I assume you're needing to find \((f+g)(x)\) given those two functions you have.

    \(\begin{aligned}(f+g)(x) &= f(x) + g(x) \\[0.5em] &= (5x^3+5x^2-6x+3) + (x^3-4x^2+x-2)\end{aligned}\)

From there, you combine like terms:

    \(\begin{aligned}(f+g)(x) &= f(x) + g(x) \\[0.5em] &= (5x^3+5x^2-6x+3) + (x^3-4x^2+x-2) \\[0.5em] &= 6x^3+x^2-5x+1\end{aligned}\)

Thus, the general solution of the given differential equation is: y = c1 + c2e^(-x/8) where c1 and c2 are constants determined by the initial or boundary conditions.

To find the general solution of the given differential equation, we first need to find the characteristic equation by assuming a solution of the form y = e^(rt), where r is a constant.

Substituting this into the differential equation, we get:

8(e^(rt))'' + (e^(rt))' = 0

Simplifying, we get:

8r^2e^(rt) + re^(rt) = 0

Factoring out e^(rt), we get:

In general, the Divergence Test (nth term test) only allows us to determine whether a series diverges or not. It does not help us to determine the convergence of a series. Therefore, none of the other tests apply to this series.

The Divergence Test (nth term test) states that if the limit of the nth term of a series is not equal to zero, then the series diverges.

The series [infinity] 12 n n=1 is defined as follows:

[infinity] 12 n n=1 = 12¹ + 12² + 12³ + ...

The nth term of this series is given by:

aₙ = 12ⁿ As n → ∞, aₙ → ∞,

which means the limit of the nth term of the series does not exist.

Therefore, the series [infinity] 12 n n=1 diverges by the Divergence Test (nth term test).

Answer:

Finding the vertex by completing the square

1) The vertex = (4/3, -4/3)

2) The vertex = (-1/2, 36)

3) The vertex = (2/3, 26/3)

Finding the value of x by completing the square

1) x = 1 or -4

2) x = 3/2 or -7/2

3) x = 1 or -3

Step-by-step explanation:

Finding the vertex by completing the square

The vertex form of the quadratic equation y = ax² + bx + c is written as follows;

y = a(x - h) + k

Therefore, we have;

Y = 3·x² + 4 - 8·x = a(x - h)² + k

Hence, a  = 3

Which gives;

3×(x² - 2·x·h + h²) + k

Hence, we have 3×2×h = 8

h = 8/6 = 4/3

The constant term = k

We note that 3 × h² + k = 4

∴ k = 4 - 16/3 = -4/3

The vertex form is therefore;

Y = 3(x - 4/3)² - 4/3

The vertex = (4/3, -4/3)

2) Where Y = 4·x² + 4·x + 36

a = 4

4× -2·h = 4

∴ h = 4/(4 × (-2)) = 4/-8 = -1/2

Also, 4 × h² + k = 36

Which gives;

4 × (-1/2)² × k = 36

k = 36

The vertex form becomes

y = 4(x - (-1/2)) + 36

The vertex = (-1/2, 36)

3) Where Y = -3·x² + 4·x + 10, we have

a = -3

3×2×h = 4

∴ h = 4/(2×3) = 2/3

a×h² + c = k

-(3)×(2/3)² + 10 =  26/3

Which gives;

Y = -3(x - 2/3) + 26/3

The vertex = (2/3, 26/3)

To find the value of x by completing the square, we have;

1) 2·x² = -6·x + 8

2·x² + 6·x =  8

2·(x² + 3·x) = 8

x² + 3·x = 8/2 = 4

x² + 3·x + (3/2)² = 4 + (3/2)² = 25/4

(x + 3/2)² = 25/4

∴ x + 3/2 = ±5/2

x = 5/2 - 3/2 or -5/2 - 3/2

x = 1 or -4

2) 8·x² + 16·x = 42

8·(x² + 2·x) = 42

x² + 2·x = 42/8 = 21/4

x² + 2·x + 1 = 21/4 + 1 = 25/4

(x + 1)² = 25/4

x + 1 = √(25/4) = ± 5/2

x = 5/2 - 1 or -5/2 - 1

∴ x = 3/2 or -7/2

3) -x² + 2·x = -3

-x² + 2·x = -3

-1×(-x² + 2·x) = -1 ×-3 = 3

x² - 2·x = 3

x² - 2·x + 1 = 3 + 1 = 4

(x - 1)² = 4

x - 1 = √4 = ±2

∴ x = 2 - 1 or -2 - 1

x = 1 or -3

The principle that refers to an insured being entitled to coverage under a policy that a prudent person would expect it to provide is called reasonable expectations. The correct answer is C.

The principle of "reasonable expectations" in insurance refers to the understanding that an insured individual should reasonably expect coverage from their insurance policy based on the language and terms presented in the policy.

It is based on the idea that insurance contracts should be interpreted in a way that aligns with the insured's reasonable understanding of the coverage they have purchased.

When individuals enter into an insurance contract, they rely on the representations made by the insurance company and the policy wording to determine the extent of coverage they will receive in the event of a loss or claim.

The principle of reasonable expectations recognizes that the insured may not have the same level of expertise or knowledge as the insurance company in understanding the complex legal language of the policy.

The domain of the Riemann zeta function, denoted by ζ(x), is the set of real numbers x for which the series ∑n=1 ∞ n^(-x) converges. The domain of the function can be expressed using interval notation as (-∞, 1).

To understand the domain of the Riemann zeta function, we need to consider the convergence of the series ∑n=1 ∞ n^(-x). The series converges when the real part of x is greater than 1. Therefore, the right half-plane Re(x) > 1 represents a region where the series converges.

On the other hand, when the real part of x is less than or equal to 1, the series diverges. This means that the left half-plane Re(x) ≤ 1 is excluded from the domain of the Riemann zeta function.

Combining these conditions, we find that the domain of the Riemann zeta function is (-∞, 1) in interval notation, indicating that the function is defined for all real numbers less than 1.

Answer: .416666667

Step-by-step explanation: Take 80 and divide it by 192.0= .416666667

Using a system of equations:

a)

The system is:

\(x + y = 58\)

\(y = 2x + 4\)

b)

Robin is 18 years old and Batman is 40 years old.

-------------------------

Item a:

Batman's age is 4 more than twice of robins age.

Thus, \(y = 2x + 4\)

Sum of the ages is 58, thus:

\(x + y = 58\)

Then, the system is:

\(x + y = 58\)

\(y = 2x + 4\)

Item b:

Applying the second equation into the first:

\(x + y = 58\)

\(x + 2x + 4 = 58\)

\(3x = 54\)

\(x = \frac{54}{3}\)

\(x = 18\)

Then, for y:

\(y = 2x + 4 = 2(18) + 4 = 36 + 4 = 40\)

Robin is 18 years old and Batman is 40 years old.

Answer:

x is 33

Step-by-step explanation:

All 3 of these angles added together create a straight line, and such lines always measure 180°, so if we create an equation with the 3 angles being added together, set it equal to 180, and solve, we'll find the answer:

104+x+(x+10)=180

104+x+x+10=180 (use the distributive property to remove parenthesis)

104+10+x+x=180 (rearrange terms)

114+2x=180 (combine like terms)

2x=180-114 (subtract 114 from both sides)

2x=66

x=33 (divide 2 from both sides)

Answer:

The answer should be D.

Step-by-step explanation:

You do the elimination process.

Answer:

D

Step-by-step explanation:

5x + 3y = 18 → (1)

2x - 3y = 10 → (2)

adding the 2 equations term by term will eliminate the y- term

7x + 0 = 28

7x = 28 ( divide both sides by 7 )

x = 4

substitute x = 4 into either of the 2 equations and solve for y

Substituting into (1)

5(4) + 3y = 18

20 + 3y = 18 ( subtract 20 from both sides )

3y = - 2 ( divide both sides by 3 )

y = - \(\frac{2}{3}\)

Answer:

Mr. A initially paid approximately N8000 for the land.

Step-by-step explanation:

Step 1: Let's assume Mr. A initially purchased the land for a certain amount, which we'll call "x" in currency units.

Step 2: Mr. A sold the land to Mr. B at a profit of 10%. This means Mr. A sold the land for 110% of the amount he paid (1 + 10/100 = 1.10). Therefore, Mr. A received 1.10x currency units from Mr. B.

Step 3: Mr. B sold the land to Mr. C at a gain of 5%. This means Mr. B sold the land for 105% of the amount he paid (1 + 5/100 = 1.05). Therefore, Mr. B received 1.05 * (1.10x) currency units from Mr. C.

Step 4: According to the given information, Mr. C paid N1240 more for the land than Mr. A paid. This means the difference between what Mr. C paid and what Mr. A paid is N1240. So we have the equation: 1.05 * (1.10x) - x = N1240

Step 5: Simplifying the equation: 1.155x - x = N1240

Step 6: Solving for x: 0.155x = N1240

x = N1240 / 0.155

x ≈ N8000

Therefore, in conclusion, Mr. A initially paid approximately N8000 for the land.

The percentage of batteries that have **s-scores** between -2 and 2 can be estimated using the standard normal distribution.

To calculate the percentage, we can use the properties of the standard normal distribution. The area under the standard normal curve between -2 and 2 represents the percentage of values within that range. Since the data is approximately bell-shaped and the standard deviation is known, we can use the properties of the standard normal distribution to estimate this percentage.

Using a standard normal distribution table or a calculator, we find that the area under the curve between -2 and 2 is approximately 95.45%. Therefore, we can estimate that approximately **95.45%** of the batteries will have s-scores between -2 and 2.

It is important to note that the use of s-scores and z-scores is interchangeable in this context since we are dealing with a known standard deviation.

(C) Regression analysis is the statistical method commonly used to estimate the level and trend in a time series by modeling the relationship between the data and independent variables.

Regression analysis is the statistical method used to estimate the level and trend in a time series. Time series data represents observations taken at different points in time and is commonly used to analyze trends and patterns over time.

Regression analysis allows us to model the relationship between a dependent variable (in this case, the time series data) and one or more independent variables (such as time or other relevant factors). By using regression analysis, we can identify the underlying trend in the time series and estimate its level.

The regression model captures the relationship between the dependent variable (the time series) and the independent variable(s) by fitting a line or curve that best represents the data. This line or curve helps to identify the overall trend and level of the time series.

While moving average, simulation method, covariance analysis, and correlation analysis are useful techniques in analyzing time series data, they are not specifically designed to estimate the level and trend in a time series. Therefore, (C) regression analysis is the most appropriate method for estimating the level and trend in a time series.
