Which description compares the vertical asymptote(s) of Function A and Function B correctly?
r-ruslan [8.4K]
Function A:  f(x)=\frac{1}{x}+4.  Vertical asymptotes are in the form x=, and they are a vertical line that the function approaches but never hits.  They can be easily found by looking for values of <em>x</em> that can not be graphed.  In this case, <em>x</em> cannot equal 0, as we cannot divide by 0.  Therefore <em>x</em>=0 is a vertical asymptote for this function.  The horizontal asymptote is in the form <em>y</em>=, and is a horizontal line that the function approaches but never hits.  It can be found by finding the limit of the function.  In this case, as <em>x</em> increases, 1/<em>x</em> gets closer and closer to 0.  As that part of the function gets closer to 0, the overall function gets closer to 0+4 or 4.  Thus y=4 would be the horizontal asymptote for function A.
Function B:  From the graph we can see that the function approaches the line x=2 but never hits.  This is the vertical asymptote.  We can also see from the graph that the function approaches the line x=1 but never hits.  This is the horizontal asymptote.

Resolve into factor..<br>Please solve this by step by step ... ​
lys-0071 [83]

Answer:

9x^4 + 2x²y² + y^4

Arrange the terms

9x^4  + y^4 + 2x²y²

making the first two terms into a² + b²

(3x²)² + (y²)²   + 2x²y²

use the formula of a² + b² = (a+b)² - 2ab

(3x² + y²)²  - 2.3x².y²   + 2x²y²

(3x² + y²)²  - 6x²y² + 2x²y²

(3x² + y²)² - 4x²y²

(3x² + y²)² - (2xy)²

use the formula a² - b²

(3x² + 2xy + y²) (3x² - 2xy + y²)

OB is the bisector of AD and EC. . EO = 2x – 20 and OC = 70 – x. Solve for x.
mixas84 [53]
<span>We know that OB bisects EC where they intersect would be at point O, 
so the two lengths EO and OC must be equal. 

2x - 20 = 70 - x 

</span>[adding x + 20 to each side] 

2x - 20 + x + 20 = 70 - x + x + 20

[simplifying]

<span>3x = 90 

</span>[dividing each side by 3]
<span>
x = 30 would be the answer</span>

Answer:

b

Step-by-step explanation:

It is asking for the value of the green box.

The distance formula is given too.

Q = (0,-a)

P = (b, -c)

d = √(b - 0)² + (-c - (-a))²

d = √b² + (-c + a)²
