Answer 1
ANSWER: A
_________________
EXPLANATION:
{DISCLAIMER: sorry i don’t know where the greater/less than or equal to sign is so imagine it’s there haha)

-8x + 14 (is greater than or equal to)60 OR -4x < 8

conduct problems like these as you would any other problem! :)
on the first side, subtract 14 from both sides so: -8x (is greater than or equal to) 46

divide by -8 on both sides

remember when dividing by a negative with problems involving greater/ less than signs, the sign will flip. so in this case, because we are dividing by a -8, the great than or equal to sign flips around and becomes a less than or equal to sign

so x (is less than or equal to) -46/8
simplify your fraction, and x (is less than or equal to) -23/4
_________________
on the other side: -4x+50 <58

subtract 50 from both sides so: -4x < 8
divide by -4 on both sides so: x > -2

(remember our rule that if we divide by a negative when a sign is present the sign flips)

and there’s your answer!! hope this helps you out:D

Determine the transconductance of a JFET biased at the origin given that gmo = 1.5 mS, VGs = -1 V, and VGscoff) = -3.5 V.

Answers

The transconductance of a JFET biased at the origin is determined.

The transconductance (gm) of a JFET (Junction Field-Effect Transistor) is a crucial parameter that characterizes its ability to convert changes in the gate-source voltage (Vgs) into variations in the drain current (Id). In this case, we are given the following values: gmo (transconductance at the origin) = 1.5 mS, VGs (gate-source voltage) = -1 V, and VGsoff (gate-source voltage at cutoff) = -3.5 V.

To determine the transconductance, we need to consider the relationship between the transconductance at the origin (gmo) and the gate-source voltage (Vgs). The transconductance can be expressed as:

gm = gmo * (1 - Vgs / VGsoff)

Substituting the given values, we have:

gm = 1.5 mS * (1 - (-1 V) / (-3.5 V))

Simplifying the equation:

gm = 1.5 mS * (1 + 1/3.5)

gm = 1.5 mS * (1.286)

gm = 1.929 mS

Therefore, the transconductance of the JFET biased at the origin is approximately 1.929 mS.

how to multiply matrices with different dimensions

Answers

The number of columns in the first matrix must equal the number of rows in the second matrix in order to multiply matrices with different dimensions.

 First, jot down each matrix's dimensions. Let's imagine, for illustration, that we have a matrix A that is 2 by 3 and a matrix B that is 3 by 4. Create a new matrix C with the dimensions 2x4 in step 2. This is what the multiplication will ultimately produce.

    3. Determine the dot product of the corresponding row in matrix A          and the corresponding column in matrix B for each element in matrix C.

    4: The final response is matrix C, which is the union of the 2x3 matrix A and the 3x4 matrix B.

     Therefore, the result is a 2x4 matrix, which is produced by taking the dot product of the rows and columns of matrix A and matrix B.

suppose a worker's completion time is 0.4 standard deviations above the mean. what is the worker's percentile score? round your result to one decimal place.

Answers

The following is how to determine a worker's percentile score if their completion time is 0.4 standard deviations above the mean. To determine a worker's percentile score, we will use the standard normal distribution table.

The formula for converting an X-value into a Z-score is: X - μ / σ = Z Where: X is the observed value of a variable.μ is the mean of the variable.σ is the standard deviation of the variable. Z is the z-score. To calculate the z-score, we'll use the formula: X - μ / σ = 0.4 standard deviations above the mean Z = (X - μ) / σ = 0.4 .The percentile score of the worker is the proportion of the standard normal distribution below this z-score. Using the standard normal distribution table, we can find the proportion that corresponds to the z-score of 0.4. We look for the value in the table that is closest to 0.4 and locate the proportion in the z-score column. For the value of 0.4, we get 0.6554.The percentile score of the worker is 0.6554 or 65.54 percent. We used the standard normal distribution table to calculate a worker's percentile score. The first step was to convert the observed value of a variable to a z-score using the formula: X - μ / σ = Z  .The worker's completion time was 0.4 standard deviations above the mean. This means that the worker's completion time is greater than the mean by 0.4 times the standard deviation. Using the formula above, we can calculate the z-score. The standard deviation for the worker's completion time was not given, so we used the standard deviation of the distribution. We were not given the mean, so we could not calculate the z-score directly. Instead, we calculated the z-score as follows: Z = (X - μ) / σ = 0.4.  We can use this equation to find the worker's completion time if we know the mean and standard deviation. The standard normal distribution table was used to calculate the worker's percentile score. We looked up the value that was closest to 0.4 in the z-score column. The proportion in the table that corresponds to a z-score of 0.4 is 0.6554 or 65.54%.The percentile score of the worker is 65.54%.The worker's percentile score was 65.54%. A percentile score is the proportion of a distribution that is below a certain point. We used the standard normal distribution table to calculate the proportion that corresponds to the worker's z-score of 0.4.

find the general solution of the given higher-order differential equation. d 4y dx4 − 2 d 2y dx2 − 8y = 0

Answers

he required solution is \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

where \(c_1,c_2,c_3\) and \(c_4\) are constants.

Let’s assume the general solution of the given differential equation is,

y=e^{mx}

By taking the derivative of this equation, we get

\(\frac{dy}{dx} = me^{mx}\\\frac{d^2y}{dx^2} = m^2e^{mx}\\\frac{d^3y}{dx^3} = m^3e^{mx}\\\frac{d^4y}{dx^4} = m^4e^{mx}\\\)

Now substitute these values in the given differential equation.

\(\frac{d^4y}{dx^4}-2\frac{d^2y}{dx^2}-8y\\=0m^4e^{mx}-2m^2e^{mx}-8e^{mx}\\=0e^{mx}(m^4-2m^2-8)=0\)

Therefore, \(m^4-2m^2-8=0\)

\((m^2-4)(m^2+2)=0\)

Therefore, the roots are, \(m = ±\sqrt{2} and m=±2\)

By applying the formula for the general solution of a differential equation, we get

General solution is, \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

Hence, the required solution is \(y=c_1e^{2x}+c_2e^{-2x}+c_3\sqrt2\cos(\sqrt2x)+c_4\sqrt2\sin(\sqrt2x)\)

where \(c_1,c_2,c_3\) and \(c_4\) are constants.

Answers

The percentage change in frequency is 0%.Hence, the natural frequency of torsional vibration of the custen is given by f = 25.7 / L₀^(1/2) and the percentage change in frequency is 0%.

We are given that:

Total moment of inertia of moving parts = I = 1 kgm²

Moment of inertia of air-screw = I = 18 kgm²

Outer diameter of hollow shaft = D₀ = 80 mm

Inner diameter of hollow shaft = Dᵢ = 35 mm

Length of hollow shaft = L = 0.30 m

Stiffness of the crank-throw = K = 2.5 × 10⁴ Nm/rad

Shear modulus of elasticity = G = 83000 N/mm²

We need to calculate the natural frequency of torsional vibration of the custen.

The formula for natural frequency of torsional vibration is: f = (1/2π) [(K/L) (J/GD)]^(1/2)

Where, J = Polar moment of inertia

J = (π/32) (D₀⁴ - Dᵢ⁴)

The formula for equivalent length of hollow shaft is given by:

q₁ = q₁₁ + q₁₂

Where, q₁₁ = (π/32) (D₀⁴ - Dᵢ⁴) / L₁q₁₂ = (π/64) (D₀⁴ - Dᵢ⁴) / L₂

L₁ = length of outer diameter

L₂ = length of inner diameter

For the given shaft, L₁ + L₂ = L

Let L₁ = L₀D₀ = D = 80 mm

Dᵢ = d = 35 mm

So, L₂ = L - L₁= 0.3 - L₀...(1)

For the given crank-throw, q₁ = (π/32) (D⁴ - d⁴) / L, where D = 80 mm and d = 80 mm

Hence, q₁ = (π/32) (80⁴ - 35⁴) / L

Therefore, q₁ = (π/32) (80⁴ - 35⁴) / L₀...(2)

From the formula for natural frequency of torsional vibration, f = (1/2π) [(K/L) (J/GD)]^(1/2)

Substituting the values of K, J, G, D and L from above, f = (1/2π) [(2.5 × 10⁴ Nm/rad) / (L₀) ((π/32) (80⁴ - 35⁴) / (83000 N/mm² (80 mm)³))]^(1/2)f = (1/2π) [(2.5 × 10⁴ Nm/rad) / (L₀) (18.12)]^(1/2)f = 25.7 / L₀^(1/2)...(3)

Now, if we assume that the air-screw mass is infinite, then the moment of inertia of the air-screw is infinite.

Therefore, the formula for natural frequency of torsional vibration in this case is:

f = (1/2π) [(K/L) (J/GD)]^(1/2)Substituting I = ∞ in the above formula, we get:

f = (1/2π) [(K/L) (J/GD + J/∞)]^(1/2)f = (1/2π) [(K/L) (J/GD)]^(1/2)f = 25.7 / L₀^(1/2)

So, in this case also the frequency is the same.

Therefore, the percentage change in frequency is 0%.Hence, the natural frequency of torsional vibration of the custen is given by f = 25.7 / L₀^(1/2) and the percentage change in frequency is 0%.

Answers

The constant of proportionality between earnings and time in hours is equal to 21.1.

How to determine the constant of proportionality?

In Mathematics, a proportional relationship is a type of relationship that generates equivalent ratios and it can be modeled or represented by the following mathematical expression:

y = kx

Where:

x represents the time (hours).y represents the earnings (dollars).k represents the constant of proportionality.

In order to have a proportional relationship and equivalent ratios, the variables x and y must have the same constant of proportionality.

Next, we would determine the constant of proportionality (k) as follows:

y = kx

Constant of proportionality (k) = y/x

Constant of proportionality (k) = 274.30/13 = 337.60/16 = 464.20/22

Constant of proportionality (k) = 21.1
