Step-by-step explanation:

The general indefinite integral of ∫(x² + 1 + (1/x²+1))dx is (1/3)x³ + x + (1/2)ln|x² + 1| + C

To find the general indefinite integral of ∫(x² + 1 + (1/x²+1))dx, we can use the linearity property of integration and integrate each term separately.

The integral of x² with respect to x is (1/3)x³ + C₁, where C₁ is the constant of integration.

The integral of 1 with respect to x is simply x + C₂, where C₂ is another constant of integration.

To integrate (1/(x²+1)), we can use the substitution method by letting u = x² + 1. Therefore, du/dx = 2x and dx = (1/2x)du. Substituting these expressions, we get:

∫(1/(x²+1))dx = (1/2)∫(1/u)du

= (1/2)ln|u| + C₃

= (1/2)ln|x² + 1| + C₃

where C₃ is another constant of integration.

Therefore, the general indefinite integral of ∫(x² + 1 + (1/x²+1))dx is:

(1/3)x³ + x + (1/2)ln|x² + 1| + C

where C is the constant of integration that accounts for any possible constant differences in the integrals of each term.

In summary, to find the general indefinite integral of a sum of functions, we can integrate each term separately and add up the results, including the constant of integration. When necessary, we can use substitution to simplify the integration process for certain terms.

The Latin future passive personal ending for the 1st person singular of a 3rd / 4th conjugation verb is c) -am.

In Latin, verbs are classified into different conjugations based on their endings.

The 3rd and 4th conjugation verbs are characterized by having a variety of different endings.

When we specifically consider the future passive tense for the 1st person singular, the correct ending is -am.

This ending indicates that the action will be done to the subject in the future and in a passive voice.

Answer:

Obi's age is 18 and Oba's age is 9

Step-by-step explanation:

Let Obi's age be x and Oba's age be y

Condition 1:

x = 2y -----------(1)

Condition 2:

(x-4) = 3(y-4)

=> x -4 = 3y-12

=> x - 3y = -9  -----(2)

Putting eq (1) in (2)

2y - 3y = -9

=> -y = -9

=> y = 9

Now,

x = 2y

=> x = 2(9)

=>  x= 18

Answer:

\(8\\4\)

Step-by-step explanation:

Obi's age is \(x\).

Oba's age is \(2x\).

4 years ago, Obi's age was \(x-4\).

4 years after, Obi's age is \(2x-4\)

3 times more than Oba's, so \(3(x-4)\)

\(2x - 4 = 3( x - 4)\)

\(2x - 4 = 3x-12\)

\(2x - 3x = -12+4\)

\(-1x=-8\)

\(x=8\)

\(x-4\\(8)-4=4\)

Step-by-step explanation:

To find the derivative function f'(t) using only the definition of the derivative, we need to apply the limit definition of the derivative. The derivative function f'(t) for f(t) = 4 + 8t - 5t^2 using only the definition of the derivative is f'(t) = 8 - 10t.

The definition of the derivative of a function f(t) at a point t is given by:

f'(t) = lim(h->0) [f(t + h) - f(t)] / h

Let's apply this definition to the function f(t) = 4 + 8t - 5t^2:

f'(t) = lim(h->0) [(4 + 8(t + h) - 5(t + h)^2) - (4 + 8t - 5t^2)] / h

Expanding and simplifying the expression:

f'(t) = lim(h->0) [4 + 8t + 8h - 5t^2 - 10th - 5h^2 - 10th - 10h^2] / h

Next, we combine like terms:

f'(t) = lim(h->0) [8h - 10th - 5h^2 - 10h^2] / h

Now, we can cancel the common factor of h in the numerator:

f'(t) = lim(h->0) [8 - 10t - 5h - 10h^2] / 1

Taking the limit as h approaches 0, we get:

f'(t) = 8 - 10t

Therefore, the derivative function f'(t) for f(t) = 4 + 8t - 5t^2 using only the definition of the derivative is f'(t) = 8 - 10t.

Answer:

Step-by-step explanation:

The probability that hour 10 is the first sample at which x exceeds 1 is 0.0086.

Let X denotes the number of parts in the sample of 20 that require rework. We can model the number X of parts in a random sample of 20 that require rework with a binomial distribution \($X\sim B(20,0.01)$\). We want to find the probability that the first sample at which X exceeds 1 occurs at hour 10. To do this, we need to compute two probabilities:

- The probability that in the first 9 samples, no sample has more than 1 part needing rework.

- The probability that in the 10th sample, there are at least 2 parts needing rework.

To compute the first probability, we use the binomial distribution with n=20 and p=0.01, and note that each of the first 9 samples is independent. Thus, the probability that no sample in the first 9 has more than 1 part needing rework is

\($$P(X\le 1)^9 = \left(\binom{20}{0}(0.01)^0(0.99)^{20} + \binom{20}{1}(0.01)^1(0.99)^{19}\right)^9 \approx 0.435$$\)

To compute the second probability, we just use the binomial probability mass function with n=20 and p=0.01:

\($$P(X\ge 2) = 1 - P(X=0) - P(X=1) \approx 0.0198$$\)

Finally, we can multiply these probabilities to get the desired probability:

\($P(\text{first sample with } X > 1 \text{ is at hour } 10) = 0.435\times 0.0198 \approx \boxed{0.0086}.$\)

A collection of many linear equations that include the same variables is referred to as a system of linear equations. A linear equation system is often composed of two or more linear equations with two or more variables.A linear equation with two variables, x and y, has the following general form:

                                           \(ax + by = c\)

Given:

Total inhabitants in the village: 817

Number of children: 241

There are 56 more women than men in the village

Total adults = Total inhabitants - Number of children

Total adults = 817 - 241

Total adults = 576

Let number of men in the village be 'x' and number of women in the village be 'y',

∴ y=x+56 (given) ..................(1)

Also, x+y=576 .................(2)

From equation (1) and (2),

x + (x + 56) = 576

2x + 56 = 576

2x = 576 - 56

2x = 520

x = 520 / 2

maybe it is to show the fraction relationship between the teens of the first operation and the terms of the second.

You should not drive faster than the indicated speed limit of 65 mph.

The top speed restriction on most highways is 65 mph. You may drive at 75 mph only if the posted speed limit is 75 mph. Otherwise, you should stay at your speed of 65 mph.

On the other hand, if the average speed of the traffic is 75 mph and you insist on going 65 mph. Then, instead of "moving with the flow," you become an obstruction in the road and put other drivers at graver risk.

A large number of vehicles are approaching you at 10 mph or more. A rear-end collision that may involve numerous cars might happen in the span of a split second of inattention.

We want to find the value of x, which is the hypotenuse of the triangle on the image.

We will see that the value of x is 5.77 units.

On the figure we can see a right triangle, we want to find the value of x, which is the hypotenuse of this triangle.

To do so, we can use the trigonometric relation:

cos(θ) = (adjacent cathetus)/(hypotenuse)

Where θ is an internal angle of the triangle, and the adjacent cathetus is the cathetus that forms the angle.

Here we can use θ = 30°, and the adjacent cathetus is the one that has a measure of 5 units,  then the value of x is given by the equation:

cos(30°) = 5/x

Solving that for x we will get:

x = 5/cos(30°) = 5.77

The system of equations that describes the number of wizards and necromancers in the village is: w + n = 30 n = w + 6.

Let's denote the number of wizards as 'w' and the number of necromancers as 'n'.

From the problem, we know that there are a total of 30 magical people in the village. Therefore, our first equation is simply: w + n = 30. Additionally, we're told that there are six more necromancers than wizards. This means that:

n = w + 6.

We can substitute this second equation into the first to get: w + (w + 6) = 30. Simplifying this equation gives us: 2w + 6 = 30

This is as far as we can simplify the equations without solving for 'w' and 'n'. These equations can be used to determine the values of 'w' and 'n' by solving the system of equations using algebraic methods.

When reflecting over the line y = x, the position of y and x in the original coordinate switches places.

This is because it is " y = x ", assuming that they could interchange

Find the coordinate of Point B'

Original (x, y) = (-2, -4)

Point B' = (x', y') = (y, x) = \(\Large\boxed{(-4,~-2)}\)

Please refer to the attachment below for a graphical understanding

Hope this helps!! :)

Please let me know if you have any questions

The coordinates of B' after the reflection over the line y = x are (-4, -2).

Given that a point B = (-2, -4) has been reflected over the line x = y, we need to find the coordinates of the reflected point B'.

To find the coordinates of point B' after a reflection over the line y = x, we need to understand what a reflection over this line means.

The line y = x is a diagonal line that passes through the points where the x-coordinate and the y-coordinate are equal.

It has a 45-degree angle with both the x-axis and the y-axis. When you reflect a point over this line, you essentially swap its x and y coordinates.

Let's take point B(-2, -4) as an example. To reflect this point over the line y = x, we swap its x and y coordinates:

New x-coordinate of B' = Old y-coordinate of B = -4

New y-coordinate of B' = Old x-coordinate of B = -2

So, the coordinates of B' will be (y, x) = (-4, -2).
