Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Question

Chapter 3.2, Problem 44E

(a)

To determine

To calculate: To find if the table represents a linear or non-linear function

(a)

Expert Solution

Answer to Problem 44E

Thetable represents a non-linear function

Explanation of Solution

Given: Table showing the distance car B is from rental store

Time (hours),t	Distance (miles), d
1	60
2	180
3	310

Formula Used:

Linear functions are polynomials with degree of 1 and have constant slopes. Graph of linear function is a straight line

Non-linear functions are polynomials with degree of more than 1 and have a slope that varies between points. Graph of non-linear function is a curved line

Calculation:

Given table showing the distance car B is from rental store

Time (hours), t	Distance (miles), d
1	60
2	180
3	310

Slope of function is calculated as

m1=180−602−1=1201=120

m2=310−180302=1301=130

Since slopes are different, thus table represents a non-linear function

Conclusion:

Hence, table represents a non-linear function

(a)

To determine

To calculate: To find if given claim is true

(a)

Expert Solution

Answer to Problem 44E

Theclaim is correct

Explanation of Solution

Given: Given the linear function d=50t represents the distance d (in miles) Car A is from a car rental store after t hour

Formula Used:

Linear functions are polynomials with degree of 1 and have constant slopes. Graph of linear function is a straight line

Non-linear functions are polynomials with degree of more than 1 and have a slope that varies between points. Graph of non-linear function is a curved line

Calculation:

Given the linear function d=50t represents the distance d (in miles) Car A is from a car rental store after t hours

Time (hours), t	Distance (miles), d
1	60
2	180
3	310

Claim is “Car B is moving at a faster rate”

Rate of car A is calculated from equation d=50t

Rate=50

Rate of car B is more than rate of car A

Conclusion:

Hence, yes, claim is correct
