For this case we have:

By definition, a mathematical function is the correspondence or relation f of the elements of a set A with the elements of a set B. A function fulfills the condition of existence (all the elements of A are related to the elements of B) and with the condition of uniqueness (Each element of A is related to a single element of B).

That said, we can conclude that the relationship shown in the table defines a function of the form y = f (x)

By definition, the domain of a function is represented by the input elements of it.

Thus, the domain is given by Domain: (m, n, p, q)

Answer:

Yes, Domain: (m, n, p, q)

Option A

How is 0.025¯¯¯¯ written as a fraction in simplest form?
LUCKY_DIMON [66]

I am not sure if you wrote a repeating decimal with the line next to the 0.025 so comment if you need it. If it wasn't repeating it would be simply 1/40 if there is no repeating and you only want 0.025 is a fraction in simplest form.

What is -5.3125 in The real Number System?
Irina18 [472]

Answer:

It'd be a rational number

Step-by-step explanation:

<em>Real numbers are a set of numbers containing all of the rational numbers and all of the irrational numbers. </em>

Types of numbers <u>in the rational number "section" are decimals, whole, mixed, and fraction numbers whether they are negative or positive they are rational numbers.</u>

Irrational numbers are numbers that cannot be expressed as the ratio of two integers. So they would be square root, pi and more.

Julia rides her horse 18 km with a constant speed of 6km/hr and another 24 km with a constant speed of 12 km/hr. What is her ave
nlexa [21]

Answer:

8.4 km/hr.

Step-by-step explanation:

We have been given that Julia rides her horse 18 km with a constant speed of 6 km/hr.

Let us find the time taken by Julia to cover a distance of 18 km.

\text{Time}=\frac{\text{Distance}}{\text{Speed}}

\text{Time taken to cover 18 km}=\frac{18\text{ km}}{\frac{6\text{km}}{\text{hour}}}

\text{Time taken to cover 18 km}=\frac{18\text{ km}}{6}\times\frac{\text{hour}}{\text{km}}

\text{Time taken to cover 18 km}=\frac{18}{6}\times\text{hour}

\text{Time taken to cover 18 km}=3\text{ hour}

We are also told that she rides another 24 km with a constant speed of 12 km/hr.

Let us find the time taken by Julia to cover a distance of 24 km.

\text{Time taken to cover 24 km}=\frac{24\text{ km}}{\frac{12\text{km}}{\text{hour}}}

\text{Time taken to cover 24 km}=\frac{24\text{ km}}{12}\times\frac{\text{hour}}{\text{km}}

\text{Time taken to cover 24 km}=\frac{24}{12}\times\text{hour}

\text{Time taken to cover 24 km}=2\text{ hour}

Since we know that \text{Average speed}=\frac{\text{Total distance}}{\text{Total time}}.

Upon substituting our values in above formula we will get,

\text{Julia's average speed}=\frac{18\text{ km}+24\text{ km}+}{3\text{ hour}+2\text{ hour}}

\text{Julia's average speed}=\frac{42\text{ km}}{5\text{ hour}}

\text{Julia's average speed}=\frac{8.4\text{ km}}{\text{ hour}}

Therefore, Julia's average speed is 8.4 km per hour.
