A hardware store rents vacuum cleaners that customers may use for part or all of a day before returning. The store charges a flat fee plus an hourly rate. Write a linear function for the total rental cost, f(x), of a vacuum cleaner after x hours of rental. *
Answer:
f(x) = bx + y
Step-by-step explanation:
Linear functions are very easy as you simply need to multiply the cost per hour (in this scenario) by the total number of hours that the individual is renting the vacuum for. Then you simply add any indpendent value such as the flat fee that the hardware store charges. We can use these values to create the following function.
f(x) = bx + y
where:
b = hourly rate
x = hours of rental
y = flat fee
Below are five questions from a survey of MBA students. Answers were written in the blank at the left of each question. For each question, state the data type (categorical, discrete numerical, or continuous numerical) and measurement level (nominal, ordinal, interval, ratio). Explain your reasoning. If there is doubt, discuss the alternatives. _____ Q11 What is the age of the car you usually drive
Complete question :
Q11. What is the age of the car you usually drive? (years).
Q12.) About how many times in the past year did you attend formal religious services?
Q13.) How often do you read a daily newspaper? (0 = Never, I = Occasionally, 2 – Regularly).
Q14.) Can you conduct simple transactions in a language other than English? (0 = No. 1 = Yes).
Q15. How often do you exercise (aerobics, running, etc)? (0 = Not at All. 1 Sometimes. 2 = Regularly)
Answer:
Continous, ratio
Discrete, Ratio
Categorical, ordinal
Categorical, nominal
Categorical, ordinal
Step-by-step explanation:
Continous variables usually do have an infute number of values inbetween consecutive integers while discrete numeric variables take up whole number values and has a finite number of values. The
Categorical variables are used for Qualitative variables which takes up labels rather than numeric values.
The measurement scales include ;
Ratio scale used for quantitative variables with a true zero value (that is 0, means there is no value for the variable at that point, on a ratio scale with height variable = 0 then there is no height for the measured point). it allows for mathematical calculation of data values as it has a fixed distance between point.
The interval scale is similar ot the ratio aside that it does not have a true zero value, the zero point only serves as a reference point.
The nominal scale, when numbers are used to depict Qualitative variables, such that there is no rank or order in the label. If labels are 0 and 1 for each options, then one label is not superior or inferior to the other
Ordinal variables on the other hand have a particular order or rank for the Qualitative data represented with numerical values :
Here : for a scale of 1 - 5 ; the magnitude increases from 1 through 5
1. continuous numerical, ratio
2. discrete numerical, ratio
3. categorical, ordinal or interval
4. categorical, nominal
5. categorical, ordinal or interval

ANB Leasing is planning to lease an asset costing $210,000. The lease period will be 6 years. At the end of 6 years, the salvage value is estimated to be $30,000. The asset will be depreciated on a straight-line basis of $30,000 per year over the 6-year period. ANB's marginal income tax rate is 40%, but its average tax rate is only 31.5%. Assuming ANB Leasing requires a 12% after-tax rate of return on the lease, determine the required annual beginning of the year lease payments. a. $52,653 b. $45,609 c. $46,120 d. $31,592

Quadrilaterals WXYZ and W"X"Y"Z"are similar. Identify the type of reflection
performed and the scale factor.
A)
To obtain quadrilateral W"X"Y"Z" quadrilateral WXYZ is reflected across
the x-axis and dilated with a scale factor of 3.
B) To obtain quadrilateral W'X'Y"Z" quadrilateral WXYZ is reflected across
the x-axis and dilated with a scale factor of 1/2
c) To obtain quadrilateral W'X'Y"Z" quadrilateral WXYZ is reflected across
the x-axis and dilated with a scale factor of 2.
D) To obtain quadrilateral W X Y Z" quadrilateral WXYZ is reflected across
the x-axis and dilated with a scale factor of 1/3.
Answer:
B) To obtain quadrilateral W'X'Y"Z" quadrilateral WXYZ is reflected across
the x-axis and dilated with a scale factor of 1/2
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.
If a point A(x, y) is reflected across the x axis the new point is at A'(x, -y)
Dilation is the enlargement or reduction in the size of a figure by a scale factor. If a point A(x, y) is dilated by a scale factor of k about the center of origin, the new point is at A'(kx, ky).
The vertex of Quadrilaterals WXYZ is at W(-6, 8), X(-2, 8), Y(-2, 2), Z(-6, 8) while the vertex of Quadrilaterals W"X"Y"Z" is at W"(-3, -4), X"(-2, -4), Y"(-1, -1), Z"(-3, -4)
If quadrilateral WXYZ is reflected across the x-axis, the new coordinates would be at W'(-6, -), X'(-2, -8), Y'(-2, -2), Z'(-6, -8). If the quadrilateral is then dilated with a scale factor of 1/2, the new point is at W"(-3, -4), X"(-2, -4), Y"(-1, -1), Z"(-3, -4)

find the length of side AB and the measure of angle E.
Answer:
c
Step-by-step explanation:
Select the expression equivalent to -81 x + 27.
A -9(9 x - 3)
B -9(-9 x - 3)
C 3+ (-27 x +9)
D -3(-27 x +9)
Answer:
B -9(9x-3)
Step-by-step explanation:
b/c -9(9x-3) means -9×9x-(-3)
= -81x+27
if you say why -(-3) is +27, I will say b/c negative times negetive it give us positive. and if you they why we don't add -81x and 27, I will say b/c they are not like terms.
like terms : are terms with the same variable and same exponent.
example:2x and 3x,5xy and 9yx and etc....

Which of the following equations correctly describes the graphed line?
y = -1/2x - 5
y = -1/2x + 5
y = 1/2x + 5
y = 1/2x - 5
Answer:
Option C i.e. y = 1/2x + 5 is the correct option.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slope b is the y-interceptGiven the points
A(4, 7)
B(-4, 3)
Determining the slope between A and B
(x₁, y₁) = (4, 7) (x₂, y₂) = (-4, 3)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [3 - 7] / [-4 - 4]
= -4 / -8
= 4/8
= 1/2
Thus, the slope of the line = m = 1/2
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 5
Thus, the y-intercept b = 5
now substituting m = 1/2 and b = 5 in the slope-intercept form
y = mx+b
y = 1/2x + 5
Therefore, the equation of line in the graph is:
y = 1/2x + 5
Thus, option C i.e. y = 1/2x + 5 is the correct option.

Step-by-step explanation:
State whether the following mapping represents a function. Then give the domain and range.
Answer:
Please check the explanation.
Step-by-step explanation:
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Let us create the table from the given mapping
x y
2 20
2 40
4 40
3 30
From the table, it is clear that the input x = 2 is repeated twice. In other words, the input x = 2 is duplicated.
i.e. at x = 2, y = 20 and at x = 2, y = 40As we know that we can not have duplicated inputs as there should be only 1 output for each input.
Therefore, the given relation/mapping DOES NOT represent a function.
Determining the domain of a relation:
We know that the domain of the relation is the set of all the x-coordinates of the given points or ordered pairs.
Thus, the domain of the relation in ascending order is:
Domain D = {2, 3, 4}
Please note the duplicated elements in the domain or range of a relation are written only once.Determining the range of a relation:
We know that the range of the relation is the set of all the y-coordinates of the given points or ordered pairs.
Thus, the range of the relation in ascending order is:
Domain D = {20, 30, 40}
