Answer:

141 square inches

Step-by-step explanation:

Area of a triangle: Base*Height*1/2

Area of a trapezoid: Height * (Base1 +Base2) / 2

Triangle Base = 6

Triangle Height = 8

6*8*1/2 = 24 square inches

Trapezoid Height = 9

Trapezoid Base1 = 16

Trapezoid Base2 = 10

9*(16+10) / 2 = 117 square inches

Total = Area of triangle + Area of trapezoid

Total = 24 + 117 = 141 square inches

The problem deals with finding the wave function and its properties of a superposition of two matter waves of equal amplitude, traveling in opposite directions.

We are required to find the probability density function, positions of the nodes of the standing wave, and the most probable locations of the particle. (a) The probability density function is given by |Ψ(x,t)|^2=4|ψ0|^2cos^2(kx-ωt). Since A=B=ψ0, we can simplify it as |Ψ(x,t)|^2=4|ψ0|^2cos^2(kx-ωt) (b) The positions of the nodes are the positions where the probability density function is equal to zero. In this case, the probability density function is zero whenever cos^2(kx-ωt)=0. This occurs when kx-ωt=nπ/2, where n is an integer. Solving for x, we get x=(nλ/2)+(λ/4). (c) The most probable location of the particle is where the probability density function is maximum. The maximum value of the probability density function is 4|ψ0|^2. Thus, the most probable location is where cos^2(kx-ωt)=1, which occurs when kx-ωt=nπ, where n is an integer. Solving for x, we get x=nλ/2.

Answer: whats the equation

Step-by-step explanation:

When a mountain is cut off at 4,000 feet, a cone is created that has a radius that is half that of the original mountain.

This is because the radius and height of cones both change in an inverse manner as height increases. As a result, volume changes as the inverse cube of rising height (represented as a proportion of the cone's overall height):

The volume of the cone above water is \(1/8$\) the total volume of the cone (mountain). Since these cones are obviously comparable, the little cone's radius and height must equal

The sum of unit vectors for M(- 3/4, 5, 2/3) and N(6, - 9, ⅗) is (27/4√(8329/900))i - (14/√(8329/900))j - (1/15√(8329/900))k.

To write MN as the sum of unit vectors, we first need to find the vector MN, which is the difference between the position vectors of M and N. Then, we divide this vector by its magnitude to obtain a unit vector in the same direction. Finally, we express MN as the sum of these unit vectors.

MN = N - M = (6 - (-3/4), -9 - 5, 3/5 - 2/3) = (27/4, -14, -1/15)

|MN| = √((27/4)² + (-14)² + (-1/15)²) = √(8329/900)

Unit vector in the direction of MN = MN/|MN| = (27/4√(8329/900), -14/√(8329/900), -1/15√(8329/900))

Therefore, MN can be written as the sum of unit vectors:

Answer:

  x = 14°

  y = 5°

Step-by-step explanation:

Angle COL is complementary to both 25° (∠AOC) and 5y (∠LOM). Then it must be true that ...

  5y = 25°

  y = 5° . . . . . . divide by 5

__

Similarly, angle MOB is complementary to angle LOM, so ...

  90° -25° = 3x +23°

  42° = 3x . . . . . subtract 23° and simplify

  14° = x . . . . . .  divide by 3

The values of x and y are ...

Answer:

between 10 and 12

Step-by-step explanation:

Given the measure of angles:

m∠B = 70°

m∠C = 60°

m∠A = 50°

Following this information, since the side lengths are directly proportional to the angle measure they see:

Angle B is the largest angle. Therefore, side AC is the longest side of the triangle since it is opposite of the largest angle.

Angle C is the smallest angle, so the side AB is the shortest side.

Therefore, side BC must be between 10 and 12 inches.

The probability that at least one out of three bulbs lasts 1000 hours or more is 0.973 or approximately 97.3%.

To solve this problem, we need to use the concept of complementary probability. Complementary probability states that the probability of an event occurring plus the probability of its complement (the event not occurring) equals 1. Therefore, we can find the probability of at least one bulb lasting 1000 hours or more by finding the complement of the probability that all three bulbs fail before 1000 hours.

The probability that a single bulb fails before 1000 hours is 0.3. Therefore, the probability that it lasts 1000 hours or more is 0.7. Using this probability, we can find the probability that all three bulbs fail before 1000 hours as follows:

Probability of all three bulbs failing = 0.3 x 0.3 x 0.3 = 0.027

This means that the probability of at least one bulb lasting 1000 hours or more is the complement of 0.027, which is:

Probability of at least one bulb lasting 1000 hours or more = 1 - 0.027 = 0.973 or 97.3%

The radius of the circle will be 4.6m.

What is area of a circle?

The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value. The area of the circle will be A = \(\pi r^{2}\).

The area of the circle given is = 15 m²

Heterogeneous fractions are fractions that have different denominators.

To add heterogeneous fractions, we must first find the common denominator. This is the least common multiple (LCM) of the denominators.

Then, we must multiply the common denominator by the original denominator and multiply by the numerator.

Then, we write as numerators the results obtained previously with the sign of the sum between them.

Finally, we add the numerators and simplify the result if possible.

Answer:

19/24

Step-by-step explanation:

(1/8) + (4/6)

To add fractions, the denominators must be equal. To achieve this, we can multiply the numerator and denominator by a number for each fraction for each fraction's denominator to match.

1/8 = 1/8 * 3/3 = 3/24

4/6 = 4/6 * 4/4 = 16/24

1)Winston grows green dragon apples. This year, he shipped 80%of these apples to sell at supermarkets and kept the rest to make cider. Of all the green dragon apples he sold to the supermarkets, only 60% of them were bought. If a total of 420 green dragon apples were bought, how many green dragon apples did Winston keep to make cider?

 Call the number he shipped to the store, N

So .

60N  = 420   divide both sides by  ,60

420 / .60  = N  = 700 were shipped to the stores

But this number was  80%  of the total he grew = T

So

.80T  = 700   divide both sides by  .80

700/.80 = T  = 875

But..he kept 20% of these =   875 * .20  = 175

2)Ms. Forsythe gave the same algebra test to her three classes. The first class averaged 80%, the second class averaged 85%, and the third 89%. Together, the first two classes averaged 83%, and the second and third classes together averaged 87%. What was the average for all three classes combined? Express your answer to the nearest hundredth.

The average  =  total points / number of students

So....total points = average*number of students

Let the total number of students in  each class = x , y  and z

The total number of points the first class amassed  was   80x

The total number of points amased by the second class was  85y

The total number of points amassed by the third class = 89z

So...for the first two classes we have

[ 80x + 85y ] / [ x + y] = 83

80x + 85y = 83x + 83y  subtract  80x, 83y from both sides    

3x = 2y

x = 2/3y

And,,,for the second two classes we have

[ 85y + 89z ]  / [ y + z ]  =  87  

[  85y + 89z ]  = 87 [y + z]

85y + 89z = 87y + 87z      subtract  85y, 87z from both sides

2z = 2y  

y  = z

So...for the three classes.....

Total points by all three classes /  number of class members  = the average for all three classes

[ 80x + 85y  + 89z ] /  [ x + y + z ]   =

[sub for  x and z ]  

[80 (2/3)y  + 85y  + 89y]  /  [ (2/3)y  + y  + y ]  

y [ 80 (2/3)  + 85  + 89 ]  / [  y [( 2/3) + 1 + 1] ]       [cancel the y's ]

[ 80 (2/3) + 85 + 89]  [  8/3 ]

[ 160/3 + 85 + 89 ] /  [8/3] =

[ 160/3  + 255/3 + 267/3]  / [8/3]     multiply  top/bottom by 3

[160 + 255 + 267 ] / 8  =

The given equation 6x+2y=13 is a linear equation in two variables. In this equation, x and y are variables while 6 and 2 are their respective coefficients, and 13 is a constant term. The equation can be represented as a straight line on a graph. The slope of this line is -3, and it intersects the y-axis at the point (0, 13/2).

In this equation, if we substitute x=0, then y=13/2, and if we substitute y=0, then x=13/6. These are the two points that the line passes through the x and y-axis.

A linear equation is a polynomial equation that is of the first degree, meaning the variables in the equation are not raised to any powers other than one. This equation is in the standard form where the variables are in the first degree. 6x + 2y = 13 is the form of the given linear equation. x and y are the two variables, and 6 and 2 are their respective coefficients. The equation can be represented as a straight line on a graph. The slope-intercept form of this equation is y = -3x + 13/2. The equation is also in standard form.

When x = 0, the equation becomes 2y = 13. This means that the point of intersection is (0, 13/2) when y = 0, the equation becomes 6x = 13, and the point of intersection is (13/6, 0). The slope of the line is -3. When x increases by 1, y decreases by 3.
