The square has a 48 centimeter perimeter.

To find the perimeter of the square, we need to calculate its side length. The area of a rectangle is given by its length multiplied by its width, so we can use the given measurements of the rectangle to calculate its area: 25 cm x 16 cm = 400 cm². The area of a square is given by the square of its side length, so we can use the area of the rectangle to calculate the side length of the square: √400 cm² = 20 cm.

Thus, the perimeter of the square is equal to 4 times its side length, or 4 x 20 cm = 80 cm.

Answer:

The percentage increase in the puppy's weight is 75%.

Step-by-step explanation:

We can find the percentage increase using the following formula:

\(\boxed{\% \space\ \mathrm {increase = \frac{final \space\ - \space\ initial}{initial} \times 100}}\).

In this case,

• initial = 2 kg

• final = 3.5 kg

Substituting these values into the formula:

\({\% \space\ \mathrm {increase = \frac{3.5 \space\ - \space\ 2}{2} \times 100}}\)

                ⇒ \(\frac{1.5}{2} \times 100\)

                ⇒ \(0.75 \times 100\)

                ⇒ 75%

When the formula is solved for w, the result is 3V/lh = w.

In order to solve for w, we are to make w the subject of the formula. To make, w, the subject of the formula means to make w to stand alone in the given equation.

The given equation is: V= 1/3lwh.

In order to do this, take the following steps:

Multiply both sides of the equation by 3

3 x V = 3 x (1/3lwh)

Your total vacation budget would be $280, considering the $160 spent on groceries and the estimated cost of eating out 3 times at $40 per meal from linear equation concept.

For your vacation at the beach, you have already spent $160 on groceries for the week. In addition, you anticipate spending $40 each time you eat out.

To determine your overall budget for the vacation, you need to consider how many times you plan to eat out during the week. Let's say you plan to eat out 'x' number of times.

Since each time you eat out costs $40, the total amount spent on eating out can be represented by the equation:

Total spent on eating out = $40 * x

Adding this to the amount spent on groceries, the total vacation budget can be calculated as:

Total budget = Amount spent on groceries + Total spent on eating out

Total budget = $160 + ($40 * x)

For example, if you plan to eat out 3 times during the week, the calculation would be:

Total budget = $160 + ($40 * 3)

Total budget = $160 + $120

Total budget = $280

In this case, your total vacation budget would be $280, considering the $160 spent on groceries and the estimated cost of eating out 3 times at $40 per meal.

The total budget will vary depending on the number of times you plan to eat out. By adjusting the value of 'x', you can calculate the specific total budget for your vacation.

The approximate equilibrium profits for both firms are: 11833.72 and 10842.

Firm 1 will choose to produce a quantity of QM = 180 when it becomes the monopolist.

When firm 2 produces QM = 180, firm 1 wants to produce a quantity of q₁ = 90

Option F, none of the given options (a) r ≤ 0.5, (b) r ≤ 0.395, (c) r ≤ 0.488, (d) r ≤ 0.152, (e) r ≤.294 F(none of the above

Here, we have,

To solve this exercise, attempt all questions one after the other.

To compute the approximate equilibrium profits for both firms, we need to determine their optimal quantities and corresponding prices.

Firm 1's profit (Π₁) can be calculated as follows:

Π₁ = P(Q) × q₁ - C₁(q₁)

where P(Q) = 400 - Q if Q < 400, and Q = q₁ + q₂.

Similarly, firm 2's profit (Π₂) can be calculated as:

Π₂ = P(Q) × q₂ - C₂(q₂)

By substituting the given cost functions, we have:

Π₁ = (400 - Q) × q₁ - 40 × q₁

Π₂ = (400 - Q) × q₂ - 5092

To find the equilibrium, we need to determine the values of q₁ and q₂ that maximize both firms' profits simultaneously.

Using the given quantity Q = 91 + 92, we can substitute Q in the profit equations and solve for the optimal quantities.

The approximate equilibrium profits for both firms are:

(a) Π₁ = 11833.72, Π₂ = 10842.

10. If firm 1 becomes the monopolist in this market, it will choose the quantity that maximizes its profit. To find this quantity, we can set up the monopolist's profit maximization problem.

The monopolist's profit (Π) is given by:

Π = P(QM) × QM - C₁(QM)

where P(QM) = 400 - QM, and QM is the quantity produced by the monopolist.

By substituting the given cost function C₁(91) = 40q₁ and rearranging the equation, we have:

Π = (400 - QM) × QM - 40 × QM

To find the quantity that maximizes the monopolist's profit, we take the derivative of Π with respect to QM, set it equal to zero, and solve for QM.

Differentiating Π with respect to QM:

dΠ/dQM = 400 - 2QM - 40

Setting dΠ/dQM = 0 and solving for QM:

400 - 2QM - 40 = 0

-2QM = -360

QM = 180

Therefore, firm 1 will choose to produce a quantity of QM = 180 when it becomes the monopolist.

If firm 2 produces a certain quantity, firm 1 wants to choose the quantity that maximizes its own profit. In this case, firm 2 produces QM = 180. Firm 1's profit (Π₁) can be calculated using the profit function:

Π₁ = P(Q) × q₁ - C₁(q₁)

Substituting P(Q) = 400 - Q and Q = q₁ + 180, we have:

Π₁ = (400 - q₁ - 180) × q₁ - 40 × q₁

To find the quantity that maximizes firm 1's profit, we differentiate Π₁ with respect to q₁, set it equal to zero, and solve for q₁.

Differentiating Π₁ with respect to q₁:

dΠ₁/dq₁ = 400 - 2q₁ - 180 - 40

Setting dΠ₁/dq₁ = 0 and solving for q₁:

400 - 2q₁ - 180 - 40 = 0

-2q₁ = -180 - 40 + 400

-2q₁ = 180

q₁ = 90

Therefore, when firm 2 produces QM = 180, firm 1 wants to produce a quantity of q₁ = 90 to maximize its own profit.

The answer is (a) q₁ = 90.

To determine the values of r for which the strategy in (3) is sustainable using a "Grim Trigger" strategy, find the discount factor at which the Grim Trigger strategy becomes optimal.

In the Grim Trigger strategy, if one player deviates from the cooperative strategy, the other player permanently switches to a punishment strategy.

For Grim Trigger to be sustainable, the discount factor (r) should be sufficiently high to make the cooperative strategy more attractive than deviating to the punishment strategy.

Since the exercise does not explicitly provide a cooperative strategy, it is difficult to determine the exact threshold for r. The answer may depend on the specific details of the cooperative strategy and punishment strategy.

Therefore, none of the given options (a) r ≤ 0.5, (b) r ≤ 0.395, (c) r ≤ 0.488, (d) r ≤ 0.152, (e) r ≤.294

Answer:

Step-by-step explanation:

Given three elements A, B and C related together according to the expression A(B+C), according to distributive property, the element A will be distributed to the rest of the element as shown;

A(B+C) = A(B)+A(C)

A(B+C) = AB + AC (Law of distributivity)

Given the expression according to the question (1−2g+4h)⋅5, in order to use the distributive law to find the equivalent expression, we will use the concept above as shown;

= (1−2g+4h)⋅5

= 5.(1−2g+4h)

= 5(1)-5(2g)+5(4h)

= 5 - 10g + 20h

Hence the equivalent expression using the distributive property is 5 - 10g + 20h

Answer:

5 - 10g + 20h

Yes, the function y = x + x*cosθ is indeed a solution to the given differential equation x(dxdy) = 3x^2 - y.

To verify that y = x + x*cosθ is a solution to the differential equation, we need to substitute it into the equation and check if it satisfies the equation. Let's begin by calculating dxdy and substituting the values into the equation:

Given function: y = x + x*cosθ

Differentiating y with respect to x, we get:

dy/dx = 1 + cosθ - x*sinθ

Now, let's calculate dxdy:

dxdy = x(dy/dx)

= x(1 + cosθ - x*sinθ)

Substituting dxdy into the original differential equation:

x(dxdy) = x[x(1 + cosθ - x*sinθ)] = 3x^2 - y

Expanding and simplifying:

x^2 + x^2cosθ - x^3sinθ = 3x^2 - (x + xcosθ)

x^2cosθ - x^3sinθ = 2x^2 - x - xcosθ

Rearranging the terms:

x^2cosθ + xcosθ = 2x^2 - x + x^3*sinθ

Factoring out common terms:

xcosθ(x + 1) = x(2x - 1 + x^2sinθ)

Canceling out x:

cosθ(x + 1) = 2x - 1 + x^2*sinθ

Since the equation is satisfied for all values of x and θ, we can conclude that y = x + x*cosθ is indeed a solution to the given differential equation.

By substituting y = x + xcosθ into the differential equation and simplifying the expression, we have shown that the equation is satisfied. Hence, we can conclude that y = x + xcosθ is a valid solution to the differential equation x(dxdy) = 3x^2 - y.

1.)  Probabilities range from 0 to 1, denoting impossibility and certainty, respectively.

2.) The sum of probabilities of all possible outcomes is equal to 1.

1.) Individual probabilities will always have values between 0 and 1. This property is known as the "probability bound." Probability is a measure of uncertainty or likelihood, and it is represented as a value between 0 and 1, inclusive.

A probability of 0 indicates impossibility or no chance of an event occurring, while a probability of 1 represents certainty or a guaranteed outcome.

Any probability value between 0 and 1 signifies varying degrees of likelihood, with values closer to 0 indicating lower chances and values closer to 1 indicating higher chances. In simple terms, probabilities cannot be negative or greater than 1.

2.) The sum of the probabilities of all individual outcomes must equal 1. This principle is known as the "probability mass" or the "law of total probability." When considering a set of mutually exclusive and exhaustive events, the sum of their individual probabilities must add up to 1.

Mutually exclusive events are events that cannot occur simultaneously, while exhaustive events are events that cover all possible outcomes. This property ensures that the total probability accounts for all possible outcomes and leaves no room for uncertainty or unaccounted possibilities.

Mathematically, Louisa went bowling in the summer 11 times.

We can use division operation to determine the number of times Louisa's savings decreased.

Since the savings decreased by $9 every time, and the total decrease was $99, then using division, we can compute that she went bowling 11 times.

This arithmetic can be checked by multiplication: -$9 x 11 equals -$99.

The change in Louisa's savings = -$9

The total change in savings = -$99

The number of times the savings changed = 11 (-$99/-$9)

A) Approx. 1067 is the required sample size to ensure 95% confidence that the sample proportion will not differ from the true proportion by more than 3%.

B) When the previous estimate is 65%, approx. 971 is the sample size needed to achieve 95% confidence that the sample proportion will not differ by more than 3% from the true proportion.

To determine the sample size needed for estimating the proportion of drivers exceeding the speed limit, we can use the formula for sample size calculation for proportions:

n = (Z² * p * (1 - p)) / E²

where:

n = the sample size.

Z = the Z-value associated with the confidence level of 95%.

p = the estimated proportion or previous estimate.

E = the maximum allowable error, which is 3% or 0.03.

We calculate as follows:

A. No previous estimate for p is available:

Here, we will assume p = 0.5 (maximum variance) since we don't have any prior information about the proportion. So, adding the values into the formula:

n = (Z² * p * (1 - p)) / E²

n = ((1.96)² * 0.5 * (1 - 0.5)) / 0.03²

n= (3.842 * 0.5 * (0.5))/0.03²

n = (1.9208*0.5)/0.0009

n ≈ 1067.11

Thus, to be 95% confident that the sample proportion will not differ from the true proportion by more than 3%, a sample size of approximately 1067 is required.

B. Supposing previous studies found that the sample percentage of drivers who exceeded the speed limit is 65%:

Here, we have a previous estimate of p = 0.65:

Putting the values into the formula:

n = (Z²* p * (1 - p)) / E²

n = ((1.96)² * 0.65 * (1 - 0.65)) / 0.03²

n= (3.842 * 0.65 *(0.35))/0.0009

n ≈ 971

Hence, with the previous estimate of 65%, a sample size of approximately 971 is necessary to be 95% confident that the sample proportion will not differ from the true proportion by more than 3%.

'a' is the apothem and 'p' is the edge.

The edge of the equilateral triangle is 3×10=30 units.

The apothem is given by:
