Answer:

2 < x

Step-by-step explanation:

the little circle on 2 is not filled, which means we do not include 2. if it was filled (darkened circle) we include this endpoint.

so, x > 2. in other word 2 < x.

The terms "Fof" and "Dfof" as well as "Gog" and "Dgog" do not have recognized meanings in common usage. Without further context or explanation, it is challenging to provide a precise explanation.



In a hypothetical scenario, "Fof" could represent a function or operation applied to a set or data, and "Dfof" might refer to the domain of that function or the set of inputs on which it operates. Similarly, "Gog" could signify another function or operation, and "Dgog" could represent its domain.

For instance, if "Fof" denotes a function that squares numbers, then "Dfof" would be the set of all possible input values for that function, while "Gog" could represent a different function that takes the square root of a number, and "Dgog" would be the corresponding domain.

However, without specific context or clarification, it is impossible to provide a definitive interpretation. It is crucial to understand the intended meaning of these terms within the specific context in which they are used to provide a more accurate explanation.

To find an antiderivative of the function q(y) = y^6 + 1/y, we can use the power rule and the logarithmic rule of integration. The antiderivative of q(y) is Y = (1/7)y^7 + ln|y| + C, where C is the constant of integration.

To find the antiderivative of y^6, we use the power rule, which states that the antiderivative of y^n is (1/(n+1))y^(n+1). Applying this rule, we find that the antiderivative of y^6 is (1/7)y^7.

To find the antiderivative of 1/y, we use the logarithmic rule of integration, which states that the antiderivative of 1/y is ln|y|. The absolute value sign is necessary to handle the cases when y is negative or zero.

Combining the antiderivatives of y^6 and 1/y, we obtain Y = (1/7)y^7 + ln|y| + C, where C is the constant of integration. The constant of integration accounts for the fact that when we differentiate Y with respect to y, the constant term differentiates to zero.

Therefore, the antiderivative of the function q(y) = y^6 + 1/y is Y = (1/7)y^7 + ln|y| + C.

To find F(x), we integrate the given derivative function. F'(x) = 6 implies that F(x) is the antiderivative of 6 with respect to x, which is 6x + C. To find F"(x), we differentiate F'(x) with respect to x. F"(x) is the derivative of 6x + C, which is simply 6.

To find F(x), we need to integrate the given derivative function F'(x) = 6. Since the derivative of a function gives us the rate of change of the function, integrating F'(x) will give us the original function F(x).

Integrating F'(x) = 6 with respect to x, we obtain:

∫6 dx = 6x + C

Here, C is the constant of integration, which can take any value. So, the antiderivative or the general form of F(x) is 6x + C, where C represents the constant.

To find F"(x), we differentiate F'(x) = 6 with respect to x. Since the derivative of a constant is zero, F"(x) is simply the derivative of 6x, which is 6.

False. Not every autonomous differential equation is a separable differential equation.

A separable differential equation is a type of differential equation that can be written in the form dy/dx = f(x)g(y), where f(x) and g(y) are functions of x and y, respectively. In a separable differential equation, the variables x and y can be separated and integrated separately.

On the other hand, an autonomous differential equation is a type of differential equation where the derivative is expressed solely in terms of the dependent variable. In other words, the equation does not explicitly depend on the independent variable.

While some autonomous differential equations may be separable, it is not true that every autonomous differential equation can be expressed as a separable differential equation.

Autonomous differential equations can take various forms, and not all of them can be transformed into the separable form. Some autonomous equations may require other techniques or methods for their solution, such as linearization, substitution, or numerical methods.

The slope-intercept form of the equation is y = 2x.

To find the point-slope form of a line, we use the formula:

y - y₁ = m(x - x₁),

where (x₁, y₁) represents a point on the line, and m is the slope of the line. Given two points, (7,14) and (8,16), we can calculate the slope (m) using the formula: m = (y₂ - y₁) / (x₂ - x₁),

where (x₂, y₂) represents the second point. Plugging in the values, we get:

m = (16 - 14) / (8 - 7) = 2.

Now we can use the point-slope form with either of the two points. Let's use (7,14):

y - 14 = 2(x - 7).

To convert this to the slope-intercept form (y = mx + b), we simplify:

y - 14 = 2x - 14,

y = 2x.

Therefore, the slope-intercept form of the equation is y = 2x.

The line integral of the given function, ∫_c y²dx+xdy, along the arc of the parabola x = 4 - y² from (-5, -3) to (0, 2), can be evaluated by parameterizing the curve and then calculating the integral using the parameterization.

To evaluate the line integral, we first need to parameterize the given curve. Since the parabola is defined by x = 4 - y², we can choose y as the parameter. Let's denote y as t, where t varies from -3 to 2. Then, we can express x in terms of t as x = 4 - t².

Next, we differentiate the parameterization to obtain dx/dt = -2t and dy/dt = 1. Now, we substitute these values into the line integral expression: ∫_c y²dx + xdy = ∫_c y²(-2t)dt + (4 - t²)dt.

Now, we integrate with respect to t, using the limits of -3 to 2, since those are the parameter values corresponding to the given endpoints. After integrating, we obtain the value of the line integral.

If the sample size is multiplied by 4, the standard deviation of the distribution of sample means, also known as the standard error, is affected as follows: The standard error is halved. So, the correct answer is D) The standard error is halved.

b. The first derivative of g(t) = f'(t^2 + 2) is 56t(t^2 + 2)

c. The first derivative of v(s) is v'(s) = 2s / (s^2 - 4), and the second derivative is v''(s) = (-2s^2 - 8) / (s^2 - 4)^2.

d.  The first derivative of h(x) is h'(x) = -3, and the second derivative is h''(x) = 0.

(a) To compute the first and second derivatives of the function f(x) = 14x^2 - 12, we'll differentiate each term separately.

First derivative:

f'(x) = d/dx (14x^2 - 12)

= 2(14x)

= 28x

Second derivative:

f''(x) = d^2/dx^2 (14x^2 - 12)

= d/dx (28x)

= 28

Therefore, the first derivative of f(x) is f'(x) = 28x, and the second derivative is f''(x) = 28.

(b) To find the first derivative of g(t) = f'(t^2 + 2), we need to apply the chain rule. The chain rule states that if h(x) = f(g(x)), then h'(x) = f'(g(x)) * g'(x).

Let's start by finding the derivative of f(x) = 14x^2 - 12, which we computed earlier as f'(x) = 28x.

Now, we can apply the chain rule:

g'(t) = d/dt (t^2 + 2)

= 2t

Therefore, the first derivative of g(t) = f'(t^2 + 2) is:

g'(t) = f'(t^2 + 2) * 2t

= 28(t^2 + 2) * 2t

= 56t(t^2 + 2)

(c) To compute the first and second derivatives of v(s) = ln(s^2 - 4), we'll apply the chain rule and the derivative of the natural logarithm.

First derivative:

v'(s) = d/ds ln(s^2 - 4)

= 1 / (s^2 - 4) * d/ds (s^2 - 4)

= 1 / (s^2 - 4) * (2s)

= 2s / (s^2 - 4)

Second derivative:

v''(s) = d/ds (2s / (s^2 - 4))

= (2(s^2 - 4) - 2s(2s)) / (s^2 - 4)^2

= (2s^2 - 8 - 4s^2) / (s^2 - 4)^2

= (-2s^2 - 8) / (s^2 - 4)^2

Therefore, the first derivative of v(s) is v'(s) = 2s / (s^2 - 4), and the second derivative is v''(s) = (-2s^2 - 8) / (s^2 - 4)^2.

(d) To compute the first and second derivatives of h(x) = 523 - 3x + 14, note that the derivative of a constant is zero.

First derivative:

h'(x) = d/dx (523 - 3x + 14)

= -3

Second derivative:

h''(x) = d/dx (-3)

= 0

Therefore, the first derivative of h(x) is h'(x) = -3, and the second derivative is h''(x) = 0.

The value of the integral ∫(4r / √(14+2r^2)) dr is 2√(14+2r^2) + C.

To evaluate the integral ∫(4r / √(14+2r^2)) dr, we can use the substitution method. Let's make the substitution u = 14 + 2r^2. To find the differential du, we take the derivative of u with respect to r: du = 4r dr. Rearranging this equation, we have dr = du / (4r).

Substituting the values into the integral, we get: ∫(4r / √(14+2r^2)) dr = ∫(du / √u).

Now, the integral becomes ∫(1 / √u) du. We can simplify this integral by using the power rule of integration, which states that the integral of x^n dx equals (x^(n+1) / (n+1)) + C, where C is the constant of integration.

Applying the power rule, we have: ∫(1 / √u) du = 2√u + C. Substituting the original variable back in, we have:2√(14+2r^2) + C. Therefore, the value of the integral ∫(4r / √(14+2r^2)) dr is 2√(14+2r^2) + C.

The fundamental difference between the t statistic and a z statistic is that the t statistic computes the standard error by dividing the standard deviation by n-1 instead of dividing by n so the correct answer is option (c).

This is because the t statistic is used when the population standard deviation is unknown, and the sample standard deviation is used as an estimate. Therefore, the formula for the standard error of the t statistic adjusts for the fact that the sample standard deviation may not be an exact reflection of the population standard deviation.

Additionally, the t statistic also uses the sample mean in place of the population mean, which is another difference from the z statistic. The z statistic assumes that the population mean is known, while the t statistic is used when the population mean is unknown. Finally, the t statistic uses the sample variance in place of the population variance, which is yet another difference between the two statistics.

Next, we substitute y' into the expression y' + ky:

y' + ky = (-Aksin(kt) + Bkcos(kt)) + k(Acos(kt) + Bsin(kt))

To find the equation of the tangent to the ellipse at a given point, we need to calculate the derivative of the ellipse equation with respect to x.

The equation of the ellipse is given by x^2 + 3y^2 - 76 = 0. By differentiating implicitly with respect to x, we obtain the derivative:

2x + 6y(dy/dx) = 0

Solving for dy/dx, we have:

dy/dx = -2x / (6y) = -x / (3y)

Now, let's find the equation of the tangent at each given point:

(a) Point (7, 3):

Substituting x = 7 and y = 3 into the equation for dy/dx, we find dy/dx = -7 / (3*3) = -7/9. Using the point-slope form of a line (y - y0 = m(x - x0)), we can write the equation of the tangent as y - 3 = (-7/9)(x - 7), which simplifies to y = (-7/9)x + 76/9.

(b) Point (-7, 3):

Substituting x = -7 and y = 3 into dy/dx, we get dy/dx = 7 / (3*3) = 7/9. Using the point-slope form, the equation of the tangent becomes y - 3 = (7/9)(x + 7), which simplifies to y = (7/9)x + 76/9.

(c) Point (1, -5):

Substituting x = 1 and y = -5 into dy/dx, we obtain dy/dx = -1 / (3*(-5)) = 1/15. Using the point-slope form, the equation of the tangent is y - (-5) = (1/15)(x - 1), which simplifies to y = (1/15)x - 76/15.

In summary, the equations of the tangents to the ellipse at the given points are:

(a) (7, 3): y = (-7/9)x + 76/9

In this scenario, each new employee can either be a good fit (g) or a bad fit (b). Since each outcome is equally likely, we can determine the probability of all three employees being a good fit by considering the total number of equally likely outcomes.

For each employee, there are two possible outcomes (good fit or bad fit). Therefore, the total number of equally likely outcomes for three employees is 2 * 2 * 2 = 8.

Out of these 8 outcomes, we are interested in the specific outcome where all three employees are a good fit (g, g, g). There is only one such outcome.

Hence, the probability of all three new employees being a good fit is 1 out of 8 possible outcomes, which can be expressed as 1/8.

Therefore, if each outcome in the sample space is equally likely, the probability that all of the new employees will be a good fit is 1/8.

The required value of x is 18.4.

Given the right-angled triangle with hypotenuse is x and one side is equal to 13 and angle is 45°.

To find the one side of the triangle by using the trigonometric functions  tan a and then use Pythagoras theorem to find the value of x.

Pythagoras theorem states that [tex]hypotenuse^2 = base^2 + perpendicular^2[/tex].

In triangle, tan a = perpendicular / base.

That implies, tan 45° = 13/x

On evaluating the value tan 45° = 1 gives,

1 = 13/ x

on cross multiplication gives,

x = 13.

By using Pythagoras theorem, find the base of the triangle,

[tex]hypotenuse^2 = base^2 + perpendicular^2[/tex].

[tex]x^{2} = 13^2 +13^2[/tex]

[tex]x^{2}[/tex] = 2 ×[tex]13^{2}[/tex]

take square root on both sides gives,[tex]\sqrt{2}[/tex]

x = 13 [tex]\sqrt{2}[/tex]

x = 13 × 1.141

x  = 18.38

Rounding off to tenths gives,

x = 18.4.

Hence, the required value of x is 18.4.
