If f(x)=x^2-1, what is the equation for f^-1(x)

Alekssandra [29.7K]

Let y = x^2 - 1
x^2 = y + 1

x = sqrt(y + 1)

so f^-1(x) = sqrt (x + 1) (answer)

Please help find volume of cone

Fudgin [204]

Answer:

5275.2 m³

Step-by-step explanation:

We need the radius first:

$\sqrt{l^2- h^2}$ = 12

Formula for volume = πr²*h/3

Volume = 3.14 * 144 * 35/3

Volume = 5275.2

PLEASE HELP!!!!! A satellite telescope has a parabolic dish. Satellite signals are collected at the focal point (focus) of the

-BARSIC- [3]

The dish illustrates operations on a parabola.

The depth of the parabolish dish is 160 feet.

The bowl is said to be a parabola.

So, we have:

$\mathbf{(x -h)^2 = 4p(y - k)}$

Where:

$\mathbf{Focus: p = 40}$

$\mathbf{Vertex:(h,k) = (0,0)}$

From the question, the diameter is 160 feet.

So, the radius (r) is:

$\mathbf{r = \frac{160}{2} = 80}$

So, the coordinate of the depth of the parabola would be:

$\mathbf{(x,y) = (60 + 100,y)}$

$\mathbf{(x,y) = (160,y)}$

Substitute these values in $\mathbf{(x -h)^2 = 4p(y - k)}$

So, we have:

$\mathbf{(160 - 0)^2 = 4 \times 40 \times (y -0)}$

$\mathbf{160^2 = 160y}$

Divide both sides by 160

$\mathbf{160 = y}$

Rewrite as:

$\mathbf{y = 160 }$

Hence, the depth of the parabolish dish is 160 feet.
