The condition for the first dark fringe through a single slit of width w is when the path difference between the light waves at the edges of the slit equals a half wavelength= (λ/2).

This can be expressed mathematically as:
w * sin(θ) = (m + 1/2) * λ, where m = 0 for the first dark fringe, w is the slit width, θ is the angle of the dark fringe from the central maximum, and λ is the wavelength of light.
When light passes through a single slit, it diffracts and creates an interference pattern with alternating bright and dark fringes on a screen. The dark fringes occur when light waves from the edges of the slit interfere destructively, which means their path difference must be an odd multiple of half a wavelength (λ/2).
For the first dark fringe, we set m = 0 in the equation:
w * sin(θ) = (0 + 1/2) * λ
So, the condition for the first dark fringe is:
w * sin(θ) = λ/2

Hence, The condition for the first dark fringe through a single slit of width w is when the path difference between the light waves at the edges of the slit equals a half wavelength (λ/2). This can be represented by the equation w * sin(θ) = λ/2.

Answer:

if the length is longer than width then it means its a rectangle...and equation of the area is length×breath ... therefore 270=x×3x

Answer:

Step-by-step explanation

Given

The perimeter of a rectangular painting =348 centimeter

the width of the painting=82cm

Solution

Perimeter of the rectangular painting=2(length+width)

2(Length +width)=348

2(Length+82)=348

2l+164=348

2l=348-164

2l=184

Length=184/2

So length =92cm.

An inequality is a mathematical statement that uses symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to) to compare two quantities. In real life, we can use inequalities to describe a wide range of situations. For example, let's say you are buying groceries and you have a budget of $50. You could use the inequality  total cost of groceries < $50 to describe your situation. This inequality states that the total cost of the groceries must be less than $50, or you will exceed your budget.

In another real life situation, let's say you are training for a race and you want to run a certain distance in a specific amount of time. You could use the inequality distance > speed × time to describe your goal. This inequality states that the distance you run must be greater than the product of your speed and the time it takes you to complete the race. Inequality statements can also be used in social science and economics. For example, we can use an inequality to describe the income distribution in a society. We could say that the top 10% of earners have an income greater than the bottom 90% of earners, using the inequality top 10% income > bottom 90% income.

In summary, inequalities can be used to describe real life situations by comparing two quantities using symbols such as <, >, ≤, or ≥. We can use inequalities to describe a wide range of situations, from grocery shopping to income distribution.

The specific solution to the given ODE with the initial conditions is:

y(t) = (8.5π - 8.5t) \(e^{(-2t)\) + 8.5(t - π)

To solve the given ordinary differential equation (ODE) with the initial conditions, we can use the method of undetermined coefficients.

The characteristic equation for the homogeneous part of the ODE is:

r² + 4r + 4 = 0

Solving this quadratic equation, we find a repeated root:

(r + 2)² = 0

r + 2 = 0

r = -2

Since we have a repeated root, the general solution to the homogeneous part is:

\(y_{h(t)\)= (C₁ + C₂t) \(e^{(-2t)\)

Next, we need to find a particular solution to the non-homogeneous part of the ODE. We assume a particular solution in the form:

\(y_{p(t)\) = A(t - π)

Taking the derivatives:

\(y'_{p(t)\)  = A

\(y''_{p(t)\) = 0

Substituting these derivatives into the ODE:

0 + 4A + 4A(t - π) = 68(t - π)

Simplifying:

8A(t - π) = 68(t - π)

8A = 68

A = 8.5

Therefore, the particular solution is:

\(y_{p(t)\) = 8.5(t - π)

The general solution to the ODE is the sum of the homogeneous and particular solutions:

\(y(t) = y_{h(t)} + y_{p(t)\)

= (C₁ + C₂t) \(e^{(-2t)\) + 8.5(t - π)

To find the values of C₁ and C₂, we apply the initial conditions:

y(0) = 0

0 = (C₁ + C₂(0)) \(e^{(-2(0))\) + 8.5(0 - π)

0 = C₁ - 8.5π

C₁ = 8.5π

y'(0) = 0

0 = C₂ \(e^{(-2(0))\) + 8.5

0 = C₂ + 8.5

C₂ = -8.5

Therefore, the specific solution to the given ODE with the initial conditions is:

y(t) = (8.5π - 8.5t)  + 8.5(t - π)

(a) To find the probability that no one enters the casino between 12:00 and 12:05, we can use the Poisson distribution, where λ = the expected number of arrivals during the given time interval. In this case, λ = (1/2) x 5 = 2.5 (since the rate is 1 person every 2 minutes, and the time interval is 5 minutes). Therefore, the probability of no one entering during this time is:

P(0 arrivals) = (e^(-2.5) x 2.5^0) / 0! ≈ 0.0821

(b) To find the probability that at least 4 people enter the casino during the 5-minute interval, we can again use the Poisson distribution. We want to find the probability of 4, 5, or more arrivals, so we can add up the probabilities of each of these events. Using λ = 2.5 again, we get:

P(4 arrivals or more) = P(X ≥ 4) = Σ(2.5^k x e^-2.5 / k!) from k=4 to infinity

Using a calculator or computer program, we can find that P(X ≥ 4) ≈ 0.0363.

(c) To find the probability that at least one person entered the casino in each of at least 3 of these 5 minutes, we can use the inclusion-exclusion principle. First, we find the probability that at least one person entered the casino during all 5 minutes:

We know that the area of a rectangle is

\(A= w \times l\)

Where \(w\) is width and \(l\) is length.

We know by given that \(l= 7 \ in\) and \(A= 25 \ in^{2}\), replacing these values and solving for \(w\), we have

\(25=7w\) (this is the equation used to solve the problem).

\(w=\frac{25}{7} \approx 3.6 \ in\)

Answer:

The equation is Area = length × width.

The width is approximately 3.57 inches.

Step-by-step explanation:

Door sign length, l = 7 inches

Area, A = 25 square inches

Width (w) is unknow.

Since the area is the product of the length and the width,

A = l×w

25 = 7×w

Dividing both sides by 7

w = 25/7

Answer:

Step-by-step explanation:

The height in which the weight is lifted is given as h = (P x δt) / m

The work done in lifting a weight is given by:

W = F x d

where F is the force required to lift the weight and d is the distance through which the weight is lifted.

The force required to lift the weight is equal to its weight, which is given by:

F = m x g

where m is the mass of the weight and g is the acceleration due to gravity.

The distance through which the weight can be lifted is given by:

d = h

where h is the height to which the weight is lifted.

If the energy used to lift the weight is given by p, and δt is the time taken to lift the weight, then the power used is given by:

P = p / δt

We can use the formula for power to express the force in terms of p and δt:

P = F x v = F x d / δt

F = P x δt / d

Substituting the expressions for F and d into the formula for work, we get:

W = (m x g x h) = (P x δt x h) / d

Solving for h, we get:

h = (P x δt x d) / (m x g)

Substituting the expression for d (d = h), we get:

h = (P x δt x h) / (m x g)

Multiplying both sides by (m x g), we get:

h x m x g = P x δt x h

Dividing both sides by (m x g), we get the final equation:

h = (P x δt) / m

Therefore, the height to which the weight can be lifted (h) in terms of p, δt, and m is given by:

h = (P x δt) / m

where P is the power used to lift the weight, δt is the time taken to lift the weight, and m is the mass of the weight.

To estimate the integral √(ln(2)) ln(x) dx within an accuracy of 0.01 using upper and lower sums for a uniform partition of the interval [1, e], we need to divide the interval into at least n subintervals. The answer is obtained by finding the minimum value of n that satisfies the given accuracy condition.

We start by determining the interval [1, e], where e is approximately 2.718. The function ln(x)^2 is increasing, meaning that its values increase as x increases. To estimate the integral, we use upper and lower sums with a uniform partition. In this case, the width of each subinterval is (e - 1)/n, where n is the number of subintervals.

To find the minimum value of n that ensures the accuracy condition S - S < 0.01, we need to evaluate the difference between the upper sum (S) and the lower sum (S) for the given partition. The upper sum is the sum of the maximum values of the function within each subinterval, while the lower sum is the sum of the minimum values.

Since ln(x)^2 is increasing, the maximum value of ln(x)^2 within each subinterval occurs at the right endpoint. Therefore, the upper sum can be calculated as the sum of ln(e)^2, ln(e - (e - 1)/n)^2, ln(e - 2(e - 1)/n)^2, and so on, up to ln(e - (n - 1)(e - 1)/n)^2.

Similarly, the minimum value of ln(x)^2 within each subinterval occurs at the left endpoint. Therefore, the lower sum can be calculated as the sum of ln(1)^2, ln(1 + (e - 1)/n)^2, ln(1 + 2(e - 1)/n)^2, and so on, up to ln(1 + (n - 1)(e - 1)/n)^2.

We need to find the minimum value of n such that the difference between the upper sum and the lower sum is less than 0.01. This can be done by iteratively increasing the value of n until the condition is satisfied. Once the minimum value of n is determined, we have the required number of subintervals for the given accuracy.
