Answer:

You have vertical asymptotes on x=-4,-2

Step-by-step explanation:

This question is very simple. Since you have a denominator all you need to do is factor the bottom and find the zeros. When you factor the bottom of the equation you should get (x+4)(x+2). Now you have to set the bottom equal to zero to find the zeros. This means (x+4)=0 and (x+2)=0 So you get two answers x=-4 and x=-2 Therefore your two vertical asymptotes are on x-4,-2

Answer:

$x = \frac{ - 3b}{4} \: or \: b$

Step-by-step explanation:

$\frac{1}{b + x} = \frac{3b}{2 {x}^{2} } - \frac{1}{x}$

$= > \frac{1}{b + x} = \frac{3b - 2x}{2 {x}^{2} }$

$= > 2 {x}^{2} = (b + x)(3b - 2x)$

$= > 2 {x}^{2} = 3 {b}^{2} - 2bx + 3bx - 2 {x}^{2}$

$= > 2 {b}^{2} = 3 {b}^{2} + bx - 2 {x}^{2}$

$= > 3 {b}^{2} + bx - 4 {x}^{2} = 0$

$= > 3 {b}^{2} + 4bx - 3bx - 4 {x}^{2} = 0$

$= > b(3b + 4x) - x(3b + 4x) = 0$

$= > (3b + 4x)(b - x) = 0$

Hence,

$x = \frac{ - 3b}{4} \: or \: b$

The volume of a cylinder is 980 in. The height of the cylinder is 20 in. What is the radius of the cylinder? Express your answer

andreyandreev [35.5K]

R= $\sqrt{} \frac{V}{ \pi r}$

r= $\sqrt{} \frac{980}{ \pi *20}$

r≈3.95

Help please!!!!!!!!!!

Scorpion4ik [409]

Answer:

H. 1/9.

Step-by-step explanation:

The area of a circle is calculated by solving for π $r^2$ .

The smallest circle has an area of π $1^2$ = π * 1 = π.

The middle ring will then have an area of π $2^2$ - π = π * 4 - π = 4π - π = 3π.

The largest ring will then have an area of π $3^{2}$ - π $2^{2}$ = 9π - 4π = 5π.

5π + 3π + π = 9π

So, the probability of hitting the innermost circle will be π / 9π = 1 / 9.

Your answer is H. 1/9.

Hope this helps!
