The real values of x are -10 and 10

From the question, we have the following parameters that can be used in our computation:

(x^2 - 82)^2 = 324

Take the square roots of both sides

So, we have

x^2 - 82 = 18

Add 82 to both sides of the equation

So, we have the following representation

x^2 = 100

Let the element of R^2 be (x, y).

(x, y) = [tex]c_{1}[/tex](-1, 4) + [tex]c_{2}[/tex](4, −1) + [tex]c_{3}[/tex](3, 3)

The largest interval I over which the general solution is defined is (-∞, ∞).

A differential equation is a mathematical equation that relates an unknown function to its derivatives. It expresses the relationship between an dependent variable (the unknown function) and one or more independent variables. Differential equations are used to model physical, biological, and economical systems, among others.

A differential equation can be thought of as an equation that describes how a function changes over time. For example, the velocity of an object is the derivative of its position with respect to time. If the position of the object is modeled by a function, then its velocity can be described by a differential equation.

ODEs deal with functions of a single variable and their derivatives, while PDEs deal with functions of multiple variables and their partial derivatives.

The given differential equation is a first-order linear ordinary differential equation with constant coefficients:

dy/dx + y = e⁷ˣ

This equation can be solved using the method of integrating factors. The integrating factor is given by e^∫1 dx = e^x. Multiplying both sides of the equation by the integrating factor, we get:

eˣ(dy/dx) + eˣ y = e⁸ˣ

Integrating both sides, we get:

eˣ y = e⁸ˣ - eˣ + C, where C is an arbitrary constant of integration.

Dividing both sides by eˣ, we get the general solution:

y = e⁷ˣ + Ce⁻ˣ

The area of mathematics known as probability explores potential outcomes of events, along with the likelihoods and distributions of those occurrences.

What is meant by probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability. Calculating a result or an event's likelihood is known as simple probability. To calculate the likelihood of having to pay out a claim, insurance firms employ probability statistics. A simple probability is computed by dividing a particular result by all potential results.

The domain of the function f(x) = 10x + 8 will be all x values such that 0 ≤ x < 248.

The domain of a function is the set of all possible input values for which the function is defined. For the function f(x) = 10x + 8, the domain will be all real numbers greater than or equal to 0. This can be seen by examining the equation: if x = 0, then f(x) = 8. Therefore, the domain of the function will be all x values such that x ≥ 0. To calculate the upper bound for the domain, we can solve for x by subtracting 8 from both sides of the equation, resulting in 10x = -8. Dividing both sides by 10 gives us x = -0.8. Therefore, the domain of the function f(x) = 10x + 8 will be all x values such that 0 ≤ x < 248.

You need to work 84 hours per month at your second job to meet your monthly savings goal.

Fixed expenses = 2,034.24 x 30% = $610.72

Discretionary income = 2,034.24 - 610.72 = $1,423.52

Savings goal per month = $1,423.52 x 20% = $284.70

Net pay per hour = $9.50 - ($9.50 x 7.65%) - ($9.50 x 11.5%) - ($9.50 x 7.75%) = $7.33

Hours per month = $284.70 ÷ $7.33 = 84 hours.

To calculate, first find the number of your fixed expenses by multiplying your primary job income by 30%. This is $610.72. Then subtract your fixed expenses from your primary job income to find your discretionary income, which is $1,423.52. Multiply that by 20% to find the amount you want to save each month, which is $284.70.

The output of the function can be calculated by plugging in 2 for x and evaluating the equation:[tex]f(2) = 2(2^3) + 5(2^2) - 7(2) + 4 = 16 + 20 - 14 + 4 = 26.[/tex]

The Common Core standards for Pre-Calculus focus on the study of functions and their applications, as well as the development of a deeper understanding of the algebraic and geometric principles in the mathematical field. One of the core concepts covered in Pre-Calculus is the concept of polynomial functions. A polynomial function is an expression made up of terms that involve only constants, variables, and exponents. It is represented by the equation [tex]f(x) = ax^n + bx^n-1 + cx^n-2 + … + z[/tex], where a, b, c, …, z are constants and n is a non-negative integer. To find the value of a polynomial function at a given value of x, the equation can be evaluated by plugging in the x value and calculating the output. For example, if a polynomial function is represented by the equation f(x) = 2x^3 + 5x^2 - 7x + 4, and the x value is 2, then the output of the function can be calculated by plugging in 2 for x and evaluating the equation: [tex]f(2) = 2(2^3) + 5(2^2) - 7(2) + 4 = 16 + 20 - 14 + 4 = 26.[/tex]

Two lines are parallel if and only if they have the same slope. So, to find the value of y, we need to find the slope of the first line segment and use it to find the equation of the second line segment.

The slope of the first line segment can be found using the formula:

Since the two lines are parallel, they have the same slope, so we can use the slope to find the equation of the second line segment.

Expanding the equation and solving for y, we get:

Answer: Diploid cells divide to form four haploid daughter cells during mitosis.

Step-by-step explanation:

The answer is: Sister chromatids separate to form haploid daughter cells during meiosis.

One of a chromosome's two identical halves that has undergone replication in order to facilitate cell division is referred to as a chromatid. A chromosomal region known as the centromere is where the two "sister" chromatids are fused.

One of the two identical copies of a duplicated chromosome is called a chromatid. At the centromere, a portion of the chromosome, the twin copies of the DNA join together during cell division. Sister chromatids are those that are joined. A chromosome is a protein and DNA-based structure that resembles a thread. It contains an organism's whole genetic makeup. Parents pass this on to their children. One of a chromosome's halves is called a chromatid. There is just one chromatid per chromosome.

The chromatids in each thread-like structure in the chromosome are the result of the chromosome's DNA replicating itself. Haploid cells are produced as a result of the segregation of the chromatids during meiosis II.

When the temperature is constant, it means that one of the variables that can affect the demand for balloon rides is eliminated. This allows us to focus on the relationship between balloon rides and price. The relationship between these two variables can be represented by a curve. The curve can show us how the price of a balloon ride changes as the number of rides changes.

Then table for the relationship between balloon rides and price when the temperature is constant at 50 degrees is attached below.

when the temperature is constant, the relationship between balloon rides and price can be shown by a curve. The shape of the curve will depend on the relationship between the two variables, which can be upward-sloping, downward-sloping, or remain constant.
