The iterated integral by changing to cylindrical coordinates 2 −2 4 −4 √16 − x2 (x2 y2)3/2 dy dx dz −√16 − x2 is 128π.

To evaluate the iterated integral using cylindrical coordinates, first, we need to change the given rectangular coordinates (x, y, z) to cylindrical coordinates (ρ, φ, z). In cylindrical coordinates, x = ρcosφ, y = ρsinφ, and z = z. The Jacobian for the transformation is |J| = ρ. The given integral can be rewritten as:

∫(φ=0 to 2π) ∫(ρ=0 to 4) ∫(z=-√16-ρ² to √16-ρ²) (ρ²)³/2 * ρ dz dρ dφ

Now, we can evaluate the integral step by step:

1. Integrate with respect to z:

∫(φ=0 to 2π) ∫(ρ=0 to 4) [(z * ρ³) | (z = -√16-ρ²) to (z = √16-ρ²)] dρ dφ

2. Integrate with respect to ρ:

∫(φ=0 to 2π) [(1/4 * ρ⁴) | (ρ = 0) to (ρ = 4)] dφ

3. Integrate with respect to φ:

[(1/4 * 4⁴) * (φ | φ=0 to 2π)] = (256/4) * 2π = 128π

So the value of the iterated integral in cylindrical coordinates is 128π.

Answer:

  C: 2 and 3 only.

Step-by-step explanation:

We know the sum or difference of two odd numbers is even, eliminating choices (1) and (4).

The product of two odd numbers is odd, so (2) is one of the true statements.

__

Let x/y = k, where x and y are both odd. Then x = ky. If k is even, then x is even, a contradiction. So, k must be odd. The integer ratio of two odd numbers is odd, so (3) is one of the true statements.

Only statements (2) and (3) are true.

Step-by-step explanation:

I think-

They can pick 1.29 liters of berries in 1 minute working together.

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

The together rate is the sum of each separate rate. In this question:

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

Together, they can pick x liters, and the rate is: \(\frac{1}{x}\)

Then

\(\frac{1}{x} = \frac{3}{8} + \frac{4}{10}\)

The scale factor of the model car is 1:61.23.

To determine the scale factor, we need to compare the length of the actual car to the length of the model car. The length of the actual car is given as 16 3/4 feet, which can be converted to inches as (16 x 12) + 3 = 195 inches. The length of the model car is given as 3 1/4 inches.

To find the scale factor, we divide the length of the actual car by the length of the model car: 195 inches ÷ 3.25 inches = 60. In the scale factor notation, the first number represents the actual car, and the second number represents the model car. Therefore, the scale factor of the model car is 1:61.23.

There are 1,757,440 feet in 333 miles based on the given double number line.

To determine how many feet are in 333 miles based on the given double number line, we need to find the corresponding point on the "Feet" line that corresponds to 333 miles on the "Miles" line.

From the information provided, we can see that the tick marks on the "Miles" line are evenly spaced. Since there are two tick marks between 0 and 2 miles, each tick mark represents a distance of 2/2 = 1 mile.

Similarly, on the "Feet" line, there are two tick marks between 0 and 10,560 feet. Therefore, each tick mark represents a distance of 10,560/2 = 5,280 feet.

To find the number of feet in 333 miles, we can use the ratio between miles and feet. Since each tick mark on the "Miles" line represents 1 mile and each tick mark on the "Feet" line represents 5,280 feet, we can set up a proportion:

1 mile / 5,280 feet = 333 miles / x feet

Simplifying the proportion, we get:

1/5280 = 333/x

Cross-multiplying, we have:

x = 333 * 5280

Calculating the product, we find:

x = 1,757,440 feet

Therefore, there are 1,757,440 feet in 333 miles based on the given double number line.

To solve a proportion like x/a = b/c, you need to find the value of x that makes the two ratios equal. You can do this by cross-multiplying, which involves multiplying the numerator of one ratio by the denominator of the other ratio, and vice versa. We start by multiplying both sides by ac, giving us x = (ab)/c.

In summary, to solve a proportion of this form in just three steps, we multiply both sides by the product of the denominators, then simplify the resulting expression to get the value of x. To solve a proportion like x/a = b/c, you need to find the value of x that makes the two ratios equal. You can do this by cross-multiplying, which involves multiplying the numerator of one ratio by the denominator of the other ratio, and vice versa.

Following the cross-multiplying method, you multiply the two numbers that are diagonally opposite each other, then do the same for the remaining two numbers. In this case, multiply 'a' by 'c' and 'x' by 'b'. This results in the equation: x * b = a * c. To find the value of x, divide both sides of the equation by 'b'. This will give you the final equation: x = (a * c) / b. By plugging in the values for a, b, and c, you can easily solve for x and find the value that satisfies the proportion x/a = b/c.

The value of the integral is \(-(16/41) e^{(4\theta) }cos(5\theta) + c\)

To evaluate the integral ∫ \(e^{(4\theta)}\) sin(5θ) dθ, we can use integration by parts.

Let's assign u = sin(5θ) and dv = \(e^{(4\theta)}\) dθ.

Differentiating u with respect to θ, we have du = 5 cos(5θ) dθ.

Integrating dv with respect to θ, we have v = (1/4) \(e^{(4\theta)}\).

Now, we can use the integration by parts formula:

∫ u dv = uv - ∫ v du

Applying the formula, we have:

∫ \(e^{(4\theta)}\) sin(5θ) dθ = - (1/4) \(e^{(4\theta)}\) cos(5θ) - ∫ (1/4) \(e^{(4\theta)}\) (5 cos(5θ)) dθ

Simplifying further:

∫\(e^{(4\theta)}\) sin(5θ) dθ = - (1/4) \(e^{(4\theta)}\)cos(5θ) - (5/4) ∫\(e^{(4\theta)}\) cos(5θ) dθ

Now, we have a new integral to evaluate: ∫\(e^{(4\theta)}\)cos(5θ) dθ.

Using integration by parts again with u = cos(5θ) and dv = \(e^{(4\theta)}\)dθ, we obtain:

du = -5 sin(5θ) dθ

v = (1/4) \(e^{(4\theta)}\)

Applying the integration by parts formula:

∫ \(e^{(4\theta)}\)cos(5θ) dθ = (1/4) \(e^{(4\theta)}\)cos(5θ) - (5/4) ∫\(e^{(4\theta)}\) sin(5θ) dθ

Substituting this back into the previous equation, we have:

∫\(e^{(4\theta)}\)sin(5θ) dθ = - (1/4)\(e^{(4\theta)}\) cos(5θ) - (5/4) [(1/4) \(e^{(4\theta)}\) cos(5θ) - (5/4) ∫ \(e^{(4\theta)}\)sin(5θ) dθ]

Now, let's solve for the remaining integral:

(1 + (25/16)) ∫\(e^{(4\theta)}\)sin(5θ) dθ = - (1/4)\(e^{(4\theta)}\) cos(5θ)

Simplifying:

(41/16) ∫ \(e^{(4\theta)}\) sin(5θ) dθ = - (1/4) \(e^{(4\theta)}\)cos(5θ)

Finally, dividing both sides by (41/16), we get:

∫\(e^{(4\theta)}\)sin(5θ) dθ = - (16/41)\(e^{(4\theta)}\) cos(5θ) + c

Therefore, the value of the integral ∫\(e^{(4\theta)}\)sin(5θ) dθ is -(16/41) \(e^{(4\theta)}\) cos(5θ) + c, where c is the constant of integration.

The required volume of the right circular cone is 135.83409in³.

A right circular cone is one whose axis is the line between the vertex and the circular base's midway.

In other words, a right angle is formed when the center point of the circular base and the cone's peak are united.

So, the right circular cone volume formula:

V=1/3hπr²

Diameter = 8.8 in

Radius = 8.8/2 = 4.4 in
Now, calculate the volume as follows:

V = 1/3hπr²

V = 1/3(6.7)π(4.4)²

V = 135.83409 in³

If the three numbers of a square in the complex plane are \(-19+32i,-5+12i and -22+15i\) , then the fourth complex number \(-2+19i\).

Given \(-19+32i,-5+12i and -22+15i\) are three numbers.

Complex numbers are those numbers which extends the real numbers with an imaginary i. In this \(i^{2}=-1\). Major complex numbers are in the form a+ bi where a and b are real numbers.

let the fourth complex numbers be \(x+yi\). Then according to question;

=\((-22+15i)-(-5+12i)\)

=(cos π/2+i sin π/2) \((x+yi)-(-5+12i)\)

\(-17+3i=-y+12\)\(+(x+5)i\)

Now solving for x and y by equating both sides.

x=-2 and y=29

Put the value of x and y in \(x+yi\)

Z=-2+29i

Hence if the three numbers which forms vertices of a square are \(-19+32i,-5+12i,-22+25i\) then the fourth complex numbers be \(-2+29i\).

Step-by-step explanation:

To show that f is entire, we need to show that it is differentiable everywhere in the complex plane. For z = 0, we have f(z) = 1, which is clearly differentiable with derivative 0.

For z ≠ 0, we can use the power series expansion of sin z and write

sin z = z − z^3/3! + z^5/5! − z^7/7! + …

Dividing by z and taking the limit as z → 0, we get

limz→0 sin z/z = limz→0 (1 − z^2/3! + z^4/5! − z^6/7! + …) = 1

since all the terms in the parentheses approach 1 as z → 0.

Therefore, we have shown that f is differentiable everywhere in the complex plane, and hence is an entire function.

c = \(\frac{1}{10}\)

f= 1500

Step-by-step explanation:

Tenemos la siguiente ecuación

\( C = f+cm\)

Tenemos los siguientes valores para m=15000, c = 3000 y para m = 20000, c=3500. Es decir, tenemos las siguientes ecuaciones

\( 3000=f+c15000, 3500=f+c20000\)

Si restamos la segunda ecuación de la primera, tenemos que

\( 3500-3000 = f-f+(20000c-15000c)\)

Luego

\( 500 = 5000c\)

Entonces \( c = \frac{500}{5000} = \frac{1}{10}\)

Si tomamos la primera ecuación, tenemos que \(3000-\frac{15000}{10} = f\). Es decir,
