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 />

SOLVE x^4 − 15x^2 − 16 = 0 <br> What are the roots of the equation?
kakasveta [241]

Answer:

roots : 4, -4, i, -i

Step-by-step explanation:

This gets a bit tricky.

We have to substitude x^2 as u in this problem.

Now to rewrite x^4 − 15x^2 − 16 = 0 with u, we get

u^2 - 15u - 16 = 0

( u - 16) (u + 1)

U = 16

U = -1

<em>This is not the end of the problem. </em>

Now we have to substitute x^2 back to u.

x^2 = 16  --> we get the roots 4 and -4

x^2 = -1 --> we get the roots i and -i
