A cylindrical object is 3.13 cm in diameter and 8.94 cm long and weighs 60.0 g. The density of the cylindrical object is 0.849 g/cm^3.

To calculate the density, we first need to find the volume of the cylindrical object. The volume of a cylinder can be calculated using the formula V = πr^2h, where r is the radius (half of the diameter) and h is the height (length) of the cylinder.

Given that the diameter is 3.13 cm, the radius is half of that, which is 3.13/2 = 1.565 cm. The length of the cylinder is 8.94 cm.

Using the values obtained, we can calculate the volume: V = π * (1.565 cm)^2 * 8.94 cm = 70.672 cm^3.

The density is calculated by dividing the weight (mass) of the object by its volume. In this case, the weight is given as 60.0 g. Therefore, the density is: Density = 60.0 g / 70.672 cm^3 = 0.849 g/cm^3.

Answer: True

Step-by-step explanation: because bias can lead to personal errors

Answer:

g(x) = 4x - 23

Step-by-step explanation:

We will assume a linear function for g(x)

This will be of the form g(x) = ax + b where a and b are constants

Given the info,

g(3) = a(3) + b = -11

g(7) = a(7) + b = 5

Thus we have two equations in a and b
3a + b = -11  [1]
7a + b = 5    [2]

Subtract [1] from [2]:
7a + b - (3a + b) = 5 - (-11)
7a + b - 3a - b = 5 + 11

4a = 16

a = 4

Substitute for a in equation [2]:

4(7) + b = 5
28 + b = 5

b = 5-28 = -23

So equation of g(x) is
g(x) = 4x - 23

By using the concept of depreciation, it is obtained that

New population  after 9 years = 24012

What is Depreciation?

Depreciation is the decrease in the value of a population or any asset over a period of time at a certain rate.

The concept of depreciation has been used here

Original population = 28800

Rate of decrease of population = 2%

Time = 9 years

New population  after 9 years = \(28800(1 - \frac{2}{100})^9\)

                                                  = \(28800({1 - \frac{1}{50})^9\\\)

                                                  = \(28800(\frac{49}{50})^9\)

                                                  = 24011.94

                                                  = 24012

To calculate the monthly principal + interest payments for a house with a down payment and a mortgage using an Excel formula, you can use the PMT function. Here's how:

Calculate the loan amount by subtracting the down payment from the house cost. In this case, the down payment is 25% of $300,000, so it would be $75,000.
  Loan Amount = $300,000 - $75,000 = $225,000    

Determine the monthly interest rate by dividing the annual interest rate by 12. In this case, the annual interest rate is 2.75%, so the monthly interest rate would be 2.75% / 12 = 0.00229.

Determine the loan term in months. Since it's a 30-year mortgage, the loan term would be 30 * 12 = 360 months.

Use the PMT function in Excel to calculate the monthly principal + interest payment.
  Monthly Payment = -PMT(0.00229, 360, 225000)

The negative sign is used because the payment is an outgoing cash flow.

By using this formula in Excel, you can find the monthly principal + interest payments for your mortgage. Remember to adjust the interest rate, loan amount, and loan term if they differ from the example provided.

To calculate the monthly principal + interest payments using an Excel formula, you can use the PMT function by inputting the appropriate parameters: the monthly interest rate, loan term in months, and loan amount.

we need 31/2 pounds mirepoix to make 31/2 gallons of soup.

let we need x% (percent) of mirepoix to make 1 gallon of soup

given we have 1 pound of mirpoix which yeilds 1 gallon soup of soup

so total amount of mirepoix that required in the solution is = \(\frac{x}{100} *1 pound\)

so x/100 = 1 gallon / pound

we will use this equation for further calculation

let we need y pounds of mirepoix to make 31/2 gallon of soup  ans we know that x% of mirepoix is required for this solution.

so \(\frac{x}{100} * y = 31/2\)

ans in the above equation x/100 =1 gallon / pound

so  1 * y= 31 /2

The linear equation parallel to y = 4x - 5 that pass through (2, 5) is:

y = 4x - 3

We know that the general linear equation is:

y = a*x +b

Where a is the slope and b is the y-intercept.

And two lines are parallel if the lines have the same slope and different y-intercept.

We want to find a line parallel to:

y = 4x - 5

Then the line will be like:

y = 4x + b

Now we also want this line to pass through the point (2, 5)

Error :    (8.25 - 7.5)

% error :    ( 8.25-7.5) / 8.25    * 100%  = 9.1 %

Jim's percent error is 9.09%.

What is the percentage error?

The percentage error is given as the difference between the actual value and the estimated value divided by the actual value, multiplied by 100%.

The percentage error is a relative value that compares the actual value and the estimated value to explain any deviations.

Estimated width of wall = 7.5 feet

The actual width of the wall = 8.25 feet

The difference in estimate = (8.25 - 7.5) = 0.75 feet

Percentage Error = (0.75/8.25 x 100) = 9.09%

Thus, we can conclude that Jim made a percentage error of 9.09%  in his estimate of the width of the wall.

\(Ratio = 2\)

Considering Side of A = 3 and Side of B = 5

The label covers 11,936 over 7 square centimeters of the wheel.

The cylindrical-shaped wheel of cheese has a radius of 22 centimeters and a height of 16 centimeters. The label covers the entire wheel except the circular top and bottom. Therefore, the area covered by the label is the lateral surface area of the cylinder.

The lateral surface area of a cylinder can be calculated using the formula 2πrh, where r is the radius of the base, h is the height, and π is approximately equal to 22/7.

Substituting the given values, we get:

Lateral surface area = 2 × (22/7) × 22 × 16

Lateral surface area = (44/7) × 22 × 16

Lateral surface area = 1,936 square centimeters (approx.)

Therefore, the label covers approximately 1,936/7 square centimeters of the wheel. The closest option is (C) 1,936 over 7 square centimeters.

The value of f(5) in the function below is 8. (option-a)

The function `f(x) = 1/2*x` means that the output `f(x)` is equal to half of the input `x`.

To find `f(5)`, we substitute `5` for `x` in the function:

`f(5) = 1/2*5 = 5/2`

Therefore, the value of `f(5)` is `5/2`, which is an irrational number, and the answer is not listed among the options provided.

However, if we assume that the answer choices contain errors and we are asked to find the closest listed approximation to `5/2`, we can use commonly known approximations such as 3.14 for π to evaluate:

`5/2 ≈ 2.5`

a. The given differential equation is exact since the partial derivatives of the equation are equal.

b. The general solution to the differential equation is x^3y + x + y + C2 = 0, where C2 is a constant of integration.

To determine if the given differential equation is exact, we need to check if the partial derivatives of the equation satisfy the condition of equality.

The given differential equation is:

(3x^2y + 1)dx + (x^3 + 1)dy = 0

Taking the partial derivative with respect to y of the term involving dx:

∂/∂y (3x^2y + 1) = 3x^2

Taking the partial derivative with respect to x of the term involving dy:

∂/∂x (x^3 + 1) = 3x^2

Since the two partial derivatives are equal, the differential equation is exact.

To find the general solution to the exact differential equation, we integrate the terms separately and add a constant of integration. Integrating the term involving dx with respect to x gives:

∫ (3x^2y + 1)dx = x^3y + x + C1(y),

where C1(y) represents the constant of integration with respect to y.

Next, we differentiate the result of the integration with respect to y to find C1(y):

d/dy (x^3y + x + C1(y)) = x^3 + C1'(y).

Comparing this with the term involving dy in the original differential equation, we have:

x^3 + C1'(y) = x^3 + 1

This implies that C1'(y) = 1, and integrating C1'(y) gives:

∫ dC1(y) = ∫ 1 dy

C1(y) = y + C2,

where C2 is a constant of integration.

Therefore, the general solution to the given exact differential equation is:

x^3y + x + y + C2 = 0.

This is the implicit form of the general solution.
