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,

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

Given an arc length of 6 pie and a radius of 2 find the measure of the central angle formed by the arc

Semmy [17]

Θ=3 $\pi$ radians

Step-by-step explanation:

Step 1:

Let the arc length (S) be 6 $\pi$ units

Radius of Arc(r) = 2 units

By the basic formula to find the central angle we have

$S=r*$ Θ

where, S= Arc length

r= Radius of arc

Θ = Central angle

Step 2:

From the formula to find Θ,

Θ = (S/r)

Θ = ( 6 $\pi$ ) / ( 2 )

Θ = 3 $\pi$ radians
