Answer:

  3/2

Step-by-step explanation:

Finding the slope of a line on a graph is easier if you can identify places where the line crosses grid intersections. We see two of those to be ...

  (4, 1) and (6, 4)

The second of these points is 4-1 = 3 grid squares higher than the first point. It is also 6 -4 = 2 grid squares to the right. The slope is the ratio of these values:

  slope = "rise"/"run" = 3/2

The slope of the graphed line is 3/2.

Answer:

15.7 square feet

Step-by-step explanation:

To find the area of the garden we find the area of the rectangle and the area of the semicircle.

The area of the rectangle:

A=bh

A=(29)(20)

A=580ft^2

As shown in the picture, the width of the rectangle is 20 ft wide, which means that the diameter of the semicircle is also 20ft wide. The diameter is two times the radius, which means the radius of the semicircle is 10ft.

The area of a circle is represented by the equation: \(A=\pi r^{2}\)

A semicircle is half of a circle, therefore the equation to find the area of a semicircle is: \(A=\frac{1}{2}\pi r^{2}\)

Plugging our radius of 10ft in we get:

\(A=\frac{1}{2}\pi (10)\\ A=5\pi\)

We use 3.14 for our value of \(\pi\) to get:

\(A=5(3.14)\\A=15.7ft^{2}\)

Therefore, the area of the rose garden is 15.7 square feet.

Step-by-step explanation:

\( \frac{( - 2)}{( - 5x)} = 10 \\ \\ \frac{2}{5x} = 10 \\ \\ 2 = 10 \times 5x \\ 2 = 50x \\ \\ x = \frac{2}{50} \\ \\ x = \frac{1}{25} \)

Answer:

$3,745

Step-by-step explanation:

First, you have to calculate the price after the discount is applied:

Price of the car: $25,000

Discount: 18%

$25,000*18%= $4,500

$25,000-$4,500= $20,500

Second, you have to calculate the total amount she has to pay including the 7% tax:

$25,000*7%= $1,750

$25,000+$1,750= $26,750

Third, as the statement indicates that Ms. Eve had to put  14% of what she had to pay as down payment, you have to calculate the 14% of $26,750:

$26,750*14%= $3,745

According to this, Ms. Eve has to pay $3,745 for the down payment.

First, we need to set up our two equations. For the picture of this scenario, there is one length (L) and two widths (W) because the beach removes one of the lengths. We will have a perimeter equation and an area equation.

P = L + 2W

A = L * W

Now that we have our equations, we need to plug in what we know, which is the 40m of rope.

40 = L + 2W

A = L * W

Then, we need to solve for one of the variables in the perimeter equation. I will solve for L.

L = 40 - 2W

Now, we can substitute the value for L into L in the area equation and get a quadratic equation.

A = W(40 - 2W)

A = -2W^2 - 40W

The maximum area will occur where the derivative equals 0, or at the absolute value of the x-value of the vertex of the parabola.

V = -b/2a

V = 40/2(2) = 40/4 = 10

Derivative:

-4w - 40 = 0

-4w = 40

w = |-10| = 10

To find the other dimension, use the perimeter equation.

40 = L + 2(10)

40 = L + 20

L = 20m

Therefore, the dimensions of the area are 10m by 20m.

Hope this helps!

Answer:

Width: 10 m

Length: 20 m

Step-by-step explanation:

Hi there!

Let w be equal to the width of the enclosure.

Let l be equal to the length of the enclosure.

1) Construct equations

\(A=lw\) ⇒ A represents the area of the enclosure.

\(40=2w+l\) ⇒ This represents the perimeter of the enclosure. Normally, P=2w+2l, but because one side isn't going to use any rope (sandy beach), we remove one side from this equation.

2) Isolate one of the variables in the second equation

\(40=2w+l\)

Let's isolate l. Subtract 2w from both sides.

\(40-2w=2w+l-2w\\40-2w=l\)

3) Plug the second equation into the first

\(A=lw\\A=(40-2w)w\\A=40w-2w^2\\A=-2w^2+40w\)

Great! Now that we have a quadratic equation, we can do the following:

4) Solve for w

\(A=-2w^2+40w\)

Factor out -2w

\(A=-2w(w-20)\)

For A to equal 0, w=0 or w=20.

The average of 0 and 20 is 10, so the width that will max the area is 10 m.

5) Solve for l

\(40=2w+l\)

Plug in 10 as w

\(40=2(10)+l\\40=20+l\\l=20\)

Therefore, the length of 20 m will max the area.

I hope this helps!

The specific numerical solution will depend on the number of firms in the market and their behavior.

In a Stackelberg version of monopolistic competition, there is a leader firm that sets its output first, and all the other firms in the market act as followers and choose their outputs simultaneously.

Suppose there are "n" firms in the market, with the first firm denoted as the leader. Let's assume that each firm has a constant marginal cost of $10 per unit. Then, the leader firm's profit-maximizing output level can be found by solving the following problem:

max (30-Q1-Q2-...-Qn)Q1 - 10Q1

subject to Q1 >= 0

where Q1 is the output level of the leader firm, and Q2, Q3, ..., Qn are the output levels of the follower firms.

Taking the first-order condition by differentiating with respect to Q1 and setting it equal to zero, we get:

d/dQ1 [(30-Q1-Q2-...-Qn)Q1 - 10Q1] = 0

Simplifying this expression, we get:

30 - Q1 - Q2 - ... - Qn - 2Q1 = 0

Solving for Q1, we get:

Q1 = (30 - Q2 - ... - Qn)/3

This equation gives us the leader firm's profit-maximizing output level as a function of the follower firms' output levels.

Now, let's consider the follower firms' profit-maximizing output levels. Since each follower firm is a price-taker, its profit-maximizing output level can be found by equating marginal cost to market price, which is equal to the market demand curve divided by the total quantity produced by all firms in the market. Therefore, the profit-maximizing output level of the jth follower firm can be expressed as:

Qj* = (1/n) * (30 - Q1 - Q2 - ... - Qj-1 - Qj+1 - ... - Qn - 10)

where Qj* is the follower firm's profit-maximizing output level, and j = 2, 3, ..., n.

Using these expressions for the leader and follower firms' profit-maximizing output levels, we can solve for the equilibrium outputs and profits in the Stackelberg version of monopolistic competition. However, the specific numerical solution will depend on the number of firms in the market and their behavior.

Answer:

To solve this problem, we can use the formula for the slope of a line: slope = (y2 - y1)/(x2 - x1).

Plugging in the given values, we get: slope = (9 - v)/(-4 - (-7)).

We can simplify this to: slope = (9 - v)/3.

Since the slope is given as 6, we can set this expression equal to 6 and solve for v:

6 = (9 - v)/3

Multiplying both sides by 3 gives us: 18 = 9 - v

Adding v to both sides gives us: 18 + v = 9

Subtracting 9 from both sides gives us: v = 9 - 18

Finally, we can simplify this to: v = -9

So the value of v is -9.

Answer:

-9

Step-by-step explanation:

(9 - v)/(-4+7)= 6

9 - v = 18

-v = 9

v = -9

We can say that the probability which is more than 192 of the confidence intervals cover the true proportions i.e, P(X > 192) is 0.9452.

Given: Confidence interval = 95%

We need to find the probability that more than 192 of the confidence intervals cover the true proportions.

P(X > 192) = ?

We know that the sample proportion follows the Normal distribution as n is large.

According to the Central Limit Theorem, the sample proportion follows the Normal distribution with mean and standard deviation as shown below:

μp = pσp = √((pq/n))

Here, p and q are population proportions and p + q = 1.

We do not know the population proportion, p or q, but we can assume that p = q = 0.5 in case we do not have any prior knowledge of p and q.

Now, we standardize the Normal distribution using z-score:

Z = (X - μp) / σp

Z = (X - np) / √((npq/n))

Here, X is the number of confidence intervals that cover the true proportions.

The sample proportion is computed as:

p = X / n

Here, n is the number of samples (towns).

Now, the z-score can be written as:

Z = (X - np) / √((npq/n)) > Z

= (192 - 200 × 0.5) / √((200 × 0.5 × 0.5/200))

= -1.6

P(Z > -1.6) = 0.9452 [from z-table]

Therefore, the probability that more than 192 of the confidence intervals cover the true proportions is P(X > 192)

= 1 - P(X ≤ 192) > 1 - P(Z ≤ -1.6) > 1 - 0.0548

= 0.9452

The corresponding differential element, rewrite the integral in terms of the new variable, integrate with respect to the new variable, replace the new variable with the original variable, and simplify the expression to find the solution.

To perform u-substitution with indefinite integrals, follow these steps:

Identify a suitable substitution: Look for a part of the integrand that resembles the derivative of a function. Choose a variable u to substitute for that part.

Calculate du: Take the derivative of u with respect to the original variable. This will help us express du in terms of the original variable.

Rewrite the integral: Substitute the chosen variable and du in the original integral, replacing the part to be substituted with u and the corresponding differential element du.

Integrate with respect to u: Treat the integral as a new integral with respect to u. Evaluate the integral using the rules of integration.

Replace u with the original variable: Rewrite the result of the integration in terms of the original variable.

Simplify and solve: If necessary, simplify the expression further or perform additional algebraic manipulations to obtain the final result.

Let's illustrate these steps with an example:

Consider the integral ∫(2x + 3)² dx.

Identify a suitable substitution: Let u = 2x + 3.

Calculate du: Take the derivative of u with respect to x: du/dx = 2. Rearrange the equation to solve for du: du = 2 dx.

Rewrite the integral: In terms of u and du, the integral becomes ∫u² (du/2).

Integrate with respect to u: Treat the integral as a new integral with respect to u: (1/2) ∫u² du = (1/2) * (u³/3) + C, where C is the constant of integration.

Replace u with the original variable: Substitute back u = 2x + 3 in the result: (1/2) * ((2x + 3)³/3) + C.

Simplify and solve: Further simplify the expression if necessary to obtain the final result.

In summary, to perform u-substitution with indefinite integrals, identify a suitable substitution, calculate the corresponding differential element, rewrite the integral in terms of the new variable, integrate with respect to the new variable, replace the new variable with the original variable, and simplify the expression to find the solution.

Finding the square root of non-perfect square numbers typically results in an irrational number, which has a non-repeating and non-terminating decimal representation.

Finding the square root of a number involves determining the value that, when multiplied by itself, gives the original number. Here are a few methods to find the square root:

Prime Factorization: This method involves breaking down the number into its prime factors. Pair the factors in groups of two, and take one factor from each pair. Multiply these selected factors to find the square root. For example, to find the square root of 36, the prime factors are 2 * 2 * 3 * 3. Taking one factor from each pair (2 * 3), we get 6, which is the square root of 36.

Estimation: Approximate the square root using estimation techniques. Find the perfect square closest to the number you want to find the square root of and estimate the value in between. Refine the estimate using successive approximations if needed. For example, to find the square root of 23, we know that the square root of 25 is 5. Therefore, the square root of 23 will be slightly less than 5.

Using a Calculator: Most calculators have a square root function. Simply input the number and use the square root function to obtain the result.

It's important to note that finding the square root of non-perfect square numbers typically results in an irrational number, which has a non-repeating and non-terminating decimal representation.
