Answer:

8 and 4

Step-by-step explanation:

let the 2 numbers be a nd b

equations :

a + b = 12

a - b = 4

Adding the two equations

a + b + a - b = 12 + 4

2a= 16

a = 8

b = 4

The moment about the x-axis is s = (2λ/9√3) (\(15^{3/2}\)), where s represents the numerical value of the moment rounded to the nearest tenth.

To find the moment about the x-axis, we need to integrate the product of the density and the distance from each infinitesimally small segment of the wire to the x-axis.

The wire lies along the curve y = √3x from x=0 to x = 5. The linear density of the wire is constant, so we can treat it as a constant factor in the integral.

Let's consider an infinitesimally small segment of the wire with length ds at a distance y from the x-axis. The mass dm of this segment can be expressed as dm = λds, where λ is the linear density of the wire.

Since the wire lies along the curve y = √3x, the distance from each segment to the x-axis is y = √3x.

Now, we can express the moment Mx about the x-axis as the integral of the product of the density and the distance:

Mx = ∫(0 to 5) y λ ds

Since λ is constant, it can be taken outside the integral:

Mx = λ ∫(0 to 5) y ds

To express y in terms of x and ds in terms of dx, we can rewrite the equation y = √3x as x = \(y^{2/3}\).

Taking the derivative with respect to x, we have dx = 2y/3 dy.

Substituting these values into the integral, we get:

Mx = λ ∫(0 to √15) (√3x)(2y/3) dy

Simplifying the expression, we have:

Mx = (2λ/3√3) ∫(0 to √15) y² dy

Integrating y² with respect to y, we get:

Mx = (2λ/3√3) [(y³/3)] (0 to √15)

Simplifying further, we have:

Mx = (2λ/9√3) (\(15^{3/2}\) - 0³)

The moment about the x-axis is given by Mx = (2λ/9√3) (\(15^{3/2}\)), where λ is the linear density of the wire.

Since the problem states that the wire has constant density, we can replace λ with a constant value.

After 14 days, you will have approximately $2.4414 invested in the stock market.

The amount you will have invested after 14 days can be calculated using the geometric sequence formula. The formula for the nth term of a geometric sequence is given by:

an = a1 x \(r^{(n-1)\)

Where:

an is the nth term,

a1 is the first term,

r is the common ratio, and

n is the number of terms.

In this case, the initial investment is $20,000, and each day the investment loses half of its value, which means the common ratio (r) is 1/2. We want to find the value after 14 days, so n = 14.

Substituting the given values into the formula, we have:

a14 = 20000 x\((1/2)^{(14-1)\)

a14 = 20000 x \((1/2)^{13\)

a14 = 20000 x (1/8192)

a14 ≈ 2.4414

Therefore, after 14 days, you will have approximately $2.4414 invested in the stock market.

Step-by-step explanation:

Solve for n:

I start to fall asleep if I read a math book. This can be rewritten as: "if I read a math book then I start to fall asleep". And this is p⇒q.

I drink soda whenever I start to fall asleep. This can be rewritten as:"if I start to fall asleep then I drink soda" . And this is q⇒r.

The graph of the quadratic function y = 1.5x² + 4x - 2 is given by the image shown at the end of the answer.

To obtain the graph of a quadratic function, these three features have to be obtained from the function's definition:

- The x-intercepts, which are the roots of the function.

- The y-intercept, which is the value of y when the function crosses the y-axis.

- The vertex, which is the turning point of the function.

- The function for this problem is defined as follows:

y = 1.5x² + 4x - 2.

Hence the numeric values of the coefficients are listed as follows:

a = 1.5, b = 4, c = -2.

Inserting these coefficients into a calculator, the x-intercepts of the function are given as follows:

x = -3.09  -> hence the function passes through point (-3.09, 0).

x = 0.43 -> hence the function passes through point (0.43, 0).

The y-intercept of the function is given by coefficient c = -2, hence the function also passes through point (0, -2).

The x-coordinate of the vertex is given as follows:

x = -b/2a = -4/3 = -1.33.

Hence the y-coordinate of the vertex is:

y = 1.5(-1.33)² + 4(-1.33) - 2 = -4.67.

Answer:

a. The possible dimensions of the total area are;

The width of the total area is (2·x + 8) inches

The length of the total area is (2·x + 10) inches

b. The dimensions of the photos are as follows;

The length of the photos are 10 inches

The width of the photos are 8 inches

Step-by-step explanation:

a. Given that the area, A = 4·x² + 36·x + 80

We get;

A = 4 × (x² + 9·x + 20) = 4 × (x + 4) × (x + 5) = (2·x + 8)·(2·x + 10)

Therefore, the possible dimensions of the total area (photo + mat) are;

The width of the total area (photo + mat) = (2·x + 8) in.

The length of the total area (photo + mat) = (2·x + 10) in.

b. The dimensions of the photos alone are shorter than the dimensions of the photo and mat combined by 2·x each

Therefore, we have the dimensions of the photos are as follows;

The length of the photo = (2·x + 10) in. - 2·x in. = 10 in.

The width of the photos = (2·x + 8) in. - 2·x in. = 8 in.

The dimensions of the document using the given scales are:

1/2 scale: 10 inches by 17 inches

The dimensions of the document using the given scales are:

1/2 scale: 10 inches by 17 inches
3/4 scale: 15 inches by 25.5 inches
1 scale: 20 inches by 34 inches
1 and 1/2 scale: 30 inches by 51 inches.

To find the dimensions of the document using the given scales, we need to multiply the original dimensions by the scale factor.

For a scale of 1/4, we multiply the original dimensions (20 inches by 34 inches) by 1/4.
So, the dimensions would be (20 * 1/4) inches by (34 * 1/4) inches, which simplifies to 5 inches by 8.5 inches.

For a scale of 1/2, we multiply the original dimensions by 1/2.
So, the dimensions would be (20 * 1/2) inches by (34 * 1/2) inches, which simplifies to 10 inches by 17 inches.

In contrast to quantitative research, sampling may not always produce the same results in qualitative data analysis.  The analysis will depend on the more complicated themes.

The researcher must seek for saturation in order to set a sample size restriction. The ideal in qualitative research is saturation. It serves as a tool to make sure sufficient, high-quality data are gathered to support the investigation.

Quantitative research is a method of gathering and analyzing data that uses numerical and statistical techniques. It is a systematic and objective approach that involves the collection of numerical data through surveys, experiments, or other forms of measurement, which is then analyzed using statistical tools. The goal of quantitative research is to generate and test theories, hypotheses, and models that can be generalized to a larger population.

Quantitative research often involves the use of large samples, which allow researchers to draw statistically significant conclusions about the population being studied. It also involves the use of standardized measures and data collection methods to ensure that the data collected is reliable and valid. Quantitative research is widely used in fields such as social sciences, education, psychology, and market research to study a variety of phenomena, including attitudes, behaviors, opinions, and trends.

Using the limit definition of partial derivatives, we can find fx(x,y) and fy(x,y) for the function f(x,y) = xy. The partial derivative with respect to x, fx(x,y), is equal to y, and the partial derivative with respect to y, fy(x,y), is equal to x.

The partial derivative of a function with respect to one of its variables is the rate at which the function changes when that variable is changed, while holding all other variables constant. In the case of f(x,y) = xy, we can use the limit definition of partial derivatives to find fx(x,y) and fy(x,y). To find fx(x,y), we first fix the value of y and let x approach a small increment h. Then, we take the limit as h approaches zero:

fx(x,y) = lim (h -> 0) [f(x+h,y) - f(x,y)] / h

= lim (h -> 0) [(x+h)y - xy] / h

= lim (h -> 0) hy / h

= y

Similarly, to find fy(x,y), we fix the value of x and let y approach a small increment k. Then, we take the limit as k approaches zero:

fy(x,y) = lim (k -> 0) [f(x,y+k) - f(x,y)] / k

= lim (k -> 0) [x(y+k) - xy] / k

= lim (k -> 0) xk / k

= x

Therefore, the partial derivative with respect to x, fx(x,y), is equal to y, and the partial derivative with respect to y, fy(x,y), is equal to x.
