Part A: Using the method of your choice, demonstrate how to calculate the amount of taxes owed on a taxable income of $31,000. Show all work. (4 points)
Part B: Using the taxes owed from part A, determine the effective tax rate. Show all work. (4 points)
Part C: Compare the piecewise function to the marginal tax rate chart. How is the marginal tax rate chart represented in the piecewise function? (2 points)
Answer:
Part A: $3,415.50
B: 11.34%
Step-by-step explanation:
Part A: $31,000 is within the values 10,276≤x≤41,175, so use f(x)=0.12x-205.50
Part B: For the effective tax rate, divide the amount in part A by the taxable income
Part C: Compare both the taxable income and the effective tax rate to the income domains given and the % multiplier. This one is mostly about how you describe the situation, so I'll leave that up to you.
To calculate the taxes owed on a taxable income of $31,000, we use the appropriate equation for the tax bracket it falls into and substitute the value of x. The effective tax rate is calculated by dividing the amount of taxes owed by the taxable income and multiplying by 100. The piecewise function represents the marginal tax rate chart by using different equations for each tax bracket.
Explanation:Part A:
To calculate the amount of taxes owed on a taxable income of $31,000, we need to determine which tax bracket it falls into. Since $31,000 is greater than $10,275 but less than $41,175, it falls into tax bracket 2. To find the amount of taxes owed, we use the equation for tax bracket 2: f(x) = 0.12x - 205.50. Plugging in $31,000 for x, we get:
f(x) = 0.12 * 31000 - 205.50 = $3,574.50
Therefore, the amount of taxes owed on a taxable income of $31,000 is $3,574.50.
Part B:
To determine the effective tax rate, we divide the amount of taxes owed by the taxable income. Using the result from Part A (taxes owed = $3,574.50) and the taxable income of $31,000, we have:
Effective tax rate = (taxes owed / taxable income) * 100 = (3,574.50 / 31,000) * 100 ≈ 11.52%
Therefore, the effective tax rate on a taxable income of $31,000 is approximately 11.52%.
Part C:
The piecewise function represents the amount of taxes owed as a function of the taxable income. Each part of the function corresponds to a different tax bracket, with the equation for that tax bracket. The marginal tax rate chart is represented in the piecewise function by the different equations for each tax bracket. For example, the equation in part 1 of the function (f(x) = 0.10x) corresponds to the 10% marginal tax rate for the tax bracket $0-$10,275.

cesar gasto el 15% de sus ahorros en un celular por lo que ahora le queda 2.125 dolares ahorrados ¿cuanto dinero tenia inicialmente cesar?
Cesar initially had $2,500 in savings.
Let's solve the problem step by step.
Let's assume that the initial amount of money Cesar had is represented by "x" dollars.
According to the problem, Cesar spent 15% of his savings on a cellphone, which means he has 85% of his initial savings left. We can represent this mathematically as:
0.85x = 2,125
To find the initial amount of money Cesar had, we need to solve for x. We can do this by dividing both sides of the equation by 0.85:
x = 2,125 / 0.85
Calculating this value:
x = 2,500
Cesar initially had $2,500 in savings.
Please note that the calculations are done assuming a straightforward interpretation of the problem. If there are additional factors or context that could affect the interpretation, it's important to consider them in order to arrive at an accurate answer.

Find the dimensions of the closed right circular cylindrical can of smallest surface area whose volume is 2picm^3
Answer and Step-by-step explanation:
Solution:
Given:
V = 2π cm3
We know that:
2π = πr2h
2π / πr2 = h
Which gives: h = 2 / r2
Minimize surface area = 2πrh + 2πr2
S = 2πrh + 2πr2
Put h = 2/ r2 in surface area, we get:
S = 2πr (2/ r2 ) + 2πr2
S = 4 π / r + 2πr2
Therefore, s(r) = 4 π / r + 2πr2
Differentiate concerning r, we have
S’(r) = -4π / r2 + 4πr
Again differentiate concerning r, we have:
S”(r) = 2 x 4 π/ r3 + 4π
For s’(r) = 0
0 = -4π / r2 + 4πr
-4π + 4πr3 = 0
r3 = 1
r = 1 cm
and s”(1) > 0 at r = 1 is point of minima.
So h = 2 π / π x1 x1
= 2cm
Therefore minimum surface area the can should have a radius of 1cm and height of 2cm.
What is (f/g)(x)?
f(x) = -x
g(x) = -5x + 2
Write your answer as a polynomial or a rational function in simplest form.
The rational function in the simplest form of (f/g)(x) is x / 5x - 2.
How to solve functions?Composite functions are when the output of one function is used as the input of another. A typical example of a composite function is (f/g)(x).
Therefore, let's solve the rational function in the simplest form.
Hence,
f(x) = -x
g(x) = -5x + 2
(f/g)(x) = f(x) / g(x)
Therefore,
(f/g)(x) = - x / -5x + 2
Hence,
(f/g)(x) = - x / - (5x - 2)
Finally,
(f/g)(x) = x / 5x - 2

Can you slove it?
Answer:

First, distribute the -3:
\(y-6y+21=76\)
Combine like terms on the left:
\(-5y+21=76\)
Subtract 21 from both sides:
\(-5y=55\)
Divide both sides by -5:
\(y=-11\)

A bottle of water has a diameter of 3 inches and a height of 8 inches, and a mass of 1250 g. What is the volume and density?
The volume of the bottle is 56.52 cubic inches, and the density is 22.12 g/in³.
What is the volume and density of the bootle water?The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 ).
Density is expressed mathematically as;
p = m / v
Where m is mass and v is volume.
Given that:
Diameter = 3 in
Radius r = diameter/2 = 3/2 = 1.5 in
Height h = 8 in
Mass m = 1250 g
Find the volume:
V = π × r² × h
V = 3.14 × (1.5 in )² × 8in
V = 56.52 in³
Find the density:
p = m / v
p = 1250g / 56.52 in³
p = 22.12 g/in³

The height of the tree is equal to 210 ft to the nearest foot using the sine rule.
What is the sine ruleThe sine rule is a relationship between the size of an angle in a triangle and the opposing side.
angle opposite of the tree = 56 - 26 = 30
angle opposite of the shadow = 180 - 90 - 56= 34

How to determine the count of numbers in the list a, a+1, a+2.... b?The list of numbers is given as:
a, a+1, a+2.... b
From the above list, we can see that the numbers are consecutive numbers.
This means that, the count of numbers in the list is
Count = Highest - Least + 1

Highest = b
Least = a

e) f(h(x)) = __x^2+__x+__
f) f(g(x)) =__x^3+__x^2+__x+__
Answer:
Step-by-step explanation:
the concepts are confusing of what a function is. f(x) seems mysterious , huh
it's just a way to give a label to some set of terms. Just think of it as a name of a person, but in a generic sense, like hey "guy" or hey "gal" you can address many people that way. f(x) is doing that same thing addressing by a name, a set of math terms.
a)
in a) we are addressing the g(x) function and we are also sending that function the number -2 as an input. so find the g(x) function and put in (-2) everywhere that there is an "x" , so
g(x)=\(x^{3}\)-3\(x^{2}\)+2x + 11
g(-2) = \((-2)^{3}\)-3\((-2)^{2}\)+2(-2)+11
g(-2) = -8 -3(4) - 4 +11
g(-2) = -8 -12 -4 + 11
g(-2) = -24 + 11
g(-2) = -13
b)
h(-1) find the h(x) function and input a negative 1 where ever there is an x
h(x) =
h(-1) = \((-1)^{2}\) - 3
h(-1) = 1 - 3
h(-1) = -2
c)
for c) just combine like terms of the two given functions
g(x) - h(x) = \(x^{3}\)-3\(x^{2}\)+2x + 11 - (\(x^{2}\) - 3)
g(x) - h(x) = \(x^{3}\)-3\(x^{2}\)+2x + 11 - \(x^{2}\) + 3
g(x) - h(x) = \(x^{3}\)-4\(x^{2}\)+2x + 14
d)
-2f(x) - h(x) = -2(3x + 2) - (\(x^{2}\) - 3)
-2f(x) - h(x) = -6x - 4 - \(x^{2}\) + 3
-2f(x) - h(x) = -6x - 1 - \(x^{2}\)
-2f(x) - h(x) = - \(x^{2}\) - 6x - 1
e)
f(h(x)) this gets a bit more confusing b/c it's a composition of functions, that's just a fancy way of saying the functions are nested. one inside the other.
f(x) = 3x + 2
h(x) = \(x^{2}\) - 3
plug h(x) in to f(x) where ever there is an x in f(x) , luckily there is only one x in f(x) :)
f(h(x)) = 3(\(x^{2}\) - 3) + 2
f(h(x)) = 3\(x^{2}\) - 9 + 2
f(h(x)) = 3\(x^{2}\) - 7
f(h(x)) = 3\(x^{2}\) + 0x + (-7)
f)
f(x) = 3x + 2
g(x) = \(x^{3}\)-3\(x^{2}\)+2x + 11
f(g(x)) = 3(\(x^{3}\)-3\(x^{2}\)+2x + 11) + 2
f(g(x)) = 3\(x^{3}\)-9\(x^{2}\)+6x + 33 + 2
f(g(x)) = 3\(x^{3}\)-9\(x^{2}\)+6x + 35
