Solve seven tenths times two fourths?
two fortieths
five fortieths
seven fortieths
fourteen fortieths

Answer:

83 degrees

Step-by-step explanation:

We can use the consecutive angle theorem to find the the value of x.

We can do that by doing 5x+10.5+6x+10 = 180

After simplifying, we get 11x+20.5=180

Subtract 20.5 on both sides and you get 11x=159.5.

Divide by 11 on both sides and you get x=14.5

Now we can use opposite angle theorem and set angle N and angle T equal.

That means we could write 5x+10.5 = m<T

We can substitute 14.5 for x and we get 72.5+10.5 = m<T

Simplify and you get 83 = m<T

The amount of tile needed to cover the pedestal will depend on the size and shape of the pedestal. In order to determine how much tile is needed, you will need to measure the surface area of the pedestal.

The pedestal's dimensions are height, breadth, and length.

Multiply the height, width, and length of the pedestal to calculate the surface area.

Multiply the surface area by the number of tiles needed to cover the pedestal. To determine the number of tiles needed, divide the surface area by the area of each tile.

For example, if the pedestal is 2 feet tall, 2 feet wide, and 4 feet long, the surface area is 16 square feet. If each tile has an area of 1 square foot, then it will take 16 tiles to cover the pedestal.

In conclusion, the amount of tile needed to cover the pedestal will depend on the size and shape of the pedestal and the size of the tiles. To determine the amount of tile needed, measure the surface area of the pedestal and then multiply it by the number of tiles needed to cover the pedestal.

The pedestal's size and shape will determine how much tile is required to cover it. It will take 1176cm² of tiles to cover the pedestal.

You will need to measure the pedestal's surface area in order to figure out how many tiles you need. The height, width, and length of the pedestal are the same. To determine the surface area, multiply the pedestal's height, width, and length.

S = 2*s1 + s2 + 2*s3

= 96 + 480 + 600

= 1176

Divide the total number of tiles required to cover the pedestal by the surface area. Divide the surface area by the area of each tile to determine the required number of tiles.

The surface area, for instance, is 16 square feet if the pedestal is 2 feet tall, 2 feet wide, and 4 feet long. 16 tiles will be required to cover the pedestal if each tile has a surface area of one square foot.

In conclusion, the dimensions of the tiles and the pedestal's size will determine how much tile is required to cover the pedestal. Multiply the surface area of the pedestal by the number of tiles required to cover it to find the required quantity of tiles.

The given mathematical expression is evaluated for the input values (2, 4). The result of the expression is calculated using various operations such as addition, multiplication, square root, natural logarithm, minimum, maximum, and function composition.

The expression f(x1, x2) involves several mathematical operations. Let's evaluate each part of the expression step by step:

1. The first term is 421 + 222, which equals 643.

2. The second term is 3x² + 213. Plugging in x1 = 2 and x2 = 4, we get 3(2)² + 213 = 3(4) + 213 = 12 + 213 = 225.

3. The third term is 5x11². Substituting x1 = 2 and x2 = 4, we have 5(2)(11)² = 5(2)(121) = 1210.

4. The fourth term is (√₁+√₂)². Replacing x1 = 2 and x2 = 4, we obtain (√2 + √4)² = (1 + 2)² = 3² = 9.

5. The fifth term is 10ln(₁). Plugging in x1 = 2, we have 10ln(2) = 10 * 0.69314718 ≈ 6.9314718.

6. The sixth term is (x₁+x₂)(x² + x3). Substituting x1 = 2 and x2 = 4, we get (2 + 4)(2² + 4³) = 6(4 + 64) = 6(68) = 408.

7. The seventh term is min(3r1, 10√2). As we don't have the value of r1, we cannot determine the minimum between 3r1 and 10√2.

8. The eighth term is max{5x1,2r2}. Since we don't know the value of r2, we cannot find the maximum between 5x1 and 2r2.

9. Finally, we have MP1(x1, x2), MP2(X1, X2), and TRS(x1, x2), which are not defined or given.

Considering the given expression, the evaluated terms for the input values (2, 4) are as follows:

- 421 + 222 = 643

- 3x² + 213 = 225

- 5x11² = 1210

- (√₁+√₂)² = 9

- 10ln(₁) ≈ 6.9314718

- (x₁+x₂)(x² + x3) = 408

The terms involving min() and max() cannot be calculated without knowing the values of r1 and r2, respectively. Additionally, MP1(x1, x2), MP2(X1, X2), and TRS(x1, x2) are not defined.

The probability density in position space for the state |(x, 0)⟩ in the infinite well is a sinc function with two peaks. The probability density can be greater than 1 because the state |(x, 0)⟩ is a superposition of two eigenstates of the Hamiltonian, and the probability density for a superposition of eigenstates can be greater than 1.

The probability density in position space for the state |(x, 0)⟩ is given by:

p(x) = |⟨x|(x, 0)⟩|^2 = |sin(x) + i sin(2x)|^2

This is a sinc function with two peaks, one at x = 0 and one at x = 0.5. The probability density can be greater than 1 because the state |(x, 0)⟩ is a superposition of two eigenstates of the Hamiltonian, |sin(x)⟩ and |sin(2x)⟩. The probability density for a superposition of eigenstates can be greater than 1 because the probability density for an eigenstate is 1, and the probability density for a superposition of eigenstates is the sum of the probability densities for the individual eigenstates.

The state |(x, 0)⟩ can be written as a superposition of the eigenstates of the Hamiltonian as follows:

|(x, 0)⟩ = |sin(x)⟩ + |sin(2x)⟩

The probability density for the state |(x, 0)⟩ is then the sum of the probability densities for the individual eigenstates:

p(x) = |⟨x|sin(x)⟩|^2 + |⟨x|sin(2x)⟩|^2

The probability density for |sin(x)⟩ is 1, and the probability density for |sin(2x)⟩ is 0.5, so the probability density for |(x, 0)⟩ is 1 + 0.5 = 1.5.

b)

The state |(x, t)⟩ at time t is given by:

|(x, t)⟩ = e^(-iHt/ℏ)|(x, 0)⟩

where H is the Hamiltonian of the system.

c)

The expectation value of the position operator at time t is given by:

⟨x(t)⟩ = ⟨(x, t)|x|(x, t)⟩

d)

The expectation value of the momentum operator at time t is given by:

⟨p(t)⟩ = ⟨(x, t)|p|(x, t)⟩

Ehrenfest's theorem states that the expectation values of the position and momentum operators obey the equations of motion for a classical particle. In this case, the equations of motion for a classical particle are:

dx/dt = p

dp/dt = -V'(x)

where V(x) is the potential energy of the particle.

The expectation values of the position and momentum operators satisfy these equations of motion. This is because the expectation values of the position and momentum operators are the average values of the position and momentum of the particle, and the average values of the position and momentum of the particle obey the equations of motion for a classical particle.

a and b must be chosen in such a way that the resulting function f(x) has real coefficients.

From the given graph, it can be observed that the zero is located at x = 2, and the other two roots are non-real and conjugate pairs.

Let these two roots be represented by a + bi and a - bi, respectively.

The function can be expressed in factored form as follows:

f(x) = k (x - 2) (x - (a + bi)) (x - (a - bi))

Where k is a constant.

Since the leading coefficient of the polynomial is not given, let us assume k = 1 for simplicity.

Thus:

f(x) = (x - 2) (x - (a + bi)) (x - (a - bi))f(x)

= (x - 2) ((x - a) - bi) ((x - a) + bi)

Now, we simplify the expression:

f(x) = (x - 2) ((x - a)² - b²i²)f(x)

= (x - 2) ((x - a)² + b²)f(x)

= (x - 2) (x² - 2ax + a² + b²)

Now, we expand the product:f(x) = x³ - 2ax² + (a² + b² - 2) x + 2a² - 2ab²

The required third-degree polynomial function f(x), with real coefficients sketched here given that 2i is a zero, is:

x³ - 2ax² + (a² + b² - 2) x + 2a² - 2ab² = 0

We have shown that two non-real roots of the polynomial are a + bi and a - bi, which are complex conjugates.

Therefore, a and b must be chosen in such a way that the resulting function f(x) has real coefficients.

Let's use "w" to represent the width of the rectangle and "l" to represent the length.

According to the problem statement, the area of the rectangle is numerically equal to its perimeter, so we can write:

2(l + w) = lw

Simplifying this equation, we get:

2l + 2w = lw

Dividing both sides by 2, we get:

l + w = 0.5lw

Multiplying both sides by 2, we get:

2l + 2w = lw

Since the length of the rectangle is 5 times its width, we can write:

l = 5w

Substituting this into the previous equation, we get:

2(5w) + 2w = 5w^2

Simplifying this equation, we get:

10w + 2w = 5w^2

12w = 5w^2

Dividing both sides by w, we get:

12 = 5w

So the width of the rectangle is:

w = 12/5 = 2.4 cm

And the length of the rectangle is:

l = 5w = 12 cm

Therefore, the width of the rectangle is 2.4 cm and the length of the rectangle is 12 cm.

Answer:

Width: 2.4 cm

Length: 12 cm

Step-by-step explanation:

Let the width of the rectangle be w cm, and the length be 5w cm. The area A and perimeter P of the rectangle can be expressed as follows:

Area (A) = length × width

A = 5w × w = 5w^2 cm^2

Perimeter (P) = 2 × (length + width)

P = 2 × (5w + w) = 2 × 6w = 12w cm

According to the problem, the area is numerically equal to the perimeter:

A = P

5w^2 = 12w

To solve for w, we can rearrange the equation:

5w^2 - 12w = 0

w(5w - 12) = 0

This equation has two possible solutions:

w = 0

In this case, the width would be 0 cm, which doesn't form a valid rectangle.

5w - 12 = 0

5w = 12

w = 12/5 = 2.4 cm

For the second solution, the width is 2.4 cm. Now, we can calculate the length:

length = 5w

length = 5 × 2.4 = 12 cm

So, the width of the rectangle is 2.4 cm, and the length is 12 cm.

Step-by-step explanation:

The sequence aₙ = 8n / (4n + 1) is convergent, and its limit is 2.

To determine whether the sequence aₙ = 8n / (4n + 1) is convergent, we can examine its limit as n approaches infinity. Divide both the numerator and the denominator by the highest power of n, in this case, n:

aₙ = (8n / n) / ((4n / n) + (1 / n))

aₙ = (8 / 4 + 1 / n)

As n approaches infinity, 1/n approaches 0. Thus, we have:

aₙ = 8 / 4

aₙ = 2

Answer:

the total weight of the hosepipe and the reel is 7.4 kg

Step-by-step explanation:

First, we need to find the weight of the hosepipe, we know that 1/2 metre of the hosepipe has a weight of 150 grams, therefore we can conclude that 1 meter has a weight of (150)(2) = 300 grams.

If one meter weighs 300 grams, then 20 meters have a weight of \(20(300) = 6000\) grams. But since 1000 grams are 1 kg, this would be equivalent to 6 kg.

Now, to find the total weight of the hosepipe and the reel we are going to sum up the 2 weights:

Total weight = hose pipe weight + reel weight

Total weight = 6 kg + 1.4 kg

Total weight = 7.4 kg.

Therefore, the total weight of the hosepipe and the reel is 7.4 kg

If rent for 3 days of fogging machine is $38, then it will cost $174 for renting it for 9 days.

Let the total cost of renting the fog machine for 9 days be = x;

We know that, the rental cost is $38 for every 3 days.

So, for 9 days, we need to rent the fog machine for three 3-day periods.

This can be written as:

⇒ Rental cost = 3 × ($38) = $114

The delivery cost is a one-time fee of $60.

So, the equation for the total cost can be written as,

⇒ x = Rental cost + Delivery cost

⇒ x = $114 + $60

⇒ x = $174

Therefore, the cost of renting the fog machine for 9 days is $174.
