By the inscribed angle theorem,

[tex]12y-1=9y+11[/tex]

[tex]3y=12[/tex]

[tex]y=4[/tex]

So the angles have measure

[tex](12\cdot4-1)^\circ=\boxed{47^\circ}[/tex]

The measure of the angle is 47 degrees. Thus, the correct option is B.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The angles at the periphery made by the same chord will be equal.

The equation is given as,

12y - 1 = 9y + 11

Simplify the equation, then we have

12y - 1 = 9y + 11

12y - 9y = 11 + 1

3y = 12

y = 4

Then the measure of the angle is given as,

Angle = 12 x 4 - 1

Angle = 48 - 1

Angle = 47

Thus, the correct option is B.

Answer:

$6.48

Step-by-step explanation:

Answer: (3b + 5)(3b - 5)

Because both terms, 9b² and 25, are perfect squares, you can factor by taking the square roots of both terms.

The square root of 9b² is 3b (3b × 3b = 9b²).

The square root of 25 is 5 (5 × 5 = 25).

9b² - 25 has a negative, so the factored expression would be

(3b + 5)(3b - 5). The signs (+ and -) alternate in this case because the  expression, 9b² - 25, has no middle term.

The question involves computing the double surface integral of the curl of the given vector field over a specified surface. The curl of the vector field is found first using a determinantal formula, and the surface integral is then evaluated over the capped cylindrical surface. These concepts are fundamental in vector calculus and have applications in fields such as physics and engineering.

This question requires the application of vector calculus concepts, specifically surface integrals and the divergence theorem. Given the vector field f=(zx+z²y+8y, z³yx+5x, z⁴x²), your task is to compute the double surface integral of the curl of f over a capped cylindrical surface m, which is a union of a cylinder and a hemispherical cap.

To solve it, you will start by finding the curl of the vector field using the determinant of a special kind of 3x3 matrix, called the curl matrix, containing the unit vectors i, j, k, the coefficients of the derivatives in the Cartesian coordinate system, and the components of the vector field. Once you get an expression for the curl of f, you will set up and evaluate a double surface integral over the given region m to find the desired quantity.

The concept of surface integrals is prevalent in many fields including physics and engineering where it is used to calculate quantities like flux. The divergence theorem, also known as Gauss's theorem, connects the flux of a vector field through a closed surface to the divergence of this field in the volume enclosed by the surface.

Title: The Infallible Logic of 1 + 1 = 2

Introduction:

The seemingly simple equation, 1 + 1 = 2, holds a profound and fundamental place in mathematics and logic. Its truth is evident, self-evident, and indisputable, serving as a cornerstone for mathematical reasoning and human understanding. In this essay, we explore the underlying principles and irrefutable logic behind the statement that 1 + 1 equals 2.

Body:

Basic Arithmetic Principles:

At its core, mathematics is a system of rules and principles that govern the manipulation of numbers and quantities. The equation 1 + 1 = 2 is a fundamental expression of these principles. It demonstrates the addition of two individual units (1) to form a collective sum (2). This is a foundational concept in arithmetic.

Axiomatic Truth:

In the realm of mathematics, certain statements are considered axioms—self-evident truths that do not require proof. 1 + 1 = 2 is one of these axioms. It is a statement that is true by definition and serves as a building block for more complex mathematical operations.

Logical Proof:

One way to understand why 1 + 1 equals 2 is through logical proof. We can start with the premise that we have one unit (1) and add another unit (1) to it. The result, by definition, is two units (2). This logical progression is simple and irrefutable.

Set Theory:

In set theory, a branch of mathematics that deals with sets and their relationships, the equation 1 + 1 = 2 is rigorously defined. In set theory, 1 represents a set containing a single element, and adding another set with one element results in a set with two elements. This is a formalized representation of why 1 + 1 equals 2.

Real-World Application:

The equation 1 + 1 = 2 has practical applications in various fields, including science, engineering, economics, and everyday life. It reflects the way we count and aggregate objects, making it essential for quantitative analysis and problem-solving.

Conclusion:

The equation 1 + 1 = 2 is not merely a mathematical expression; it is a reflection of the logical and axiomatic foundation upon which mathematics and much of human reasoning are built. Its undeniable truth serves as a testament to the precision and consistency of mathematics. The simple act of adding one to one resulting in two exemplifies the elegance and power of mathematical logic, making it an enduring principle in our understanding of the world. In a universe governed by mathematical laws, 1 + 1 will always equal 2, and this irrefutable truth is a testament to the beauty and reliability of mathematics.

In converting to spherical coordinates, we use

[tex]x=\rho\cos\theta\sin\varphi[/tex]

[tex]y=\rho\sin\theta\sin\varphi[/tex]

[tex]z=\rho\cos\varphi[/tex]

so that

[tex]\mathrm dV=\rho^2\sin\varphi\,\mathrm d\rho\,\mathrm d\theta\,\mathrm d\varphi[/tex]

Then the integral is

[tex]\displaystyle\iiint_Ey^2\,\mathrm dV=\int_0^\pi\int_0^\pi\int_0^3\rho^4\sin^2\theta\sin^3\varphi\,\mathrm d\rho\,\mathrm d\varphi\,\mathrm d\theta=\boxed{\frac{162\pi}5}[/tex]

To evaluate the expression using spherical coordinates, express the given solid hemisphere in spherical coordinates by replacing x, y, and z with r, θ, and φ. Substitute the volume element in spherical coordinates, and integrate over the limits specified by the solid hemisphere. Finally, evaluate the expression numerically.

To evaluate the expression ∫ey2dv using spherical coordinates, we first need to express the solid hemisphere in spherical coordinates. The given condition for the solid hemisphere is x2 + y2 + z2 ≤ 9 and y ≥ 0. In spherical coordinates, the equation for the solid hemisphere becomes r ≤ 3 and 0 ≤ θ ≤ π/2.

The volume element dv in spherical coordinates is dV = r2sinθdrdθdφ. Substituting this into the original expression, we have ∫ey2dv = ∫e(r*sinθcosφ)2r2sinθdrdθdφ. Since we are integrating over the solid hemisphere, the limits of integration for r, θ, and φ are r = 0 to r = 3, θ = 0 to θ = π/2, and φ = 0 to φ = 2π.

After substituting the expressions for y and dv in terms of spherical coordinates and integrating over the given limits, we can find the numerical value of the given expression.

Answer:

The solution is (-3, 10.8)

Step-by-step explanation:

While it's rather obvious that you want to solve this system of linear equations, you should share that instruction when you post the problem.

To solve this system using elimination by addition and subtraction, combine the two equations as shown below (to eliminate y):

-0.18x + y = -6.54

-2.8x - y = -2.4

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

-2.98x = -8.94

Dividing both sides by -2.98, to isolate x, yields:  x = -8.94 / (-2.98) = -3.

Then x = 3.  Find y from -2.8x - y = -2.4:  -2.8x + 2.4 = y, and here,

y = -2.8(-3) + 2.4 = 8.4 + 2.4 = 10.8

Then the solution is (-3, 10.8)

Final answer:

The slope of a line perpendicular to a line with slope 3/4 is -4/3. This follows from the principle that slopes of perpendicular lines are negative reciprocals of each other.

Explanation:

The question pertains to finding the slope of a line that is perpendicular to another line with a given slope. Given that the slope (m) of line l is 3/4, let's find the slope of line m which is perpendicular to l. In algebra, the slope of perpendicular lines are negative reciprocals of each other. This means that to find the slope of m, you take the negative reciprocal of 3/4, which is -4/3.

Thus, the correct answer is C. - 4 over 3.

The expression 6(x − 5) means the product of 6 and the difference of x minus 5. If x = 7, the value of the expression is 12.

We can see that the number 6 to the left of the expression 6(x - 5), this means 6 times (x - 5), The reason we write it that way is because the multiplication symbol, ×, can be confused with the variable x, follow by (x - 5) which is the difference of x minus 5. All together is the product of 6 and the difference of x minus 5.

If x = 7, then:

6(7 - 5) = 6(2) = 12

Following are the solution to the given expression:
