After considering the given data we conclude that the x-coordinate of the inflection points for the function are x = - 2 and x = 2, which is option A.
To evaluate the x-coordinate of the inflection points for the function f(x) = ln(x² + 4) we need to evaluate the second derivative of the function and find for x when the second derivative equals zero.
The first derivative of f(x) is:
f' * (x) = (2x)/(x² + 4)
The second derivative of f(x) is:
f"(x) = 2(x² + 4)-4x² /(x²+4)² = 8 - 2x²/(x²+4)²
To evaluate the inflection points, we need to find the equation f'' (x) = 0 for x:
8 - 2x²/(x²+4)² = 0
After applying simplification this equation, we get:
8 - 2x² = 0
Evaluating for x, we get:
x = +/- √4) = +/- 2
Therefore, the x-coordinate of the inflection points for the function f(x) = ln(x² + 4)
x = - 2 and x = 2 .
The answer is A. x = - 2 and x = 2.

summarize the relationship between the number of Faces, the number of Vertices and the number of Edges of a three-dimensional object
Answer:
The relationship between the number of faces, vertices, and edges of a three-dimensional object is described by Euler's formula, which states that for any polyhedron (a solid object bounded by flat faces), the number of faces (F), vertices (V), and edges (E) satisfy the equation F + V - E = 2. This formula is true for any convex polyhedron, such as a cube or a regular tetrahedron.
The formula is based on the fact that every face of a polyhedron is bounded by a closed loop of edges, and each vertex is where three or more edges meet. The total number of edges is the sum of the number of edges around each face, which is equal to twice the number of faces since each edge is shared by two faces, and the number of edges meeting at each vertex, which is equal to the degree of the vertex (the number of edges meeting at the vertex).
Therefore, by knowing the number of faces, vertices, and edges of a three-dimensional object, we can determine if it is a convex polyhedron and use Euler's formula to check if the numbers are consistent with a solid shape.

A wholesaler will supply 700 of these televisions at $280 each and 1400 at $385 each.
The market equilibrium point is a supply of 1000 at $325
Finding the market equilibrium pointWe have the demand of
800 televisions at $3501200 televisions at $300So, the demand equation is a linear equation that passes through
(800, 350) and (1200, 300)
This equation is
d(x) = -x/8 + 450
We have the supply of
700 televisions at $2801400 televisions at $385So, the supply equation is a linear equation that passes through
(700, 280) and (1400, 385)
This equation is
s(x) = 3x/20 + 175
At the market equilibrium point, we have
d(x) = s(x)
So, we have
3x/20 + 175 = -x/8 + 450
This gives
x = 1000
Also, we have
s(1000) = 3 * 1000/20 + 175
s(1000) = 325

What value of x satisfies the equation −1.5x−2.7=20.1+4.5x
To solve for x in the equation −1.5x−2.7=20.1+4.5x, we need to isolate x on one side of the equation. We can do this by adding 1.5x to both sides of the equation and adding 2.7 to both sides of the equation, which gives us:
-1.5x - 2.7 + 1.5x = 20.1 + 4.5x + 1.5x
Simplifying the left side of the equation and combining like terms on the right side of the equation gives us:
-2.7 = 6x + 20.1
Subtracting 20.1 from both sides of the equation gives us:
-22.8 = 6x
Dividing both sides of the equation by 6 gives us:
x = -3.8
Therefore, the value of x that satisfies the equation is -3.8.

Furniture center offers trade discounts and additional discounts to encourage orders. What is the net price per item if each invoice total is high enough to get additional discount
The customer would pay a net price of $760 per item after all discounts have been applied. It's important to note that the Actual discount percentage and net price per item may vary depending on the terms of the sale and the specific furniture center's policies.
Furniture centers often offer trade discounts to their customers to encourage orders. A trade discount is a reduction in the listed price of a product or service that is offered to trade customers, such as retailers, wholesalers, or other businesses. The discount is usually a percentage of the list price, and the actual amount of the discount depends on the quantity of the product ordered and the terms of the sale.
In addition to trade discounts, furniture centers may offer additional discounts to their customers who meet certain criteria. For example, they may offer a percentage discount for orders over a certain amount or for customers who pay in full at the time of purchase. These additional discounts are intended to encourage customers to place larger orders and to reward them for their loyalty to the furniture center.
To calculate the net price per item, you need to know the list price of the item, the trade discount percentage, and any additional discounts that may apply. For example, let's say that the list price of a piece of furniture is $1,000, and the trade discount offered by the furniture center is 20%. If the customer's invoice total is high enough to qualify for an additional discount of 5%, the net price per item would be calculated as follows:
List price: $1,000
Trade discount: 20% x $1,000 = $200
Price after trade discount: $1,000 - $200 = $800
Additional discount: 5% x $800 = $40
Net price per item: $800 - $40 = $760
So, the customer would pay a net price of $760 per item after all discounts have been applied. It's important to note that the actual discount percentage and net price per item may vary depending on the terms of the sale and the specific furniture center's policies.

Calculus a broad subject that covers many topics such as derivatives, integrals, limits, and functions.
Calculus is a branch of mathematics that focuses on the study of change and motion. It provides a framework for understanding and analyzing quantities that vary continuously. The two main branches of calculus are differential calculus and integral calculus.
Differential calculus deals with the concept of derivatives. A derivative measures how a function changes as its input (usually denoted as x) changes. Geometrically, the derivative represents the slope of a function at a particular point. It can also be interpreted as the instantaneous rate of change of a function at a given point. Derivatives have various applications, such as determining the maximum or minimum values of functions, analyzing the behavior of functions, and solving optimization problems.
Integral calculus, on the other hand, focuses on the concept of integrals. An integral is a mathematical operation that measures the accumulation of quantities or the area under a curve. It essentially reverses the process of differentiation. Integrals can be used to compute the total change or accumulation of a quantity over a given interval, find the area of irregular shapes, and solve problems involving rates of change.
Calculus plays a fundamental role in many scientific and engineering disciplines. It is used extensively in physics, engineering, economics, computer science, and many other fields to model and solve real-world problems involving continuous change. The study of calculus also forms the basis for higher-level mathematics such as differential equations, vector calculus, and multivariable calculus.

How to solve function?A function relates input and output. In other words, a function is an expression that defines a relationship between one variable (the independent variable) and another variable(dependent variable).
Therefore, let's solve the function as follows:

g(x) = x + 3
h(x) = 3x - 4
Therefore,
f(3) = (3)² + 2(3) + 1 = 9 + 6 + 1 = 16
h(0) = 3(0) - 4 = -4
h(g(x)) = 3(x + 3) - 4 = 3x + 9 - 4 = 3x + 5

Apple juice costs $2.50 for 128 ounces. What is the price per ounce?
Answer: $0.0195
Step-by-step explanation: To find the price per ounce of apple juice, we need to divide the total cost by the number of ounces.
Price per ounce = Total cost / Number of ounces
Here, the total cost is $2.50 and the number of ounces is 128.
Price per ounce = $2.50 / 128 ounces
Price per ounce = $0.0195
Therefore, the price per ounce of apple juice is $0.0195, which is approximately 2 cents per ounce.
Answer: $0.0195 per ounce
Step-by-step explanation:
We will create a proportion to help us solve this question.
➜ To do this, we will set two fractions equal to each other with the dollar amount in the numerator and the ounce amount in the denominator.
[tex]\displaystyle \frac{\$2.50}{128\;ounces} =\frac{\$x}{1\;ounce}[/tex]
