Which of the following BEST defines an output? please help me, I've been stuck on this one for a while!​
NeTakaya

A statement which best defines an output is: B. an output is the result of a relation or the function rule, usually the y-values in a set of ordered pairs or on a table or graph.

<h3>What is a function?</h3>

A function can be defined as a mathematical expression that defines and represents the relationship between two or more variable, which is typically modelled as input (x-values) and output (y-values).

<h3>The types of function.</h3>

In Mathematics, there are different types of functions and these include the following;

  • Periodic function
  • Inverse function
  • Modulus function
  • Signum function
  • Piece-wise defined function

In this context, we can infer and logically deduce that a statement which best defines an output is that it's the result of a relation or the function rule, which usually are the y-values in a set of ordered pairs, on a table or a graph.

Complete Question:

Which of the following best defines an output?

A. An output is the value that determines another based on the relation or the function rule, usually the x-values in a set of ordered pairs or on a table or graph.

B. An output is the result of a relation or the function rule, usually the y-values in a set of ordered pairs or on a table or graph.

C. An output is a special type of relation for which there is a rule that pairs each input with exactly one output.

D. An output is a set of ordered pairs in which no y-value repeats.

he volume of a fish tank is 50 cubic feet. If the density is 0.2 fish over feet cubed, how many fish are in the tank?
V125BC [204]

There are 10 fish in the tank

<em><u>Solution:</u></em>

Given that, volume of a tank is 50 cubic feet

Density is 0.2 fish over feet cubed

<em><u>To find: Number of fish in the tank</u></em>

Number of fish in the tank is found by multiplying the volume of tank and density

<em><u>The formula is given by:</u></em>

\text{Number of fish} = \tex{\text{volume of tank}} \times {\text{density of fish over feet cubed}}

<em><u>Substituting the given values, we get</u></em>

\text{Number of fish} = 50 ft^3 \times \frac{\text{ 0.2 fish}}{ft^3}\\\\ \text{Number of fish} =  50 \times 0.2 \text{ fish }\\\\ \text{Number of fish} = 10 \text{ fish }

Thus there are 10 fish in the tank
