Answer:

90-degree angle  

as you can see, there is clearly a 90 degree right next to it, but that doesn't tell us anything, because it has symmetry with the 3 right next to it, all that is different is that it has a longer x-axis, which will not affect our answer.

The equation states that the sum of these temperature values, multiplied by -47 Tm.n divided by (4.35 * k), should equal zero. This equation likely arises from a discretization scheme for solving a heat transfer or diffusion problem numerically, where the temperature at each grid point is approximated based on neighboring points.

The equation you provided is:

Tm,n+1 + Tm,n-1 + Tm+1,1 + Tm-in = -47 Tm.n / (4.35 * k)

This equation appears to represent a numerical scheme or a finite difference approximation for solving a partial differential equation. The equation relates the temperature values at different grid points in a two-dimensional domain. Here's a breakdown of the terms in the equation:

• Tm,n+1 represents the temperature at the (m, n+1) grid point.

• Tm,n-1 represents the temperature at the (m, n-1) grid point.

• Tm+1,1 represents the temperature at the (m+1, 1) grid point.

• Tm-in represents the temperature at the (m, n) grid point.

• k is a constant related to the thermal conductivity of the material.

• 4.35 is a scaling factor.

The standard deviation of the concentration of the unknown sample can be calculated using the formula: Standard deviation of concentration = (Standard deviation of absorbance) / (Average absorbance)

In this case, the standard deviation of the absorbance is given as 0.11 units and the average absorbance is given as 1.23 units.
Using the formula, we can calculate the standard deviation of the concentration:
Standard deviation of concentration = 0.11 / 1.23

= 0.0894
So, the standard deviation of the concentration of the unknown sample is approximately 0.0894.
The standard deviation of the concentration of the unknown sample is 0.0894.
The standard deviation of the concentration of the unknown sample measures how spread out the concentrations are from the average concentration.

It is an important statistical measure that helps in assessing the reliability and precision of the measurements.

In this case, we are given the average absorbance of the unknown sample as 1.23 units and the standard deviation of the absorbance as 0.11 units.

To find the standard deviation of the concentration, we use the formula:

Standard deviation of concentration = (Standard deviation of absorbance) / (Average absorbance).

Plugging in the values, we get:

Standard deviation of concentration = 0.11 / 1.23

= 0.0894.

Therefore, the standard deviation of the concentration of the unknown sample is approximately 0.0894.

This means that the concentrations of the unknown sample measured three times may vary by around 0.0894 units from the average concentration.

It is important to consider this variability when interpreting the results and making conclusions based on the measurements.

To find ln(x³y) in terms of u and v, we can use the properties of logarithms. ln(x³y) can be rewritten as ln(x³) + ln(y), and using the property ln(a^b) = bˣ ln(a), we have 3ln(x) + ln(y) = 3u + v.

To find ln(x³y) in terms of u and v, we can use the properties of logarithms. ln(x³y) can be rewritten as ln(x³) + ln(y), and using the property ln(a^b) = bˣ ln(a), we have 3ln(x) + ln(y) = 3u + v.

The domain of the function f(x) = ln(x-3) is x > 3, since the natural logarithm is undefined for non-positive values. The x-intercept occurs when f(x) = 0, so ln(x-3) = 0, which implies x - 3 = 1. Solving for x gives x = 4 as the x-intercept.

There are no vertical asymptotes for the function f(x) = ln(x-3) since the natural logarithm is defined for all positive values. However, the graph approaches negative infinity as x approaches 3 from the right, indicating a vertical asymptote at x = 3.

To sketch the graph of f(x) = ln(x-3), we start with the x-intercept at (4, 0). We can plot a few more points by choosing values of x greater than 4 and evaluating f(x) using a calculator.

As x approaches 3 from the right, the graph approaches the vertical asymptote at x = 3. The graph will have a horizontal shape, increasing slowly as x increases. Remember to label the axes and indicate the asymptote on the graph.

Pascal's triangle can be used to expand the binomial (d-3)^6. The expansion involves applying the binomial theorem and using the coefficients from the corresponding row of Pascal's triangle.

In this case, the sixth row of Pascal's triangle is 1 6 15 20 15 6 1, which represents the coefficients for each term in the expansion of (d-3)^6.

The binomial theorem states that for any binomial expression (a+b)^n, the expansion can be represented as the sum of terms of form C(n, k) * a^(n-k) * b^k, where C(n, k) is the binomial coefficient obtained from Pascal's triangle.

In this case, we have (d-3)^6, so the expansion will have seven terms corresponding to the powers of d from 6 to 0. Using the coefficients from the sixth row of Pascal's triangle, we can write the expanded form as:

(d-3)^6 = 1d^6 + 6d^5*(-3) + 15d^4(-3)^2 + 20d^3(-3)^3 + 15d^2(-3)^4 + 6d(-3)^5 + 1*(-3)^6.

Simplifying the terms and raising -3 to different powers, we can obtain the expanded form of (d-3)^6.

Step-by-step explanation:

The number of adult tickets that were sold would be = 435 tickets.

A ticket is an official document that gives an individual access to an event.

The cost of adult tickets = $8

The cost for student tickets = $4

The number of students tickets sold = X

The number of adults tickets sold = X +30

The told number of tickets sold = 840

To find X;

X + X + 30 = 840

2x + 30 = 840

2x = 840-30

2x = 810

X = 810/2

X = 405

Therefore, the number of tickets sold for adults = 405 +30 = 435 tickets.

Answer: Solution = (- 3, 2)

Explanation:

The system of equations is

6x + 8y = -2

-5x - 7y = 1

We would eliminate x. The first step is to multiply equation 1 by 5 and equation 2 by 6. We have

30x + 40y = - 10

- 30x - 42y = 6

By adding both equations, we have

30x + - 30x + 40y + - 42y = - 10 + 6

30x - 30x + 40y - 42y = - 4

- 2y = - 4

Dividing both sides by - 2,

- 2y/- 2 = - 4/- 2

y = 2

Substitu4ing y = 2 into equation 1, we hav

6x + 8 * 2 = -2

6x + 16 = - 2

Subtracting 16 from bth sides,

6x + 16 - 16 = - 2 - 16

6x = - 18

Dividing both sides by 6,

6x/6 = - 18/6

x = - 3

Solution = (- 3, 2)

Answer:

It looks like you are trying to find the retail price for a given quantity of pairs. To write an equation that could be used to find the retail price for each range of quantities, you will need to know the following information:

The retail price for the first range (0-20 pairs)

The retail price for the second range (21-40 pairs)

The retail price for the third range (41-60 pairs)

The retail price for the fourth range (61-80 pairs)

The retail price for the fifth range (81 or more pairs)

Once you have this information, you can use an if-then statement to create an equation that will work consistently for each range. The equation might look something like this:

if (quantity >= 0 and quantity <= 20):

retail_price = price for 0-20 pairs

elif (quantity >= 21 and quantity <= 40):

retail_price = price for 21-40 pairs

elif (quantity >= 41 and quantity <= 60):

retail_price = price for 41-60 pairs

elif (quantity >= 61 and quantity <= 80):

retail_price = price for 61-80 pairs

else:

retail_price = price for 81 or more pairs

This equation will work consistently for each range because it uses a series of conditions to determine which retail price to use based on the quantity of pairs.

EDIT:

To find the retail price for a given quantity of pairs based on the wholesale prices you provided, you can use the following equation:

if (quantity >= 0 and quantity <= 20):

retail_price = 25.00

elif (quantity >= 21 and quantity <= 40):

retail_price = 23.00

elif (quantity >= 41 and quantity <= 60):

retail_price = 21.00

elif (quantity >= 61 and quantity <= 80):

retail_price = 19.00

else:

retail_price = 17.00

This equation will work consistently for each range because it uses a series of conditions to determine the retail price based on the quantity of pairs. The retail price will be 25.00 for quantities in the first range (0-20 pairs), 23.00 for quantities in the second range (21-40 pairs), 21.00 for quantities in the third range (41-60 pairs), 19.00 for quantities in the fourth range (61-80 pairs), and 17.00 for quantities in the fifth range (81 or more pairs).

Approximately 34% of American adults have a mobile phone but not a landline, based on the given proportions from the study conducted by the Centers for Disease Control.

The proportion of American adults who have a mobile phone but not a landline, we need to subtract the proportion of those who have both a mobile phone and a landline from the proportion of those who have a mobile phone.

Let's denote the proportion of American adults who have a mobile phone as P(M), the proportion who have a landline as P(L), and the proportion who have neither as P(N).

Given information:

P(M) = 89% (proportion with a mobile phone)

P(L) = 57% (proportion with a landline)

P(N) = 2% (proportion with neither)

We can now calculate the proportion of adults who have a mobile phone but not a landline using the following equation:

P(M and not L) = P(M) - P(M and L)

To find P(M and L), we can subtract P(N) from P(L) since those who have neither are not included in the group with a landline:

P(M and L) = P(L) - P(N)

P(M and L) = 57% - 2%

P(M and L) = 55%

Now we can substitute the values back into the equation to find P(M and not L):

P(M and not L) = P(M) - P(M and L)

P(M and not L) = 89% - 55%

P(M and not L) = 34%
