between two points on the line. The slope indicates how much the dependent variable (y) changes with respect to a unit change in the independent variable (x). In other words, it represents the ratio of the rise (vertical change) to the run (horizontal change) on the graph.

On the other hand, the rate of change is a broader concept that applies to any relationship between two variables, not just linear relationships. It measures how one variable changes in response to a unit change in another variable. The rate of change can be positive, indicating an increase in one variable for every unit increase in the other variable, or negative, indicating a decrease. It can also vary across different intervals of the relationship, indicating that the relationship is not constant.

In summary, the slope specifically refers to the steepness of a line on a graph and is calculated as the ratio of the vertical change to the horizontal change. The rate of change, on the other hand, is a more general concept that describes how one variable changes in response to a unit change in another variable and can be applied to any type of relationship between variables.

Step-by-step explanation:

Three zeroes of a third-degree polynomial are given, with the graph passing through the point (3,6). To find the equation of this, first, let us set up how a 3rd-degree polynomial factored out should look like:  

y =  a(x+b)(x+c)(x+d).

Since the zeroes of the function are -3, -2, 1, the equation will look like y = a(x+3)(x+2)(x-1). To solve for a, plug-in x = 3 and y = 6 from the point (3,6). After replacing the variable a in the equation with the answer, you will have the solution for the problem.

Third-degree, with zeros of -3,-2, and 1, and passes through the point (3,9) then the polynomial p(x) is (3/20)(x-1)(x+2)(x+3)

Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables

-3 is a root... (x+3) is a factor

-2 is a root... (x+2) is a factor

1 is a root... (x-1) is a factor

p(x) = a(x-1)(x+2)(x+3)

(3, 9) is on graph so p(3)=9

9=a(3-1)(3+2)(3+3)

9=a(2)(5)(6)

9=60a

Divide both sides by 60

a=9/60

a=3/20

p(x) = (3/20)(x-1)(x+2)(x+3)

Hence,  third-degree, with zeros of -3,-2, and 1, and passes through the point (3,9) then the polynomial p(x) is (3/20)(x-1)(x+2)(x+3)

Resources are the means by which an organization achieves its objectives and they are very important in organizational activities. There are various types of resources, such as material resources, human resources, financial resources, technological resources, and information resources, each with its own characteristics. Material resources, for example, are tangible and physical, while human resources are intangible and non-physical. Some of the common characteristics of resources include the fact that they are limited, have alternative uses, and have cost implications.

Resources can be classified in several ways, but the most common classification is as follows: Natural resources (e.g. water, air), Human-made resources (e.g. buildings, machinery), Human resources (e.g. employees, managers), and Financial resources (e.g. money, credit). Natural resources are generally limited and their usage is regulated by laws and regulations. Human-made resources, on the other hand, are created by humans to facilitate their activities. Human resources refer to people who work in an organization and include employees, managers, and executives, while financial resources include money, credit, and other financial assets.

Management process refers to a set of activities that are used to achieve organizational goals and objectives. It is composed of four main functions: planning, organizing, leading, and controlling. Planning involves setting goals, objectives, and strategies to achieve them. Organizing involves allocating resources and developing a structure to achieve goals. Leading involves motivating employees and communicating with them to achieve goals. Controlling involves monitoring and evaluating performance against goals and objectives. In summary, resources are critical to the success of any organization, and they need to be managed effectively to achieve organizational goals and objectives. This involves classifying resources, understanding their characteristics, and applying the management process to ensure that they are used efficiently.

Answer:

18

Step-by-step explanation:

t = Number of trucks counted

c = Number of cars

Ratio of trucks to cars = \(\dfrac{t}{c}=\dfrac{3}{8}\)

Total number of cars and truck = 66

\(t+c=66\)

Divide the left and right side by the number of cars

\(\dfrac{t+c}{c}=\dfrac{66}{c}\\\Rightarrow \dfrac{t}{c}+1=\dfrac{66}{c}\\\Rightarrow \dfrac{3}{8}+1=\dfrac{66}{c}\\\Rightarrow \dfrac{11}{8}=\dfrac{66}{c}\\\Rightarrow c=66\times \dfrac{8}{11}\\\Rightarrow c=48\)

Total number of cars is 48

so

\(t=66-c\\\Rightarrow t=66-48\\\Rightarrow t=18\)

Total number of trucks counted is 18.

Answer: $4.50 for 45min is better.

Step-by-step explanation:

The fee per min for phone charge of $1.40 for 10 min: 1.40/10 = $0.14/min

The fee per min for phone charge of $4.50 for 45 min: 4.50/45 = $0.1/min

$0.14/ min > $0.1/min

4.50 for 45min is better.

The arc length of the sector is 10π inches, and the area of the sector is 60π square inches.

What is the arc length and area of the sector of a circle?

Arc length = \( \frac{ \theta}{ {360}^{o} } \times 2\pi \: r\)

Area of sector = \( \frac{ \theta}{ {360}^{o} } \times \pi \: {r}^{2} \)

Where r is the radius of the circle, angle is the central angle in degrees, and π is the mathematical constant pi (approximately equal to 3.14159).

Given that the angle is 150° and the radius is 12 inches, we can substitute these values into the formulas to get:

Arc length

\(= \frac{150}{360} \times 2π(12) \\ = \frac{5}{12} \times 2π(12) \\ = 10π \: inches\)

Area of sector

\(= \frac{150}{360} \times π(12)^2 \\ = \frac{5}{12} \times π(144) \\ = 60π \: square \: inches\)

Therefore, the arc length of the sector is 10π inches, and the area of the sector is 60π square inches.

The correct option is A. The bar chart provides the least predictive value compared to PERT, ADM, and PDM techniques. It is primarily used for data visualization and comparison, not for forecasting.

The type of chart that provides the least "predictive" value is the Bar chart (A). A bar chart is used to represent categorical data and compare values across different categories. It is not typically used for predictive analysis or forecasting future trends. Instead, it focuses on displaying data in a visual and easy-to-understand format.

On the other hand, PERT (B), ADM (C), and PDM (D) are all project management techniques that are used for planning and scheduling activities in a project. They involve creating network diagrams and calculating critical paths to determine the project's timeline and dependencies. These techniques are more focused on analyzing and predicting the project's timeline and resource requirements, making them more predictive than a bar chart.

In summary, a bar chart provides the least "predictive" value compared to PERT, ADM, and PDM techniques. It is primarily used for data visualization and comparison rather than forecasting future trends.

Using strong induction, we can prove that the square root of -2 is irrational by showing that it cannot be expressed as a fraction of coprime odd integers.

To prove that √-2 is irrational using strong induction, we need to show that for any natural number n, if the square root of -2 can be expressed as a fraction a/b, where a and b are coprime integers, then a and b must be odd.

We can start by using the base case, n = 1. Assume that √-2 can be expressed as a fraction a/b where a and b are coprime integers. Then, we have

√-2 = a/b

Squaring both sides gives

-2 = a^2/b^2

Multiplying both sides by b^2 gives

-2b^2 = a^2

This implies that a^2 is even, and therefore a is also even. We can express a as 2k for some integer k, which means

-2b^2 = (2k)^2

Simplifying, we get

-2b^2 = 4k^2

Dividing both sides by -2 gives

b^2 = -2k^2

This implies that b^2 is even, which means that b is also even. However, this contradicts our assumption that a and b are coprime integers. Therefore, √-2 cannot be expressed as a fraction a/b where a and b are coprime integers.

Now, let's assume that for all n ≤ k, the square root of -2 cannot be expressed as a fraction a/b where a and b are coprime integers with a and b odd. We want to prove that this also holds for n = k+1.

Assume that √-2 can be expressed as a fraction a/b where a and b are coprime integers with a and b odd. Then, we have

√-2 = a/b

Squaring both sides gives

-2 = a^2/b^2

Multiplying both sides by b^2 gives

-2b^2 = a^2

This implies that a^2 is even, and therefore a is also even. We can express a as 2k for some integer k, which means

-2b^2 = (2k)^2

Simplifying, we get

-2b^2 = 4k^2

Dividing both sides by -2 gives

b^2 = -2k^2

This implies that b^2 is even, which means that b is also even. However, this contradicts our assumption that a and b are coprime integers with a and b odd. Therefore, √-2 cannot be expressed as a fraction a/b where a and b are coprime integers with a and b odd.

The equation of the parabola with focus (2,5) and directrix x=18 is (x - 18)² + (y - 5)² = (y - (5 + (18 - 2) / 2))².

A parabola is a conic section, the intersection of a right circular conical surface and a plane parallel to a generating

straight line of that surface.

The focus of a parabola is a fixed point on the interior of a parabola used in the formal definition of the curve.

The directrix is a straight line perpendicular to the axis of symmetry and placed symmetrically with respect to the focus.

The axis of symmetry is the line through the focus and perpendicular to the directrix.

The vertex of a parabola is the point where its axis of symmetry intersects the curve. It is the point where the parabola changes direction or "opens

up" or "opens down.

The directrix is a fixed straight line used in the definition of a

parabola. It is placed such that it is perpendicular to the axis of symmetry and at a distance from the vertex equal to the

distance between the vertex and focus. It is the line that is equidistant to the focus and every point on the curve.Here's

the solution to the given problem:

The distance between the directrix and the focus is equal to p = 16 (since the directrix is x = 18, the parabola opens to the left, so the distance is measured horizontally)

The vertex is (h,k) = ((18+2)/2,5) = (10,5)

Then we can use the following formula: (x - h)² = 4p(y - k)

Substitute the vertex and the value of p. (x - 10)² = 64(y - 5)

Expand and simplify. (x - 10)² + (y - 5)² = 64(y - 5)

The equation of the parabola is (x - 10)² + (y - 5)² = 64(y - 5).

Base Area = 22 cm²

We need to find height of the cylinder

The formula used is: \(Volume\:of\:cylinder=\pi r^2h\)

Where \(Base\: Area = \pi r^2\)

First we need to find radius r

\(Base\: Area = \pi r^2\\22=3.14\: r^2\\r^2=\frac{22}{3.14}\\r^2=7\\Taking\: square\: root\: on\: both\: sides\\\sqrt{r^2}=\sqrt{7}\\r=2.656\)

So, we get radius r = 2.656

Putting values of volume and radius are to find height

\(Volume\:of\:cylinder=\pi r^2h\\198=3.14(2.656)^2h\\h=\frac{198}{22}\\h=9\)
