Answer: x = 18

Step-by-step explanation:

1) 100% - 54.5% = 45.5%.

2) 45.5/100 = 0.455.

3) 0.455 * X = 8.19g.

4) x = 8.19/0.455.

5) x = 18.

To find the mass and center of mass of the solid bounded by the paraboloid z = 8x^2 + 8y^2 and the plane z = a, we can use cylindrical coordinates.

In cylindrical coordinates, the paraboloid can be expressed as z = 8r^2, where r is the radial distance and z is the height.

To find the mass of the solid, we need to integrate the density function over the volume of the solid. Since the solid has constant density k, the mass can be expressed as:

M = ∭ k dv

Using cylindrical coordinates, the volume element (dv) is given by dv = r dz dr dθ.

The bounds for the integral are as follows:

r: from 0 to √(a/8) (due to the paraboloid equation z = 8r^2)

θ: from 0 to 2π (to cover the entire azimuthal angle)

z: from 0 to a (due to the plane z = a)

Now, let's evaluate the integral for the mass:

M = ∭ k dv = ∫[z=0 to a] ∫[θ=0 to 2π] ∫[r=0 to √(a/8)] k r dz dr dθ

The integration process will yield the mass M of the solid.

To find the center of mass, we need to evaluate the triple integral:

(x_cm, y_cm, z_cm) = (1/M) ∭ (x, y, z) k dv

Where (x_cm, y_cm, z_cm) represent the coordinates of the center of mass.

The integrals for each coordinate can be set up similarly to the mass integral, using the appropriate expressions for x, y, and z in terms of cylindrical coordinates. Then, divide each integral by the mass M to obtain the coordinates of the center of mass.

Note that the calculations can be quite involved, so it's recommended to use software or a computer algebra system to perform the integrations and simplify the expressions.

The point estimate of the difference in the population mean exercised between underclassmen and upperclassmen is 0.16 hours.

In this case, we are estimating the difference in population means between two groups - upperclassmen and underclassmen. The point estimate is calculated by subtracting the sample mean of the underclassmen from the sample mean of the upperclassmen, which gives us

0.76 - 0.60 = 0.16.
the point estimate of the difference in population mean exercised between underclassmen and upperclassmen is 0.16 hours, which was calculated by subtracting the sample mean of underclassmen from the sample mean of upperclassmen.
Point Estimate = (Sample Mean of Upperclassmen) - (Sample Mean of Underclassmen)
Point Estimate = (0.76) - (0.60)
Point Estimate = 0.16

Hence, the point estimate of 0.16 suggests that, on average, upperclassmen exercised 0.16 hours more than underclassmen in the past 24 hours. This is a rough estimate of the difference between the two population means based on the provided sample data.

Question 1a

To calculate the book value at the end of the first year using straight-line depreciation, we need to determine the annual depreciation expense first. The straight-line method assumes that the asset depreciates by an equal amount each year over its useful life. Therefore, we can use the following formula to calculate the annual depreciation:

Annual Depreciation = (Cost - Salvage Value) / Useful Life

Substituting the given values, we get:

Annual Depreciation = ($200,000 - $20,000) / 10 years = $18,000 per year

This means that the tractor will depreciate by $18,000 each year for the next 10 years.

To determine the book value at the end of the first year, we need to subtract the depreciation expense for the year from the original cost of the tractor. Since one year has passed, the depreciation expense for the first year will be:

Depreciation Expense for Year 1 = $18,000

Therefore, the book value of the tractor at the end of the first year will be:

Book Value = Cost - Depreciation Expense for Year 1

= $200,000 - $18,000

= $182,000

So the book value of the tractor at the end of the first year, December 31, 2022, using straight-line depreciation is $182,000. so the answer is D

Question 1(b)

To determine the farmer's noncurrent liabilities, we need to use the information provided to calculate the total liabilities and then subtract the current liabilities from it. Here's the step-by-step solution:

Calculate the total current liabilities using the current ratio:

Current Ratio = Current Assets / Current Liabilities

2 = $80,000 / Current Liabilities

Current Liabilities = $80,000 / 2

Current Liabilities = $40,000

Calculate the total liabilities using the debt/equity ratio:

Debt/Equity Ratio = Total Liabilities / Owner Equity

1.0 = Total Liabilities / $100,000

Total Liabilities = $100,000 * 1.0

Total Liabilities = $100,000

Subtract the current liabilities from the total liabilities to get the noncurrent liabilities:

Noncurrent Liabilities = Total Liabilities - Current Liabilities

Noncurrent Liabilities = $100,000 - $40,000

Noncurrent Liabilities = $60,000

Therefore, the farmer's noncurrent liabilities are $60,000. so the answer is B.

Answer: -15

Step-by-step explanation:

Let the unknown number be 'x'

Using the statement we can form the equation:

4 + x = -11

Now, solve the above equation to get :

4 + x = -11

x = -11 -4

x = -15

The number is -15. To check our answer, substitute for x :

4 + (-15) = -11

4 - 15 = -11

The above equation is correct. Therefore, the number is -15.

Since you have sales tax, you would do a 10% sales tax for 15 dollar

10/100 = x/15

Therefore you will calculate x and 100 divided by 15 which would be 6.6 repeated

You would round to the nearest tenth and get 6.6 then you would add 56.4 as in the tip+ month airtime usage and get 63 dollars.

A general formula that gives all the times when the voltage will be 0 is t = ±√((pπ)/10)

To find the general formula for the times when the voltage will be 0, we need to analyze the given equation: V(t) = 12sin(5t²). Since V(t) represents the voltage at time t, we want to find the values of t for which V(t) = 0. This will occur when the sine function equals 0.

The sine function, sin(x), is equal to 0 when its argument x is a multiple of π. Mathematically, this can be expressed as:

sin(x) = 0 ⟺ x = nπ, where n is an integer (0, ±1, ±2, ...)

In our case, the argument of the sine function is 5t². Thus, we want to find values of t for which:

5t² = nπ, where n is an integer.

Now, let's solve this equation for t:

t² = (nπ)/5

t = ±√((nπ)/5)

Since the question asks for a formula in terms of p, let's define p as an integer such that p = 2n (n can be any integer). Thus, the formula becomes:

t = ±√((pπ)/10)

This formula represents the general sequence of times t (in milliseconds) when the voltage V(t) will be equal to 0. Here, p is an even integer (0, ±2, ±4, ...) representing different instances when the voltage is zero.

The coordinates of the point would be (0, 5).

A single point or group of points that indicate the values of a mathematical function or experimental data are referred to as a plot in an x-y axis plot.

A plot is identified by its x-coordinate and y-coordinate, which determine its location on the Cartesian coordinate system.

"3, 5 acrossed the y axis" means that the point is located at a distance of 3 units to the right of the y-axis and 5 units above the x-axis. So the coordinates of the point would be (3, 5).

On the other hand, if the point is over the x-axis, it means that it is located at a distance of 5 units above the x-axis. The x-coordinate of the point would be 0 because it lies on the x-axis. Therefore, the coordinates of the point would be (0, 5).

Answer:

$140.74

Step-by-step explanation:

Assuming this is a decaying exponential function, we can find a model for the depreciation in the form of v = a(b^t)

At t = 0, we get 5000 = a(b^0), which gives us a = 5000

At t = 1, we get 4000 = 5000b, such that b = 4/5

Now that our function is defined as v = 5000(4/5)^t, we can plug in t = 16 to solve for the value of the piano.

v = 5000(4/5)^16, which is approximately $140.74.

The integers are 14 and 16.

Let the integers be represented by x and x+2.

It was stated that the consecutive even integers such that 6 times the smaller integer is 36 more than 3 times the larger integer.

This will be:

6(x) = 3(x + 2) + 36

6x = 3x + 6 + 36

6x = 3x + 42

6x - 3x = 32

3x = 42

The probability that among those selected the second smallest in 2020 is 1/3

In this question, we have been given six distinct integers are selected at random from 2018, 2019, 2020, . . . , 2027

We need to find the probability that among those selected the second smallest in 2020.

Here, total integers are: 10

The total number of ways to choose six distinct integers :

10C6

= 10!/6!(10 - 6)!

= 210

Assume 2020 is the second-lowest number.

There are 5 numbers left to choose, 4 of which must be greater than 2020.

This is equivalent to choosing 4 numbers from the seven numbers larger than 2020, and 1 number from the two numbers less than 2020

using combination formula,

7C4 * 2C1

= 35 * 2

= 70

So, the probability would be,

P = 70/210

P = 1/3
