Therefore , the solution of the given problem of domain comes out to be The range is {-10, 2, 3, 4, 5, 6, 7} and The domain is {-10, -6, 2, 3, 4, 5, 6, 7, 10}

The domain of a function is the range of possible arguments that it can accept. The cross of the an f-like functional is represented by these numbers (x). The range of potential values to which a function can be applied is known as its domain. The value that the procedure returns after inserting the x value is part of this set. An equation for a function is Y = f, where y and x are predictor variables (x). When a given value of x can produce a single value of y, a parameter is said to be in the scope of a function.

Here,

To determine if the relation is a function, we need to check if each input value (the "x" value) corresponds to exactly one output value (the "y" value).

Looking at the relation {10, 2, -10, 2, 6, 4, 5, 3, -6, 7}, we can see that the input value 2 corresponds to two different output values, 2 and 4. Therefore, the relation is not a function.

To find the domain, we simply list all the input values in the relation. The domain is:

{-10, -6, 2, 3, 4, 5, 6, 7, 10}

To find the range, we list all the output values in the relation.

The range is:

{-10, 2, 3, 4, 5, 6, 7}

Answer:Using sine law, the value of k in the triangle KLM to the nearest tenth is 2.0 inches.

How to use sine law to find sides of a triangle?

Using sine law,

k / sin K = m / sin M

Therefore,

k = ?

K = 21 degrees

M = 180 - 21 - 88 = 71 degrees

m = 5.3 inches

Hence,

k / sin 21 = 5.3 / sin 71°

cross multiply

5.3 sin 21 = k sin 71°

5.3 × 0.35836794954 = 0.94551857559k

1.89935013259 / 0.94551857559 = k

k = 2.00846113168

k = 2.0 inches

Step-by-step explanation:

The domain is all real values and the range is y <= 3

From the question, we have the following parameters that can be used in our computation:

The graph

The domian is the set of the input values

In this case, the graph has no restriction on its input

So, we have

Domain = all set of real values

For the range, we have

Maximum y value = 3

So, we have

Range: y <= 3

The usual sign for greater than and less than is "<", the pointed side is always towards the smaller quantity.

When we compare two quantities in mathematics we us the sign"<".

Now, let us say that there are two quantities a and b, and a is greater than b. So, we can write the relation as, a > b. So, we see that b is less than as a and a is greater than b.

Now, to remember this, the pointed side of the sign will be always towards the quantity that is smaller.

The average rate of change of candle height from time 45 minutes to time 109 minutes is -1 inch per 64 minutes.

The average rate of change is a measure of how quickly one quantity changes relative to another. It is calculated by dividing the difference between two values by the difference in time between those two values. It is a useful metric when trying to understand the speed at which a given quantity is changing over time.

For example, To calculate the average rate of change in the number of students enrolled in a particular school over the course of 5 years. In year 1, the school had 200 students enrolled and in year 5 it had 350 students enrolled. To calculate the average rate of change, one would divide the difference between the two values (150 students) by the difference in time between them (4 years):

Average rate of change = (350-200) / (5-1) = 150 / 4 = 37.5

This means that, on average, the school's enrollment increased by 37.5 students each year.

The table showing the height of a pyramid candle as it burns can be calculated by dividing the change in height (2 inches) by the change in time (64 minutes).

Change in height = 2 inches

Change in time = 64 minutes

Average rate of change = (2 inches) / (64 minutes) = -1 inch per 64 minutes

According to this property, when both sides of an equation are multiplied by the same real number, both sides of the equation always remain the same. The formula for this property can be expressed in real numbers a, b and c. If a × c = b × c.

Property of Equality:

The equivalence property describes the relationship between two equal quantities. If you apply a math operation to one side of the equation, you must also apply it to the other side of the equation to maintain balance.

That is, a property that does not change the truth value of an equation or does not affect the equivalence of two or more quantities is called an equality property. These equality properties help solve various algebraic equations and define equivalence or equilibrium relationships.

Multiplicative Property of Equality:

According to this property, when both sides of an equation are multiplied by the same real number, both sides of the equation always remain the same.

The formula for this property can be expressed as for the real numbers a, b, and c.

If a × b, then, a × c = b × c.

In algebra, the multiplicative property of an equation helps extract unknown terms from an equation. Because multiplication and division are opposites of each other.

To answer this question, we will need to convert the price of the watch in Geneva to pounds and compare it to the price of the watch in Manchester.

First, let's convert the price of the watch in Geneva from CHF to pounds:

193.75 CHF ÷ 1.55 CHF/£ = 125 pounds

Now, we can compare the price of the watch in Geneva to the price of the watch in Manchester:

125 pounds (Geneva) < 145 pounds (Manchester)

Therefore, the watch is cheaper in Geneva.

To find out by how much it is cheaper, we can subtract the price of the watch in Geneva from the price of the watch in Manchester:

145 pounds - 125 pounds = 20 pounds

So, the watch is 20 pounds cheaper in Geneva.

In conclusion, the watch is cheaper in Geneva by 20 pounds.

The car would be worth $9400 in the year 2004.

If the car depreciates by 11% each year, then its value at the end of each year will be 89% of its value at the beginning of the year (100% - 11% = 89%). Therefore, the value of the car after 1 year will be:

$15000 * 0.89 = $13350

The value of the car after 2 years will be:

$13350 * 0.89 = $11881.50

The value of the car after 3 years will be:

$11881.50 * 0.89 = $10576.77

The value of the car after 4 years (in the year 2004) will be:

$10576.77 * 0.89 = $9422.19

As per the conversion, the weight of 40 pounds is equivalent to a weight of 18.14 kilograms.

Converting measurements can sometimes be a tricky task, especially when we need to convert from one unit to another. One common conversion that we often encounter is the conversion of pounds to kilograms. In this guide, we will explain step by step how to convert 40 pounds into kilograms.

First, we need to understand the basic unit of measurement for both pounds and kilograms. Pounds are a unit of measurement commonly used in the United States and the United Kingdom to measure weight. Kilograms, on the other hand, are the standard unit of measurement for weight in the International System of Units (SI).

To convert 40 pounds to kilograms, we need to use the following formula:

1 pound = 0.45359237 kilograms

Using this formula, we can calculate the equivalent weight in kilograms for 40 pounds. We simply multiply 40 by 0.45359237 to get:

40 x 0.45359237 = 18.14374948 kilograms

So, 40 pounds is equivalent to 18.14374948 kilograms (rounded off to the nearest hundredth) we get 18.14 kilograms.

[tex]Graph {y = sqrt(x+1)-3 [-10, 10, -5, 5]}[/tex]

Graph is a diagram that is used to represent data or information. It is a visual representation of data in the form of points, lines, bars, and other shapes. Graphs can be used to show relationships between different quantities, to compare data, and to show changes over time. Graphs are useful for quickly conveying information in an easy-to-understand visual format. They are especially useful for displaying complex data in an intuitive way.

For example, A bar graph can be used to compare the average monthly temperature of five different cities. The x-axis would show the five cities, while the y-axis would show the temperature. Bars would be drawn to represent the temperature of each city. This would make it easy to visually compare the temperatures of the different cities.

The graph of y = √(x+1)-3 is shown above.

To get three points to graph, let's work through the following examples:

When x = 0, y = √(0+1)-3 = 0-3 = -3

When x = 4, y = √(4+1)-3 = 2-3 = -1

When x = 8, y = √(8+1)-3 = 3-3 = 0

Therefore, the three points to graph are (0,-3), (4,-1), and (8, 0).
