The selling price of the 6 dining chairs is $3690

An equation is an expression showing the relationship between two or more numbers and variables. An equation can either be linear, quadratic, cubic and so on depending on the degree.

6 dining chairs together cost $1845.00. The chairs were sold to get a profit of 100%. Let x represent the selling price

The formula needed is:

Profit = [(selling price - cost price)/cost price] * 100%

Hence, substituting:

100% = [(x - 1845]/1845] * 100%

(x - 1845]/1845 = 1

x - 1845 = 1845

x = 3690

The selling price is $3690

The correct option is (C) The geom_jitter() function.

The jitter geom is a convenient shortcut for geom_point(position = "jitter"). It adds a small amount of random variation to the location of each point, and is a useful way of handling overplotting caused by discreteness in smaller datasets.

geom_jitter(mapping = NULL, data = NULL, stat = "identity",

 position = "jitter", ..., width = NULL, height = NULL, na.rm = FALSE,

 show.legend = NA, inherit.aes = TRUE)

Since we want points to be jittered and dodged, we can use geom_point with position_jitterdodge (). Make sure to specify the "group" variable: this graph specifies three potential grouping variables (cluster, region, cd_code), and position_jitterdodge can't tell which two to use unless specified.

The geom_jitter() function creates a scatterplot and then adds a small amount of random noise to each point in the plot to make the points easier to find.

Thus, the correct option is (C) The geom_jitter() function.

The maximum value of the function y=cos x/sin x at x = pi/4 is 1, so the value of m is 1.

The maximum value of the function y=cos x/sin x is when the cos x and sin x terms have the same magnitude. This happens when x=pi/4. In this case, the function reduces to y=cos(pi/4)/sin(pi/4) = 1.

Therefore, the value of m = 1.

The maximum value of the function y=cos x/sin x at x = pi/4 is 1, so the value of m is 1.

The function y=cos x/sin x has a maximum value of 1 when x = pi/4.

The derivative of f(z) = ez/(z − 7) is therefore f'(z) = (ez(z - 6))/(z - 7)^2.

The derivative of f(z) = ez/(z − 7) can be calculated using the quotient rule. The quotient rule states that the derivative of the quotient of two functions is equal to the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the denominator squared. Therefore, the derivative of f(z) = ez/(z − 7) is equal to (ez(z - 7) - (ez)(1))/(z - 7)^2. This simplifies to ez/(z - 7)^2. Therefore, the derivative of f(z) = ez/(z − 7) is equal to ez/(z - 7)^2.

For our purposes, we can substitute in g(z) = ez and h(z) = (z − 7). Then, we can calculate the derivatives of each part. The derivative of g(z) is g'(z) = ez, and the derivative of h(z) is h'(z) = 1. Now, we can plug these values into the Quotient Rule and calculate the derivative of the function f(z) = ez/(z − 7).

f'(z) = (ez(z − 7) - ez(1))/(z − 7)^2

f'(z) = (ez(z - 6))/(z - 7)^2

The sign of δsol for the solution will depend on the concentration of the solute and the temperature.

The sign of δsol for the solution will depend on two main factors: the concentration of the solute and the temperature. If the concentration of the solute is increased, the solute's tendency to dissolve in a solvent will also increase, resulting in a higher solubility. This increase in solubility will cause the sign of δsol to be positive. On the other hand, if the temperature is increased, the solubility of the solute will decrease, resulting in a decrease in the solubility. This decrease in solubility will cause the sign of δsol to be negative. Therefore, the sign of δsol for the solution will depend on the concentrations of the solute and the temperature. If the concentration of the solute is increasing, the sign of δsol will be positive; if the temperature is increasing, the sign of δsol will be negative.

The sum of the series correct to four decimal places is 7.0000

To approximate the sum of the series, we can use the ratio test. The ratio test states that if the limit of the ratio of consecutive terms approaches a number L, then the series converges if |L| < 1 and diverges if |L| > 1.

The nth term of the series is given by

[tex]T_n = (-1)^n (3n)(n!)[/tex]

The consecutive terms is

[tex]R_n = T_{n+1}/T_n = (-1)^{n+1} (3n+3)(n+1) / (-1)^n (3n)(n!) \\= (-1)^{n+1} * 3 * (n+1) / (n!)[/tex]

Taking the limit as n approaches infinity:

[tex]L = lim_{n - > \infty} \ R_n = lim_{n - > \infty} (-1)^{n+1} * 3 * (n+1) / (n!)[/tex]

Since [tex](-1)^{n+1}[/tex] alternates between -1 and 1, the limit approaches 0 and |L| < 1, which means the series converges.

To approximate the sum of the series, we can use a numerical method such as the Euler-Maclaurin formula. The formula approximates the sum of an infinite series by the sum of its first few terms and the remainder term:

[tex]\Sigma_n^\infty=1T_n \approx \Sigma_{i=1}^m T_i + R_m[/tex]

where [tex]R_m[/tex] is the remainder term that decreases as m increases

For example, let's choose m = 5:

[tex]\Sigma_{i=1}^5 T_i = T_1 + T_2 + T_3 + T_4 + T_5[/tex]

= -3! + (-1) * 3 * 2! + (-1) * 2 * 3 * 1! + (-1) * 3 * 4! + (-1) * 4 * 3 * 2! = -6 + 6 - 2 + 24 - 24 = -2

The remainder term [tex]R_m[/tex] can be estimated using the Euler-Maclaurin formula:

[tex]R_m = -B_{2m} / (2m)! * T_{m+1}[/tex]

where B_k are the Bernoulli numbers.

For [tex]m = 5, B_2m = B_{10} = -1/252[/tex], so

[tex]R_m = -B_{10} / (10)! * T_{m+1} = -1/252 * (-1)^6 * 3 * 6! = 1/252 * 3 * 720 = 9[/tex]

Therefore, the sum of the series is approximately

[tex]\Sigma_{i=1}^\Infty T_i \approx \Sigma_{i=1}^5 \ T_i + R_m \\= -2 + 9 = 7[/tex]

When finding an antiderivative using the method of guess and check, it is important to use a guess that is based on the original function and the rules of differentiation.

One approach to finding an antiderivative of a function is the method of guess and check. This involves making an educated guess for the antiderivative and then verifying it by taking the derivative of the guess and comparing it to the original function.

To find the antiderivative of f(x) = sin(x)cos(x), we can start with a guess based on the product rule for differentiation: d/dx (uv) = u * dv/dx + v * du/dx

Since f(x) = sin(x)cos(x), we can write: d/dx (sin(x)cos(x)) = cos^2(x) + sin^2(x) = 1

This suggests that the antiderivative of f(x) = sin(x)cos(x) might be: F(x) = sin(x)sin(x) + C, where C is an arbitrary constant of integration.

To check our guess, we need to take the derivative of F(x) and compare it to the original function f(x): d/dx (sin(x)sin(x) + C) = cos(x)sin(x)

If our guess is correct, the derivative of F(x) should equal f(x). However, in this case, our guess does not match the original function f(x), so we need to make another guess. A second guess could be:

F(x) = -cos(x)cos(x) + C

Taking the derivative: d/dx (-cos(x)cos(x) + C) = -sin(x)cos(x)

This time, the derivative of F(x) does match the original function f(x), so our guess is correct and the antiderivative of f(x) = sin(x)cos(x) is:

F(x) = -cos(x)cos(x) + C.

Thus, In conclusion, when finding an antiderivative using the method of guess and check, it is important to use a guess that is based on the original function and the rules of differentiation. By checking the derivative of the guess and comparing it to the original function, we can determine whether or not our guess is correct.
