The positive factors of 100 are 1,2,4,5,10,20,25,50,100.

In mathematics, a factor is a divisor of a given integer that divides it fully without leaving any remainder. We can use numerous methods to find the factors of a number, such as the division method and the multiplication approach.

In real life, we employ factors to split anything into equal rows and columns, compare prices, exchange money, and so on. We can use the division and multiplication methods to get the factors of a number.  

A number's factors can be good or negative. Consider the components of 8. Because 8 is divisible by 1, 2, 4, and 8, the positive factors of 8 are 1, 2, 4, and 8.

The factors of 100 are ,2,4,5,10,20,25,50,100 as they all divide the number 100 without leaving any remainder.

When the shape being rotated has a hole or an empty region, we use slicing of washers to find the volume. If the shape is solid and without any holes, we use slicing of disks.

The volume of a cylindrical disk =

The term "cylindrical disk" is not commonly used in mathematics. Instead, we usually refer to a disk as a two-dimensional shape, while a cylinder refers to a three-dimensional shape.

Volume of a Cylinder:

A cylinder is a three-dimensional shape with two parallel circular bases connected by a curved surface.

To find the volume of a cylinder, we use the formula:

V = πr²h,

where V represents the volume, r is the radius of the circular base, and h is the height of the cylinder.

Volume of a Disk:

A disk, on the other hand, is a two-dimensional shape that represents a perfect circle.

Since a disk does not have height or thickness, it does not have a volume. Instead, we can find the area of a disk using the formula:

A = πr²,

where A represents the area and r is the radius of the disk.

The volume of a solid of revolution =

When finding the volume of a solid of revolution, we typically rotate a two-dimensional shape around an axis, creating a three-dimensional object. Slicing is a method used to calculate the volume of such solids.

To find the volume of a solid of revolution using slicing, we divide the shape into thin slices or disks perpendicular to the axis of revolution. These disks can be visualized as infinitely thin cylinders.

By summing the volumes of these disks, we approximate the total volume of the solid.

The volume of each individual disk can be calculated using the formula mentioned earlier: V = πr²h.

Here, the radius (r) of each disk is determined by the distance of the slice from the axis of revolution, and the height (h) is the thickness of the slice.

By summing the volumes of all the thin disks or slices, we can obtain an approximation of the total volume of the solid of revolution.

As we make the slices thinner and increase their number, the approximation becomes more accurate.

Now, let's address the question of why we might need to use the slicing of washers versus disks.

When calculating the volume of a solid of revolution, we use either disks or washers depending on the shape being rotated. If the shape has a hole or empty region within it, we use washers instead of disks.

Washers are obtained by slicing a shape with a hole, such as a washer or a donut, into thin slices that are perpendicular to the axis of revolution. Each slice resembles a cylindrical ring or annulus. The volume of a washer can be calculated using the formula:

V = π(R² - r²)h,

where R and r represent the outer and inner radii of the washer, respectively, and h is the thickness of the slice.

By summing the volumes of these washers, we can calculate the total volume of the solid of revolution.

Answer:

La superficie de mocano cabe 967.044 veces en la superficie de Mexico.  

Step-by-step explanation:

Primero debemos convertir la unidad de la superficie (S) de mocano (m):

\( S_{m} = 202.7 ha*\frac{10000 m^{2}}{1 ha} = 2.027 \cdot 10^{6} m^{2} \)

Ahora podemos calcular cuantas veces cabe la superficie de mocano en la de Mexico (M):

\( \frac{S_{M}}{S_{m}} = \frac{1.960198 \cdot 10^{9} m^{2}}{2.027 \cdot 10^{6} m^{2}} = 967.044 \)                                

Si multiplicamos la superficie de mocano por 967.044 nos da la superficie de Mexico:

\( 967.044*2.027\cdot 10^{6} m^{2} = 1960198 m^{2} \)

The specific range depends on the material properties and the energy levels involved.

The minimum and maximum frequencies for the acoustic and optic modes depend on the specific system or material under consideration. However, I can provide some general information.

Acoustic Mode:

The acoustic mode refers to the propagation of sound waves or vibrations in a material. In a solid, the acoustic mode can have different types, such as longitudinal and transverse modes.

The minimum frequency for the acoustic mode is typically determined by the size and physical properties of the material. In general, it can be close to zero for macroscopic objects or materials with low elasticity.

The maximum frequency for the acoustic mode depends on factors such as the speed of sound in the material and the characteristic dimensions of the system. It can range from a few kilohertz to several gigahertz.

Optic Mode:

The optic mode is related to the interaction of light with a material. It typically refers to the vibrations of charged particles (such as electrons) in a solid or the oscillations of electric or magnetic fields associated with photons.

The minimum frequency for the optic mode is typically determined by the energy gap between electronic states in the material. For example, in a semiconductor, the minimum frequency is usually in the infrared range.

The maximum frequency for the optic mode is not strictly defined, as it can extend into the terahertz, infrared, visible, ultraviolet, X-ray, and even gamma-ray regions. The specific range depends on the material properties and the energy levels involved.

It's important to note that these frequency ranges are general guidelines and can vary depending on the specific system or material being studied.

Answer:

5.5 = AB

Step-by-step explanation:

take 62 degree as reference angle

using cos rule

cos 62 = adjacent / hypotenuse

0.46 = AB / 12

0.46*12 = AB

5.52 = AB

5.5 = AB

The length of side AB in the given right angle triangle of hypotenuse  12 cm is  5.7 cm.

A triangle with one angle at \(90^o\) is called right angle triangle.

Given that:

Hypotenuse = 12 cm

\(\theta = 62^o\)

The length of side AB in the given right angle triangle is calculated as:

Using trigonometric function,

\(\cos\theta = \dfrac{base}{hypotenuse}\)

Let, the value of base be x

Substitute the values in the given formula:

\(\cos 62^o = \dfrac{x}{12}\)

Using the trigonometric table, the value of \(\cos 62^o\) is 0.4694

\(0.4694 \times 12\)= x

x= 5.6328

x = 5.7

Thus, the length of side AB to 1 decimal place is 5.7 cm

It will take the company 20.3 years to have a financial worth of $11.4

The estimate of profit is given as;

Profit = $0.6 million per year

This means that the engineers based their estimate per year

Hence, the unit of time is year

To do this, we make use of any variable of our choice.

In this case, we let x represents the variable of the amount of time.

In (a), we have:

Profit = $0.6 million per year

So, the expected financial status is 0.6x

This is the amount taken as loan by the engineers.

So, the financial status at the beginning is 1.8

Using the expressions above, we have the yearly worth to be:

y = 0.6x - 1.8

When the financial status is $11.4 million, we have:

0.6x - 1.8 = 11.4

Evaluate the like terms

0.6x = 12.2

Divide both sides by 0.6

The test statistic for testing the hypotheses H0: μ=100 vs Ha: μ<100 using the given sample results x = 91.7, s= 12.5 with n = 30 is -2.17 and the p-value is 0.019. We can reject the null hypothesis H0: μ=100 in favor of the alternative hypothesis Ha: μ<100 at a 5% level of significance.

(a) The test statistic for testing the hypotheses H0: μ=100 vs Ha: μ<100 using the given sample results x = 91.7, s= 12.5 with n = 30 can be calculated as:

t = (x - μ) / (s / sqrt(n))
= (91.7 - 100) / (12.5 / sqrt(30))
= -2.17 (rounded to two decimal places)

Using a t-table with 29 degrees of freedom (n - 1 = 30 - 1 = 29) and a 5% significance level (or 0.05), the corresponding p-value for a one-tailed test is found to be 0.019 (rounded to three decimal places). Therefore, the p-value for the given test statistic is 0.019.

(b) Since the p-value (0.019) is less than the significance level (0.05), we can reject the null hypothesis H0: μ=100 in favor of the alternative hypothesis Ha: μ<100. This implies that there is sufficient evidence to conclude that the population means μ is less than 100 at a 5% level of significance.

(-1,1) because -1 and 1 are not inclusive

Step-by-step explanation:

from x = -1 to x = 1, the y-value keeps decreasing from 4 to 2

there is another one, (3,5)

Therefore, After 20 minutes, there are approximately 11.9 kg (rounded to one decimal place) of salt in the tank.

To solve this problem, we need to consider the rate of change of the amount of salt in the tank over time.

(a) Let's denote the amount of salt in the tank after t minutes as y (in kg). We can set up a differential equation to represent the rate of change of salt:

dy/dt = (rate of salt in) - (rate of salt out)

The rate of salt in is given by the concentration of salt in the incoming water (0 kg/L) multiplied by the rate at which water enters the tank (90 L/min). Therefore, the rate of salt in is 0 kg/L * 90 L/min = 0 kg/min.

The rate of salt out is given by the concentration of salt in the tank (y kg/9000 L) multiplied by the rate at which water leaves the tank (90 L/min). Therefore, the rate of salt out is (y/9000) kg/min.

Setting up the differential equation:

dy/dt = 0 - (y/9000)

dy/dt + (1/9000)y = 0

This is a first-order linear homogeneous differential equation. We can solve it by separation of variables:

dy/y = -(1/9000)dt

Integrating both sides:

ln|y| = -(1/9000)t + C

Solving for y:

y = Ce^(-t/9000)

To find the particular solution, we need an initial condition. We know that at t = 0, y = 12 kg (the initial amount of salt in the tank). Substituting these values into the equation:

12 = Ce^(0/9000)

12 = Ce^0

12 = C

Therefore, the particular solution is:

y = 12e^(-t/9000)

(b) To find the amount of salt in the tank after 20 minutes, we substitute t = 20 into the particular solution:

y = 12e^(-20/9000)

y ≈ 11.8767 kg (rounded to one decimal place)

Step-by-step explanation:

The speed of the faster cyclist is 14\ miles/hr.

What is speed?

It is the average distance coverd in unit time. It is also defined as the rate of change of distance with respect to time.

Since the speed of the first cyclist is double than the second cyclist hence, the first cyclist will cover the double distance than the second cyclist. Consider the first cyclist covers 2s distance and first cyclist covers s distance. The sum of these two distances should be 42 miles. Hence,

\(2s+s=42\\3s=42\\s=14\)

Now, distance coverd by the first cyclist is \(2s=2\times 14\\=28 \ $miles\).

Now, both the cyclists meet after 2 hr hence, time taken by the first cyclist is 2 hr.

\(Speed=\frac{Total\ distance}{Total\ time}\\=28\ miles/2 \ hr\\=14\ miles/hr\)

Hence, the speed of the faster cyclist is 14\ miles/hr.

This is not a fair game because the probability of Arthur winning is not equal to the probability of Gwen winning. To determine if a game is fair, we need to compare the probabilities of each possible outcome.

In this game, there are two possible outcomes: either the marbles match, and Arthur wins, or the marbles do not match, and Gwen wins. Let's consider each case separately.

Case 1: The marbles match (both black or both white).

The probability of drawing a black marble and then drawing another black marble (or drawing a white marble and then drawing another white marble) is (1/2) * (1/2) = 1/4. Therefore, the probability of Arthur winning is 1/4.

Case 2: The marbles do not match (one black and one white).

The probability of drawing a black marble and then drawing a white marble (or drawing a white marble and then drawing a black marble) is (1/2) * (1/2) = 1/4. Therefore, the probability of Gwen winning is 1/4.

Since the probability of Arthur winning is 1/4 and the probability of Gwen winning is 1/4, the game is not fair. In a fair game, the probabilities of each outcome should be equal

To determine if a function crosses the horizontal asymptote, analyse the behavior of the function as it approaches the asymptote and on either side of it.

1. Identify the horizontal asymptote of the function. The horizontal asymptote is a horizontal line that the function approaches as the independent variable (usually denoted as x) goes to positive or negative infinity. It is often denoted by a horizontal line y = a, where "a" is a constant.

2. Examine the behavior of the function as x approaches positive infinity. Evaluate the limit of the function as x goes to positive infinity. If the limit is equal to the value of the horizontal asymptote, then the function does not cross the asymptote. However, if the limit does not equal the asymptote, move to the next step.

3. Examine the behavior of the function as x approaches negative infinity. Evaluate the limit of the function as x goes to negative infinity. If the limit is equal to the value of the horizontal asymptote, then the function does not cross the asymptote. If the limit does not equal the asymptote, proceed to the next step.

4. Investigate the behavior of the function around critical points or points where the function changes its behavior. These points may include the x-intercepts or vertical asymptotes. Determine if the function crosses the asymptote around these points by analyzing the behavior of the function in their vicinity.

If, at any point in this process, the function crosses the horizontal asymptote, then it does not have a true horizontal asymptote. However, if the function approaches the asymptote and does not cross it at any point, then it has a horizontal asymptote.

It's important to note that some functions may have multiple horizontal asymptotes or no horizontal asymptote at all. The steps outlined above are a general guideline, but the specific behavior of the function needs to be analyzed to make a conclusive determination.

To find the new car price after a 6% increase, we can use a linear equation. We start with the original price of $31,800 and calculate the increase amount by multiplying it by 6%.

Let’s assume the new car price is represented by “x” dollars.

We know that the original price was $31,800, and it was increased by 6%.

To calculate the increase amount, we multiply the original price by 6%:

Increase amount = 0.06 * $31,800 = $1,908

The increase amount represents the additional cost added to the original price.

To find the new car price, we add the increase amount to the original price:

New car price = $31,800 + $1,908 = $33,708

Therefore, the new car price after a 6% increase is $33,708.

To determine if there is any association between Age and Opinion on the legality of abortion, a hypothesis test can be conducted at a 5% significance level. The goal is to assess whether the Opinion depends on Age.

In order to test the association between Age and Opinion on the legality of abortion, a chi-square test of independence can be performed. This test helps determine if there is a significant relationship between two categorical variables.

The null hypothesis (H₀) assumes that there is no association between Age and Opinion, meaning the variables are independent. The alternative hypothesis (H₁) assumes that there is an association between the variables.

The chi-square test calculates the expected frequencies under the assumption of independence and compares them to the observed frequencies. If the calculated chi-square statistic exceeds the critical value at the chosen significance level (5% in this case), we reject the null hypothesis and conclude that there is evidence of an association between Age and Opinion.

By performing the chi-square test and comparing the calculated chi-square statistic to the critical value, we can make a conclusion about whether the Opinion on the legality of abortion depends on Age.
