Part A
What is the 2010 federal income tax for a single person whose taxable income that year was 4000 dollars?
The function is
T(x)=0.1x
so
For x=4,000
substitute
T(x)=0.1*(4,000)
<h2>T(x)=$400</h2>
Part B
What is the 2010 federal income tax for a single person whose taxable income that year was 170000 dollars?
the function is
T(x)=0.28x-6,290.75
For x=170,000
substitute
T(x)=0.28*(170,000)-6,290.75
<h2>T(x)=$41,309.25</h2>
Part C
What is the taxable income for a single person whose 2010 federal income tax was 105000 dollars?
The function is
T(x)=0.28x-6,290.75
For T(x)=105,000
substitute
105,000=0.28x-6,290.75
solve for x
0.28x=105,000+6,290.75
0.28x=111,290.75
<h2>x=$397,466.96</h2><h2 />
You can figure out if two fractions are bigger by just cross multiplying the numerator and denominator of each fraction.

Multiply the 5 and 7, and then the 3 and 12. Be sure to start with the numerator of the first fraction.

5 * 7 = 35, 3 * 12 = 36
So

is bigger.
Answer:
infinitely many answers, any odd integer n times π/2
ex. π/2, 3π/2, 5π/2
Step-by-step explanation:
we know that cos (π/2) or cos(3π/2) is 0
if one factor is 0, the product is zero, so we will not care about csc(x).
x is any odd integer n times π/2
Answer:
There isn't a figure. But Acute angles are less than 90 degrees(they're small than an L). Remember it by saying "cute" things are small so acute
Step-by-step explanation:
Answer:

Step-by-step explanation:
<u>Firstly, we'll do prime factorization of these numbers.</u>
70 = 2 × 5 × 7
112 = 2 × 2 × 2 × 2 × 7
<u>So, The Greatest Common Factor can be written as:</u>
GCF = 2 × 7 <u>[Since Only one 2 and one 7 is common]</u>
<u></u>
Hope this helped!
