The area of the new recreation complex is 48600 yd². The scale factor of the old community soccer field is 9, and its area is 600 yd². The new complex accommodates field hockey, football, baseball, and swimming.

To determine the new area, we need to know the following equation:

New area = (scale factor)² × old area

In this problem, we already know the old community soccer field's area, which is 600 square yards. The new outdoor recreation complex's total area, multiply the old soccer field's area by the scale factor squared:

Total area of the new recreation complex = (scale factor)² × area of the old soccer field

= (9)² × 600 yd²

= 81 × 600 yd²

= 48600 yd²

The area of the old community soccer field is 600 square yards. When an old community soccer field is enlarged by a scale factor of 9, a new outdoor recreation complex is created.

Therefore, the area of the new recreation complex is 48600 yd².

f is a gradient vector field with the potential function v(x,y,z) = -6xy. We can check that v(0,0,0) = 0, as required.

To determine the function v such that f=∇v, we need to find a scalar function whose gradient is f. We can find the potential function v by integrating the components of f.

For the x-component, we have:

∂v/∂x = -6y

Integrating with respect to x, we get:

v(x,y,z) = -6xy + g(y,z)

where g(y,z) is an arbitrary function of y and z.

For the y-component, we have:

∂v/∂y = -6x

Integrating with respect to y, we get:

v(x,y,z) = -6xy + h(x,z)

where h(x,z) is an arbitrary function of x and z.

For these two expressions for v to be consistent, we must have g(y,z) = h(x,z) = 0 (i.e., they are both constant functions). Thus, we have:

v(x,y,z) = -6xy

So, the gradient of v is:

∇v = ⟨∂v/∂x, ∂v/∂y, ∂v/∂z⟩ = ⟨-6y, -6x, 0⟩

which is the same as the given vector field f. Therefore, f is a gradient vector field with the potential function v(x,y,z) = -6xy. We can check that v(0,0,0) = 0, as required.

The minimum speed needed for a 100 g puck to make it to the top of a frictionless ramp that is 3.0 m long and inclined at 20° can be calculated using the conservation of energy principle. The potential energy gained by the puck as it reaches the top of the ramp is equal to the initial kinetic energy of the puck. Therefore, the minimum speed can be calculated by equating the potential energy gained to the initial kinetic energy. Using the formula v = √(2gh), where v is the velocity, g is the acceleration due to gravity, and h is the height, we can calculate that the minimum speed needed is approximately 2.9 m/s.

The conservation of energy principle states that energy cannot be created or destroyed, only transferred or transformed from one form to another. In this case, the initial kinetic energy of the puck is transformed into potential energy as it gains height on the ramp. The formula v = √(2gh) is derived from the conservation of energy principle, where the potential energy gained is equal to mgh and the kinetic energy is equal to 1/2mv^2. By equating the two, we get mgh = 1/2mv^2, which simplifies to v = √(2gh).

The minimum speed needed for a 100 g puck to make it to the top of a frictionless ramp that is 3.0 m long and inclined at 20° is approximately 2.9 m/s.

The coordinates of the center of the circle x^2 + 2x + y^2 - 4y = 12 are (-1, 2).

To determine the coordinates of the center of the circle defined by the equation x^2 + 2x + y^2 - 4y = 12, we need to complete the square for both the x and y terms.

Starting with the x terms, we can add (2/2)^2 = 1 to both sides of the equation to get:

x^2 + 2x + 1 + y^2 - 4y = 12 + 1

Simplifying:

(x + 1)^2 + (y - 2)^2 = 13

Comparing this to the standard form of a circle, (x - h)^2 + (y - k)^2 = r^2, we see that the center of the circle is (-1, 2) and the radius is sqrt(13).

a) For the function f(x) = sin(x), the Taylor polynomials T2 and T3 centered at a = 0 can be calculated as follows:

The Taylor polynomial of degree 2 for f(x) = sin(x) centered at x = 0 is:

T2(x) = f(0) + f'(0)x + (f''(0)/2!)x^2

= sin(0) + cos(0)x + (-sin(0)/2!)x^2

= x

The Taylor polynomial of degree 3 for f(x) = sin(x) centered at x = 0 is:

T3(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3

= sin(0) + cos(0)x + (-sin(0)/2!)x^2 + (-cos(0)/3!)x^3

= x - (1/6)x^3

Therefore, the Taylor polynomials T2 and T3 centered at x = 0 for the function f(x) = sin(x) are T2(x) = x and T3(x) = x - (1/6)x^3.

T2(x) = f(5) + f'(5)(x - 5) + (f''(5)/2!)(x - 5)^2

= (5^4 - 2(5)) + (4(5^3) - 2)(x - 5) + (12(5^2))(x - 5)^2

= 545 + 190(x - 5) + 150(x - 5)^2

The Taylor polynomial of degree 3 for f(x) = x^4 - 2x centered at x = 5 is:

T3(x) = f(5) + f'(5)(x - 5) + (f''(5)/2!)(x - 5)^2 + (f'''(5)/3!)(x - 5)^3

Our initial assumption that the square root of n is rational must be false, and we can conclude that the square root of 18 is irrational.

To prove that the square root of 18 is irrational using strong induction, we first need to state and prove a lemma:

Lemma: If n is a composite integer, then n has a prime factor less than or equal to the square root of n.

Proof of Lemma: Let n be a composite integer, and let p be a prime divisor of n. If p is greater than the square root of n, then p*q > n for some integer q, which contradicts the assumption that p is a divisor of n. Therefore, p must be less than or equal to the square root of n.

Now we can prove that the square root of 18 is irrational:

Base Case: For n = 2, the square root of 18 is clearly irrational.

Inductive Hypothesis: Assume that for all k < n, the square root of k is irrational.

Inductive Step: We want to show that the square root of n is irrational. Suppose for the sake of contradiction that the square root of n is rational. Then we can write the square root of n as p/q, where p and q are integers with no common factors and q is not equal to 0. Squaring both sides, we get:

n = p^2 / q^2

Multiplying both sides by q^2, we get:

n*q^2 = p^2

This shows that n*q^2 is a perfect square, and since n is not a perfect square, q^2 must have a prime factorization that includes at least one prime factor raised to an odd power. Let r be the smallest prime factor of q. Then we can write:

q = r*m

where m is an integer. Substituting this into the previous equation, we get:

nr^2m^2 = p^2

Since r is a prime factor of q, it is also a prime factor of p^2. Therefore, r must be a prime factor of p. Let p = r*k, where k is an integer. Substituting this into the previous equation, we get:

nm^2r^2 = r^2*k^2

Dividing both sides by r^2, we get:

n*m^2 = k^2

This shows that k^2 is a multiple of n. By the lemma, n must have a prime factor less than or equal to the square root of n. Let s be this prime factor. Then s^2 is a factor of n, and since k^2 is a multiple of n, s^2 must also be a factor of k^2. This implies that s is also a factor of k, which contradicts the assumption that p and q have no common factors.

The cross product of two vectors using the distributive property:

(u - 7v) × (u + 7v) = u × u + u × 7v - 7v × u - 7v × 7v

Also, cross product is anti-commutative. Specifically, the cross product of v × w is equal to the negative of the cross product of w × v. So, we can simplify the expression as follows:

(u - 7v) × (u + 7v) = u × 7v - 7v × u - 7(u × 7v)

Now, using u × v = ⟨7, 6, 0⟩ to evaluate the cross products:

u × 7v = 7(u × v) = 7⟨7, 6, 0⟩ = ⟨49, 42, 0⟩

7v × u = -u × 7v = -⟨7, 6, 0⟩ = ⟨-7, -6, 0⟩

Substituting these values into the expression:

(u - 7v) × (u + 7v) = ⟨0, 7u_2 - 6u_3, 7u_3 - 6u_2⟩ - 7⟨7, 6, 0⟩ - 7⟨-7, -6, 0⟩

= ⟨0, 7u_2 - 6u_3, 7u_3 - 6u_2⟩ - ⟨49, 42, 0⟩ + ⟨49, 42, 0⟩

= ⟨-49, -7u_2 + 6u_3, -7u_3 + 6u_2⟩

Part A:Two equivalent expressions to describe the perimeter of Tara's garden including the walkway are:

2(6 + w) + 2(10 + w) = 24 + 4w, where w is the width of the walkway.

The 2(6 + w) accounts for the two lengths of the rectangle, and 2(10 + w) accounts for the two widths of the rectangle. Simplify the expression to 4w + 24 to give the total perimeter of the garden. The other expression is:

20 + 2w + 2w + 12 = 2w + 32

Part B:To check the equivalence of the two expressions from Part A, we could simplify both expressions, as shown below.2(6 + w) + 2(10 + w) = 24 + 4w.

Simplifying the expression will yield:2(6 + w) + 2(10 + w)

= 2(6) + 2(10) + 4w2(6 + w) + 2(10 + w)

= 32 + 4w2(6 + w) + 2(10 + w)

= 4(w + 8)

Similarly, we can simplify 20 + 2w + 2w + 12 = 2w + 32, which yields:20 + 2w + 2w + 12 = 4w + 32

Part C:If the walkway is 2.5ft wide, the total perimeter of Tara's garden, including the walkway, is:

2(6 + 2.5) + 2(10 + 2.5)

= 2(8.5) + 2(12.5)

= 17 + 25

= 42ft.

We can find two equivalent expressions to describe the perimeter of Tara's garden, including the walkway. We can use the expression 2(6 + w) + 2(10 + w) and simplify it to 4w + 24.

The other expression can be obtained by adding the length of all four sides of the garden. We can check the equivalence of both expressions by simplifying each expression and verifying if they are equal.

We can calculate the total perimeter of Tara's garden, including the walkway, by using the formula 2(6 + 2.5) + 2(10 + 2.5), which gives us 42ft as the answer.

Thus, at x ≈ 1.4142, the tangent line to the graph of y = x + 2/x is horizontal.

To find the x value where the tangent line of the graph y = x + 2/x is horizontal, we need to determine when the first derivative of the function is equal to 0.

This is because the slope of the tangent line is represented by the first derivative, and a horizontal line has a slope of 0.

First, let's find the derivative of y = x + 2/x with respect to x. To do this, we can rewrite the equation as y = x + 2x^(-1).

Now, we can differentiate:
y' = d(x)/dx + d(2x^(-1))/dx = 1 - 2x^(-2)

Next, we want to find the x value when y' = 0:
0 = 1 - 2x^(-2)

Now, we can solve for x:
2x^(-2) = 1
x^(-2) = 1/2
x^2 = 2
x = ±√2

Since we are looking for a positive x value, we can disregard the negative solution and round the positive solution to four decimal places:
x ≈ 1.4142

The area of the region enclosed by the curves  y = √x, y = x² and x = 2 is 4√2/4  - 8/3

To sketch the finite region enclosed by the curves y = √x, y = x² and x = 2 we can first plot the two functions and the vertical line

The region we are interested in is the shaded area between the two curves and to the left of the line x=2. To find the area of this region, we can integrate the difference between the two functions with respect to x over the interval [0] [2]

[tex]\int_0^2(\sqrt{x} -x^2)dx[/tex]

Evaluating this integral, we get:

= [tex][\frac{2}{3} x^{\frac{3}{2}}-\frac{1}{3} x^3]_0^2[/tex]

= [tex]\frac{2}{3} (2)^\frac{3}{2} - \frac{1}{3}(2)^3-0[/tex]

= 4√2/4  - 8/3

Therefore, the area of the region enclosed by the curves  y = √x, y = x² and x = 2 is 4√2/4  - 8/3

The given linear program can be solved using the simplex algorithm. The optimal solution is obtained by setting up the initial tableau and applying the simplex method. The optimal solution is x=100, y=0, and the maximum profit is $500. This means that the company should produce 100 units of x to maximize their profit, subject to the given constraints.

The given linear program is a maximization problem with three constraints. To solve this problem, we can use the simplex method, which involves converting the constraints to equations and setting up the initial tableau. The initial tableau for this problem is:

| Basic Variables | x | y | s1 | s2 | s3 | RHS |
|-----------------|---|---|----|----|----|-----|
| z               | 5 | 10| 0  | 0  | 0  | 0   |
| s1              | 1 | 0 | 1  | 0  | 0  | 100 |
| s2              | 0 | 1 | 0  | 1  | 0  | 80  |
| s3              | 2 | 4 | 0  | 0  | 1  | 400 |

We can see that the basic variables are s1, s2, and s3, and the non-basic variables are x and y. We can choose the most negative coefficient in the objective row, which is -5 for x, and pivot on the corresponding element in the tableau, which is 1 in the first row and first column. This results in the following tableau:

| Basic Variables | x  | y   | s1  | s2  | s3   | RHS   |
|-----------------|----|-----|-----|-----|------|-------|
| z               | 0  | 10  | -5  | 0   | 0    | 500   |
| s1              | 1  | 0   | 1   | 0   | 0    | 100   |
| s2              | 0  | 1   | 0   | 1   | 0    | 80    |
| s3              | 0  | 4   | -2  | 0   | 1    | 200   |

Now the basic variables are x, s2, and s3, and the non-basic variables are y and s1. We can see that the objective function has improved from 0 to 500, and the most negative coefficient in the objective row is now 0. We can conclude that the optimal solution has been reached, and it is x=100, y=0, with a maximum profit of $500.
Bn
The optimal solution to the given linear program is x=100, y=0, with a maximum profit of $500. This means that the company should produce 100 units of x to maximize their profit, subject to the given constraints. We can use the simplex method to solve linear programs like this one, by setting up the initial tableau and applying the pivot operations to improve the objective function. If the problem has multiple optimal solutions or is unbounded, we need to use additional techniques to determine the appropriate solution.

To find out how many miles apart the school and the park are, we need to convert the distance from kilometers to miles.

Given that there are 1.6 km in a mile, we can set up a conversion factor:

1 mile = 1.6 km

Now, we can calculate the distance in miles by dividing the distance in kilometers by the conversion factor:

Distance in miles = Distance in kilometers / Conversion factor

Distance in miles = 6 km / 1.6 km/mile

Simplifying the expression:

Distance in miles = 3.75 miles

Therefore, the school and the park are approximately 3.75 miles apart.

The range of weights of the sheep at the Southdown Sheep Farm is 170 pounds. This indicates the difference between the highest weight and the lowest weight among the sheep.

In the given list of weights, the highest weight is 275 pounds (the maximum value) and the lowest weight is 105 pounds (the minimum value). By subtracting the minimum weight from the maximum weight, we can calculate the range: 275 - 105 = 170 pounds.

The range is a measure of dispersion and provides information about the spread of the data. In this case, it tells us the maximum difference in weight among the sheep at the farm. By knowing the range, we can understand the variability in sheep weights, which may have implications for their health, nutrition, or breeding practices.

It is an essential statistic for farmers and researchers in evaluating and managing their livestock. In this particular scenario, the range of weights at the Southdown Sheep Farm is 170 pounds.

To determine if the series 1+1/16+1/81+1/256+1/625+... is convergent or divergent the sum of the series exists and is finite, we can conclude that the series is convergent.

To determine if the series 1+1/16+1/81+1/256+1/625+... is convergent or divergent, we need to apply the convergence tests. The series is a geometric series with a common ratio of 1/4 (each term is one-fourth of the previous term). The formula for the sum of an infinite geometric series is a/(1-r), where a is the first term and r is the common ratio. In this case, a = 1 and r = 1/4.
Using the formula, we get:
sum = 1/(1-1/4) = 1/(3/4) = 4/3
Since the sum of the series exists and is finite, we can conclude that the series is convergent.

In deciding whether to insert company-designed danger symbols to denote the potential for electrocution, the writer's primary concern should be liability law.

This will be the correct option.

Why liability law is a writer's primary concern? Liability law or legal accountability is important for companies, and individuals may be held accountable for their activities.

These rules exist to shield consumers from businesses that are not up to par.

An individual's freedom to speak their thoughts is limited to prevent harm to others.

The symbol used for electrocution danger should be placed in the manual by the writer.

Electricians or people working in electrical fields require the warning symbol to be included in the manual to avoid accidents and keep them safe.

When writing a manual, the writer should be concerned about liability law, which ensures that the company is not held accountable if an accident occurs as a result of insufficient warning or instruction in the manual.

The writer's job in writing a manual is to provide instruction to the readers, which is why they must ensure that everything is done legally and safely so that they do not fall under liability law.

Therefore, the writer's primary concern should be liability law when considering whether to insert company-designed danger symbols to denote the potential for electrocution.
