The integral becomes:

∫(4t⁵ + 6)t⁴ dt = (2/5)t¹⁰ + (6/5)t⁵ + C

The integral in terms of u is:

∫(4t⁵ + 6)t⁴ dt = (2/5)t¹⁰ + (2/5)t⁻³ + C = ∫ (2/5)(u²) + (2/5)u⁻³ du

The evaluated integral is:

∫(4t⁵ + 6)t⁴ dt = (2/15)t¹⁵ - (1/5)t⁻¹⁰ + C

The summing of discrete data is indicated by the integration. To determine the functions that will characterize the area, displacement, and volume that result from a combination of small data that cannot be measured separately, integrals are calculated.

To evaluate the integral ∫(4t⁵ + 6)t⁴ dt, we can use the power rule of integration.

∫(4t⁵ + 6)t⁴ dt = ∫4t⁹ + 6t⁴ dt

Using the power rule, we can integrate each term separately:

∫4t⁹ dt = (4/10)t¹⁰ + C₁ = (2/5)t¹⁰ + C₁

∫6t⁴ dt = (6/5)t⁵ + C₂

Therefore, the integral becomes:

∫(4t⁵ + 6)t⁴ dt = (2/5)t¹⁰ + (6/5)t⁵ + C

Now, to determine the change of variables from t to u, we can let u = t⁵. Taking the derivative of u with respect to t, we get:

du/dt = 5t⁴

Rearranging the equation, we have:

dt = (1/5t⁴) du

Substituting this back into the integral, we get:

∫(4t⁵ + 6)t⁴ dt = ∫(4u + 6)(1/5t⁴) du

Simplifying further:

∫(4t⁵ + 6)t⁴ dt = (4/5)∫u du + (6/5)∫(1/t⁴) du

∫(4t⁵ + 6)t⁴ dt = (4/5)∫u du - (6/5)∫t⁻⁴ du

∫(4t⁵ + 6)t⁴ dt = (4/5)(u²/2) - (6/5)(-t⁻³/3) + C

∫(4t⁵ + 6)t⁴ dt = (2/5)u² + (2/5)t⁻³ + C

Since we substituted u = t⁵, we can replace u and simplify the integral:

∫(4t⁵ + 6)t⁴ dt = (2/5)(t⁵)² + (2/5)t⁻³ + C

∫(4t⁵ + 6)t⁴ dt = (2/5)t¹⁰ + (2/5)t⁻³ + C

Therefore, the integral in terms of u is:

∫(4t⁵ + 6)t⁴ dt = (2/5)t¹⁰ + (2/5)t⁻³ + C = ∫ (2/5)(u²) + (2/5)u⁻³ du

To evaluate the integral, we can integrate each term:

∫ (2/5)(u²) + (2/5)u⁻³ du = (2/5)(u³/3) + (2/5)(-u⁻²/2) + C

Simplifying further:

∫ (2/5)(u²) + (2/5)u⁻³ du = (2/15)u³ - (1/5)u⁻² + C

Since we substituted u = t⁵, we can replace u and simplify the integral:

∫ (2/5)(u²) + (2/5)u⁻³ du = (2/15)(t⁵)³ - (1/5)(t⁵)⁻² + C

∫ (2/5)(u²) + (2/5)u⁻³ du = (2/15)t¹⁵ - (1/5)t⁻¹⁰ + C

Therefore, the evaluated integral is:

The volume of the solid that lies under the paraboloid z = x² + y², above the xy-plane, and inside the cylinder r² + y² = 2y can be found by evaluating a double integral. The correct integral to compute the volume is given by: ∬[D] (x² + y²) dA and as a result the exact value of the volume of the solid turns out to be 2/3.

where D represents the region of integration defined by the intersection of the paraboloid and the cylinder. To evaluate this integral, we can use either Cartesian or polar coordinates. Since the given equation of the cylinder is in polar form, it is convenient to use polar coordinates. In polar coordinates, the equation of the cylinder can be rewritten as r² - 2rcosθ + y² = 0. Solving for r, we get r = 2cosθ. The limits of integration for r and θ can be determined by the intersection points of the paraboloid and the cylinder. The paraboloid intersects the cylinder when z = x² + y² = r²sin²θ + r² = r²(sin²θ + 1). Setting this equal to 2y, we have r²(sin²θ + 1) = 2r sinθ.

Simplifying, we get r²sin²θ + r² - 2r sinθ = 0. Dividing by r and rearranging, we have r(sinθ - 1) = 0. This implies r = 0 or sinθ = 1. Since we are interested in the region inside the cylinder, we can disregard r = 0. Hence, the limits for r are 0 to 2cosθ. The limits for θ can be determined by the range of θ for which the intersection occurs. From sinθ = 1, we have θ = π/2.

Therefore, the volume of the solid can be calculated as: V = ∫[0 to π/2] ∫[0 to 2cosθ] r²sinθ dr dθ

To evaluate the double integral V = ∫[0 to π/2] ∫[0 to 2cosθ] r²sinθ dr dθ, we integrate with respect to r first, and then with respect to θ. ∫[0 to π/2] ∫[0 to 2cosθ] r²sinθ dr dθ

Integrating with respect to r, we get:

= ∫[0 to π/2] [1/3 r³sinθ] evaluated from 0 to 2cosθ dθ

= ∫[0 to π/2] (1/3)(8cos³θ)sinθ dθ

= (8/3) ∫[0 to π/2] cos³θsinθ dθ

Next, we integrate with respect to θ:

= (8/3) [(-1/4)cos⁴θ] evaluated from 0 to π/2

= (8/3) [(-1/4)(0⁴ - 1⁴)]

= (8/3) [(-1/4)(-1)]

= (8/3) * (1/4)

= 2/3

Therefore, the exact value of the volume of the solid is 2/3.

After calculations we find out that the interval on which f(x) = 2x + 2x – 1 is increasing is x > -1/2 and the interval on which it is decreasing is x < -1/2.

Given function is f(x) = 2x + 2x – 1.

First derivative of the given function is f'(x) = 4x + 2.

If the first derivative is positive, then the function is increasing and if the first derivative is negative, then the function is decreasing.

If the first derivative is equal to zero, then it is a critical point.

So, we have to find the interval on which the function is increasing or decreasing.

Now, we will find the critical point of the function, which is f'(x) = 0. 4x + 2 = 0⇒ 4x = -2⇒ x = -2/4⇒ x = -1/2.Now, we will find the interval of the function. The interval of the function is given by x < -1/2, x > -1/2.

To check the function is increasing or decreasing, we have to use the first derivative. Let's check the function is increasing or decreasing by the first derivative. f'(x) > 0 ⇒ 4x + 2 > 0 ⇒ 4x > -2 ⇒ x > -1/2.

This means the function is increasing on the interval x > -1/2.f'(x) < 0 ⇒ 4x + 2 < 0 ⇒ 4x < -2 ⇒ x < -1/2.

This means the function is decreasing on the interval x < -1/2.

Therefore, the interval on which f(x) = 2x + 2x – 1 is increasing is x > -1/2 and the interval on which it is decreasing is x < -1/2.

The first derivative of the function g(x) = 6.23 - 1822 - 144x is g'(x) = -144.

To determine if there is a local minimum at x = -2, we need to analyze the concavity of the function. Since g'(x) is a constant (-144), it means the function g(x) is linear, and there are no local maxima or minima.

The function has a constant negative slope of -144, indicating a downward linear trend. Therefore, there is no local minimum at x = -2.

If we were to find a local minimum, we would need a function whose first derivative is zero at that point, followed by a change in sign of the derivative.

However, in this case, the derivative is always -144, which means the slope is constant throughout and there are no turning points or local extrema.

To solve the linear differential equation (x + 2)y' = 0 by using the separation of variables method, subject to the initial condition y(4) = 1, we can divide both sides of the equation by (x + 2) to separate the variables and integrate.

Starting with the given differential equation, (x + 2)y' = 0, we divide both sides by (x + 2) to obtain y' = 0. This step allows us to separate the variables, with y on one side and x on the other side. Integrating both sides gives us ∫dy = ∫0 dx.

The integral of dy is simply y, and the integral of 0 with respect to x is a constant, which we'll call C. Therefore, we have y = C as the general solution. To find the specific solution that satisfies the initial condition y(4) = 1, we substitute x = 4 and y = 1 into the equation y = C. This gives us 1 = C, so the specific solution is y = 1.

The solution to the differential equation y' = 8y + [tex]x^_2[/tex], using integrating factors, is y = ([tex]x^_2[/tex]- 2x + 2) + [tex]Ce^_(-8x)[/tex].

To address the given differential condition, y' = 8y + [tex]x^_2[/tex], we can utilize the technique for coordinating elements.

The standard type of a direct first-request differential condition is y' + P(x)y = Q(x), where P(x) and Q(x) are elements of x. For this situation, we have P(x) = 8 and Q(x) = x^2[tex]x^_2[/tex].

The coordinating variable, indicated by I(x), is characterized as I(x) = [tex]e^_(∫P(x) dx)[/tex]. For our situation, I(x) = [tex]e^_(∫8 dx)[/tex]=[tex]e^_(8x).[/tex]

Duplicating the two sides of the differential condition by the coordinating variable, we get:

[tex]e^_(8x)[/tex] * y' + 8[tex]e^_(8x)[/tex]* y = [tex]e^_(8x)[/tex] * [tex]x^_2.[/tex]

Presently, we can rework the left half of the situation as the subsidiary of ([tex]e^_8x[/tex] * y):

(d/dx) [tex](e^_(8x)[/tex] * y) = [tex]e^_8x)[/tex]* [tex]x^_2[/tex].

Coordinating the two sides regarding x, we have:

[tex]e^_(8x)[/tex]* y = ∫([tex]e^_(8x)[/tex]*[tex]x^_2[/tex]) dx.

Assessing the basic on the right side, we get:

[tex]e^_(8x)[/tex] * y = (1/8) * [tex]e^_(8x)[/tex] * ([tex]x^_2[/tex] - 2x + 2) + C,

where C is the steady of reconciliation.

To express the surface area of the portion of the paraboloid 2z = x^2 + y^2 that lies between the planes z = 1 and z = 2 as a double integral in polar coordinates, we need to convert the Cartesian coordinates (x, y, z) to polar coordinates (r, θ, z).

In polar coordinates, we have:

x = r*cos(θ),

y = r*sin(θ),

z = z.

The equation of the paraboloid in polar coordinates becomes:

2z = r^2.

The upper bound of z is 2, so we have:

z = 2.

The lower bound of z is 1, so we have:

z = 1.

The total fuel consumption from 6 AM to 1 PM is approximately 39.48 barrels.

To find the average rate of consumption from 6 AM to 1 PM, we need to calculate the total fuel consumption during that time period and divide it by the duration.

The given formula for fuel consumption is f(t) = 0.4t^2 - 0.16t + 21, where t represents the time in hours after 6 AM.

To determine the total fuel consumption from 6 AM to 1 PM, we need to substitute the values of t for the respective time periods. From 6 AM to 1 PM is a duration of 7 hours.

Substituting t = 7 into the formula, we get:

f(7) =[tex]0.4(7)^2[/tex] - 0.16(7) + 21

     = 0.4(49) - 1.12 + 21

     = 19.6 - 1.12 + 21

     = 39.48 barrels of fuel oil.

Therefore, the total fuel consumption from 6 AM to 1 PM is approximately 39.48 barrels.

To calculate the average rate of consumption, we divide the total fuel consumption by the duration:

Average rate of consumption = Total fuel consumption / Duration

                          = 39.48 barrels / 7 hours

                          ≈ 5.64 barrels per hour.

The new integral becomes:

∫(22√(z^2 + 18)) dz = ∫(22√u) (1/2z) du

the indefinite integral of ∫(22√(z^2 + 18)) dz is (22/3) * (√(z^2 + 18))^3 / z + C, where C is the constant of integration.

What is Integrity?

Integrity is the quality of being honest and having strong moral principles;

moral uprightness.

To evaluate the indefinite integral of ∫(22√(z^2 + 18)) dz, we will proceed by answering the following parts:

(a) What is u and du?

To find u, we choose a part of the expression to substitute. In this case, let u = z^2 + 18.

Now, we differentiate u with respect to z to find du.

Taking the derivative of u = z^2 + 18, we have:

du/dz = 2z

(b) What is the new integral in terms of u?

Now that we have found u and du, we can rewrite the original integral in terms of u.

The new integral becomes:

∫(22√(z^2 + 18)) dz = ∫(22√u) (1/2z) du

(c) Evaluate the new integral.

To evaluate the new integral, we can simplify and integrate the expression in terms of u:

(22/2) ∫(√u) (1/z) du = 11 ∫(√u / z) du

We can now integrate the expression:

11 ∫(√u / z) du = 11 * (2/3) * (√u)^3 / z + C

= (22/3) * (√(z^2 + 18))^3 / z + C

Therefore, the indefinite integral of ∫(22√(z^2 + 18)) dz is (22/3) * (√(z^2 + 18))^3 / z + C, where C is the constant of integration.

Answer:

  x = 11, y = 4

Step-by-step explanation:

You want to find x and y given an inscribed quadrilateral with angles identified as L=(10x), M=(10x-6), N=(16y+6), X=(4+18y).

The key here is that an inscribed angle has half the measure of the arc it subtends. Translated to an inscribed quadrilateral, this has the effect of making opposite angles be supplementary.

This relation gives you two equations in x and y:

Subtracting the first equation from the second gives ...

  (10x +18y -2) -(10x +16y +6) = (180) -(180)

  2y -8 = 0

  y = 4

Using this value of y in the first equation, we have ...

  10x +(16·4 +6) = 180

  10x +70 = 180

  x +7 = 18

  x = 11

The solution is (x, y) = (11, 4).

Additional comment

The angle measures are L = 110°, M = 104°, N = 70°, X = 76°.

The "supplementary angles" relation comes from the fact that the sum of arcs around a circle is 360°. Then the two angles that intercept the major and minor arcs of a circle will have a total measure that is half a circle, or 180°.

For example, angle L intercepts long arc MNX, and opposite angle N intercepts short arc MLX.

The derivative of the function f(z) = 4z² - 3z is 16z - 3.

The formal definition of the derivative of a function f(x) at x = a is:

f'(a) = lim_{h->0} (f(a+h) - f(a)) / h

In this case, we have f(z) = 4z² - 3z. So, we have:

f'(z) = lim_{h->0} (4(z+h)² - 3(z+h) - (4z² - 3z)) / h

f'(z) = lim_{h->0} (16z² + 16zh + 4h² - 3z - 3h - 4z² + 3z) / h

f'(z) = lim_{h->0} (16zh + 4h² - 3h) / h

f'(z) = lim_{h->0} h (16z + 4h - 3) / h

f'(z) = lim_{h->0} 16z + 4h - 3

The limit of a constant is the constant itself, so we have:

f'(z) = 16z + 4(0) - 3

f'(z) = 16z - 3

Therefore, the derivative of the function f(z) = 4z² - 3z is 16z - 3.

The height of the right triangle-shaped house is approximately 41.98 feet

calculated using the Pythagorean theorem with a roof length of 51 feet and a base length of 29 feet.

The height of the right triangle-shaped house can be calculated using the Pythagorean theorem, given the length of the roof (hypotenuse) and the base of the triangle. The height can be determined by finding the square root of the difference between the square of the roof length and the square of the base length.

To calculate the height, we can use the formula:

height = √[tex](roof length^2 - base length^2[/tex])

Plugging in the values, with the roof length of 51 feet and the base length of 29 feet, we can calculate the height as follows:

height = √[tex](51^2 - 29^2)[/tex]

= √(2601 - 841)

To evaluate the definite integral ∫[2²√1-x²] dx from 0 to 1, a change of variables can be used.

Let's introduce the variable u such that u = 1 - x². Taking the derivative of both sides with respect to x gives du/dx = -2x. Solving for dx, we have dx = -(1/2x) du. Substituting this into the integral and changing the limits of integration accordingly, we get ∫[2²√1-x²] dx = ∫[2²√u] (-1/2x) du. Simplifying, we have -1/2 ∫[2²√u] du. This can be further simplified as -1/2 [u^(3/2)/(3/2)] evaluated from 0 to 1. Evaluating this expression yields the final answer.

To simplify the expression sin(t)sec(t) - cos(t)sin(t), we can use trigonometric identities to rewrite it in terms of a single trigonometric function. The simplified expression is tan(t).

We start by factoring out sin(t) from the expression:

sin(t)sec(t) - cos(t)sin(t) = sin(t)(sec(t) - cos(t))

Next, we can use the identity sec(t) = 1/cos(t) to simplify further:

sin(t)(1/cos(t) - cos(t))

To combine the terms, we need a common denominator, which is cos(t):

sin(t)(1 - cos²(t))/cos(t)

Using the Pythagorean Identity sin²(t) + cos²(t) = 1, we can substitute 1 - cos²(t) with sin²(t):

sin(t)(sin²(t)/cos(t))

Finally, we can simplify the expression by using the identity tan(t) = sin(t)/cos(t):

sin(t)(tan(t))

Hence, the simplified expression of sin(t)sec(t) - cos(t)sin(t) is tan(t).

If the midpoint of the interval [1.004, 1.017] is chosen as an approximation for the true value of the definite integral, the midpoint rule estimates the integral value to be between 0.013f(1.0105) and 0.013f(1.0105).

The midpoint rule is a numerical method used to approximate the value of a definite integral. It divides the interval of integration into subintervals and approximates the integral by evaluating the function at the midpoint of each subinterval and multiplying it by the width of the subinterval.

In this case, the interval [1.004, 1.017] has a midpoint at (1.004 + 1.017)/2 = 1.0105. If we choose this midpoint as an approximation for the true value of the definite integral, the midpoint rule estimates the integral value to be the product of the function evaluated at the midpoint and the width of the interval.

Since the lower bound of the interval is 1.004 and the upper bound is 1.017, the width of the interval is 1.017 - 1.004 = 0.013. Therefore, the midpoint rule estimates the integral value to be between f(1.0105)[tex]\times[/tex]0.013, where f(1.0105) represents the value of the function at the midpoint.

However, without additional information about the function or the behavior of the integral, we cannot determine the exact value of the integral or provide a more precise estimate using the midpoint rule.

If f and g are differentiable functions such that f(0) =2, f'(0) = -5,8(0) = – 3, and g'(0)=7, the value of (f/8)'(0) is -17/32.

To find the derivative of f(x)/8, we can use the quotient rule, which states that the derivative of the quotient of two functions is equal to (f'g - fg') / g², where f and g are functions. In this case, f(x) is the given function and g(x) is the constant function g(x) = 8. Using the quotient rule, we differentiate f(x) and g(x) separately and substitute them into the formula.

At x = 0, we evaluate the expression to find the value of (f/8)'(0). Plugging in the given values, we have:

(f/8)'(0) = (8 x f'(0) - f(0)*8') / 8²

Simplifying, we get:

(f/8)'(0) = (8 x (-5) - 2 x (-3)) / 64

(f/8)'(0) = (-40 + 6) / 64

(f/8)'(0) = -34/64

Finally, we can simplify the fraction:

(f/8)'(0) = -17/32

Therefore, the value of (f/8)'(0) is -17/32.
