Then graph the function and its inverse. g(x) = 3+x
Part 1: Operations of Functions
1. Given f(x) = x² + 7x + 12 and g(x) = x² - 9, we can perform the operations as follows:
(a) (f + g)(x):
(f + g)(x) = f(x) + g(x)
= (x² + 7x + 12) + (x² - 9)
= 2x² + 7x + 3
(b) (f - g)(x):
(f - g)(x) = f(x) - g(x)
= (x² + 7x + 12) - (x² - 9)
= 16x + 21
(c) (-9)(x):
(-9)(x) = -9x
(d) ((x):
((x) is not specified. Please provide the correct function to perform the operation.
2. Given f(x) = 2x + 1 and g(x) = x - 3, we can perform the operations as follows:
(a) (f + g)(x):
(f + g)(x) = f(x) + g(x)
= (2x + 1) + (x - 3)
= 3x - 2
(b) (f - g)(x):
(f - g)(x) = f(x) - g(x)
= (2x + 1) - (x - 3)
= x + 4
(c) (f * g)(x):
(f * g)(x) is not specified. Please provide the correct operation to perform.
(d) ()(x) is not specified. Please provide the correct function to perform the operation.
Part 2: Compositions of Functions
3. Given f(x) = x², g(x) = 5x, and h(x) = x + 4, we can find the value of f[h(-9)] as follows:
f[h(-9)] = f(-9 + 4) = f(-5) = (-5)² = 25
4. Given f(x) = x², g(x) = 5x, and h(x) = x + 4, we can find the value of h∘f(4) as follows:
h∘f(4) = h(f(4)) = h(4²) = h(16) = 16 + 4 = 20
5. Given f(x) = x², g(x) = 5x, and h(x) = x + 4, we can find the value of g[h(-2)] as follows:
g[h(-2)] = g(-2 + 4) = g(2) = 5(2) = 10
6. The formula f = converts inches n to feet f, and m = 5280 converts feet to miles m. The composition of functions that converts inches to miles can be written as m∘f, where m is applied first and then f.
m∘f(n) = m(f(n)) = m(n/12) = n/(12*5280)
Part 3: Inverses of Functions
7. Given f = {(-4,-5), (0,3), (1,6)} and g = {(6,1), (-5,0), (3,-4)}, we can find fg and g∘f, if they exist.
(a) fg:
To find fg, we need to perform the composition of functions fg(x) = f(g(x)).
fg(x) = f(g(x)) = f(1
) = 6
(b) g∘f:
To find g∘f, we need to perform the composition of functions g∘f(x) = g(f(x)).
g∘f(x) = g(f(x)) = g(x²) is not defined since there is no mapping for x² in g.
8. Given g(x) = x + 6 and h(x) = 3x², we can find [gh](x) and [hg](x), if they exist.
(a) [gh](x):
To find [gh](x), we need to perform the composition of functions [gh](x) = g(h(x)).
[gh](x) = g(h(x)) = g(3x²) = 3x² + 6
(b) [hg](x):
To find [hg](x), we need to perform the composition of functions [hg](x) = h(g(x)).
[hg](x) = h(g(x)) = h(x + 6) = 3(x + 6)² = 3(x² + 12x + 36) = 3x² + 36x + 108
9. To find the inverse of the relation {(-5,-4), (1,2), (3,4), (7,8)}, we need to swap the x and y values to obtain the inverse relation:
Inverse relation: {(-4,-5), (2,1), (4,3), (8,7)}
10. To find the inverse of the function g(x) = 3 + x, we need to interchange x and y and solve for y:
y = 3 + x
Interchanging x and y:
x = 3 + y
Solving for y:
y = x - 3
The inverse function of g(x) = 3 + x is g^(-1)(x) = x - 3.
Graphically, the function g(x) = 3 + x and its inverse g^(-1)(x) = x - 3 can be represented by plotting the points and reflecting them across the line y = x.

The denominator in the earnings per share formula is? a.preferred dividends. b.net income. c.number of preferred shared outstanding. d.number of common shares outstanding.
The denominator in the earnings per share formula is number of common shares outstanding.
What is the denominator used in the computation of earnings per share?
The weighted average of the outstanding shares of common stock serves as the numerator of the earnings per share. The "per share" part necessitates further computation when the number of common shares changes in the middle of the year. The weighting of the per share part depends on how long each share number has been in circulation.How are basic earnings per share determined?
Basic EPS is calculated by dividing net income by the weighted average of the common shares outstanding for the relevant period. Preferred dividends should be removed from the net income because they are not available to common stockholders. Net income can also be broken down into "continuing operations" P&L and "total P&L".Learn more about Basic EPS

a) A system of equations that models this situation and helps Mrs. T to know how much the family is being charged for each individual song and each full album downloaded is:
5x + y = 14.903x + 2y = 21.75.b) From the solution of the simultaneous equations, we can determine that each individual song downloaded costs $1.15 while each full album costs $9.15.
What is a system of equations?A system of equations is two or more equations or simultaneous equations, solved concurrently.
Individual Songs Album Total Costs
Anna's download 5 1 $14.90
Owen's download 3 2 $21.75
Let individual songs = x
Let Album = y
Equations:5x + y = 14.90... Equation 1
3x + 2y = 21.75... Equation 2
Multiply Equation 1 by 2:
10x + 2y = 29.80... Equation 3
Subtract Equation 2 from Equation 3:
10x + 2y = 29.80
-
3x + 2y = 21.75
7x = 8.05
x = 1.15
= $1.15
From Equation 1, substitute x = 1.15 to get y:
5x + y = 14.90
5(1.15) + y = 14.90
5.75 + y = 14.90
y = 9.15
y = $9.15
Check Equation 2:
3x + 2y = 21.75
3(1.15) + 2(9.15) = 21.75
3.45 + 18.3 = 21.75

A group of 4 friends went to lunch and spent a total of $40, which included the $34 food bill and the tip. They decided to split the bill and tip evenly among themselves. One of the friends used the equation One-fourth (t 34) = StartFraction 40 over 4 EndFraction to represent the situation, where t represents the total amount of the tip. Which describes the amount each friend paid for the food and for the tip? Each friend paid $8. 50 for the food and $1. 50 for the tip. Each friend paid $10. 00 for the food and $6. 00 for the tip. Each friend paid $8. 50 for the food and $6. 00 for the tip. Each friend paid $10. 00 for the food and $1. 50 for the tip.
The amount each friend paid for food is $8. 50 for the food and $1. 50 for the tip.
What is division?The division is one of the most basic mathematical operators. It is used when a number is to be distributed equally in n number of parts.
As it is given that the total of 4 friends went to the lunch, the total amount paid by them is $40, but the food bill was just $34, therefore, the rest of the amount was paid in the tip. If we calculate the tip,
Tip = Total spent - Food bill
Tip = $40 - $34
Tip = $6
Now, as it is that the total amount spend by all on the food is $34, and it is to be divided among the four friends, therefore, the amount paid by each of the friends is,
\(\text{Total amount to be paid by each friend}=\dfrac{\text{Total amount spent by all on food}}{\text{Number of friends}}\\\\\text{Total amount to be paid by each friend}=\dfrac{\$34}{4}\\\\\text{Total amount to be paid by each friend}=\$8.5\)
Further, the total amount tip by all is $6, and it is to be divided among the four friends, therefore, the amount paid by each of the friends is,
\(\text{Total amount to be paid by each friend}=\dfrac{\text{Total Tip}}{\text{Number of friends}}\\\\\text{Total amount to be paid by each friend}=\dfrac{\$6}{4}\\\\\text{Total amount to be paid by each friend}=\$1.5\)
Hence, the amount each friend paid for food is $8. 50 for the food and $1.50 for the tip.

Mathematics was used in many ways to build the pyramids. The Egyptians used mathematics to calculate the size and shape of the pyramids, to determine the angle of the sides, and to ensure that the pyramids were aligned with the stars.
The pyramids are some of the most impressive feats of engineering in the world. They are massive structures that were built with incredible precision.
The Egyptians used a variety of mathematical techniques to build the pyramids, including:
Geometry: The Egyptians used geometry to calculate the size and shape of the pyramids. They used the Pythagorean theorem to determine the length of the diagonal sides of the pyramids, and they used trigonometry to calculate the angle of the sides.Algebra: The Egyptians used algebra to solve for unknown quantities. For example, they used algebra to solve for the volume of the pyramids.Astronomy: The Egyptians used astronomy to align the pyramids with the stars. They believed that the pyramids were a way to connect with the gods, and they wanted to ensure that the pyramids were aligned with the stars so that the gods would be able to find them.The Egyptians were also very skilled in practical mathematics. They used mathematics to measure distances, to calculate the amount of materials needed to build the pyramids, and to manage the workforce.
The use of mathematics in the construction of the pyramids is a testament to the ingenuity and skill of the ancient Egyptians. The pyramids are a lasting legacy of the Egyptians' mastery of mathematics.
Here are some additional details about how mathematics was used to build the pyramids:
The Egyptians used a unit of measurement called the cubit to measure the size of the pyramids. A cubit is the length from the elbow to the tip of the middle finger, and it is approximately 52.5 centimeters long.The Egyptians used a technique called the seked to determine the angle of the sides of the pyramids. The seked is the rise over run, and it is a measure of the slope of the pyramid.The Egyptians used a star called Alpha Draconis to align the pyramids with the stars. Alpha Draconis is a star that is located in the constellation Draco, and it is one of the brightest stars in the night sky.The use of mathematics in the construction of the pyramids is a remarkable achievement.

find the missing coordinates such that the three vectors form an orthonormal basis for : 0.6 -0.8 , 1 , 0.6 .
The three vectors that form an orthonormal basis for R3 are:
u = (0.6, -0.8, 0)
v = (1, 0, 0)
w = (0, 0, 0.6)
To find the missing coordinates such that the three vectors form an orthonormal basis for R3, we need to use the concept of coordinates, vectors, and orthonormality.
First, let's define the three vectors as u = (0.6, -0.8, 0), v = (1, 0, 0), and w = (0, 0, 0.6).
To form an orthonormal basis for R3, the three vectors need to be orthogonal to each other and have a magnitude of 1.
Orthogonality means that the dot product of any two vectors is 0. So we need to find the missing coordinates of w such that:
u • v = 0
u • w = 0
v • w = 0
Since u and v are already orthogonal to each other, we only need to find the missing coordinates of w such that it is orthogonal to both u and v.
Let's start with u • w = 0:
0.6 * 0 + (-0.8) * 0 + 0 * 0.6 = 0
This equation is already satisfied, so we don't need to find any missing coordinates for w in relation to u.
Now let's look at v • w = 0:
1 * 0 + 0 * 0 + 0 * 0.6 = 0
Again, this equation is already satisfied, so we don't need to find any missing coordinates for w in relation to v.
Since both equations are satisfied, the missing coordinates of w are (0, 0).
Therefore, the three vectors that form an orthonormal basis for R3 are:
u = (0.6, -0.8, 0)
v = (1, 0, 0)
w = (0, 0, 0.6)

Answer:
y = 8.7
Step-by-step explanation:
Assuming we can use decimal places, y is equal to 8.7.
In programming, += is often used as a substitute for y = y + x (example)
Therefore, y = y + 3.7, and since y = 5, y = 5 + 3.7, y = 8.7
Distance Conversions The United States, Liberia, and Myanmar are the only three countries that have not adopted the metric system as its primary system of measurement. There have been reports and legislation calling for a conversion to the metric system since the 1960s. The U.S. Department of Commerce's National Institute of Standards and Technology wrote that "industrial and commercial productivity, mathematics and science education, and the competitiveness of American products and services in world markets, will be enhanced by completing the change to the metric system of units" (1997, 2). From a student's perspective, it would be better if the U.S. converted to the metric system. Because scientists globally use the metric system, most of U.S. scientists do, as well. Until the U.S. "metrifies", students in the United States will need to continue to use and understand both measurement systems. 6. Refer to Appendix 2.1.
