The square of the distance between two points is the sum of the squares of the difference between two coordinates. The value of n can be -13 or 3.

The distance between two points is given by the formula,

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

As it is given that the distance between points R and S is half the distance between points S and T.

\(2(RS) = ST\)

Now, the distance between RS can be written as,

\(RS=\sqrt{[-6-(-2)]^2+[-5-(-5)]^2}\\RS = \sqrt{(-6+2)^2+(0)^2}\\RS = \sqrt{16}\\RS = \pm 4\)

Further, we can write,

\(2(RS) = ST\\\\2(\pm 4) = \sqrt{[-2-(-2)]^2+[-5-n]^2}\\\\\pm 8 = \sqrt{(0)^2+(-5-n)^2}\\\\\pm 8^2=(-5-n)^2\\\\\pm8=(-5-n)\\\\\)

When the value of 8 is positive,

\(+8+5=-n\\\\13=-n\\\\n=-13\)

When the value of 8 is negative,

\(-8+5=-n\\\\-3=-n\\\\n=3\)

Hence, the value of n can be -13 or 3.

Answer:

Both pass there all higher the 50%

Absolute maximum value: 19/8
Absolute minimum value: -1/4

A more detailed explanation of the answer.

To find the absolute and local maximum and minimum values of f, we'll first sketch the graph of the function f(x) and then analyze the graph.

f(x) = 1/8(7x - 2), x ≤ 3

Step 1: Sketch the graph.
Since the function is linear, we only need two points to sketch the graph. Let's choose x = 0 and x = 3.

For x = 0:
f(0) = 1/8(7(0) - 2) = -1/4

For x = 3:
f(3) = 1/8(7(3) - 2) = 1/8(19) = 19/8

Now, we have two points (0, -1/4) and (3, 19/8). Draw a line connecting these two points. The graph is a straight line with a slope greater than 0, meaning the function is increasing as x increases.

Step 2: Analyze the graph to find the maximum and minimum values.
Since the function is increasing as x increases, the local minimum value occurs at x = 0 and is equal to -1/4. As x approaches the limit of the domain, x = 3, the function reaches its local maximum value of 19/8.

Since the domain is restricted to x ≤ 3, there are no other possible local or absolute maximum and minimum values.

So, the absolute maximum value is 19/8 and the absolute minimum value is -1/4.

The width of the new rectangular field would be 0 meters, which means it would essentially be a line segment.

To find the length and width of another rectangular field that has the same perimeter but a larger area, we can use the following steps:

1. Calculate the perimeter of the given rectangular field:

  Perimeter = 2 * (Length + Width)

            = 2 * (120 meters + 80 meters)

            = 2 * 200 meters

            = 400 meters

2. Divide the perimeter by 2 to find the equal sides of the new rectangular field. Since the perimeter is divided equally into two sides, each side would be half of the perimeter length:

  Side length = Perimeter / 2

             = 400 meters / 2

             = 200 meters

3. Now, we have the side length of the new rectangular field. However, we need to determine the length and width that would yield a larger area. One way to achieve this is to make one side longer and the other side shorter.

4. Let's assume the length of the new rectangular field is 200 meters. Since both sides have the same length, the width can be calculated using the formula for the perimeter:

  Width = Perimeter / 2 - Length

        = 400 meters / 2 - 200 meters

        = 200 meters - 200 meters

        = 0 meters

5. Therefore, the width of the new rectangular field would be 0 meters, which means it would essentially be a line segment. However, note that the question asks for a rectangular field with a larger area. Since the width cannot be zero, we can conclude that it is not possible to have a rectangular field with the same perimeter but a larger area than the given field.

In summary, it is not possible to find another rectangular field with the same perimeter but a larger area than the rectangular field with dimensions 80 meters wide and 120 meters long.

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

When two variables vary along with each other but the data points are loosely scattered around the line of best fit, the correlation is weak correlation.

We need to find the type of correlation when two variables vary along with each other but the data points are loosely scattered around the line of best fit.

A scatter plot helps find the relationship between two variables. This relationship is referred to as a correlation. Based on the correlation, scatter plots can be classified as follows.

A weak positive correlation indicates that, although both variables tend to go up in response to one another, the relationship is not very strong. A strong negative correlation, on the other hand, indicates a strong connection between the two variables, but that one goes up whenever the other one goes down.

Therefore, when two variables vary along with each other but the data points are loosely scattered around the line of best fit, the correlation is weak correlation.

The nearest whole number after rounding is, 14

Rounding a number to the nearest tenth means finding the nearest multiple of 0.1.

To do this, you need to look at the digit in the hundredths place (the second digit after the decimal point) of the number you want to round.

If that digit is 5 or greater, you round the number up by adding 0.1 to the nearest whole number.

If that digit is 4 or less, you round the number down by leaving the nearest whole number unchanged.

For example, rounding 3.456 to the nearest tenth gives 3.5, while rounding 3.444 to the nearest tenth gives 3.4.

Given that,

The decimal number  13.5,

The rectangular stainless steel tank should have outer dimensions of approximately 4.87 feet in length, 2.87 feet in width, and 12.87 feet in height to meet the given constraints.

To determine the outer dimensions of the tank, we'll need to find the length, width, and height of the tank based on the given constraints.

Let's assume:

Length of the tank = L (in feet)

Width of the tank = L - 2 (as the width should be 2 feet less than the length)

Height of the tank = L + 8 (as the height should be 8 feet more than the length)

The volume of the tank can be calculated as follows:

Volume = Length * Width * Height

Given that the volume should be 89.58 cubic feet, we have the equation:

89.58 = L * (L - 2) * (L + 8)

Simplifying the equation:

89.58 = L * (L^2 + 6L - 16)

Expanding the equation:

89.58 = L^3 + 6L^2 - 16L

Now, let's solve this equation to find the value of L (length).

Since this is a cubic equation, we'll need to use numerical methods or a calculator to find the value of L. Using a numerical solver, the value of L is approximately 4.87 feet.

Now that we have the length, we can calculate the width and height:

Width = L - 2 ≈ 4.87 - 2 ≈ 2.87 feet

Height = L + 8 ≈ 4.87 + 8 ≈ 12.87 feet

Therefore, the outer dimensions of the tank should be approximately:

Length: 4.87 feet

Width: 2.87 feet

Height: 12.87 feet

Answer:its correct

Step-by-step explanation:

False. The derivative of the function f(x) = 5sin(x) + cos(x) is not equal to -5cos(x) - sin(x). The correct derivative of f(x) can be obtained by applying the rules of differentiation.

To find the derivative, we differentiate each term separately. The derivative of 5sin(x) is obtained using the chain rule, which states that the derivative of sin(u) is cos(u) multiplied by the derivative of u. In this case, u = x, so the derivative of 5sin(x) is 5cos(x).

Similarly, the derivative of cos(x) is obtained as -sin(x) using the chain rule.

Therefore, the derivative of f(x) = 5sin(x) + cos(x) is:

f'(x) = 5cos(x) - sin(x).

This result shows that the derivative of f(x) is not equal to -5cos(x) - sin(x).

In summary, the statement that f'(x) = -5cos(x) - sin(x) is false. The correct derivative of f(x) = 5sin(x) + cos(x) is f'(x) = 5cos(x) - sin(x).

This is the exact answer in symbolic notation and fractions .The integral of (6/((11+t^2)(1+t^2))) dt is a bit complicated and requires partial fraction decomposition.

We can factor the denominator:
11 + t^2 = (11 - i^2)(1 + t^2/(11-i^2)) = 10(1 + t^2/10) + i^2(1 - t^2/11)
1 + t^2 = (1 + i^2)(1 + t^2/(1+i^2))
So we have:
6/((11+t^2)(1+t^2)) = A/(10(1 + t^2/10) + i^2(1 - t^2/11)) + B/(1 + i^2)(1 + t^2/(1+i^2))
6 = A(1 + i^2)(11)(1) + B(10)(11)(1)

The first integral can be evaluated using the substitution u = (10/11)t and then the identity 1 + tan^2(x) = sec^2(x) for the denominator. We get:
-3/(11+10i) * arctan(t/√(110)) + 3/(110 + 11i) * arctan(t/√2)
Evaluating from 0 to 15, we get:
-3/(11+10i) * arctan(15/√(110)) + 3/(110 + 11i) * arctan(15/√2)
