$3,708.33 is withheld monthly for state taxes.
Some states have a graduated income tax that involves a different tax rate for each of several levels of income. The tax rate increases as income increases.
Tax Withheld per Pay Period = Annual Tax Withheld/ Number of Pay Periods per Year
Here, we are given that Kerry McCarthy is a news traffic reporter with an annual gross pay of $44,500.
Thus, the Annual Tax Withheld = $44,500.
He is paid on a monthly basis ⇒ Number of Pay Periods per Year = 12
Hence, we get-
Tax Withheld per Pay Period = 44,500/ 12
= 3,708.33
Thus $3,708.33 is withheld monthly for state taxes.

write a polynomial function of least degree with integral coefficients that has the given zeros. -1, 3+3i
The least degree polynomial function with integral coefficients and the given zeros, -1, 3+3i is f(x) = x³ + x².
What do we mean by polynomial function?A polynomial function is one that involves only non-negative integer powers or positive integer exponents of a variable in an equation such as the quadratic equation, cubic equation, and so on. For example, 2x+5 is a polynomial with an exponent of one.So, given zeroes are -1, 3+3i.
We got: x = -1Then, x + 1 = 0.Hence, one factor of the polynomial function is (x+1).Similarly,
We have: 3+3iRewrite as: x = 3 + √-9Square both the sides: x² = 9 - 9So, the other factor is x².So, the polynomial has the function: (x+1)x²

A water molecule has a mass
of 3 x 10-29 kg. A bottle
contains 1.7x 1028 molecules of water. Calculate the mass
of water in the bottle.
Answer: 5.1 x 10⁻¹ kg
To find the mass of water in the bottle, we can multiply the mass of one molecule by the number of molecules.
Dimensional AnalysisBy using dimensional analysis, or by cancelling out units, we can figure out what to multiply or divide. Dimensional analysis uses fractions written with units. Dividing the same unit cancels out units we don't need.
To solve:
Figure out what units we need in the answer.Write the fractions using given information from the question.Put the fractions in an equation.Cancel out units to solve.Units we need in the answerWe are looking for the mass of H₂O in the bottle.
The units we need in the answer are: [tex]\displaystyle{ \frac{kg}{bottle} }[/tex]
Write fractions with given informationThe question tells us:
the mass of one H₂O molecule is 3 x 10⁻²⁹ kg: [tex]\displaystyle{ \frac{(3 * 10^{-29}\ kg)}{1\ H_{2}O}}[/tex]the bottle has 1.7 x 10²⁸ molecules of H₂O: [tex]\displaystyle{ \frac{(1.7*10^{28}\ H_{2}O)}{1\ bottle}}[/tex]Write an equationOur equation puts the fractions in an equation, making them multiply to get the units we need.
[tex]\displaystyle{ \frac{(3 * 10^{-29}\ kg)}{1\ H_{2}O} \ *\ \frac{(1.7*10^{28}\ H_{2}O)}{1\ bottle}}\ =\ \frac{kg}{bottle}[/tex]
Why is this equation correct?
Remember that dividing the same unit will cancel them out. In the equation, we have H₂O in a numerator and H₂O in a denominator. So, H₂O will cancel out. In the end, we will only have kg in the numerator and bottle in the denominator.
Cancel out units to solveTake the equation we wrote. Now that we know our equation gives us the right units, we only need the front part.
[tex]\displaystyle{ \frac{(3 * 10^{-29}\ kg)}{1\ H_{2}O} \ *\ \frac{(1.7*10^{28}\ H_{2}O)}{1\ bottle}}[/tex]
Cancel out H₂O:
[tex]=\displaystyle{ \frac{(3 * 10^{-29}\ kg)}{1} \ *\ \frac{(1.7*10^{28})}{1\ bottle}}[/tex]
Simplify the equation:
[tex]=\displaystyle{ \frac{(3 * 10^{-29})*(1.7*10^{28})\ kg}{1\ bottle}[/tex]
[tex]=\displaystyle{ \frac{3 * 10^{-29}*1.7*10^{28}\ kg}{1\ bottle}[/tex]
Use exponent rules to multiply 10⁻²⁹ with 10²⁸:
[tex]=\displaystyle{ \frac{3 *1.7*10^{28-29}\ kg}{1\ bottle}[/tex]

Explain how negative powers of 10 can be
helpful when writing and comparing small
numbers.
Negative powers of 10 helpful when writing and comparing small numbers.
Small numbers (numbers between 0 and 1) are written with a negative power of ten. The specific power of 10 indicates just how big or how small the number is. You can compare two numbers written in scientific notation by looking at their powers of 10. The number with the greater power of 10 will be the greater number.
When comparing small numbers, write these numbers in scientific notation (only one non-xero digit must be before point) and then
if the powers of 10 are the same in compared numbers are the same, just compare the numbers which are multiplied by these powers of 10. For example, 3.6× 10∧-6 is greater than 2.6× 10∧-6 because powers are the same (-6) and 3.6 is greater than 2.6if the powers are different, then the smaller is power, the smaller is number (number with the smaller negative power has more places after decimal point). For example,3.6× 10∧-6 is greater than 2.6× 10∧-7 because -6 > -7.10 to the power of negative 7 is equal to 0.0000001.For example- 0.00003450000

Determine whether the sequence converges or diverges. How do you know if it converges or diverges? If it converges, give the limit. (7)
The sequence converges as the degree of the numerator and denominator are the same.
How to find the limit of a rational equation
In this question we have the case of a rational equation representing a sequence, of which we must determine if the sequences converges and diverges. An useful form to prove the convergence of rational equations is using limit and algebra properties:
(5 · n - 1) / (n + 1)
[(5 · n - 1) / (n + 1)] · 1
[(5 · n - 1) / (n + 1)] · (n / n)
[(5 · n - 1) · n] / [(n + 1) · n]
[(5 · n - 1) / n] / [(n + 1) / n]
(5 - 1 / n) / (1 + 1 / n)
As n → + ∞, then 1 / n → 0 and the limit of (5 · n - 1) / (n + 1) is 5. Thus, the sequence converges as the degree of the numerator and denominator are the same.

The difference of the squares of two positive consecutive even integers is 84. Find the integers. Use the fact that, if x represents an even integer, then x + 2 represents the next consecutive even integer.
Answer:
The integers are 20 and 22
Step-by-step explanation:
Let the first even integer be x . Then the next consecutive even integer
= x + 2
The relationship between these two integers is the difference of the squares = 84
This means
(x + 2)² - x² = 84
Use the relationship a² - b² = (a + b) (a -b)
Here a = x + 2 and b = x
So
a + b = (x + 2 ) + x = x + 2 + x = x + x + 2 = 2x + 2
a - b = (x + 2) - x = x + 2 - x = x -x + 2 = 2
Therefore
(a + b)(a - b) in terms of x is
(2x + 2) x 2 = 4x + 4
We know this is 84
So 4x + 4 = 84
Subtract 4 on both sides:
4x = 84 -4
4x = 80
x = 20
So the next consecutive even integer = 22
The integers are 20 and 22

The option yes, d = -2 is correct
The arithmetic sequence or progression is a sequence of numbers such that the difference between the consecutive terms is constant.
The formula of an arithmetic sequence is
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1)d
Here the sequence is 18, 16, 14, 12, 10...... which is in arithmetic sequence as there is a common difference between them.
Now we have to find the common difference between the two consecutive terms of the series,
common difference (d) = 16- 18 = 14 - 16 = -2
Therefore the series is an arithmetic sequence and the common difference between them is -2.

The container that holds the water for the football team is 2/5 full. After pouring in 6 gallons of water, it’s 7/10 full. How many gallons can the container hold
Answer:
20
Step-by-step explanation:
We need to determine what fraction of the container 6 gallons is. We know the difference between 2/5 and 7/10 is 6 gallons, so all we have to do is solve for 7/10 - 2/5. The common denominator is 10, as both 5 and 10 are factors of 10. 10/5 is 2, so we multiply the numerator of 2/5 by 2.
7/10 - 4/10 = 3/10
We now know that 6 gallons is 3/10 of the container. Now we solve.
10/3 = 3 1/3
So:
6 x 3 1/3 = 20
Answer:
20 gallons.-
Step-by-step explanation:
Let x be the number of gallons that the container holds.
The we have the equation
2/5 x + 6 = 7/10 x
Multiply through be 10
4x + 60 = 7x
3x = 60
x = 20.

the base is of this pyramid is a square. how do you find the area of a square.
Answer:
If you're just looking for the area of the square, then it's 49m. If you want the surface area of the whole pyramid, it's 189.
Step-by-step explanation:
For just the square, it's easy: Multiply the side lengths. 7x7 is 49.
For the surface area, find the area of the square (49) and the four triangles. To find the areas of the triangles, multiply the base (bottom, here it's the side length of the square) by the height (in this case 10m) and divide by 2. 7x10=70 and 70/2=35. Now since there are 4 triangles, multiply that by 4. 35x4=140, and now add the area of the square; 140+49=189. I don't think you wanted the surface area though, but I hope this helps!
