Prove the following limit:
f(x) = ax^2
lim f(x) =a
x ->1

Answer: It has to be between 0.1 to 0.3

Step-by-step explanation:

Bose-Einstein condensation occurs and the ground state is significantly populated compared to the excited states.

a) To calculate the energy of the ground state, we need to use the formula E = (3/2)NkBT, where N is the number of particles, kB is Boltzmann's constant, and T is the temperature. Since we are dealing with Rb 87 atoms, which are bosons, we also need to consider the Bose-Einstein statistics. In this case, the energy of the ground state is given by Eo = (3/2)NkBTE, where TE is the Einstein temperature. Given that the number of atoms is N = 104, we can calculate Eo using the given values.

b) The Einstein temperature (TE) can be calculated using the formula TE = (2πℏ^2 / (mkB))^(2/3), where ℏ is the reduced Planck constant and m is the mass of the particle. We can calculate TE using the known values for Rb 87.

c) For T = 0.9TE, we can determine the number of atoms in the ground state by calculating the probability of occupation for that state using the Bose-Einstein distribution. The chemical potential (μ) represents the energy required to add an extra particle to the system. By comparing it to the ground state energy, we can determine how close the chemical potential is to the ground state energy. The number of atoms in the first excited states can also be calculated using the Bose-Einstein distribution.

d) By repeating parts (b) and (c) for a larger number of atoms (N = 106) but confined to the same volume, we can analyze the conditions under which the number of atoms in the ground state is much greater than the number in the first excited states. This comparison depends on the values of TE, T, and the number of atoms N.

Step-by-step explanation:

The function in vertex form that models the path of the stream is:

\(y = (-5/9)(x - 3)^2 + 5\)

A location where two or more straight lines or curves intersect is referred to as a vertex . A vertex in geometry is sometimes referred to as a corner or an intersection point. The phrase is frequently used to refer to the highest or lowest point on a curve or surface, the place where two lines intersect to make an angle, and the point where two sides of a polygon meet.

The vertex form of the equation of a parabola is given by:

\(y = a(x - h)^2 + k\)

where (h, k) represents the vertex of the parabola.

Using the given vertex and the point (6,0), we can find the value of "a" and plug it into the vertex form to get the equation of the parabolic path of the water stream.

Step 1: Find the value of "a"

Since the vertex is (3,5), we know that:

h = 3

k = 5

Using the point (6,0), we can find the value of "a" as follows:

\(0 = a(6 - 3)^2 + 5\)

\(0 = 9a + 5\)

\(9a = -5\)

\(a = -5/9\)

Step 2: Plug in the values of h, k, and a into the vertex form:

\(y = (-5/9)(x - 3)^2 + 5\)

Therefore, the function in vertex form that models the path of the stream is:

\(y = (-5/9)(x - 3)^2 + 5\)

Answer:

a = 17

c = 9

Step-by-step explanation:

2a + 3c = 61

3a + 5c = 96

3a = 96 - 5c   (solve for 'a'. Then you can substitute)  

a = 32 - \(\frac{5}{3}\) c

2(32 - \(\frac{5}{3}\)c) + 3c = 61     (Substitute)

64 - \(\frac{10}{3}\)c + 3c = 61        (\(\frac{10}{3}\) = 3 \(\frac{1}{3}\). So subtracting, adding a negative, leaves \(\frac{-1}{3}\))

-\(\frac{1}{3}\) c= -3  

c = 9

2a + 3(9) = 61

2a + 27 = 61

This is the equation that results from applying the Secant-Tangent Segment Theorem to the given figure.

Let's first define the terms and state the Secant-Tangent Segment Theorem.

1. Equation: A mathematical statement that shows the equality of two expressions.

2. Secant: A line that intersects a circle at two points.

3. Tangent: A line that touches a circle at only one point, without crossing it.

Secant-Tangent Segment Theorem: If a secant and a tangent are drawn from a point outside a circle, the product of the length of the secant segment and its external part is equal to the square of the length of the tangent segment.

Let's represent the given lengths as follows:
- Length of tangent segment = a
- Length of secant segment (inside the circle) = 12
- Length of the external part of the secant segment (outside the circle) = x

According to the Secant-Tangent Segment Theorem, the equation is:
(a)(a) = (12)(x + 12)

This simplifies to:
a² = 12x + 144

This is the equation that results from applying the Secant-Tangent Segment Theorem to the given figure.

To get rid of a fraction with a variable in the denominator, multiply both the numerator and denominator by that variable. This technique is very useful in simplifying complex fractions and solving equations involving fractions. To get rid of a fraction with a variable in the denominator

To get rid of a fraction with a variable in the denominator, you can use the technique of multiplying both the numerator and the denominator by the variable that is in the denominator. This will result in the variable canceling out from the denominator, leaving only the numerator.


Identify the variable in the denominator and the value of its exponent. For example, in the fraction 1/(x^2), the variable is x and the exponent is 2. Multiply both the numerator and denominator by the same power of the variable that is present in the denominator. In our example, multiply the numerator and denominator by x^2: (1 * x^2)/(x^2 * x^2). simplify the resulting expression by canceling out common terms between the numerator and denominator. In this case, x^2 in the numerator and denominator cancel out, leaving 1/(x^2) as the simplified answer without a variable in the denominator.

The value of a(t) is -1 and b(t) is 55 + \(e^t\)

No, the given equation y' - y = 55 + \(e^t\) is not in the standard form of a first-order linear differential equation.

In the method for solving a first-order linear differential equation, an integrating factor is a function used to transform the equation into a form that can be easily solved.

For an equation in the standard form y' + a(t)y = b(t), the integrating factor is defined as:

μ(t) = e^∫a(t)dt

To solve the equation, you multiply both sides of the equation by the integrating factor μ(t) and then simplify. This multiplication helps to make the left side of the equation integrable and simplifies the process of finding the solution.

To put it in standard form, we need to rewrite it as y' + a(t)y = b(t).

Comparing the given equation with the standard form, we can identify:

a(t) = -1

b(t) = 55 + \(e^t\)

Answer:

54.6 cm : B

Step-by-step explanation:

Mathematically the area of a rectangle is 2( l + b)

So in practical terms we only need the measure of two sides as we have 2 equal sides for a rectangle.

We can see that we have two right angles on each sides

Now to find b, we can use trigonometric ratios

For each of the rectangles, the diagonal represents the hypotenuse

Mathematically;

sin 30 = b/20

From triangle ABC

b = 20 sin 30 = 20 * 0.5 = 10 cm

Now, to get l

Mathematically;

Sin 60 = l/20

l = 20 sin 60 = 17.32 cm

So the perimeter is;

2(10 + 17.32)

2(27.32) = 54.64 cm which is 54.6 to the nearest tenth

A price floor is a law that limits the minimum price at which a good, service, or factor of production can be sold while a price ceiling is a regulation that limits the maximum price at which a good, service, or factor of production can be sold

Price floors are commonly implemented to support producers, while price ceilings are typically put in place to protect consumers from higher prices that might result from shortages or monopolies.

Example of Price Floor:Agricultural subsidies are a common example of price floors. Government price floors ensure that farmers receive a minimum price for their crops.

If the market price of wheat falls below the government-established price floor, the government may buy the excess supply at the guaranteed price, ensuring that farmers are able to make a profit. If there is a price floor, the minimum price is set above the equilibrium price.

Answer:

  C.  142°

Step-by-step explanation:

You want the angle between vectors u=3i+√3j and v=-2i-5j.

There are a number of ways the angle between the vectors can be found. For example, the dot-product relation can give you the cosine of the angle:

  u•v = |u|·|v|·cos(θ) . . . . . . where θ is the angle of interest

You can find the angles of the vectors individually, and subtract those:

  u = |u|∠α

  v = |v|∠β

  θ = α - β

When the vectors are expressed as complex numbers, the angle between them is the angle of their quotient:

  \(\dfrac{\vec{u}}{\vec{v}}=\dfrac{|\vec{u}|\angle\alpha}{|\vec{v}|\angle\beta}=\dfrac{|\vec{u}|}{|\vec{v}|}\angle(\alpha-\beta)=\dfrac{|\vec{u}|}{|\vec{v}|}\angle\theta\)

This method is used in the calculation shown in the first attachment. The angle between u and v is about 142°.

A graphing program can draw the vectors and measure the angle between them. This is shown in the second attachment.

Additional comment

The approach using the quotient of the vectors written as complex numbers is simply computed using a calculator with appropriate complex number functions. There doesn't seem to be any 3D equivalent.

The dot-product relation will work with 3D vectors as well as 2D vectors.

An equivalent double integral with the order of integration reversed can be written as π/⁴∫₀ ¹∫ₜₐₙ ᵧ dy dx.

To understand why this is the correct answer, let's analyze the given integral ¹∫₀ ᵗᵃⁿ⁻¹ˣ∫₀ dy dx and how the order of integration can be reversed.

In the original integral, we have the limits of integration as ᵗₐₙ⁻¹ to ₀ for x and ₀ to ᵧ for y. To reverse the order of integration, we need to switch the order of the integrals and reverse the limits accordingly. Therefore, the equivalent double integral with the order of integration reversed becomes ∫₀ ᵧ ¹∫ₜₐₙ ᵡ dx dy.

Now, let's analyze the options given. Option A has the limits of integration for the inner integral as ₀ to ᵧ and the outer integral as π/⁴ to ₀, which matches our reversed order of integration. Therefore, the correct answer is A) π/⁴∫₀ ¹∫ₜₐₙ ᵧ dy dx.
