Find the inverse of h(x)=(2x-4)/3

Agata [3.3K]

Answer:

The inverse of the h(x) is $h^{-1}(x)=\frac{3x}{2}+2$ Step-by-step explanation:

Given : Expression $h(x)=\frac{2x-4}{3}$

To find : The inverse of the expression ?

Solution :

Expression $h(x)=\frac{2x-4}{3}$

Let, h(x)=y then $y=\frac{2x-4}{3}$

For inverse we replace the value of x and y and find the value of y in terms of x.

Replace the value of x and y,

$x=\frac{2y-4}{3}$

Solve for y by cross multiply,

$3x=2y-4$

Adding 4 both side,

$3x+4=2y$

Dividing by 2 both side,

$\frac{3x+4}{2}=y$

Therefore, The inverse of the h(x) is $h^{-1}(x)=\frac{3x}{2}+2$

The formula for the volume of a sphere is v= 4/3 3.14rWhat is the formula solved for r?

prohojiy [21]

Answer:

$r = \frac{3}{4\pi}V$

Step-by-step explanation:

First, the formula for the volume of a sphere is:

$V = \frac{4}{3}\pi r^3$

$\frac{3}{4}V = \pi r^3$

$\frac{3}{4}V\frac{1}{\pi} = r^3$

$r^3 = \frac{3}{4\pi}V$

$r = \sqrt[\leftroot{-2}\uproot{2}3]{\frac{3}{4\pi}V}$
