Thanks Chris but I am a little confused.

Write an equation for a rational function with: Vertical asymptotes at x = 4 and x = 6 x intercepts at x = -4 and x = 2 Horizontal asymptote at y = 9

Since the roots are x=-4 and x=2  The numerator must contain  (x+4)(x-2)

And since  x=4 and x=6 are  aymptotes the denominator must contain     (x-4)(x-6)

BUT i don't understand the logic behind the horizontal asymptote at y=9     

**I have added this to our reference material thread so if it is expanded upon that would be really good  

They are on the bottom row of your keyboard (assuming you are using a keyboard)

If you go to insert on the ribbon it has a drop down menu and one of those is special characters.  There are many special characters in there :)

Quadrilateral ABCD is inscribed in a circle. m  A is 64°, m  B is (6x + 4)°, and m  C is (9x - 1)°. What is m  D?

C=180-A=180-64=116

so

9x-1=116

9x=117

x=13

B=2x+4=6*13+4=82

D=180-82=98 degrees 

Thanks Chris

This is a great question for middle and upper high school students to attempt. 

That calculator output is incorrect.

-(50x)^2=-2500x^2    !!!

(-50x)^2 = +2500x^2

But the actual question is   -50x^2     and this cannot be simplified.

Work through this and then maybe you will be able to do it yourself :)

What are my monthly payments on a car loan if I want to borrow $24,000.00 at 1.74% interest over 60 months?   I assume that is 1.74% per month.

i=0.0174

n=60

PV(present value) = $24000

Find C

Can you do the substitution yourself ?   Give it a go :)

You need to include the address of the question that you are refering to.

You can copy it and paste it onto your post.

We are very happy to answer follow up queries but you need to make it easy for us to find the actual question.

OR

If you write you question in a new post on the original thread, we will almost definitely see it and answer you. :)

$$\\tan^2x=\frac{4}{8}\\\\
tan^2x=\frac{1}{2}\\\\
tanx=\frac{1}{\sqrt2}\\\\
x=45\pm 180k\;\;degrees \quad k\in Z \qquad $(k is in the set of integers)$$$
