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

And there you have it, the polynomial -15y + 12y² - 9y can be written as a product of two polynomials in standard form, -6 * y + 12 * y^2.

Answer:

Let's call the initial fee "x". The equation for the total cost of using a computer for t minutes at the internet cafe can be expressed as:

C = x + 0.60t

Knowing that the total charge to use a computer for 5 minutes would be $6, we can use this information to find the value of x:

C = x + 0.60 * 5

6 = x + 3

x = 6 - 3

x = 3

So, the equation representing the total cost of using a computer for t minutes at the internet cafe is:

C = 3 + 0.60t

The value of q = 25.96

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)

Δ ADB ≅ Δ ABC

AD² = BD. CD ............. (ii)

thus, Δ ADC ≈ Δ ABC

AC² = BC. CD

Thus, q² = (17.5 + 21) × (17.5)

or, q² = 673.75

or, q = 25.96

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

Therefore the probability of the subcommittee consisting of 3 Republicans is approximately 0.0345, or 3.45%.

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))

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.

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 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)

LM = 1 / 2 (162)

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

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.

Answer:

Step-by-step explanation:

σ = sqrt [ Σ ( xi - μ )^2 / N ]

where:

σ is the standard deviation

Σ is the sum of the values

xi is the value of the i-th observation

μ is the mean of the population

N is the number of observations

First, we need to find the mean of the population:

μ = (20 + 30 + 13 + 10 + 22 + 37) / 6

μ = 132 / 6

μ = 22

Next, we can calculate the deviations of each observation from the mean:

20 - 22 = -2

30 - 22 = 8

13 - 22 = -9

10 - 22 = -12

22 - 22 = 0

37 - 22 = 15

Then, we square each deviation:

(-2)^2 = 4

8^2 = 64

(-9)^2 = 81

(-12)^2 = 144

0^2 = 0

15^2 = 225

We add up the squared deviations:

4 + 64 + 81 + 144 + 0 + 225 = 518

We divide by the number of observations and take the square root:

σ = sqrt [ Σ ( xi - μ )^2 / N ]

σ = sqrt (518 / 6)

σ ≈ 10.72

Therefore, the standard deviation of the population is approximately 10.72 dollars.

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
