Given statement solution is :- The actual length of the part is 3751/64 inches.

To find the length of the actual part, you can use the scale factor and the length of the part on the drawing. The formula for finding the actual length is:

Actual Length = Length on Drawing × Scale Factor

In this case, the length on the drawing is given as 3 7/8 inches, and the scale factor is given as 15 ¹/8. Let's calculate the actual length:

Length on Drawing = 3 7/8 inches = (3 × 8 + 7) / 8 = 31/8 inches

Scale Factor = 15 ¹/8

Now we can substitute the values into the formula:

Actual Length = (31/8 inches) × (15 ¹/8)

To perform the multiplication, we can convert the mixed fraction into an improper fraction:

15 ¹/8 = (15 × 8 + 1) / 8 = 121/8

Now we can multiply the fractions:

Actual Length = (31/8) × (121/8)

To multiply fractions, we multiply the numerators together and the denominators together:

Actual Length = (31 × 121) / (8 × 8)

Actual Length = 3751 / 64

Therefore, the actual length of the part is 3751/64 inches.

On the interval 3 ≤ x ≤ ∞, function g has a greater rate of growth.

In Mathematics and Geometry, a steeper slope simply means that the slope of a line is bigger than the slope of another line. This ultimately implies that, a graph with a steeper slope has a greater (faster) rate of change in comparison with another graph.

In this context, we can reasonably infer and logically deduce that the graph of function g(x) would be steeper than the graph of function f(x) because a slope of 3 is greater than a slope of -2.

Answer:

b > -3, so 6b > -18 is the correct answer.

To solve the equation (17-3x)/(x-3)(x-4) = (x+1)/(x-4), we need to first simplify both sides of the equation and then find the values of x that satisfy the equation.

Let's start by simplifying the equation. We notice that both sides have a common denominator of (x-4), so we can eliminate it by multiplying both sides of the equation by (x-4):

[tex](x-4) * (17-3x) = (x-4) * (x+1)[/tex]

Expanding the equation, we get:

[tex]17x - 4x - 3x^2 + 12 = x^2 - 3x + x - 4[/tex]

Simplifying further, we have:

[tex]-3x^2 + 13x + 12 = x^2 - 2x - 4[/tex]

Bringing all terms to one side, we get:

[tex]-3x^2 - x^2 + 13x + 2x + 12 + 4 = 0[/tex]

Combining like terms, we have:

[tex]-4x^2 + 15x + 16 = 0[/tex]

Now, we have a quadratic equation. To solve it, we can either factor it, complete the square, or use the quadratic formula. However, the given equation is not easily factored.

Using the quadratic formula, x = [tex](-b ± \sqrt(b^2 - 4ac)) / (2a),[/tex] where a = -4, b = 15, and c = 16, we can calculate the solutions for x.

x = (-15 ± √(15^2 - 4 * -4 * 16)) / (2 * -4)

x = (-15 ± √(225 + 256)) / -8

x = (-15 ± √481) / -8

Therefore, the solutions for x are:

x ≈ 4.28 and x ≈ -0.53

These are the values of x that satisfy the given equation (17-3x)/(x-3)(x-4) = (x+1)/(x-4).

Elsa is approximately 65.0 inches tall.

To find Elsa's height, we need to determine the z-score corresponding to the 75th percentile. The 75th percentile is the value below which 75% of the population falls.

Using the z-score formula: z = (x - μ) / σ, where x is the observed value, μ is the mean, and σ is the standard deviation, we can rearrange the formula to solve for x.

Plugging in the given values, we have z = (x - 63.5) / 2.5. To find the z-score corresponding to the 75th percentile, we need to find the z-score associated with the area of 0.75 under the standard normal distribution curve.

Using a standard normal distribution table or a calculator, we find that the z-score is approximately 0.6745.

Substituting the z-score into the formula, we have 0.6745 = (x - 63.5) / 2.5. Solving for x, we find x ≈ 65.0 inches. Therefore, Elsa is approximately 65.0 inches tall.

In a normally distributed population, we can use z-scores to find percentiles and vice versa. By finding the z-score corresponding to the 75th percentile (which is 0.75), we can determine the height value associated with that percentile.

The z-score represents the number of standard deviations an observation is away from the mean. In this case, Elsa's height is taller than 75% of the population, so her height corresponds to the 75th percentile.

By rearranging the z-score formula and substituting the given values, we can solve for Elsa's height. In this case, the resulting value is approximately 65.0 inches. This means that Elsa's height is greater than the height of 75% of adult women in the United States.

To find the particular solution of the differential equation y''' - 4y' = t + 3cos(t) + e^(-2t), we assume a general form for the solution. After solving, we obtain y(t) = -1/2t^2 + (1/2)sin(t) - (1/8)e^(-2t) + (1/16)te^(-2t) + C1 + C2t + C3e^(-2t), where C1, C2, and C3 are arbitrary constants.

To find the particular solution of the given differential equation y''' - 4y' = t + 3cos(t) + e^(-2t), we will use the method of undetermined coefficients.

Guess the form of the particular solution.

Since the right-hand side of the equation consists of a polynomial term (t) and trigonometric terms (cos(t)), as well as an exponential term (e^(-2t)), we will guess a particular solution of the form:

y_p(t) = At^2 + Bt + Ccos(t) + De^(-2t)

Calculate the derivatives of the guessed solution.

y'_p(t) = 2At + B - Csin(t) - 2De^(-2t)

y''_p(t) = 2A - Ccos(t) + 4De^(-2t)

y'''_p(t) = Csin(t) + 8De^(-2t)

Substitute the guessed solution and its derivatives into the original differential equation.

Substituting into the equation:

(Csin(t) + 8De^(-2t)) - 4(2A - Ccos(t) + 4De^(-2t)) = t + 3cos(t) + e^(-2t)

Simplifying the equation, we get:

Csin(t) + 8De^(-2t) - 8A + 4Ccos(t) - 16De^(-2t) = t + 3cos(t) + e^(-2t)

Collect like terms and solve for the coefficients.

Matching the coefficients of the terms on both sides, we have:

Csin(t) + 8De^(-2t) = 0 (1)

-8A + 4Ccos(t) - 16De^(-2t) = 3cos(t) (2)

0t + 0 + 0 - 8A + 0 - 16De^(-2t) = t + e^(-2t) (3)

From equation (1), we have C = 0, and from equation (2), we get C = 3/4.

Equating the exponential terms in equation (3), we have -16De^(-2t) = e^(-2t), which gives D = -1/16.

Finally, from equation (3), we find -8A = t, which implies A = -t/8.

Therefore, the particular solution is:

y_p(t) = (-t/8)t^2 + Bt + (3/4)cos(t) - (1/16)e^(-2t)

where B is an arbitrary constant.

Answer:

The given differential equation is a third-order, non-homogeneous, linear differential equation. To find its particular solution, we can use the method of undetermined coefficients. This method involves assuming a form for the particular solution based on the form of the non-homogeneous term, and then determining the values of the coefficients by substituting the assumed form into the differential equation.

In this case, the non-homogeneous term is `t + 3cos t + e^-2t`. Since this term contains a polynomial of degree 1, a cosine function, and an exponential function, we can assume that the particular solution will have the form `y_p = At + B + Ccos t + Dsin t + Ee^-2t`, where `A`, `B`, `C`, `D`, and `E` are constants to be determined.

To determine the values of these constants, we can substitute the assumed form for `y_p` into the given differential equation and equate coefficients. This will result in a system of linear equations that can be solved for `A`, `B`, `C`, `D`, and `E`. Once these values are determined, we can write down the particular solution as `y_p = At + B + Ccos t + Dsin t + Ee^-2t`.

The simplified form of -20/2(7 2/3) is -230/3.

To solve the expression -20/2(7 2/3), we need to follow the order of operations, which states that we should perform the operations inside parentheses first, then any multiplication or division from left to right, and finally any addition or subtraction from left to right.

First, let's convert the mixed number 7 2/3 to an improper fraction.

7 2/3 = (7 * 3 + 2) / 3 = 23/3

Now, let's substitute the value back into the expression:

-20/2 * (23/3)

Next, we simplify the multiplication:

-10 * (23/3)

To multiply a fraction by a whole number, we multiply the numerator by the whole number:

-10 * 23 / 3

Now, we perform the multiplication:

-230 / 3

Therefore, the simplified form of -20/2(7 2/3) is -230/3.

The expression cos x/cot x simplifies to sin x by utilizing trigonometric identities and canceling out the common cosine terms in the numerator and denominator.

To simplify the expression cos x/cot x, we need to utilize trigonometric identities. Cotangent (cot x) is the reciprocal of the tangent function, so we can rewrite cot x as 1/tan x.

Now, substituting 1/tan x for cot x in the expression cos x/cot x, we have:

cos x / (1/tan x)

To divide by a fraction, we multiply by its reciprocal. Therefore, multiplying cos x by tan x, we get:

(cos x)(tan x)

Using the identity tan x = sin x / cos x, we can substitute sin x / cos x for tan x:

Based on an annual income of $53,698 and deductions for FICA, federal tax withholding, and state tax withholding, the calculated allowed housing expense is approximately $11,572.84.

To calculate the allowed housing expense for the year, we need to determine the net income after deducting FICA (7.65%), federal tax withholding (11.5%), and state tax withholding (9%) from the annual income of $53,698.

First, let's calculate the deductions:

FICA deduction: 7.65% of $53,698 = $4,111.97

Federal tax withholding: 11.5% of $53,698 = $6,177.07

State tax withholding: 9% of $53,698 = $4,832.82

Next, subtract the deductions from the annual income:

Net income = $53,698 - $4,111.97 - $6,177.07 - $4,832.82 = $38,576.14

The allowed housing expense is generally recommended to be around 30% of the net income. To calculate this, we multiply the net income by 0.3:

Allowed housing expense = 0.3 * $38,576.14 = $11,572.84

However, it appears there is a discrepancy between the provided answer of $10,802.96 and the calculated value of $11,572.84. The difference could be due to rounding or other factors not accounted for in the given information. To reconcile this difference, we would need additional details or clarification.
