The value of x from the triangle is x = 31

What are similar triangles?

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be ABC

The measure of side AB = 14.5

The measure of side BC = 15.5

Let the second triangle be XYZ

The measure of side XY = 29

The measure of side YZ = x

Now , if the triangle ABC is similar to triangle XYZ , then the corresponding sides of the triangles will be equal in ratio

So , the equation will be

XY / AB = YZ / BC

Substituting the values in the equation , we get

29 / 14.5 = x / 15.5

On simplifying the equation , we get

x/15.5 = 2

Multiply by 15.5 on both sides of the equation , we get

x = 2 x 15.5

x = 31

Therefore , the value of x is 31

Hence , the value of x of side YZ is 31

Answers

For the given equation the value of n is equal to option D.

n = (s/180) + 2.

As given in the question,

Given equation is equal to  :

s = (n-2)180

Now take all the terms on one side and term n on other side of the equation we have,

Divide both the side by 180 we get,

Consider a particle in a rigid box of length L. For each of the states n = 1, n = 2 and n = 3:
a. Sketch graphs of ǀ (x) ǀ2. Label the points x = 0 and x = L.
b. Where, in terms of L, are the positions at which the particle is most likely to be found?
c. Where, in terms of L, are the positions at which the particle is least likely to be found?
d. Determine, by examining your ǀ (x) ǀ2 graphs, if the probability of finding the particle in the left one-third of the box is less than, equal to, or greater than 1 3. Explain your reasoning.
e. Calculate the probability that the particle will be found in the left one-third of the box.

Answers

For states, n = 1, 2, and 3 the probability of finding the particle at left 1/3rd of the box is P₁ = (3/4) * (2/L)²    P₂ = (1/4) * (2/L)²    and    P₃ = (1/3) * (2/L)²  respectively

a.

The wave function for the particle in a rigid box of length L for the state

n = 1, is given by:

|ψ₁(x)|² = (2/L)² * sin²(πx/L)

the wave function for the state n = 2,  is given by:

|ψ₂(x)|² = (2/L)² * sin²(2πx/L)

And the wave function for the state n = 3, is given by:

|ψ₃(x)|² = (2/L)² * sin²(3πx/L)

The graphs of |ψ₁(x)|², |ψ₂(x)|², and |ψ₃(x)|² is attached.

b.

The points of maximum probability density, which occur at x = 0 and       x = L for all three states are the positions at which the particle is most likely to be found.

c.

The points of minimum probability density, occur at x = L/2 for the state

n = 1, and at x = L/4 and x = 3L/4 for the state n = 2. For the state n = 3, the points of minimum probability density occur at x = L/3, x = 2L/3, and

x = L are the positions at which the particle is least likely to be found.

d.

Since the probability density is highest at x = 0, which is in the left one-third of the box for the state n = 1 the probability of finding the particle in the left one-third of the box is greater than 1/3.

Since the probability density is highest at x = 0 and x = L, which are both outside the left one-third of the box for the state n = 2, the probability of finding the particle in the left one-third of the box is less than 1/3.

Since the probability density is highest at x = 0, which is in the left one-third of the box for the state n = 3, the probability of finding the particle in the left one-third of the box is equal to 1/3.

e.

We need to integrate the probability density over the region of interest to calculate the probability that the particle will be found in the left one-third of the box for each of the states n = 1, n = 2, and n = 3.

the probability for the state n = 1,  is given by:

P₁ = ∫ |ψ₁(x)|² dx = (2/L)² * ∫ sin²(πx/L) dx

The probability for the state n = 2,  is given by:

P₂ = ∫ |ψ_2(x)|² dx = (2/L)² * ∫ sin²(2πx/L) dx

The probability for the state n = 3,  is given by:

P₃ = ∫ |ψ₃(x)|² dx = (2/L)² * ∫sin²(3πx/L) dx

Here all integrals have limits 0 and L/3

Solving these integrals gives:

P₁ = (3/4) * (2/L)²

P₂ = (1/4) * (2/L)²

P₃ = (1/3) * (2/L)²

Thus, the probabilities that the particle will be found in the left one-third of the box are:

P₁ = (3/4) * (2/L)²

P₂ = (1/4) * (2/L)²

P₃ = (1/3) * (2/L)²

for the states n = 1, n = 2, and n = 3, respectively.

Answers

Answer:

The exact value of x so that the greatest possible amount of light is emitted is 8.96ft.

What is the perimeter of a semicircle?

The perimeter of a semicircle is half that of a circle, that is [tex]\pi r[/tex], where r is the radius of the circle.

Step-by-step explanation:

Given the width of the rectangle is x, let the height of the rectangle be y.

The radius of the semicircle is x/2.

The perimeter of the window is equal to [tex]2y+x+\pi \frac{x}{2} =32[/tex].

The area of the window is [tex]xy+\frac{1}{2}(\pi )(\frac{x}{2})^2=xy+\frac{\pi x^2}{8}[/tex].

We can insert into the formula for the area to obtain the area in terms of only x by solving the equation for the perimeter of y in terms of x.

[tex]2y=32-(1+\frac{\pi }{2} )x=32-(\frac{2+\pi }{2} )x\\y=16-(\frac{2+\pi }{4} )x[/tex].

Now the area of the window in terms of only x is:

Area=[tex]16x-(\frac{2+\pi }{4} )x^2+\frac{\pi x^2}{8}[/tex].

Since it is given in the question that maximum light should be admiitted, we will differentiate the Area and set it to 0.

[tex]16-2(\frac{2+\pi }{4} )x+\frac{\pi x}{4}=0\\ 16=x(1+\frac{\pi }{4})\\ x=\frac{16}{1+\frac{\pi }{4}} \\x=8.96ft[/tex].

Therefore the exact value of x is 8.96ft.

Thus, by SAS property both the triangles BAD and CAD are congruent .

By cpct , ∠ADB=∠ADC = x (let)

Since ∠ADB and ∠ADC lies in a straight line

So by the property of straight lines the sum is 180°.

Now  ∠ADB+∠ADC= 180°

Find the distance traveled by a particle with position (x, y) as t varies in the given time interval.
x = 3sin^2(t), y = 3cos^2(t), 0 = t = 5p
Find the length of the curve.

Answers

By The length of the curve can be found using the formula for the arc length of a parametric curve, the distance traveled by the particle is 30π.

The length of the curve can be found using the formula for the arc length of a parametric curve:

L = ∫0→5p √(dx/dt)2 + (dy/dt)2 dt

We can calculate dx/dt and dy/dt as follows:

dx/dt = 6sin(t)cos(t)

dy/dt = -6sin(t)cos(t)

Substituting these values into the formula for the arc length gives us:

L = ∫0→5p √[(6sin(t)cos(t))2 + (-6sin(t)cos(t))2] dt

= ∫0→5p 6√(sin2(t)cos2(t)) dt

= 6∫0→5p |sin(t)cos(t)| dt

= 6∫0→5p sin(t)cos(t) dt

= 6[(1/2)sin2(t) + (1/2)cos2(t)]5p

= 6[(1/2)(1) + (1/2)(1)]5p

= 6(1)5p

= 30π

Therefore, the distance traveled by the particle is 30π.

Step-by-step explanation:

j

Answer:

8 Laps

Step-by-step explanation:

This is because one lap is 1/4 so it would take 4 laps to make it a whole, which would be a mile.

We could now times this by two, since 1 mile is half of 2 miles.

4 x 2 = 8

Which would make it 8

Answers

In this case, the coefficient of determination is 0.5297, which means that 53% of the sample variation in Final grades is explained by the sample regression equation.

The data file contains the midterm and final scores of 32 students in a statistics course. To estimate a student's final score as a function of their midterm score, we used a regression analysis. The regression equation was Final = 27.5818 + 0.6774 Midterm. This equation can be used to predict the final score of a student based on their midterm score. The standard error of the estimate was 14.947. This indicates the accuracy of the estimated final score. The coefficient of determination was 0.5297, which means that 53% of the sample variation in final grades is explained by the regression equation. This tells us that the regression equation is a relatively good predictor of a student's final score.

Given:

Midterm Score = x

Final Score = y

Regression Equation: y = 27.5818 + 0.6774x

Standard Error of the Estimate = 14.947

Coefficient of Determination = 0.5297

Calculating Final Score:

y = 27.5818 + 0.6774x

y = 27.5818 + 0.6774(x)

y = 27.5818 + 0.6774(x)

y = 27.5818 + 0.6774(x)

y = 27.5818 + 0.6774x

Final Score = 27.5818 + 0.6774(Midterm Score)

write an indirect proof in paragraph form. given: triangle rvt and svt are equilateral. triangle rvs is not equilateral

Answers

The indirect proof that defines triangle RVS is not equilateral is explained below.

How triangle look like?

In math, A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices and also a polygon.

Here we need to find the indirect proof for the triangle RVS which is not equilateral.

Here we know that, We need to write an indirect proof in paragraph proof.

For, the given statement, △RVT and SVT are equilateral; 

And △RVS is not equilateral.

Then the explanation for this one is written as,

Let us assume temporarily that △RST is equilateral.

And we have given that △RVT and SVT are equilateral, then the sides of △RVT, SVT, and RST are congruent.

Therefore, RV≅VSRS which follows that △RVS is equilateral.

In contradicts the given that △RVS is not equilateral, then the temporary assumption must be false. It follows that △RST is not equilateral.
