If she wants to put a fence around the perimeter of her patio and each piece of fencing is feet long, how many 5 2pieces of fencing will she need to completely enclose her patio

Answer:

62.5 J

Step-by-step explanation:

Formula

Given :

Solving

The work done with the given force and distance is 62.5 Newton meter.

The basic concept of Time and Work is similar to that across all Arithmetic topics, i.e. the concept of Proportionality. Efficiency is inversely proportional to the Time taken when the amount of work done is constant.

Given that, force = 25 N weight and distance = 2.5 meters

We know that, work = Force×Distance

Here, work = 25×2.5

= 62.5 Newton meter

Therefore, the work done is 62.5 Newton meter.

Answer: Answer:the person entering the room is 10 years oldStep-by-step explanation:x / 5 = 40x = 40 * 5x = 200so the total of all the ages of 5 people

Step-by-step explanation:

The speed of the car on a paved road if it took 10 hours to cover the entire road​is 36.5 km/h.

Average speed is the total distance traveled divided by the total time taken to travel that distance.

The speed of the car on a paved road can be calculated by using the following formula:

Total Distance / Total Time = Average Speed

Total Distance = 67.5% of 540 km

= 365 km

Total Time = 10 hours

Average Speed = 365 km ÷ 10 hours

= 36.5 km/h

Therefore, the speed of the car on a paved road is 36.5 km/h.

This is because, since 67.5% of the total 540 km road is paved, the car would be travelling faster on the paved roads than on the unpaved roads, hence resulting in an average speed of 36.5 km/h on the paved roads.

Since the unpaved roads have a lower speed, the total time taken to cover the entire road would be more than 10 hours if the car was travelling only on the unpaved roads.

Hello. :)

So, in order to order numbers, you need to have them all in the same format. For example, in your case, half are fractions and half are decimals. If you want to order them, they all need to be either fractions or decimals.

Let's just convert them to decimals.

In order to do that, all you have to do is divide the numerator by the denominator. Do this to all of the fractions.

-3/10 = -0.3

1/2 = 0.5

Okay, so now all of our terms are in decimal form:

-0.3, 0.5, 0.3, -0.8

So let's start the Ordering process.

Begin with the negative numbers, since they are going to be the smallest.

We have -0.3 and -0.8. If they were positive, 0.8 would be larger. But, in terms of negatives, -0.8 is less than -0.3

So, we have -0.8, -0.3.

Now the positives:

0.5 and 0.3. Just looking at the decimals, you can see that 0.5 is greater than 0.3

So, from least to greatest your answer is:

-0.8, -3/10, 0.3, and 1/2

First, we need to determine how many pounds of food the ocicat eats in a week. There are 7 days in a week, so the ocicat eats $\frac 35$ pounds/day * 7 days/week = $\frac{7}{5}$ pounds/week.

Next, we need to divide the total amount of food in the bag by the amount of food that the ocicat eats in a week to determine how many weeks the bag of food will last. The bag of food weighs 19 1/2 pounds, so it will last for a total of 19 $1/2 pounds / $7/5 pounds/week = $33/7 weeks.

Finally, we need to divide the total number of weeks that the bag of food will last by the number of ocicats that the food will feed to determine how many ocicats the bag of food will feed for one week. The bag of food will feed $33/7 weeks / 1 week/ocicat = $33/7 ocicats.

Therefore, the 19 $1/2-pound bag of food will feed $33/7 ocicats for one week.

Gaussian elimination with partial pivoting can fail due to rounding errors or when a pivot element is very close to zero.

Without knowing the specific system of equations, it is not possible to determine at what point the Gaussian elimination process with partial pivoting would fail using exact arithmetic.

In the latter case, the algorithm can fail to find a suitable pivot and the elimination process can become unstable. This is known as a singularity or numerical instability.

To prevent this, in practice, pivoting strategies are used to avoid dividing by small or zero pivot elements. Additionally, high-precision arithmetic can be used to reduce the impact of rounding errors.

According to the law of sines, the ratio of a side length to the sine of its opposite angle is constant for all sides of a triangle. In this case, we have BC/sin(B) = AB/sin(C). We have 646/sin(111.0°) = AB/sin(18.6°). Solving this equation, we find that AB is 1907.7 m when rounded to the nearest meter.

To explain further, the law of sines relates the ratios of the lengths of the sides of a triangle to the sines of their opposite angles. In our case, BC is the side opposite angle B, and AB is the side opposite angle C. By rearranging the formula BC/sin(B) = AB/sin(C), we can solve for AB. We substitute the given values and use a calculator to find the approximate value of AB. Rounding to the nearest meter gives us the final answer of 1907.7 m.

Answer: 2n - 64

Step-by-step explanation:

If the vairiable n describes the unknown number, and there is twice the number, then we can use the term 2n.

We also have 64 less then that number, and less means to subtract. Therefore, the equation is 2n - 64.

Answer:

2n-64

Step-by-step explanation:

I believe this is the correct answer (Not exactly sure to be honest)

Twice a number means to multiply by 2, so you use the variable (n) and multiply it by 2. For subtracting 64, I believe you usually put it after the (2n) portion of the equation.

The values of y when x is 3, 4, and 5 are 21, 25, and 29, respectively.

To find the values of y when x is 3, 4, and 5 using the equation y = 4x + 9, we substitute the respective values of x into the equation and solve for y.

For x = 3:

y = 4(3) + 9

y = 12 + 9

y = 21

For x = 4:

y = 4(4) + 9

y = 16 + 9

y = 25

For x = 5:

y = 4(5) + 9

y = 20 + 9

y = 29

So, the values of y when x is 3, 4, and 5 are 21, 25, and 29, respectively.

The Steepest descent method is an optimization method that makes use of the gradient vector to determine the direction of the steepest descent for an unconstrained function.

The steps for applying the method to an exact line search are explained below:

Step 1: InitializationSelect an initial point x0 and set the iteration counter k=0.

Step 2: Compute the search directionThe search direction at the k-th iteration can be calculated as the negative of the gradient vector at xk.

Step 3: Find the step sizeThe step size in the direction of the search direction can be found by minimizing the function along the search direction.

In other words, the step size is given byαk=argmin α≥0 f(xk+αpk)This can be done by setting the derivative of the function f(xk+αpk) with respect to α to zero, and solving for α. The resulting value of α is the optimal step size.

Step 4: Update the iteration counterSet k=k+1.

Step 5: Update the current pointUpdate the current point as xk+1=xk+αkpk.

Step 6: Check for convergenceIf the convergence criterion is not satisfied, go to step 2. Otherwise, stop.The convergence criterion can be a specific value of the gradient norm, or a maximum number of iterations can be set as the stopping criterion. In this case, the function f(x) is given as:f(x1,x2)=x12+2x22+4x1+4x2

Therefore, we need to find the minimum value of f(x) by applying the steepest descent method by exact line search. The search direction can be calculated as follows:∇f(xk)= [2x1+4, 4x2+4]pk=−∇f(xk)=[−2x1−4,−4x2−4]

The step size can be obtained by solving the following equation:αk=argmin α≥0 f(xk+αpk)=argmin α≥0 (x1+αpk1)2+2(x2+αpk2)2+4(x1+αpk1)+4(x2+αpk2)

Expanding the equation and simplifying, we get:αk=4/(2(pk12+2pk22+4pk1+4pk2))=2/(pk12+2pk22+4pk1+4pk2)

The current point can be updated as:xk+1=xk+αkpk=(x1+2x1+4/(2(pk12+2pk22+4pk1+4pk2)), x2+2x2+4/(2(pk12+2pk22+4pk1+4pk2)))

Therefore, the steepest descent method by exact line search can be applied iteratively until the convergence criterion is met, or until a maximum number of iterations is reached. Each iteration requires the computation of the search direction, the step size, and the current point.

The given task is to sort a list of 3-D points based on a given sorting order string using Python's lambda function and sorted function. The sorting order is specified as a string of any combination of 'x', 'y', and 'z', where 'x' represents the primary sorting key, 'y' represents the secondary sorting key, and 'z' represents the last priority.

In Python, we can use a lambda function to define a custom key for sorting using the `sorted()` function. We can create a tuple of the `x`, `y`, and `z` coordinates of each point and pass it as the key to the `sorted()` function. We can use the `index()` method to get the index of the corresponding letter in the sorting order string.Here's an example of the two-line solution to sort the given list of points based on the sorting order string:

```python

sorted_points = sorted(points, key=lambda p: (p[order.index('x')], p[order.index('y')], p[order.index('z')]))

print(sorted_points)

```This will print the sorted list of 3-D points based on the given sorting order string.

In summary, we can use Python's lambda function and sorted function to sort a list of 3-D points based on a given sorting order string. The lambda function creates a tuple of the `x`, `y`, and `z` coordinates for each point based on the sorting order string, and the sorted function sorts the list based on this tuple.
