The general solution of the system is given by:

x(t) = c1 [x1, -√3x1/2] e^(4 + √12)t + c2 [x1, √3x1/2] e^(4 - √12)t

To find the general solution of the given system, we first need to find the eigenvalues and eigenvectors of the coefficient matrix.

The characteristic equation is given by:

|10 - λ -20|

| 8 -18 - λ| = (10 - λ)(-18 - λ) - (-20)(8) = λ^2 - 8λ + 4 = 0

The roots of this equation are λ = 4 ± √12.

For λ = 4 + √12, the corresponding eigenvector is found by solving the equation:

|10 - (4 + √12) -20| |x1| |0|

| 8 -18 - (4 + √12)| |x2| = |0|

This leads to the equation 4x1 + √12 x2 = 0, which can be simplified to x2 = -√3 x1/2. Thus, the eigenvector is [x1, -√3x1/2].

For λ = 4 - √12, the corresponding eigenvector is found by solving the equation:

|10 - (4 - √12) -20| |x1| |0|

| 8 -18 - (4 - √12)| |x2| = |0|

This leads to the equation 4x1 - √12 x2 = 0, which can be simplified to x2 = √3 x1/2. Thus, the eigenvector is [x1, √3x1/2].

Therefore, the general solution of the system is given by:

x(t) = c1 [x1, -√3x1/2] e^(4 + √12)t + c2 [x1, √3x1/2] e^(4 - √12)t

where c1 and c2 are constants determined by the initial conditions.

The surface will be a hyperboloid of two sheets, since it has one positive and two negative squared terms. The xz- and yz-planes will contain hyperbolas, while the xy-plane will contain an ellipse.

To sketch the surface given by the equation −x² + 7y² − z² = 7, we can start by analyzing its traces in the x-, y-, and z-planes:

1. x-trace: Set x = 0 in the equation:
7y² - z² = 7
Divide by 7:
y² - (z²/7) = 1
This is a hyperbola in the yz-plane.

2. y-trace: Set y = 0 in the equation:
-x² - z² = 7
Divide by -1:
x² + z² = -7
Since x² and z² are always non-negative, there is no y-trace.

3. z-trace: Set z = 0 in the equation:
-x² + 7y² = 7
Divide by 7:
-(x²/7) + y² = 1
This is an ellipse in the xy-plane.

Now that we have the traces, we can sketch the surface by visualizing how these traces intersect and extend in 3D space.

We need to find the relationships between the constants b1, b2, b3, b4, and b5.

Step 1: Identify the linear system
The system given is:
x1 - 4x2 = b1
x1 - 3x2 = b2
x1 + x2 = b3
x1 - 5x2 = b4
x1 + 6x2 = b5

We will start by subtracting the second equation from the first equation:
(b1 - b2) = x2

Now, subtract the first equation from the fourth equation:
(b4 - b1) = -x2

Step 3: Solve for the relationships between the constants
Add the equations we found in step 2:
(b1 - b2) + (b4 - b1) = x2 - x2

Simplify the equation:
b4 - b2 = 0

So, we have found one relationship between the constants:

Step-by-step explanation:

Let's break down the expression 17(4 + 15) to better understand the problem:

17(4 + 15) = 17(19)

= 323

So the expression simplifies to 323.

Student A evaluated the expression by adding the product of 17 and 4 to the product of 17 and 15.

So, Student A's evaluation is incorrect because they did not distribute the 17 to each term inside the parentheses. The correct process would be:

17(4 + 15) = 17*4 + 17*15

= 68 + 255

= 323

Student B evaluated the expression by determining the product of 17 and 19.

So, Student B's evaluation is correct because 17 times 19 gives us 323, which is the solution to the expression 17(4+15).

Therefore, Student A's evaluation is incorrect, while Student B's evaluation is correct.

The proportion of rent that the friend with the smaller bedroom has to pay is 125/265. So his share of the rent is $540.35.

Suppose the distance from your house to your school is 2 miles, while the distance from your house to the nearest park is 3 miles.

Then we say that the ratio of the two distances s 2:3. To take another example suppose in today's hw, you have got 10 questions to answer, while in yesterday's hw you had 7 questions to answer. In this case we say that the ratio of the no of hw questions you have today, to the no questions you had yesterday is 10:7.

A ratio is a pair of numbers which gives the relative magnitudes of two similar quantities. A ratio of a:b is also represented by the fraction a/b.

Let us use the previous example. the ratio of the distances from your home to your school and to the nearest park is say 2:3 . Now consider the ratio of the time it takes to reach your school from your home by car to the time it takes to reach the park by car from your home. suppose this ratio a:b . Then it reasonable to assume that the two fractions a/b and 2/3 are equal, assuming the car moves at the same average speed.

This common ratio is called the proportion. we write it as follows,dist to school : dist to park : : time to school : time to park.

This is read as the distance to school IS TO distance to park AS time to school IS TO time to park.

if we write the ratios as fractions. Then they are proportional or equivalently they are the same proportion if and only if the two fractions are equal.

So The ratio of the bedroom sizes is 125 : 140.

Total rent that is to be divided between them is $1150.

if the share of the rents are a,b. then as fractions a/b = 125/140

So. a/a+b = 125/125+140 = 125/265

but a + b = 1150

So a = 125/265 (1150) = 542.452

The point on the plane 4x + 7y + 8z - 14 = 0 closest to the point (-2,2,3) is (-1, 1, 1). This can be answered by the concept of Distance formula.

To find the point on the plane closest to the given point, we can use the formula for the distance between a point and a plane. The formula states that the distance between a point (x1, y1, z1) and a plane Ax + By + Cz + D = 0 is given by:

Distance = |Ax1 + By1 + Cz1 + D| / √(A² + B² + C²)

In this case, the coefficients of x, y, and z in the equation of the plane are A = 4, B = 7, and C = 8, and D = -14. The given point is (-2, 2, 3), so x1 = -2, y1 = 2, and z1 = 3.

Plugging these values into the formula, we get:

Distance = |4(-2) + 7(2) + 8(3) - 14| / √(4² + 7² + 8²)

Simplifying, we get:

Distance = 35 / √(189)

To find the point on the plane closest to the given point, we need to minimize this distance. Since the distance is a positive value, the point on the plane closest to the given point will be the one that minimizes the numerator of the distance formula, which is |4(-2) + 7(2) + 8(3) - 14|. This occurs when the numerator is equal to zero.

Setting the numerator equal to zero, we get:

4(-2) + 7(2) + 8(3) - 14 = 0

Solving for x, y, and z, we get:

x = -1

y = 1

z = 1

Therefore, the point on the plane closest to the given point (-2, 2, 3) is (-1, 1, 1).

The dimensions of the closed cylinder that maximize its volume are radius=25 cm and height=40 cm. The maximum volume is 62,500 cubic cm.

Given that the total surface area of the closed cylinder is 5000 cm^2, we can write the equation for the total surface area as:

2πrh + 2πr^2 = 5000

We want to find the dimensions that maximize the volume of the cylinder. The volume of a cylinder is given by:

V = πr^2h

We can use the equation for the total surface area to solve for h in terms of r:

h = (5000 - 2πr^2) / (2πr)

Substituting this expression for h into the equation for the volume, we get:

V = πr^2[(5000 - 2πr^2) / (2πr)]

Simplifying this expression, we get:

V = (2500πr - πr^3)

To find the maximum volume, we take the derivative of V with respect to r and set it equal to zero:

dV/dr = 2500π - 3πr^2 = 0

Solving for r, we get r=25 cm.

We can then substitute this value of r into the expression for h to get h=40 cm.

Therefore, the dimensions of the cylinder that maximize its volume are radius=25 cm and height=40 cm.

Substituting these values into the equation for the volume, we get:

V = π(25)^2(40) = 62,500 cubic cm.

To verify that this is a maximum point, we can take the second derivative of V with respect to r:

d^2V/dr^2 = -6πr

At r=25 cm, this is negative, which indicates that we have a maximum point. Therefore, the dimensions calculated above do indeed maximize the volume of the cylinder.

the wavelength of the electron is approximately 122 nm To find the wavelength of an electron, we can use the de Broglie wavelength formula:

wavelength (λ) = h / (m * v)

where:
- h is Planck's constant (6.63 x 10^-34 Js)
- m is the mass of the electron (9.11 x 10^-28 g, which needs to be converted to kg)
- v is the speed of the electron (5.97 mm/s, which needs to be converted to m/s)

Step 1: Convert the mass of the electron to kg:
9.11 x 10^-28 g * (1 kg / 1000 g) = 9.11 x 10^-31 kg

Step 2: Convert the speed of the electron to m/s:
5.97 mm/s * (1 m / 1000 mm) = 5.97 x 10^-3 m/s

Step 3: Plug the values into the de Broglie wavelength formula:
λ = (6.63 x 10^-34 Js) / (9.11 x 10^-31 kg * 5.97 x 10^-3 m/s)

Step 4: Calculate the wavelength:
λ = (6.63 x 10^-34 Js) / (5.44 x 10^-33 kg m/s) ≈ 1.22 x 10^-10 m

Step 5: Convert the wavelength to nm:

Answer:

1 hour 45 minutes.

Step-by-step explanation:

We can count up to determine the length of time.

from 1725 to 1800 is 35 minutes.  (Remember that time is in increments of 60 minutes).  Add another hour to 1900.  Add 10 minutes to 1910

We have a total of 35 minutes plus 1 hour plus 10 minutes

1 hour 45 minutes.
