The time required for a certain chemical reaction is related to the amount of catalyst present during the reaction.The domain of the relation is the number of grams of catalyst,and the range is the number of seconds required for a fixed amount of the chemical to react.The following relation is the data from several reactions:[(2,180),(2.5,6),(2.7,0.05),(2.9,0.001),(3.0,6),(3.1,6)(3.1,15)(3.2,37),(3.3,176)}.

A. Is the relation a function?

B. If the domain and range were interchanged,would the relation be a function?Explain.

Answers

Answer 1

"Relation is a function if the terms in domain corresponds a unique value in range"

A). Given relation is a function.

B). Interchanged relation will not be a function.

A). From the given ordered pairs, x-coordinate represents the term of Domain and y- coordinate represents the Range.

We find each term of domain is associated with a unique term in range.

Therefore, relation is a one-to-one function.

B). If the terms in range and domain were interchanged, one term 6 of domain relates with two different values of range,

x = 6, y = 2.5

x= 6, y = 3

Since, a term of domain can't have two different values in range,

Therefore, interchanged relation will not be a function.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The cost difference between the new and refurbished computer is $800.00 - $640.00 = $160.00. This means that you would save $160.00 by buying the refurbished computer instead of the new one.

Let's say you work for "x" hours, then your gross pay will be:

A = 10x dollars

Your FICA deduction will be 7.65% of your gross pay:

0.0765 ( 10x ) = 0.765x dollars

Your federal tax withholding will be 12% of your gross pay:

0.12 ( 10x ) = 1.2x dollars

Your state tax withholding will be 8% of your gross pay:

0.08 ( 10x ) = 0.8x dollars

The total amount of taxes that will be deducted from your paycheck is the sum of these three amounts:

0.765x + 1.2x + 0.8x = 2.765x dollars

So your net pay will be:

10x - 2.765x = 7.235x dollars

On simplifying the equation , we get

Now, we can calculate the number of hours you would need to work to pay for the new computer:

800 = 7.235x

x ≈ 110.5 hours

Hence , the number of hours is x = 111 hours
