Simplify the expression 12p-8p,4p(3-2)

Answer:

give the diagram please

Answer:

The measure of the missing angle is 37°.

Answer:

p = -4

q = 9

Step-by-step explanation:

The vertex form of a parabola is:

y = a (x − h)² + k

Given that the leading coefficient is 1 and the vertex is (2,5):

y = (x − 2)² + 5

Distributing:

y = x² − 4x + 4 + 5

y = x² − 4x + 9

Alternatively, using calculus, if y = x² + px + q, then the derivative is:

dy/dx = 2x + p

The turning point occurs when the derivative is 0:

0 = 2x + p

0 = 2(2) + p

p = -4

Plugging in and solving for q:

y = x² − 4x + q

5 = (2)² − 4(2) + q

5 = 4 − 8 + q

q = 9

so we know the EQUATion of the line, now let's work out the inequality of it.

the shaded area is the "true" region or area, and the non-shaded is the "false" region, hmmm let's work our way from the "false" region.

first off, the line is solid, that means the line includes values in the inequality, meaning the shaded part extends to the borderline, so the inequality will be either ⩾ or ⩽, let's work it out from the "false" region, by picking out a point there, hmmm let's use say x = 6 and y = -4, so the point is (6 , -4) and let's plug it in the EQUATion.

[tex]y ~~ \square ~~ \cfrac{3}{4}x-3\hspace{5em}(6~~,~-4)\qquad \implies \qquad -4 ~~ \square ~~ \cfrac{3}{4}(6)-3 \\\\\\ -4 ~~ \square ~~ \cfrac{18}{4}-3\implies -4 ~~ \square ~~ \cfrac{9}{2}-3\implies -4 ~~ \square ~~ \cfrac{9-6}{2}\implies -4 ~~ \square ~~ \cfrac{3}{2} \\\\\\ -4 ~~ \square ~~ 1.5\qquad \textit{is -4 greater or less than 1.5?}[/tex]

well, clearly -4 is less than 1.5, however to  make that a false statement, we can say that -4 is more than 15, now, is not true, is "false" and since we're working from the "false" region, that is what we need, "more than", or ⩾

[tex]{\Large \begin{array}{llll} y\geqslant \cfrac{3}{4}x-3 \end{array}}[/tex]

now, bear in mind that we could have started from the "true" region, the shaded one, and pick a point in it like (0 , 0), if you test, that gives us something like 0 [ ] -3, to make that true, we make it 0 ⩾ -3, because that is true, 0 is really greater than -3, and working for the "true" region, that's what we need.

The equations are H = 4x + 60 and P = 8x + 20. We need to rent 10 tables to ensure that the cost of the rental will be the same.

A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A set of equations satisfied by the same set of variables is called a system of linear equations."

Let us suppose tables as x.

Given that,

The happy party rents tables for $4 per table plus a delivery fee of 60. This is expressed as:

H = 4x + 60

Party Rental rents tables for $8 per table plus a $20 delivery fee.

P = 8x + 20

To get the same cost of the rent:

H = P

4x + 60 = 8x + 20

60 - 20 = 8x - 4x

40 = 4x

x = 10

Hence, we need to rent 10 tables to ensure that the cost of the rental will be the same.

In mathematics, the term "discrete" is often used to refer to objects or structures that are distinct and separate, rather than being continuous or flowing. In the context of this course, the term "discrete" is used to describe a particular branch of mathematics known as "discrete mathematics" or "discrete structures."

Discrete mathematics is concerned with mathematical structures that are countable and finite, rather than continuous or infinite. These structures are typically represented by sets, graphs, or other discrete objects, and can be used to model a wide range of phenomena, from computer algorithms to social networks.

One of the key features of discrete structures is that they are composed of individual, separate elements, rather than being continuous or flowing. For example, a set of integers is a discrete structure, because it consists of separate, distinct integers, rather than a continuous range of numbers. Similarly, a graph is a discrete structure, because it consists of separate vertices and edges, rather than a continuous line.

Because of their discrete nature, these structures can be analyzed and manipulated using a range of mathematical tools and techniques, such as combinatorics, graph theory, and probability theory. This makes discrete mathematics a fundamental part of many areas of computer science, engineering, and other fields that rely on mathematical modeling and analysis.

In contrast, continuous structures, such as real numbers or geometric shapes, are often analyzed using calculus or other techniques that deal with the infinite and continuous nature of these objects.

In summary, when we talk about "discrete structures" or "discrete mathematics," we are referring to mathematical objects and structures that are countable, finite, and composed of individual, separate elements. These structures can be analyzed and manipulated using a range of mathematical tools, and are a fundamental part of many areas of computer science, engineering, and other fields that rely on mathematical modeling and analysis.

The relationship between the radius and volume of a cylinder with a height of 4 feet is nonlinear because the volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height. In this case, the height is fixed at 4 feet. As we change the radius, the volume changes in a nonlinear manner.

The volume increases much faster as the radius increases. This can be seen from the exponential nature of the formula, as the radius is squared. Therefore, even a small increase in the radius results in a substantial increase in the volume, making the relationship between radius and volume nonlinear.

In contrast, if the height were to be proportional to the radius, then the relationship between radius and volume would be linear. This is because the volume would be proportional to the product of the radius and height, which is a linear relationship.

Therefore, the nonlinear relationship between radius and volume, in this case, is due to the exponential nature of the formula for the volume of a cylinder and the fixed height of 4 feet.

Considering all the given information, the probability that the subcommittee consists of 3 republicans is 0.0345, or 3.45%.

To find the probability that the subcommittee consists of 3 Republican’s, we first calculate the number of ways to choose 3 Republicans out of 5:

C(5, 3) = 5! / (3! (5 - 3)!)

=5! / (3! 2!)

= (5 ×4 × 3!) / (3 × 2 × 3!)

= (5 × 4) / (2 × 2)

= 10.

The total number of ways to choose 3 members out of a committee of 5 Republicans, 6 Democrats, and 2 Independents is:

C(13, 3) = 13! / (3! (13 - 3)!)

=13! / (3! 10!)

= (13 × 12 × 11 × 10!) / (3 × 2 × 1 × 10!)

= (13 × 12 × 11) / (3 × 2 × 1)

= 286

So the probability of choosing 3 Republicans is:

P(3 Republicans) = 10 / 286 = 1/29

Answer: An isosceles triangle is a triangle with two sides that are congruent (equal in length). If DEF is isosceles with base DF, then DE and EF are congruent and have the same length. This means that the two sides of the triangle are equal in length, and that the angle formed by DE and EF is equal to each other (since they are congruent sides, they must also be congruent angles). The two equal angles are called the base angles of the isosceles triangle.

The expression as product is sin(a)(4 + 2cos(a) - 4sin²(a))

From the question, we have the following parameters that can be used in our computation:

sin(a)+sin(2a)+sin(3a)

By sine rule, we have

sin(a)+sin(2a)+sin(3a) = sin(a) + 2sin(a)cos(a) + sin(3a)

Factor out sin(a)

sin(a)+sin(2a)+sin(3a) = sin(a)(1 + 2cos(a)) + sin(3a)

Expanding sin(3a), we have

sin(a) + sin(2a) + sin(3a) = sin(a)(1 + 2cos(a)) + 3sin(a) - 4sin³(a)

So, we have

sin(a) + sin(2a) + sin(3a) = sin(a)(1 + 2cos(a) + 3 - 4sin²(a))

Evaluate the like terms

sin(a) + sin(2a) + sin(3a) = sin(a)(4 + 2cos(a) - 4sin²(a))

Hence, the product expression is sin(a)(4 + 2cos(a) - 4sin²(a))

Rounding to the nearest tenth, the angular speed of the propeller is 157.1 rad/s.

A radian is a unit of measurement for angles in mathematics. It is defined as the ratio of the length of an arc of a circle to the radius of the circle. In other words, one radian is equal to the angle created at the center of a circle by an arc that is equal in length to the radius of the circle.

Radians are used as a more natural and convenient way to measure angles than degrees, especially in calculus and other branches of mathematics that deal with the study of curves and functions. For example, the trigonometric functions (sine, cosine, and tangent) are defined in terms of radians, and the derivatives of these functions are easier to work with in radians than in degrees

To convert from revolutions per minute to radians per second, we need to divide by the number of minutes in one hour and multiply by the number of radians in one revolution. We can write this conversion as:

4700 rev/min * (2π rad/rev) / (60 min/hr) = w rad/s

where w denotes the angle's rotational speed in radians per second. Plugging in the conversion factor for one revolution, we get:

w = 4700 rev/min * (2π rad/rev) / (60 min/hr) = (4700 * 2π) / 60 = 157.07 rad/s

The length of the midsegment of the trapezoid is 81 units.

The midsegment of a trapezoid is the line segment connecting the midpoints of the two non-parallel sides of a trapezoid.

The length of the midsegment of a trapezium is half the sum of the top and bottom of the trapezoid.

Therefore, let's find LM, the midsegment of the trapezoid.

Hence,

LM = 1 / 2 (AB + DC)

AB = 34

DC = 128

LM = 1 / 2 (34 + 128)

This can be solved using the concept of triangle similarity.

Triangulus, which means "three-cornered" or "having three angles," is a Latin word with roots in tri-, "three," and angulus, "angle or corner." Three vertices make up a triangle, a three-sided polygon. The triangle's angles are formed at a point where the three sides are joined end to end. The summation of the triangle's three angles equals 180 degrees. Triangles can be classified as equilateral, isosceles, or scalene depending on how long their sides are.

Consider, the triangle ABC and the mid-segment line becomes CD.

Now, from similarity

Δ DBA ≅ Δ ABC

AB² = BC. BD ............... (i)

Step-by-step explanation:

Here are the steps to write the polynomial -15y + 12y² - 9y as a product of polynomials in standard form:

Factor out the coefficient of the linear term: -15y = -15 * y

Factor out the coefficient of the quadratic term: 12y² = 12 * y^2

Add the two factored polynomials: -15 * y + 12 * y^2 - 9 * y

Simplify the expression: (-15 * y + 9 * y) + 12 * y^2 = -6 * y + 12 * y^2

The existence, uniqueness, and minimum radius of convergence of a Taylor series expansion about a point depend on the function being expanded. In general, there is no guarantee that a Taylor series will exist or be unique for every function.

A Taylor series expansion of a function about a point is a representation of the function as an infinite sum of terms involving powers of the difference between the independent variable and the point. If the function is well-behaved near the point, its Taylor series will converge to the function within some interval around the point. The smallest such interval is called the radius of convergence.

If the function is infinitely differentiable (i.e. has derivatives of all orders) near the point, its Taylor series will converge to the function within the entire interval of convergence. In this case, the solution is said to be unique. However, if the function is not infinitely differentiable, it may not be possible to find a Taylor series that converges to the function, or there may be multiple Taylor series that converge to the function within different intervals.

The minimum radius of convergence of a Taylor series is difficult to determine in general, as it depends on the behavior of the function at infinity. In some cases, the radius of convergence can be estimated using techniques such as Cauchy-Hadamard theorem. However, in general, determining the exact radius of convergence requires knowledge of the behavior of the function at all points, not just near the point of expansion.
