The main answer is that without specific values or elements for sets A and B, we cannot determine the result of A - B and B - A.

To find A - B, we need to subtract the elements in set B from set A. Similarly, to find B - A, we need to subtract the elements in set A from set B.

However, I need the specific values or elements of sets A and B to perform the calculations. Could you please provide the values or elements of the sets?In order to perform set subtraction, we need the specific elements or values of sets A and B. Set subtraction involves removing the common elements between the sets.

Let's say set A is {1, 2, 3} and set B is {2, 3, 4}. To find A - B, we remove the elements in set B from set A. Thus, A - B would be {1}.

To find B - A, we remove the elements in set A from set B. Therefore, B - A would be {4}.

Please provide the values or elements of sets A and B, and I will be able to calculate A - B and B - A accordingly.

Answer:

Le temps écoulé entre 20h00 et 6h30 est 10h30
Mais celui entre 06h30 et 20h00 est 14h30

Step-by-step explanation:

Tout dépend du temps de départ

well, if the water is coming out at 0.44 ft³ per minute, and you take a shower for 8 mins, that simply means  you used 8*0.44 ft³, or namely 3.52 ft³.

what if you instead fill the bathtub with 0.45 yd³?  is that more or less than 3.52ft³?

\(\begin{array}{ccll} yard&(yard)^2&(yard)^3\\ \cline{1-3} (3~ft)&(3~ft)^2&(3~ft)^3\\ 3~ft&3^2~ft^2&3^3~ft^3\\ &9~ft^2&27~ft^3 \end{array}\)

so then, there are that many ft³ in a yd³, so how many will there be in 0.45yd³ anyway?

\(\begin{array}{ccll} yd^3&ft^3\\ \cline{1-2} 1&27\\ 0.45&x \end{array}\implies \cfrac{1}{0.45}=\cfrac{27}{x}\implies x=27(0.45)\implies x=12.15~ft^3\)

well, then you'd use more water with the  0.45yd³ and some soap btw, by how much more?  12.15 - 3.52 = 8.63 ft³.

Taking an 8-minute shower uses less water than filling a bathtub with 0.45 cubic yards of water.

Given that;

Suppose water flows from a shower at a rate of 0.44 cubic feet per minute.

For the shower, the flow rate is 0.44 cubic feet per minute, and you take an 8-minute shower.

So, the total amount of water used in the shower is:

0.44 cubic feet/minute × 8 minutes

= 3.52 cubic feet

Now let's convert cubic feet to cubic yards since the bathtub is measured in cubic yards.

There are 27 cubic feet in 1 cubic yard, so:

3.52 cubic feet × (1 cubic yard / 27 cubic feet)

= 0.1304 cubic yards

Therefore, the water usage for an 8-minute shower is 0.1304 cubic yards.

On the other hand, when filling a bathtub with 0.45 cubic yards of water, that is the exact amount of water used.

Comparing the two scenarios, we can see that taking an 8-minute shower uses less water than filling a bathtub with 0.45 cubic yards of water.

Based on the net present value profile, Project H has a higher NPV than Project E.

To compare the net present value (NPV) of Project E and Project H, we need to calculate the present value of cash flows for each project and determine which one has a higher NPV. The cash flow patterns for the two projects are as follows:

Project E:

Initial investment: -$100,000

Cash flows for Year 1: $40,000

Cash flows for Year 2: $50,000

Cash flows for Year 3: $60,000

Project H:

Initial investment: -$120,000

Cash flows for Year 1: $60,000

Cash flows for Year 2: $50,000

Cash flows for Year 3: $40,000

To calculate the present value of cash flows, we need to discount them using an appropriate discount rate. The discount rate represents the required rate of return or the cost of capital for the company. Let's assume a discount rate of 10%.

Using the formula method, we can calculate the present value (PV) of each cash flow and sum them up to obtain the NPV for each project:

For Project E:

PV = $40,000/(1 + 0.10)^1 + $50,000/(1 + 0.10)^2 + $60,000/(1 + 0.10)^3

PV = $36,363.64 + $41,322.31 + $45,454.55

PV = $123,140.50

For Project H:

PV = $60,000/(1 + 0.10)^1 + $50,000/(1 + 0.10)^2 + $40,000/(1 + 0.10)^3

PV = $54,545.45 + $41,322.31 + $30,251.14

PV = $126,118.90

Using the financial calculator method, we can input the cash flows and the discount rate to calculate the NPV directly. By entering the cash flows for each project and the discount rate of 10%, we find that the NPV for Project E is approximately $123,140.50 and the NPV for Project H is approximately $126,118.90.

Triangle ABC and ADE are similar triangles

Similar triangles have the same corresponding angle measures and proportional side lengths.

In mathematical terms, if y and z are the lengths of the two shorter sides (also known as the legs) of a right triangle, and x is the length of the hypotenuse, the Pythagorean theorem can be expressed as:

x² = y² + z²

In the questions given, the only one we can use Pythagorean theorem to solve is the one with ladder since it's forms a right-angle triangle.

To calculate the length of the ladder, we can write the formula as;

And no withdrawals are made from the account.

Now, we need to determine the amount of 8% interest on the $5000,

\(=\frac{5000}{100}*8\\ =400\)

Then, the amount in the account at the end of 1 year =$5000+$400

"Distance traveled is a function of time." In the context of motion or travel, the distance traveled is often dependent on the amount of time that has passed.

Distance is a fundamental concept in physics and mathematics that measures the extent or length between two points.

It represents the amount of ground covered or space traveled. When we say that distance is a function of various factors, it means that different variables or parameters can influence the distance traveled.

In the context of motion or travel, the distance traveled is often dependent on the amount of time that has passed.

The sentence "Distance traveled is a function of time" expresses this relationship, indicating that the distance traveled can be determined or calculated based on the value of time.

Thus, it implies that as time changes, the corresponding distance traveled also changes, establishing a functional relationship between the two variables.
