4. Electron

The reason why total energy eigen-functions cannot be written in form x(x)y(y)z(z) c(x, y, z) is that the energy eigenfunctions depend on all three spatial coordinates, x, y, and z, simultaneously.

In other words, the probability density of finding the electron at any point in space is not just a product of separate functions that only depend on one of the coordinates at a time.

Instead, the probability density of finding the electron is determined by the complex wave function, which depends on all three spatial coordinates at the same time.

The wave function gives us information about the energy and the behavior of the electron in the system, and it cannot be factorized into separate functions that depend on only one coordinate at a time.

Therefore, we cannot write the total energy eigenfunction as a product of separate functions of x, y, and z. The total energy eigenfunction is a complex function that depends on all three coordinates simultaneously, and it cannot be separated into individual functions that depend only on one coordinate at a time.

Answer:

Fai's wallet contained $30.

Step-by-step explanation:

$9 = 30%

x = 100%

If you cross multiply:

x * 30% = $9 * 100%

0.3x = $9

x = $9/0.3

x = $30

The gradient of the curve x³ + 3xy²- y³ = 1 at the point with coordinates (1, 3) is -29/9

The gradient of a curve at a point is the value of its derivative at that point.

To find the gradient of the curve x³ + 3xy²- y³ = 1 at the point with coordinates (1, 3). we differentiate implicitly with respect to x.

So, we have that

x³ + 3xy²- y³ = 1

d(x³ + 3xy²- y³)/dx = d1/dx

dx³/dx + d3xy²/dx - dy³/dx = d1/dx

dx³/dx + 3y²dx/dx + 3xdy²/dx - dy³/dx = d1/dx

2x² + 3y² × 1 + 3x × dy²/dy × dy/dx - dy³/dy × dy/dx = d1/dx

2x² + 3y² × 1 + 3x × 2y × dy/dx - 3y² × dy/dx = 0

2x² + 3y² + 6xydy/dx - 3y²dy/dx = 0

6xydy/dx - 3y²dy/dx = -(2x² + 3y²)

Factorizing out dy/dx, we have that

6xydy/dx - 3y²dy/dx = -(2x² + 3y²)

(6xy - 3y²)dy/dx = -(2x² + 3y²)

dy/dx = -(2x² + 3y²)/(6xy - 3y²)

At (1,3) dy/dx =  -(2x² + 3y²)/(6xy - 3y²)

=  -(2(1)² + 3(3)²)/(6(1)(3) - 3(3)²)

=  -(2(1) + 3(9))/(6(1)(3) - 3(9))

=  -(2 + 27)/(18 - 27)

= -29/-9

= 29/9

So, dy/dx = 29/9

Answer: 84

Step-by-step explanation:

Area of whole rectangle = lb = 11x9 = 99

Area of Inner rectangle = lb = 5x3 = 15

Area of Shaded region = Area of whole rectangle - Area of Inner rectangle
                                      = 99 - 15

                                      = 84

Answer:

Area of shaded region = 84 units²

Step-by-step explanation:

Area = Area of bigger - Area of smaller

Yes, that is correct. The expression 0.25t2–4t+28 shows that the value of a first-edition deck of Wandering Wizards will decrease initially when it is first released, then increase as the deck becomes more rare. The maximum value of the deck is 28, which is when t=0 (when the game is first released).

Sure, let's solve this step-by-step:

First, we need to solve for x in the equation x + 1/2 = 5.

We can do this by subtracting 1/2 from both sides, giving us x = 4 1/2.

Now, we can substitute x = 4 1/2 into the equation 2*x^2 - 3x + 6 - 3/x +2/x^2.

We can simplify the equation by multiplying both sides by x^2, giving us:

2*x^2 - 3x + 6 - 3/x +2 = 10*x^2 - 3x + 6.

Now, we can combine all of the terms with x:

10*x^2 - 6x + 6 = 0.

Finally, we can solve the equation using the quadratic formula:

x = 3/5 or x = 2.

Therefore, the answer to the equation is 10*(3/5)^2 - 6(3/5) + 6 = 4.8, or 10*2^2 - 6(2) + 6 = 16.

If you mean something else, you need to identify the quantities that need to be considered as a unit.

The aquarium has six rectangular faces, four of which are identical (two sides and two ends), and two of which are identical to each other but different from the others (top and bottom).

a) We can use the formula for the volume of a rectangular prism, which is given by V = lwh, where l is the length, w is the width, and h is the height. In this case, we have  [tex]V = 12 ft^3 and h = 1.5 ft[/tex] . We want to express y as a function of x, so we need to eliminate w from the equation.

We can rearrange the equation for the volume to get  [tex]w = V/(lh)[/tex] , and substitute in h [tex]= 1.5 ft[/tex] :

[tex]w = V/(1.5lx)[/tex]

Now we can substitute y for w to get:

[tex]y = V/(1.5lx)[/tex]

b)  To find the total surface area, we need to find the area of each face and add them up.

The area of one of the identical sides or ends is lw, so the total area of these four faces is:

[tex]4lw = 4xy[/tex]

The area of the top and bottom faces is lx, so the total area of these two faces is:

[tex]2lx[/tex]

Therefore, the total surface area S is given by:

[tex]S = 4xy + 2lx[/tex]

We can express y in terms of x using the equation from part a):

[tex]y = V/(1.5lx)[/tex]

Substituting this into the expression for S, we get:

[tex]S = 4x(V/(1.5lx)) + 2lx[/tex]

Simplifying, we get:

[tex]S = (8/3)V/x + 2lx[/tex]

So the total surface area S is a function of x, and we can use this equation to find the value of S for any given value of x.

Answer:

Step-by-step explanation:

The given sequence is geometric.

To find the common ratio (r) of the sequence, we need to divide any term by its preceding term. Let's divide the second term (8) by the first term (32):

r = 8/32 = 1/4

Now, we can use the formula for a geometric sequence to find any term:

an = a1 * r^(n-1)

where:

an = nth term of the sequence

a1 = first term of the sequence

r = common ratio

n = position of the term we want to find

Let's use this formula to find the third term:

a3 = 32 * (1/4)^(3-1) = 2

So, the common ratio of the sequence is 1/4, and each term is obtained by multiplying the preceding term by 1/4. The sequence is decreasing rapidly because the ratio is less than 1.

The height of the pole is approximately 17.75 meters.

The main trigonometric functions are sine, cosine, and tangent, which are abbreviated as sin, cos, and tan, respectively. They are used to relate the angles of a right triangle to the lengths of its sides. The sine function gives the ratio of the length of the side opposite an angle to the length of the hypotenuse of the triangle. The cosine function gives the ratio of the length of the adjacent side to the length of the hypotenuse. The tangent function gives the ratio of the length of the opposite side to the length of the adjacent side.

Let's denote the height of the pole as h, and let's denote the distance between the pole and the student's original position (due west of the pole) as x.

From the student's original position, we have a right triangle with the pole being the hypotenuse. The angle opposite to the height of the pole is 40°. So, we have:

tan(40°) = h/x

From the student's new position (10 m due south of the original position), we have another right triangle with the pole being the hypotenuse. The angle opposite to the height of the pole is 35°. The distance between the pole and the student's new position is (x+10) meters (the student moved 10 m south). So, we have:

tan(35°) = h/(x+10)

Now we have two equations with two unknowns (h and x). We can solve for x in terms of h from the first equation:

x = h/tan(40°)

Substitute this expression for x into the second equation:

tan(35°) = h/((h/tan(40°))+10)

Simplify and solve for h:

h = (10 tan(35°) tan(40°)) / (tan(40°) - tan(35°)) ≈ 17.75 m

Therefore, the height of the pole is approximately 17.75 meters.

Answer: To find the distance of a chord from the center of a circle, we need to use the following formula:

Distance from center = sqrt(r^2 - (c/2)^2)

Where r is the radius of the circle and c is the length of the chord.

In this case, the radius of the circle is 3.7cm and the length of the chord is 7cm.

So, substituting these values in the formula, we get:

Distance from center = sqrt(3.7^2 - (7/2)^2)

= sqrt(13.69 - 12.25)

= sqrt(1.44)

= 1.2 cm

Therefore, the distance of the chord from the center of the circle is 1.2 cm.
