Answers

Answer 1

Answer:

If you simplify the first expression, you will not get the second expression. In the first expression, the x2 terms have coefficients of 1 and –1 and, when combined, the result is 0. Also, the x terms have coefficients of 8 and –6 and, when combined, the result is 2. Finally, the constant from the first expression is not in the second expression.

Assume a tax rate of 6.2% on $128,400 for Social Security and 1.45% for Medicare. No one will reach the maximum for FICA. Complete the following payroll register. (Use the percentage method to calculate FIT for this weekly period

Marital status - m
Allowance claimed – 4
Gross pay - $,2800
FIT
Social Security
Medicare
Net pay

Answers

Answer:

FIT: $340.76 (see comment)OASDI: $173.60Medicare: $40.60Net Pay: $2245.04

Step-by-step explanation:

In addition to the information given in the problem statement, we need to know the applicable tax rates and allowance deductions. If we assume the tables we found (attachments 1 and 2) are the same as those in your text, the one additional fact needed is the gross pay to date. At the given wage rate, paychecks after the 44th week will have reduced FICA tax deductions.

Allowances: 4 × $79.80 = $319.20

Adjusted gross pay for FIT: $2800 -319.20 ≈ $2481 (rounded to nearest $)*

FIT: 0.22 × (2481 -1711) +171.36 = 0.22×2481 -205.06 = 340.76

Social Security & Medicare: 0.0765 × 2800 = 214.20

Net pay = $2800 -340.76 -214.20 = $2245.04

_____

* Comment on rounding

The IRS gives the option of rounding the pay or the tax, as long as it is consistently done. Here, the amount of tax on the unrounded gross pay would be 4 cents less: 340.72. The option of reducing the last digit of pay to zero is also offered. FIT on 2480 would be 340.54.

What are the domain and range of a function?

A function assigns the value of each element of one set to the other specific element of another set.

The domain is the set of values for which the given function is defined.The range is the set of all values which the given function can output.

From the given functions the function that has a range of (-∞, ∞) can be found by plotting the graph. Therefore, the parent function that has a range of (-∞, ∞) are:

B. a parent odd-degree power function

D. a parent odd-degree root function

G. a parent logarithmic function with a base greater than 1

H. a parent logarithmic function with a base between 0 and 1

Hence, the correct option is B, D, G, and H.

Answer:

k = 10

Step-by-step explanation:

(4k + 5) + (6k + 10) + 65 = 180

4k + 5 + 6k + 10 + 65 = 180

10k + 80 = 180

10k = 100

k = 10

A nursery has $60,000 of inventory in dogwood trees and red maple trees. The profit on a dogwood tree is 29% and the profit on a red maple tree is 17%. The profit for the entire stock is 20%. How much was invested in each type of tree?

Answers

Answer:

27g

Step-by-step explanation:

Ghjc

The invested amount dogwood tree is $15000 and on maple tree is $45000 as per linear equation.

What is a linear equation?

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."

Given, total invested amount is $60000.

Let, invested amount for dogwood trees is $x.

Therefore, invested amount for maple trees is ($60000 - x).

Now, the profit on a dogwood tree is 29% = 0.29.

The profit on a red maple tree is 17% = 0.17.

Again, the profit for the entire stock is 20%. = 0.20.

Therefore,

(x + x × 0.29) + [(60000 - x) + (60000 - x) × 0.17 = 60000 + 60000 × 0.20

⇒ 1.29x + 60000 - x + 10200 - 0.17x = 72000

⇒ 0.12x = 72000 - 60000 - 10200

⇒ 0.12 x = 1800

⇒ x = 15000

Therefore, invested amount  on dogwood tree is $15000.

Similarly, invested amount on maple tree is $(60000 - 15000) = $ 45000.
