Let's do a couple of similar examples with the tan function.
The figure below, shows the graph of a function.
f(x)=
The domain are the possible input while the range are the possible output of a function.
(a) The domain = [-√2, √2], the range = [0, 2]
(b) The domain = [-1, 1], the range = [0, 1]
(c) The domain = [-1, 1], the range = [0, -1]
(d) The domain = [0, 2], the range = [0, 1]
(e) The domain = [-(2 + √2), (√2 - 2)], the range = [0, 2]
Reasons:
The given functions can be expressed by the equation; (-x + 1)·(x + 1) = -x² + 1
Therefore, we have;
(a) y = f(x) + 1 = -x² + 1 + 1 = -x² + 2
The x-intercept of the above function are, x = √2, and x = -√2
Which gives;
The domain = [-√2, √2]
The range = [0, 2]
(b) y = 3·f(x) = 3 × (-x² + 1) = -3·x² + 3
At the x–intercepts, we have;
-3·x² + 3 = 0
x = ±1
The domain = [-1, 1]
The maximum value of y is given at x = 0, therefore;
= -3 × 0² + 3 = 3
The range = [0, 1]
(c) y = -f(x) = -(-x² + 1) = x² - 1
At the x–intercepts, x² - 1 = 0
x = ± 1
The domain = [-1, 1]
The minimum value of y is given at x = 0, which is y = -1
The range = [0, -1]
(d) y = f(x - 1) = -(x - 1)² + 1 = -x² + 2·x
At the x–intercepts, we have; -x² + 2·x = 0, which gives;
(-x + 2)·x = 0
Which gives, x = 0, or x = 2
The domain = [0, 2]
The maximum value of y is given when x = -b/(2·a) = -2/(2×(-1)) = 1
y = f(1) = -1² + 2×1 = 1
Therefore;
The range = [0, 1]
(e) y = f(x + 2) + 1 = (-(x + 2)² + 1) + 1 = -x² - 4·x - 2
At the x–intercepts, we have; -x² - 4·x - 2 = 0, which gives;
x = -(2 + √2) or x = x = √2 - 2
The domain = [-(2 + √2), (√2 - 2)]
The maximum value of y is given when x = -4/(2)) = -2
Which gives;
-(-2)² - 4·(-2) - 2 = 2
The range = [0, 2]

A carpenter is building a rectangular table. He wants the perimeter of the tabletop to be no more than 28 feet. He also wants the length of the tabletop to be greater than or equal to the square of 2 feet less than its width. Create a system of inequalities to model the situation, where x represents the width of the tabletop and y represents the length of the tabletop. Then, use this system of inequalities to determine the viable solutions.
The option is (B) The entire solution region is viable is correct when both the inequalities are solved.
What is an inequality?
In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.
Let's first translate the given information into mathematical inequalities -
The perimeter of the tabletop to be no more than 28 feet -
Perimeter = 2(length + width) ≤ 28
The length of the tabletop to be greater than or equal to the square of 2 feet less than its width -
Length ≥ (Width - 2)²
We can combine these two inequalities to form the system -
2(length + width) ≤ 28
Length ≥ (Width - 2)²
Now, let's solve for y in terms of x (so that we can graph the solution region) -
2(y + x) ≤ 28
y ≥ (x - 2)²
Simplifying the first inequality -
y ≤ -x + 14
Now graph both the inequalities -
The viable solutions are the points that satisfy both inequalities, which lie in the shaded region above.
Therefore, there is no part of the solution region that includes negative length or negative width.

The bricks on the warehouse of the museum are crumbling. The community needs to hire a contractor
to replace the bricks with siding because it is more cost efficient. You have chosen the siding that will
replace the bricks. Each piece of siding is 4 ¾ inches x 24 inches. Estimate the cost to replace the
brick with siding with siding priced at 22.65 a piece.
The Warehouse
sides:
17ft
25ft
33ft
A. Determine the surface area of the warehouse.
B. What is the area of the surfaces that need siding? Justify your reasoning.
C. How many pieces of siding need to be purchased? Justify your reasoning.
D. What is the approximate cost of siding that will be needed to cover the outside of the
warehouse? Justify your reasoning.
Answer:
Step-by-step explanation:
here is a step by step answer:
A. To determine the surface area of the warehouse:
Identify the dimensions of each side of the warehouse. In this case, we know that the sides are 17 ft, 25 ft, and 33 ft in length, and the height is 10 ft.
Calculate the area of each side by multiplying the length and height. For example, the area of the first side is 17 ft x 10 ft = 170 sq ft.
Add up the areas of all the sides to get the total surface area of the warehouse. In this case, the total surface area is 170 + 250 + 330 = 750 sq ft.
B. To determine the area of the surfaces that need siding:
Since all sides of the warehouse need to be covered with siding, the area of the surfaces that need siding is equal to the total surface area of the warehouse. In this case, we calculated the total surface area to be 750 sq ft.
C. To determine how many pieces of siding need to be purchased:
Identify the size of each piece of siding. In this case, we know that each piece of siding is 4 ¾ inches x 24 inches.
Convert the size of each piece of siding to square feet. To do this, we can divide the length and width by 12 to convert to feet, and then multiply the two dimensions to get the area. In this case, 4 ¾ inches is approximately 0.3958 feet, and 24 inches is 2 feet, so the area of each piece of siding is approximately 0.7916 sq ft.
Divide the total surface area of the warehouse by the area of each piece of siding to get the number of pieces needed. In this case, we calculated that the total surface area is 750 sq ft, and each piece of siding covers approximately 0.7916 sq ft. So, the number of pieces needed is 750 sq ft ÷ 0.7916 sq ft/piece = 946.84 pieces. We must round up to the nearest whole number because we can't purchase a fraction of a piece of siding. So, we need to purchase 947 pieces of siding.
D. To determine the approximate cost of siding needed to cover the outside of the warehouse:
Identify the price per piece of siding. In this case, we know that the siding is priced at $22.65 per piece.
Multiply the number of pieces of siding needed by the price per piece to get the total cost of siding. In this case, we calculated that we need 947 pieces of siding, so the total cost of siding is 947 x $22.65 = $21,465.55. So, the approximate cost of siding needed to cover the outside of the warehouse is $21,465.55.

Then f'(a) exists if and only if these one-sided derivatives exist and are equal.(a) Find f' ^- (4) and f' ^+ (4) for the functionf(x)=⎧⎪⎨⎪⎩0 if x⩽05−x if 0
Answer:
Step-by-step explanation:
To find the left-hand derivative of f at x = 4, we need to evaluate:
f′−(4) = limh→0−f(4+h)−f(4)h
Since f(x) = 0 for x ≤ 0 and f(x) = 5 - x for 0 < x < 5, we have:
f(4 + h) = 0 for h < -4
f(4 + h) = 5 - (4 + h) = 1 - h for -4 < h < 1
f(4 + h) = undefined for h > 1
Therefore, we can rewrite the limit as:
f′−(4) = limh→0−f(4+h)−f(4)h = limh→0−(1 - h) - 0h = -1
To find the right-hand derivative of f at x = 4, we need to evaluate:
f′+(4) = limh→0+f(4+h)−f(4)h
Using the same reasoning as before, we can rewrite the limit as:
f′+(4) = limh→0+(5 - (4 + h)) - 0h = -1
Since the left-hand derivative and the right-hand derivative are equal, we can conclude that f'(4) exists and is equal to:
f'(4) = f′−(4) = f′+(4) = -1
Therefore, the derivative of f at x = 4 is -1.
You have a FICO score of 776 so you can borrow money at 4.2% interest. If your score is 495, you will have to pay 8.9% interest. How much less will you pay in simple interest in one year on a loan of $12,984 if you have a higher credit score?
Please show work and explain.
Answer:
$610.25
Step-by-step explanation:
The simple interest at a higher FICO score over the lower FICO score
= 8.9% - 4.2% = 4.7%
4.7% = 4.7/100 = 0.047 in decimal
Therefore at simple interest the amount of money saved for 1 year on a loan of $12,984
= $12,984 x 0.047 = $610.25
Answer:
$611.63
Step-by-step explanation:
To Calculate the amount of interest saved with a higher credit score, we need to find the difference in the amount of interest paid over the course of one year on a loan of $12,984 at each interest rate.
First, we'll calculate the interest paid at 4.2% interest with a FICO score of 776:
Interest rate = 4.2%
Loan amount = $12,984
Simple interest = Interest rate x Loan amount
Simple interest = 4.2% x $12,984
Simple interest = $545.45
Next, we'll calculate the interest paid at 8.9% interest with a FICO score of 495:
Interest rate = 8.9%
Loan amount = $12,984
Simple interest = Interest rate x Loan amount
Simple interest = 8.9% x $12,984
Simple interest = $1,157.08
The difference in interest paid is the amount saved by having the higher credit score:
Interest saved = Interest paid at 8.9% - Interest paid at 4.2%
Interest saved = $1,157.08 - $545.45
Interest saved = $611.63
Therefore, having a higher credit score of 776 would save you $611.63 in simple interest over the course of one year on a loan of $12,984.

2/4 cups pretzels
3/4 cup nuts of your choice
1/2 cup raisins
1/3 cup chocolate chips (optional)
Answer:
[tex]\frac{1}{8}[/tex] cup pretzels, [tex]\frac{3}{16}[/tex] cup nuts of your choice, [tex]\frac{1}{8}[/tex] cup raisins, [tex]\frac{1}{12}[/tex] cup chocolate chips (optional)
Step-by-step explanation:
What is a fraction?A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
If we need to multiply the fractions in the recipe by [tex]\frac{1}{4}[/tex], we just need to multiply the denominator by 4.
[tex]\frac{2}{4}[/tex] cups pretzels becomes [tex]\frac{2}{16}[/tex] or [tex]\frac{1}{8}[/tex].
This is because the denominator (4) is multiplied by 4 to get 16. The numerator doesn't change.
[tex]\frac{3}{4}[/tex] cup nuts becomes [tex]\frac{3}{16}[/tex].
This is because the denominator (4) is multiplied by 4 to get 16. The numerator doesn't change.
[tex]\frac{1}{2}[/tex] cup raisins becomes [tex]\frac{1}{8}[/tex].
This is because the denominator (2) is multiplied by 4 to get 8. The numerator doesn't change.
[tex]\frac{1}{3}[/tex] cup chocolate chips becomes [tex]\frac{1}{12}[/tex].
This is because the denominator (3) is multiplied by 4 to get 12. The numerator doesn't change.
Now, the recipe looks like this:
[tex]\frac{1}{8}[/tex] cup pretzels
[tex]\frac{3}{16}[/tex] cup nuts of your choice
[tex]\frac{1}{8}[/tex] cup raisins

Consider right triangle ABC.
A triangle ABC has right angle at B is shown. Base AB has length labeled 40 units. Height BC has length labeled 9 units, and hypotenuse AC has length 41 units.
Answer:
By using trigonometric relations, we will see that:
AC = 15.6 in
AB = 8.4 in.
How to get the measures of the other two sides of the right triangle?
Here we have the right triangle where:
B = 90°
C = 40°
BC = 10 in.
Notice that is the adjacent cathetus to the angle C, then we can use the two relations:
sin(a) = (adjacent cathetus)/(hypotenuse).
tan(a) = (opposite cathetus)/(adjacent cathetus).
Where:
hypotenuse = AC
opposite cathetus = AB.
Then we will have:
sin(40°) = 10in/AC.
AC = 10in/sin(40°) = 15.6 in
tan(40°) = AB/10in
tan(40°)*10in = AB = 8.4 in.
So we can conclude that for the given right triangle we have:
AC = 15.6 in
AB = 8.4 in.

What is the slope?
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line
Slope PQ 5–0/ 2–6 = 5 /-4
equation of PQ y =-5/4 x +c ;
this passing through 2,5
5 =-5/4*2 +c ; C = 5 -5/2 =5/2
y =-5x/4+5/2 =-5x+10/4 ; 4y =-5x +10 ;
equation of PQ =5x +4y-10 =0 ;
slope of PR : m1 *m2 =-1 ;m2 = -1/ [-5/4 ] = 4/5
equation of PR y = mx +c this passes through [2,5]
5 = 4/5*2 +C so C = 5- 8/5 =17/5
y =4 x /5 +17/5 so coordinates of R = [0, 3.4]
Hence, the coordinates of the point R: (0, 3.4)

In ggplot2, the term mapping refers to the connection between variables and a plotting object like point, line, or other shape.
Yes, in ggplot2, mapping refers to the process of connecting variables in a data set to visual elements of a plot, such as points, lines, or other shapes.
According to given conditions:Yes, in ggplot2, mapping refers to the process of connecting variables in a data set to visual elements of a plot, such as points, lines, or other shapes. This is done by mapping variables to aesthetic properties of the plot, such as the x and y coordinates, the size, color, or shape of the points, or other visual properties that can be customized.
For example, if we have a data set with two variables, x and y, we can create a scatterplot of the data by mapping the x variable to the x-axis and the y variable to the y-axis, using the aes() function in ggplot2. We can also customize the appearance of the points by mapping other variables to the size, color, or shape of the points, as well as adding other elements to the plot, such as a title or legend.
The mapping process is an important part of data visualization in ggplot2, as it allows us to explore the relationship between different variables and to communicate our findings in a clear and effective way. By mapping variables to visual elements of a plot, we can create informative and visually appealing graphics that can help us understand and communicate complex data sets.
What is variable ?In programming, a variable is a named storage location that can hold a value or a reference to a value. Variables are used to store and manipulate data in a program, and they can take on different values at different times during the execution of the program.
In most programming languages, variables are defined by specifying a name and a data type. The data type determines the kind of data that can be stored in the variable, such as numbers, strings, or Boolean values, and also affects the size and behavior of the variable.
Variables can be assigned a value using the assignment operator, which stores the value in the variable's memory location. Once a value has been assigned to a variable, it can be accessed and manipulated using its name.
In addition to simple data types, programming languages also support more complex types of variables, such as arrays, objects, and pointers, which can store collections of values or references to other variables.
Variables are a fundamental concept in programming, and they are used extensively in all kinds of software applications, from simple scripts to complex systems. Understanding how to use variables effectively is an essential skill for any programmer.

A store is offering 20% discounts on new laptops and 10% discounts on new printers when the two are purchased together. The original prices of the two together is at least $1,050. The discounted price exceeds $860. Which system of inequalities can be used to find the possible original prices of a laptop, x, and of a printer, y?
The system of inequalities that can be used to find the possible original prices of a laptop, x, and of a printer, y is: x + y ≥ 1050 and 0.8x + 0.9y > 860
How to determine the system of inequalitiesLet x be the original price of the laptop and y be the original price of the printer.
So, the discounted price of the laptop is 0.8x and the discounted price of the printer is 0.9y
If the two are purchased together, the total discounted price is:
0.8x + 0.9y
This exceeds $860
0.8x + 0.9y > 860
The original prices of the two together is at least $1,050.
This can be written as:
x + y ≥ 1050
So, we have
x + y ≥ 1050 and 0.8x + 0.9y > 860

y=100000(0.25)^8 exponential decay
y=100000(0.25)^8 exponential decay is 1.526.
How to find the exponential decay?The formula represents exponential decay with a decay factor of 0.25 and an initial value of 100,000. To evaluate the formula, you can simply substitute 8 for the variable x (since the formula has y in terms of x) and calculate the result:
y = 100000(0.25)^8
y = 100000(0.00001525878906)
y ≈ 1.526
Therefore, the value of y for x = 8 is approximately 1.526. This means that after 8 units of time, the initial value of 100,000 has decayed to around 1.526.

Identify the solution to the system of linear equations.
y = -3x + 2
y = x - 6
A. (2, -4)
B. (4, -2)
C. (0, 2)
D. (1, -1)
The system of linear equations is solved by finding x = 2 and y = -4, making the solution (2, -4).
To find the solution to the system of linear equations,
find the values of x and y that satisfy both equations simultaneously.
The equations are,
y = -3x + 2
y = x - 6
To find the solution, set the right-hand sides of both equations equal to each other:
-3x + 2 = x - 6
Now, let's solve for x:
-3x - x = -6 - 2
-4x = -8
x = -8 / -4
x = 2
Now that the value of x, we can find y by substituting x back into one of the equations.
Let's use the second equation:
y = 2 - 6
y = -4
Therefore, the solution to the system of linear equations is equal to option A. (2, -4).
