The value of the functions 2f + 4g is {(-2,4), (0,6), (2,10), (-2,6), (-8,4), (4,20), (-4,12), (12,0)} and the value of 2g/h is (1,2.5)

In particular, a function maps each element of a set (called the domain) to a unique element of another set (called the range). In this context, we'll look at two functions, f and g, and explore how we can perform arithmetic operations with them.

We can think of these pairs as points on a Cartesian plane, where the x-coordinate represents the input and the y-coordinate represents the output.

Now, let's move on to the arithmetic operations with functions. The first operation we're asked to perform is 2f + 4g. To do this, we need to apply the following steps:

Multiply each ordered pair in f by 2, and multiply each ordered pair in g by 4. This means that the inputs stay the same, but the outputs are multiplied by their respective constants.

Simplify the resulting set by removing any duplicate ordered pairs.

Let's work through this process step by step for our given functions:

Multiplying f by 2 gives us: {(-2,4), (0,6), (2,10), (-2,6)}

Multiplying g by 4 gives us: {(-8,4), (0,12), (4,20), (-4,12), (12,0)}

Taking the union of these sets gives us: {(-2,4), (0,6), (2,10), (-2,6), (-8,4), (4,20), (-4,12), (12,0)}

Simplifying this set by removing duplicates gives us: {(-2,4), (0,6), (2,10), (-2,6), (-8,4), (4,20), (-4,12), (12,0)}

So, 2f + 4g is the function represented by the set {(-2,4), (0,6), (2,10), (-2,6), (-8,4), (4,20), (-4,12), (12,0)}.

For the ordered pair (1,5) in g, the corresponding ordered pair in h is (5,4). So, we can compute 2g(1)/h(5) as follows:

2g(1) = 2 * 5 = 10

h(5) = 4

2g(1)/h(5) = 10/4 = 2.5

Therefore, the ordered pair (1,2.5) is in the result set.

The total number of students in Mrs. Cunningham's class is 30.

From the question we know that the ratio of boys to girls in Mrs. Cunningham's class is 2 to 3 so we can write

no.of boys: no.of girls = 2:3

The total number of girls in the class is given as 18 so with this we can find out the number of boys in the class that is :

no.of boys= (2/3)*no.of girls in class

now after substituting the values in the equation, we get

no. of boys = (2/3) * 18

no.of boys = 12.

So, now we know the number of boys in the class that is 12 and the number of girls in the class is 18.

We can calculate the total number of students in the class which is equal to

= no.of boys + no.of girls.

= 12+18

=30

Therefore, the total number of students in Mrs. Cunningham's class is 30.

The scatterplot with the least squares line provides insights into the relationship between average annual global surface temperature and the years from 2000 to 2015, allowing us to assess trends, strength of correlation, and make predictions within certain limitations.

The scatterplot represents the relationship between the average annual global surface temperature, in degrees Celsius, and the corresponding years from 2000 to 2015. The line drawn on the plot is the least squares line, which is the best fit line that minimizes the overall distance between the observed data points and the line.

The least squares line is determined using a statistical method called linear regression. It calculates the equation of a straight line that represents the trend in the data. This line serves as a mathematical model to estimate the average temperature based on the year.

By analyzing the scatterplot and the least squares line, we can make several observations. Firstly, we can see whether the temperature has been increasing, decreasing, or remaining relatively stable over the given years. If the slope of the line is positive, it indicates a positive correlation, implying that the temperature has been increasing. Conversely, a negative slope suggests a decreasing trend.

Additionally, we can evaluate the strength of the relationship between temperature and time by examining how closely the data points cluster around the line. If the points are closely grouped around the line, it suggests a strong correlation, indicating that the line is a good representation of the data. On the other hand, if the points are more scattered, the correlation may be weaker.

Furthermore, the line can be used to predict the average annual global surface temperature for future years beyond the data range of 2000 to 2015. However, it's important to note that such predictions should be made with caution and considering other factors that may affect global temperatures, such as climate change and natural variability.

The surface area of the closed cylinder is  \(2πrh + 2πr^2\). The lateral surface area of a cylinder can be calculated using the formula 2πrh, where r is the radius and h is the height of the cylinder.

This formula represents the area of the curved surface that wraps around the cylinder.

The surface area of the two circular bases can be calculated using the formula 2πr^2, where r is the radius of the cylinder.

To find the total surface area, we add the lateral surface area and the area of the two bases. Therefore, the formula for the total surface area of a closed cylinder is:

The total surface area is \(\[ A_{\text{total}} = 2 \times 16\pi + 48\pi = 80\pi \text{ square units} \]\).  A closed cylinder is a three-dimensional shape with two circular bases and a curved surface connecting them.

The term "positively-oriented" or "outward-oriented" means that the normal vectors on the surface of the cylinder are pointing away from the center of the cylinder. It has a radius (r) and a finite height (h).

To calculate the surface area of the cylinder, we need to find the area of each circular base and the area of the curved surface.

1. The area of each circular base is given by the formula \(\[ A_{\text{base}} = \pi r^2 \]\). Since there are two bases, the total base area is 2 * A_base.

2. The curved surface area can be calculated using the formula \(\[ A_{\text{curved}} = 2\pi r h \]\). This represents the area of the rectangle that wraps around the cylinder.

3. Finally, we can find the total surface area by adding the base area and the curved surface area: \(\[ A_{\text{total}} = 2 \cdot A_{\text{base}} + A_{\text{curved}} \]\).

For example, let's consider a cylinder with a radius of 4 units and a height of 6 units.

The base area is \(\[ A_{\text{base}} = \pi \times (4^2) = 16\pi \text{ square units} \]\).
The curved surface area is \(\[ A_{\text{curved}} = 2\pi \times 4 \times 6 = 48\pi \text{ square units} \]\) .

To find the dimensions of a rectangle given that its diagonal measures 10cm and one side is 2cm less than the other, we can use a quadratic equation. The dimensions of the rectangle are approximately 6cm and 8cm.

Let's denote the length of one side of the rectangle as x cm. According to the problem, the other side is 2cm less than x, so its length is (x - 2) cm.

We can use the Pythagorean theorem to establish the relationship between the sides and the diagonal of the rectangle. The theorem states that in a right-angled triangle, the square of the hypotenuse (the diagonal in this case) is equal to the sum of the squares of the other two sides.

Applying the Pythagorean theorem to the rectangle, we have:

x^2 + (x - 2)^2 = 10^2

Expanding and simplifying the equation, we get:

x^2 + (x^2 - 4x + 4) = 100

Combining like terms, we have:

2x^2 - 4x - 96 = 0

To solve this quadratic equation, we can factor it or use the quadratic formula. Factoring the equation, we get:

2(x - 6)(x + 8) = 0

Setting each factor equal to zero, we find:

x - 6 = 0 or x + 8 = 0

Solving these equations, we get:

x = 6 or x = -8

Since the dimensions of a rectangle cannot be negative, we discard the solution x = -8. Therefore, the length of one side of the rectangle is approximately 6cm, and the other side (2cm less) is approximately 8cm.
