Answer:
Step-by-step explanation:
The volume of the given prism is 9.936 cubic meters, To calculate the volume of a right rectangular prism, we need to multiply its length, width, and height together.
Given that the length of the prism is 4.8 meters, the width is 2.3 meters, and the height is 0.9 meters, we can calculate the volume using the formula:
Volume = length x width x height
Volume = 4.8 m x 2.3 m x 0.9 m
Volume = 9.936 m^3
Therefore, the volume of the right rectangular prism is 9.936 cubic meters.
It is important to note that when we calculate volume, we are dealing with a three-dimensional space, and the units we use must be cubed (m^3 in this case). This is because we are measuring the amount of space occupied by the object in all three dimensions.
In summary, to find the volume of a right rectangular prism, we simply multiply its length, width, and height together. In this case, the volume of the given prism is 9.936 cubic meters.

The amount of total and per-unit overhead allocated to each of the three products using overhead rate is equal to,
Total Per Unit Factory Overhead , Cost Factory Overhead Cost
Flutes $530 $1,060,000
Clarinets $795 $1,192,500
Oboes $397.5 $695,625
Total $1,722.5 $2,948,125
Budgeted factory overhead cost = $2,948,125
The single plantwide overhead rate
= Dividing the budgeted factory overhead cost by the total budgeted direct labor hours.
For this,
Flutes= 2,000×2
= 4,000 hours
Clarinets= 1,500×3
= 4,500 hours
Oboes= 1,750×1.5
= 2,625 hours
Total direct labor hours = 11,125
Substitute the value we have,
⇒ Single plantwide overhead rate = $2,948,125 / (2,000 x 2.0 + 1,500 x 3.0 + 1,750 x 1.5)
= $2,948,125 / 11,125
= $265 per direct labor hour
To allocate overhead to each product
=Multiply the overhead rate by the budgeted direct labor hours per unit for each product.
Substitute the value we have,
Flutes,
$265 x 2.0 = $530 total overhead cost, $265 per unit
Clarinets,
$265 x 3.0 = $795 total overhead cost, $265 per unit
Oboes,
$265 x 1.5 = $397.5 total overhead cost, $265 per unit
And
Total factory overhead cost allocated = Estimated manufacturing overhead rate× Actual amount of allocation base
For,
Flutes
= 4,000× 265
= $1,060,000
Clarinets
= 4,500×265
= $1,192,500

Question 3 Next ſsin"" e cos"" Evaluate the indefinite integral xdu
But there seems to be some missing information in your question. Please provide more context or details so that I can assist you accurately.
Hi! I'd be happy to help you evaluate the indefinite integral. Based on the provided terms and information, it seems like you want to evaluate the following integral:
∫x * sin(e * cos(x)) dx
To solve this integral, we can use integration by parts, which is defined as:
∫u dv = u * v - ∫v du
Let's choose u = x and dv = sin(e * cos(x)) dx. Then, we need to find du and v:
du = dx
v = ∫sin(e * cos(x)) dx
Unfortunately, the integral for v does not have a simple closed-form expression. However, you can use numerical methods or software (like Wolfram Alpha) to approximate it. Once you have an approximation for v, you can plug it back into the integration by parts formula to obtain an approximation of the original integral:
∫x * sin(e * cos(x)) dx ≈ x * v - ∫v dx
Keep in mind that this is an indefinite integral, so don't forget to add the constant of integration, C, to your final answer.

Will any ramp with one angle of 4. 8 degrees have a slope ratio of 1 : 12?
Yes, any ramp with an angle of 4.8 degrees will have a slope ratio of 1:12.
The slope ratio is the ratio of the vertical rise to the horizontal run of the ramp, and it is equivalent to the tangent of the angle of inclination of the ramp.
The tangent of 4.8 degrees is approximately 0.0084, which means that for every 1 unit of vertical rise, there is 0.0084 units of horizontal run. To convert this to a ratio, we can multiply both sides by 100 to get:
1 unit of rise : 100 x 0.0084 = 0.84 units of run
Simplifying this ratio by dividing both sides by 0.84, we get:
1 unit of rise : 1.19 units of run
which is equivalent to a slope ratio of 1:12 (since 12 = 1/0.084). Therefore, any ramp with an angle of 4.8 degrees will have a slope ratio of 1:12.

Solve the separable differential equation for u. du dt e2u+9t Use the initial condition u(0) = 4. = U =
The solution to the differential equation with the given initial condition is:
[tex]u = -1/2 * ln(-2/9 * e^{(9t)} + 4/9 * e^{(-8)} + 2/9)[/tex]
How to solve the separable differential equation?To solve equation, we can separate the variables and write:
[tex]1/e^{(2u)} du = e^{(9t)} dt[/tex]
Integrating both sides, we get:
[tex]\int 1/e^{(2u)} du = \int e^{(9t)} dt[/tex]
Integrating the left side requires the substitution v = 2u, dv/du = 2, and du = dv/2, which gives:
[tex]\int 1/e^{(2u)} du = \int 1/2 * 1/e^v dv = -1/2 * e^{(-2u)}[/tex]
Integrating the right side gives:
[tex]\int e^{(9t)} dt = 1/9 * e^{(9t)}[/tex]
Substituting these integrals back into the original equation, we get:
[tex]-1/2 * e^{(-2u)} = 1/9 * e^{(9t)} + C[/tex]
where C is the constant of integration.
We can solve for the constant of integration using the initial condition u(0) = 4:
[tex]-1/2 * e^{(-24)} = 1/9 * e^{(90)} + C[/tex]
[tex]-1/2 * e^{(-8)} = 1/9 + C[/tex]
[tex]C = -1/2 * e^{(-8)} - 1/9[/tex]
Therefore, the solution to the differential equation [tex]du/dt = e^{(2u+9t)}[/tex] with initial condition u(0) = 4 is:
[tex]-1/2 * e^{(-2u)} = 1/9 * e^{(9t)} - 1/2 * e^{(-8)} - 1/9[/tex]
Solving for u, we get:
[tex]e^{(-2u)} = -2/9 * e^{(9t)} + 4/9 * e^{(-8)} + 2/9[/tex]
Taking the natural logarithm of both sides, we get:
[tex]-2u = ln(-2/9 * e^{(9t)} + 4/9 * e^{(-8)} + 2/9)[/tex]
Dividing by -2, we get:
[tex]u = -1/2 * ln(-2/9 * e^{(9t)} + 4/9 * e^{(-8)} + 2/9)[/tex]
Therefore, the solution to the differential equation with the given initial condition is:

The function f(x) = 2x^3 +30x^2 – 54x +5 has one local minimum and one local maximum. This function has a local minimum at x = with value
and a local maximum at x =
with value
The local maximum is at x = -9 with a value of 2575, and the local minimum is at x = 1 with a value of -17.
To find the local minimum and maximum of the given function, we need to find its critical points, where the derivative is zero or undefined.
[tex]f(x) = 2x^3 + 30x^2 - 54x + 5[/tex]
[tex]f'(x) = 6x^2 + 60x - 54[/tex]
Setting f'(x) = 0, we get:
[tex]6x^2 + 60x - 54 = 0[/tex]
[tex]x^2 + 10x - 9 = 0[/tex]
(x + 9)(x - 1) = 0
x = -9 or x = 1
Now, we need to determine if these critical points correspond to local minimum or maximum.
To do so, we can use the second derivative test. We calculate the second derivative of f(x):
f''(x) = 12x + 60
At x = -9:
f''(-9) = 12(-9) + 60 = -48 < 0
This means that f(x) has a local maximum at x = -9.
At x = 1:
f''(1) = 12(1) + 60 = 72 > 0
This means that f(x) has a local minimum at x = 1.
To find the values of the local minimum and maximum, we plug in the corresponding x-values into the original function:
[tex]f(-9) = 2(-9)^3 + 30(-9)^2 - 54(-9) + 5 = 2575[/tex]
[tex]f(1) = 2(1)^3 + 30(1)^2 - 54(1) + 5 = -17[/tex]

ý is the predicted fare and x is the distance, in miles.
O $102. 50
O $435. 00
O $225. 00
O $330. 00
The fare for this flight would be: $225.
How we get the fare for the flight?To determine the fare for the flight that was 350 miles with a residual of -105, we need to use the least-squares regression equation:
ý = 102.50 + 0.65x
where ý is the predicted fare and x is the distance in miles.
We know that the distance for this flight is 350 miles, so we can substitute x = 350 into the equation:
ý = 102.50 + 0.65(350)
ý = 102.50 + 227.50
ý = 330
Therefore, the predicted fare for this flight is $330.
The residual of -105 means that the actual fare for this flight was $105 less than the predicted fare based on the regression line. Therefore, the actual fare for this flight would be:

How to do measure of arc?Without additional information, it is not possible to determine the measure of arc CAD with certainty. The measure of an arc depends on the central angle that subtends it.
If the central angle is known, the measure of the arc can be calculated using the formula: measure of arc = (central angle / 360) x circumference of the circle. However, without knowing the central angle, we cannot determine the measure of arc CAD.
Therefore, we need to be provided with additional information such as the measure of another angle that is related to the central angle, or the length of a chord that subtends the arc in order to determine the central angle and the measure of arc CAD.

The fraction, David used 13/8 cups of blueberries for the pancakes.
Let's solve it step-by-step using the given information.
1. David has 3 1/2 cups of blueberries.
2. He uses 1/4 cup for a breakfast smoothie.
3. He uses 1/2 of the remaining blueberries for pancakes.
Step 1: Calculate the remaining blueberries after making the smoothie.
3 1/2 - 1/4 = (7/2) - (1/4)
To subtract the fractions, they need a common denominator, which in this case is 4.
(7/2) * (2/2) - (1/4) = (14/4) - (1/4) = 13/4 cups
Step 2: Calculate the amount of blueberries used for the pancakes.
David uses 1/2 of the remaining blueberries for the pancakes, so:
(13/4) * (1/2) = 13/8 cups
David uses 13/8 cups of blueberries for the pancakes.

4/625 x 625/9 cross cancellation
Answer:
Step-by-step explanation:
4/625 x 625/9 = 4 x 1 / 5 x 5 x 5 x 1 = 4/625. The cross cancellation did not change the result.
A mechanic had412 gallons of motor oil at the start of the day. At the end of the day, only 5 pints remained
The mechanic used 412 - 411.375 = 0.625 gallons of motor oil during the day.
A mechanic had 412 gallons of motor oil at the start of the day and ended up with only 5 pints of oil remaining.To solve this problem, we need to convert both measurements to the same unit.
1 gallon = 8 pints (since there are 8 pints in a gallon)
So the mechanic started with:
412 gallons * 8 pints/gallon = 3,296 pints
And ended with:
5 pints
To find how much motor oil the mechanic used during the day, we can subtract the ending amount from the starting amount:
3,296 pints - 5 pints = 3,291 pints
To convert this back to gallons, we divide by 8:
3,291 pints / 8 pints/gallon = 411.375 gallons (rounded to three decimal places)

Question 1 (Essay Worth 30 points) 2.

Explain why your answer is so close to 1. (10 points) x2n+1 263 Part C: The series { (-1)" has a partial sum S. when x = 1. What is an interval, |S - S5l = R5| for which the actual sum exists? 2n +1 315 Provide an exact answer and justify your conclusion. (10 points) n=0
Part A: The coefficient of the 4th degree term in the Taylor polynomial for f(x) = sin(4x) centered at x = 0 is -1/3! = -1/6.
Part B: Using a 4th degree Taylor polynomial for sin(x) centered at x = 0, we can write g(x) = sin(0.8) ≈ P4(0.8), where P4(0.8) is the 4th degree Taylor polynomial for sin(x) evaluated at x = 0.8.
Evaluating P4(0.8) using the formula for the Taylor series coefficients of sin(x), we get P4(0.8) = 0.8 - 0.008 + 0.00004 - 0.0000014 ≈ 0.78333. This estimate is very close to 1 because sin(0.8) is close to 1, and the Taylor series for sin(x) converges very rapidly for values of x close to 0.
Part C: The series { (-1)n / (2n + 1) } has a partial sum S when x = 1. To find an interval |S - S5| = R5| for which the actual sum exists, we can use the alternating series test. The alternating series test states that if the terms of a series alternate in sign, decrease in absolute value, and approach zero, then the series converges.
Since the terms of the series { (-1)n / (2n + 1) } alternate in sign and decrease in absolute value, we know that the series converges. To find an interval |S - S5| = R5|, we can use the remainder formula for alternating series, which states that |Rn| ≤ a_n+1, where a_n+1 is the first neglected term in the series.
Since the terms of the series decrease in absolute value, we know that a_n+1 ≤ |a_n|. Therefore, we have |R5| ≤ |a6| = 1/7!, which means that the actual sum of the series exists in the interval S - 1/7! ≤ S5 ≤ S + 1/7!. Therefore, an interval for which the actual sum exists is [S - 1/7!, S + 1/7!].

The surface area of the cone is approximately 793.10 cm².
What is cone?
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (usually circular) to a point called the apex or vertex.
What is area of cone?
The surface area of a cone is given by the formula:
Surface Area = πr² + πrℓ
where r is the radius of the circular base and ℓ is the slant height of the cone.
According to given information:To find the surface area of a cone, we need to find the area of its base and the area of its lateral surface and then add them together.
The formula for the lateral surface area of a cone is given by:
L = πrℓ
where r is the radius of the base and ℓ is the slant height of the cone.
The formula for the area of the base of a cone is given by:
B = πr²
where r is the radius of the base.
Given the slant height ℓ = 19 and the radius r = 9, we can find the lateral surface area of the cone as follows:
L = πrℓ
= π(9)(19)
≈ 538.63 cm²
Next, we can find the area of the base of the cone as follows:
B = πr²
= π(9)²
≈ 254.47 cm²
Therefore, the surface area of the cone is:
A = B + L
≈ 793.10 cm²
So, the surface area of the cone is approximately 793.10 cm².
