Determine the total annual FICA tax for an annual salary of $38,480. A. $294. 37 b. $717. 96 c. $2,385. 76 d. $2,943. 72.

matrenka [14]

Answer:
d. $2,943.72 is the total annual FICA tax for an annual salary of $38,480.

Explanation:
6.2% of the annual salary for the Social Security Tax, and 1.45% of the annual salary for the Medicare Tax. In total, FICA takes 7.65% of your annual salary as tax. $38,480 x 7.65% = $2,943.72.

Explain one development from the period of the atlantic revolutions that grounded ""social relations for the first time on the p

kupik [55]

Answer:

The answer is based off of the second paragraph of the 2nd source:

One development that was vital to the principle of equality was the American and French revolutionaries not conforming to traditional ways of life. For example, the revolutionaries expanded the “whole horizon of age.” This allowed more people to conform to their own agendas and not be suffocated by the “royal charisma.”

Explanation:

I am pretty sure this will give you the general idea of one of the actions took by revolutionaries to allow some form of equality. I would suggest putting this general statement into your own words to avoid any issues just in case my answer isn't sufficient :)

The graph of y=f(x) is shown above. Which of the following could be the graph of y=f′′(x)?.

AfilCa [17]

The true statement about the graph of f(x) is $f(x) = \frac 35x + 3$

The graph of f(x) is a straight line that passes through the points (-5,0) and (0,3).

Start by calculating the slope (m)

$m = \frac{y_2 - y_1}{x_2 -x_1}$

So, we have:

$m = \frac{3-0}{0--5}$

Simplify

$m = \frac{3}{5}$

The equation of the line is then calculated as:

$y = m(x -x_1) + y_1$

This gives

$y = \frac 35(x -0) + 3$

Open bracket

$y = \frac 35x + 3$

Express y as a function of x

$f(x) = \frac 35x + 3$

Hence, the true statement about the graph of f(x) is $f(x) = \frac 35x + 3$

the graph of f is given. state the numbers at which f is not differentiable. (enter your answers as a comma-separated list.)

artcher [175]

The numbers at which f is not differentiable are; -1, and 2

The reason the above list of numbers at which f is not differentiable are correct are given as follows:

Question; Please find attached a graph that can be used to solve the question

A function is not differentiable at a point where the function has a discontinuity. That is a point on the graph were there is a break in the graph

Therefore, the given graph of f shows that the function is not differentiable at x = -1, the point where the graph has a discontinuity

A function is not differentiable at a point where the graph of the function has a kink or corner.

The graph of f has a kink at x = 2, therefore, the function is also not differentiable at x = 2
