Answer:1/6

Step-by-step explanation:

The company can maximize its revenue by charging the price of $73 per phone.

Changing the price and monitoring how many phones are sold in reaction to the price change allows for trial-and-error in determining accuracy.

With 520 phones sold each week at $73, the corporation will make a total of $38,160 in revenue. There are 20 more phones than when it was charging $75, thus the business will make an additional $1,500 every week.

Due to the increased number of phones sold, the corporation may increase revenue by merely $2 by lowering the price, leading to an increase in both total revenue and profit.

Step-by-step explanation:

you have to simplify it

1. Objective Function and Constraints:

Maximize 2x1 + 3x2 + 5x3 subject to x1 + x2 + x3 ≤ 1500, x1 + x2 ≤ 1100, x2 ≤ 800, x3 ≤ 400.

2. Using Excel Solver, find the optimal allocation of funds.

3. The maximum value of the objective function is reported by Excel Solver.

We have,

Objective Function and Constraints:

Let:

x1 = amount spent on food

x2 = amount spent on shelter

x3 = amount spent on entertainment

Objective Function:

Maximize: 2x1 + 3x2 + 5x3 (since each dollar spent on food has a satisfaction value of 2, each dollar spent on shelter has a satisfaction value of 3, and each dollar spent on entertainment has a satisfaction value of 5)

Constraints:

Subject to:

x1 + x2 + x3 ≤ $1,500 (maximum disposable income)

x1 + x2 ≤ $1,100 (amount spent on food and shelter combined must not exceed $1,100)

x2 ≤ $800 (amount spent on shelter alone must not exceed $800)

x3 ≤ $400 (entertainment cannot exceed $400)

Using Excel Solver:

In Excel, set up a spreadsheet with the following columns:

Column A: Variable names (x1, x2, x3)

Column B: Objective function coefficients (2, 3, 5)

Column C: Constraints coefficients (1, 1, 1) for the first constraint (maximum disposable income)

Column D: Constraints coefficients (1, 1, 0) for the second constraint (amount spent on food and shelter combined)

Column E: Constraints coefficients (0, 1, 0) for the third constraint (amount spent on shelter alone)

Column F: Constraints coefficients (0, 0, 1) for the fourth constraint (entertainment limit)

Column G: Right-hand side values ($1,500, $1,100, $800, $400)

Apply the Excel Solver tool with the objective function and constraints to find the optimal allocation of funds.

Once the Excel Solver completes, it will report the maximum value of the objective function, which represents the optimal satisfaction value achieved within the given budget constraints.

Thus,

Objective Function and Constraints: Maximize 2x1 + 3x2 + 5x3 subject to x1 + x2 + x3 ≤ 1500, x1 + x2 ≤ 1100, x2 ≤ 800, x3 ≤ 400.

Apologies for the previous confusion. Let's reconsider the problem to find the correct parameterization.

a. Inside the cylinder x^2 + y^2:

To find a parametrization of the portion of the plane x + y + z = 3 that is inside the cylinder x^2 + y^2, we can use cylindrical coordinates.

In cylindrical coordinates, we have:

x = ρ*cos(θ)

y = ρ*sin(θ)

z = 3 - ρ*cos(θ) - ρ*sin(θ)

Using the equation of the plane x + y + z = 3, we can substitute these expressions to obtain:

ρ*cos(θ) + ρ*sin(θ) + (3 - ρ*cos(θ) - ρ*sin(θ)) = 3

Simplifying, we find:

ρ*cos(θ) + ρ*sin(θ) = 3

Therefore, the correct parameterization for the portion of the plane x + y + z = 3 that is contained inside the cylinder x^2 + y^2 is:

x = ρ*cos(θ)

y = ρ*sin(θ)

z = 3 - ρ*cos(θ) - ρ*sin(θ)

b. Inside the cylinder y^2 + z = 4:

To find a parametrization of the portion of the plane x + y + z = 3 that is inside the cylinder y^2 + z = 4, we can use cylindrical coordinates.

In cylindrical coordinates, we have:

x = x (remains unchanged)

y = ρ*sin(θ)

z = 4 - ρ^2

Therefore, the correct parameterization for the portion of the plane x + y + z = 3 that is contained inside the cylinder y^2 + z = 4 is:

x = x (remains unchanged)

y = ρ*sin(θ)

z = 4 - ρ^2

Answer:

10

Step-by-step explanation:

So because AC is intersected at the middle, or the midpoint, being E, you can say that both sides of AC; AE and EC, are equal to each other. You can make 4x-3=3x-1 and combine like terms to get X on one side by itself. First, you want to subtract 3x from both sides to move the x from left side and only have it on the right. You should x-3=-1. Then, you want to remove the -3 from the left side and bring it to the right to have x by itself. To cancel the -3 on the left side you have to add 3 on both sides. You should have x=2. Now that you have x, you can plug it into both AE and EC, then add them together. You should have 5 for AE and 5 for EC, and adding them up makes 10. Hope I could help :)

The given coins [1, 2, 5] and the value 11, the minimum number of coins needed is 2.

Here are the steps to find the minimum number of coins:

1. First, we create an array of size equal to the given value, initialized with a very large number. This array will store the minimum number of coins needed to make each value from 0 to the given value.

2. We set the first element of the array to 0, as it doesn't require any coins to make a value of 0.

3. Next, we iterate through all the coins available and for each coin, we iterate through all the values from the coin value to the given value.

4. For each value, we calculate the minimum number of coins needed by taking the minimum of the current minimum and the value obtained by subtracting the coin value from the current value and adding 1 to it.

5. Finally, we return the value stored in the last element of the array, which represents the minimum number of coins needed to make the given value.

Let's consider an example to better understand the process:

Given coins: [1, 2, 5]
Given value: 11

1. Initialize the array with [INF, INF, INF, INF, INF, INF, INF, INF, INF, INF, INF, INF] (INF represents infinity).

2. Set the first element of the array to 0, so it becomes [0, INF, INF, INF, INF, INF, INF, INF, INF, INF, INF, INF].

3. For the first coin (1), iterate through the array from index 1 to 11.

  - For index 1, the minimum number of coins needed is 0 + 1 = 1.
  - For index 2, the minimum number of coins needed is 0 + 1 = 1.
  - For index 3, the minimum number of coins needed is 0 + 1 = 1.
  - ...
  - For index 11, the minimum number of coins needed is 0 + 1 = 1.

  The array becomes [0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1].

4. For the second coin (2), iterate through the array from index 2 to 11.

  - For index 2, the minimum number of coins needed is 1 (minimum of 1 and 0 + 1 = 1).
  - For index 3, the minimum number of coins needed is 1 (minimum of 1 and 0 + 1 = 1).
  - For index 4, the minimum number of coins needed is 1 (minimum of 1 and 1 + 1 = 2).
  - ...
  - For index 11, the minimum number of coins needed is 1 (minimum of 1 and 1 + 1 = 2).

  The array becomes [0, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2].

5. For the third coin (5), iterate through the array from index 5 to 11.

  - For index 5, the minimum number of coins needed is 2 (minimum of 2 and 0 + 1 = 1).
  - For index 6, the minimum number of coins needed is 2 (minimum of 2 and 1 + 1 = 2).
  - ...
  - For index 11, the minimum number of coins needed is 2 (minimum of 2 and 2 + 1 = 3).

  The array becomes [0, 1, 1, 1, 2, 1, 2, 2, 2, 2, 3, 2].

Answer:

C. $571.

Step-by-step explanation:

1st you have to add up the total cost so:

213.15 + 344.21 + 76.65 = $ 634.01

next find 10% of 634.01

10% of 634.01 is 63.401

then you subtract 63.401 from 634.01 so basically you subtract the 10% discount from the total cost so:

634.01 - 63.401 = 570.609 is equal to $576.90

$576.90 is closest to $571

To solve this problem, we just need to look for the paths that match each box.

The path from start to finish box is shown by the image below.

As you can observe in the image above, the first connection is on the left of the start box because it matches the segment BD inside the box.

Then, we go to the left again because the second box contains the ray DB.

After, we go through the line BD and choose the path that matches.

We keep using the same logic until we get to the finish box.

An approximate of 4 gaps will be there in one hour that are longer than 6 seconds at the flow rate of 1800 vph.

The flow rate is given to be 1800 vph.

This means that 1800 vehicles pass through the lane every hour.

To determine the number of gaps that are longer than 6 seconds, we need to calculate the time it takes for one vehicle to pass and then subtract it from 60 minutes.

Assuming that the vehicle length is negligible, the gap between two consecutive vehicles is equal to the time taken by one vehicle to pass by completely plus the time taken by the following vehicle to reach the starting position of the preceding vehicle.

Let's say, for example, that the time it takes for one vehicle to pass is 2 seconds.

The gap between two consecutive vehicles would then be 2 + 2 = 4 seconds, meaning that there would be 60/4 = 15 gaps in one minute, or 900 gaps in one hour.  

If we assume that the time it takes for one vehicle to pass is 2 seconds, the total time taken for a vehicle to cover the distance would be 1/1800*60*60= 2 sec.

Hence, 60/2 = 30 vehicles would pass through the lane in one minute.1800 vehicles/60 minutes = 30 vehicles/min

Now, we know that the gap between two consecutive vehicles is 2 seconds, so we can calculate the number of vehicles that pass through the lane in one minute.

30 vehicles/min x 2 sec/vehicle = 60 seconds/min

We can see that there are 60 seconds in a minute.

Thus, the total time taken for a vehicle to pass is 60/1800 = 0.033 minutes.

So, the total number of gaps that are longer than 6 seconds would be:

Number of minutes in an hour = 60.

Number of vehicles that pass through the lane in an hour = 1800.

Time taken for one vehicle to pass = 0.033 minutes.

Therefore, number of gaps = 60 - (1800 x 0.033) / 6 = 4 gaps.

An approximate of 4 gaps will be there in one hour that are longer than 6 seconds.

Step-by-step explanation:

The function h(x) can be found by integrating h'(x) with respect to x. Using the given initial condition h(1) = -7, we get\(h(x) = -15/2 * (7 - x^2)^{(-2/3)} + (-7 + 15/2 * 6^{(-2/3)}).\)

To find h(x), we integrate h'(x) with respect to x. The given derivative\(h'(x) = 5x/(7-x^2)^{(5/3)\)can be simplified by factoring out x in the numerator:

\(h'(x) = 5x/(7-x^2)^{(5/3) }= 5x/((7-x)(7+x))^{(5/3)}.\)

Now, we can use the substitution u = 7 - x^2 to simplify the expression further. Taking the derivative of u with respect to x, we have du/dx = -2x, which implies dx = -du/(2x).

Substituting these values into the integral, we have:

∫h'(x) dx = ∫\(5x/((7-x)(7+x))^{(5/3)} dx\)

           = ∫\((5x/u^{(5/3)}) (-du/(2x))\)

           = ∫\((-5/u^{(5/3)})\) du.

Simplifying the expression inside the integral, we obtain:

h(x) = -5∫\(u^{(-5/3) }du\)

Integrating \(u^{(-5/3)\) with respect to u, we add 1 to the exponent and divide by the new exponent:

\(h(x) = -5 * (u^{(-5/3 + 1)}/(-5/3 + 1) + C = -5 * (u^{(-2/3)})/(2/3) + C = -15/2 * u^{(-2/3)} + C.\)

Finally, substituting back u = 7 - x^2 and applying the initial condition h(1) = -7, we can solve for the constant of integration C:

\(h(1) = -15/2 * (7 - 1^2)^{(-2/3)} + C = -7\).

Simplifying the equation and solving for C, we find:

\(-15/2 * 6^{(-2/3)} + C = -7\),

\(C = -7 + 15/2 * 6^{(-2/3)\)

Therefore, the function h(x) is given by:

\(h(x) = -15/2 * (7 - x^2)^{(-2/3)} + (-7 + 15/2 * 6^{(-2/3)}).\)

Step-by-step explanation:

The question is incomplete, as the dimension of each prism is not given.

So, I will give a general explanation.

From the question, we understand each prism.

So, to get the new volume; we simply add up the volume of each prism.

For instance (we want to make assumptions)

Rachel

\(Length = 4; Width = 3; Height = 4\)

Timothy

\(Length = 6; Width = 3; Height = 4\)

Robyn

\(Length = 4; Width = 8; Height = 3\)

So, we have:

\(Volume = Length * Width * Height\)

For each, we have:

\(Rachel =4* 3* 4 =48\)

\(Timothy= 6* 3* 4 = 72\)

\(Robyn = 4* 8* 3 = 96\)

The volume of the new

\(Volume = 48 + 72 + 96\)

\(Volume = 216\)

The dimension of new prism.

Using the assumed values, we have:

\(Length = 4; Width = 3; Height = 4\)

\(Length = 6; Width = 3; Height = 4\)

\(Length = 4; Width = 8; Height = 3\)

Now, we consider the measure of the sides

Sides with the same length will form a new side.

Side 1

\(Length =4\) --- Rachel

\(Height = 4\) ---- Timothy

\(Length = 4\) --- Robyn

The above lengths have the same measure. So, one of the sides of the new prism will assume the value of this length.

So:

\(Length = 4\) -- for the new prism

Side 2

\(Width =3\)

\(Width = 3\)

\(Height = 3\)

The above lengths have the same measure. So, one of the sides of the new prism will assume the value of this length.

So:

\(Width = 3\) -- for the new prism

Side 2

\(Height = 4\)

\(Length = 6\)

\(Width =8\)

For this, we simply add up each length.

So, we have:

\(Height = 4 + 6 + 8\)

\(Height = 18\) --- for the new prism

So, the new dimension is:

\(Length = 4\)

\(Length = 6\)

\(Height = 18\)

\(Volume = 4 * 3 * 18\)

\(Volume = 216\)
