After tax and voluntary deduction, Cheryl's net pay is $1,667.50.
Given that, Cheryl's gross pay= $2,875.
Tax deduction=30%, and Voluntary deductions=12%.
We need to calculate how much was Cheryl's net pay.
What is the difference between gross pay and net pay?
Employees earn gross compensation before taxes, benefits, and other payroll deductions are deducted from their pay. Net pay, often known as take-home pay, is the amount left over after all withholdings have been deducted.
We know that Net pay = Gross pay×(100% - 30% - 12%) ......................... (1)
Substituting for gross pay in equation (1), we get
Net pay = $2,875×(100% - 30% - 12%)
Net pay = $2,875×58%
Net pay = $1,667.50
Hence, after tax and voluntary deduction, Cheryl's net pay is $1,667.50.

3. continuous; 0 ≤ x ≤ 12; 0 ≤ y ≤ 6
4. discrete; domain: {2, 4, 6, 8}; range: {10, 18, 26, 34}
Step-by-step explanation:
You don't need to "try everything." You only need to learn the vocabulary.
3.A) A continuous function is one whose graph can be drawn without lifting your pencil. The graph shown is one continuous downward sloping line between the two marked points (0, 6) and (12, 0). The function is continuous.
B) The domain of a function is the horizontal extent of its graph, the set of input values for which output values are defined. This graph extends from x=0 to x=12, so the domain is ...
0 ≤ x ≤ 12
C) The range of a function is the vertical extent of its graph, the set of output values it produces. This graph extends from y=0 to y=6, so the range is ...
0 ≤ y ≤ 6
4.A) The problem statement tells you the domain is a particular set of positive numbers. If you were to graph it, you would have to lift your pencil between plots of the specific points listed. The function is discrete.
B) The problem statement tells you the domain is a particular set of numbers. It is probably easiest to simply list them:
{2, 4, 6, 8} . . . . . . . . domain; positive even numbers less than 10
C) The expression for y tells you how to find the output values associated with these input values. The list of output values is the range of the function.
y = 4x +2 = 4(2, 4, 6, 8} +2 = (8, 16, 24, 32} +2 = {10, 18, 26, 34}
The range is ...

a. the area of the shaded region is 8.1879 cm²
b. the height of the triangle is 10.0708 cm
Since the shaded region is a segment, we need to find the area of the shaded region.
How to find the area of the shaded region?Area of the shaded region A = area of sector, A' - area of triangle, A"
The area of sectorArea of sector, A' = Ф/360 × πr² where
Ф = angle of sector = 46° andr = radius of circle = 14 cmSo, substituting the values of the variables into the equation, we have
A' = Ф/360 × πr²
= 46/360 × π(14 cm)²
= 46/360 × 196πcm²
= 9016π/360 cm²
= 25.0444π cm²
A' = 78.6793 cm²
So, the area of the sector is 78.6793 cm²
The Area of triangleArea of triangle, A" = 1/2r²sinФ where
r = radius of circle = 14 cm andФ = angle of sector = 46°So, substituting the values of the variables into the equation, we have
A" = 1/2r²sinФ
= 1/2 × (14 cm)²× sin46°
= 1/2 × 196 cm² × 0.7193
= 98 cm² × 0.7193
A" = 70.4914 cm²
a. The Area of the shaded regionThe area of the shaded region A = area of sector A' - area of triangle, A"
= 78.6793 cm² - 70.4914 cm²
= 8.1879 cm²

Maci and 2 appointments and Logan had 3 appointments.
How many appointments did Maci and Logan have?The linear equation that represents the total amount earned by Maci is:
Total amount earned = (amount per appointment x number of appointments) + tips
$170 = ($60 x a) + $50
$170 = $60a + $50
$170 - $50 = $60a
$120 = $60a
a = $120 / $60
a = 2
The linear equation that represents the total amount earned by Logan is:
Profit = total revenue - total cost
Profit = (fee per appointment x number of appointments) + amount received in tips - (rental fee x number of appointments)
$235 = ($75 x a) + $40 - ($10 x a)

Which has a greater effect on the volume-changing the radius by a given amount or changing the height by the same amount? Why?
Answer: Changing the radius of an object by a given amount has a greater effect on the volume than changing the height by the same amount. The volume of a cylinder is given by the formula V = πr²h, where V is the volume, r is the radius, and h is the height. If we change the radius by a given amount, say x, the new radius would be r+x. Hence, the new volume would be V' = π(r+x)²h = π(r²+2rx+x²)h = V + 2πrxh + πx²h. We can see that the volume change equals 2πrxh + πx²h. The first term is proportional to both the radius and the height, whereas the second term is proportional to the square of the radius and the height. Assuming that the height change is also x, the new volume would be V'' = πr²(h+x) = V + πr²x. We can see that the volume change is proportional to the radius squared and the change in height. Therefore, changing the radius by a given amount has a greater effect on the volume than changing the height by the same amount.

"What is the rest wavelength of an emission line observed at 2148 nanometers in a galaxy 100
Megaparsecs away from the Milky Way? Your answer should be significant to four digits."
The rest wavelength of the emission line observed at 2148 nanometers in the galaxy 100 million light-years away is approximately 2103 nanometers.
The rest wavelength of an emission line can be determined by applying the concept of redshift, which is a phenomenon observed in astrophysics where light from distant objects is shifted towards longer wavelengths due to the expansion of the universe.
In this case, the emission line is observed at 2148 nanometers (or 2.148 micrometers) in a galaxy located 100 million light-years away. To calculate the rest wavelength, we need to consider the redshift factor. Redshift, denoted by z, is defined as the observed wavelength divided by the rest wavelength minus 1.
Given that the observed wavelength is 2.148 micrometers and the galaxy is located 100 million light-years away, we need to convert the distance into a redshift factor using the cosmological relationship between redshift and distance. Assuming a standard cosmological model, we can use the Hubble constant to estimate the redshift.
The Hubble constant represents the rate at which the universe is expanding. Taking a typical value of the Hubble constant as 70 kilometers per second per megaparsec, we find that the redshift factor, z, is approximately 0.021.
To determine the rest wavelength, we rearrange the redshift equation as \((observed wavelength) = (1 + z) \times (rest wavelength)\). Substituting the values, we get \((2.148 micrometers) = (1 + 0.021) \times (rest wavelength).\)
Simplifying the equation, we find the rest wavelength to be approximately 2.103 micrometers or 2103 nanometers.
