Answer:

$f^{-1} (x)=9x+18$

Step-by-step explanation:

Assuming $f(x)=\frac{1}{9} x-2$

What we have to do is replace f(x) with y, swap the locations of x and y, and then solve for y.

$y= \frac{1}{9} x-2\\\\x=\frac{1}{9}y-2\\ \\x+2=\frac{1}{9}y\\\\y=9x+18\\\\f^{-1} (x)=9x+18$

You drop a pencil out of window that is 20ft above the ground. Use the formula V^2=64s, where V is speed and s is the distance f

gizmo_the_mogwai [7]

First you substitute in the values so you have
V^2=(64)20
then you just simplify it
V^2=1280
V=the square root of 1280
V= about 35.7770876
or
V=the square root of 256 times <span>the square root of 5
V=16 times </span><span>the square root of 5

also V would typically be called velocity. it's very similar to speed but it is just easier to remember because it starts with a V</span>
