Answer:

Mr. Edelstein drove 48 miles per hour.

Step-by-step explanation:

12 miles for every 15 minutes

There are 60 minutes in an hour

Divide 60 by 15= 4

So you would multiply 12 by 4= 48

What is tan(x)-5=0<br> (With steps)

gizmo_the_mogwai [7]

$\tan x-5=0$
$\tan x=5$

Now before taking the inverse tangent of both sides, recall that

$\tan x=\tan(x\pm\pi)=\tan(x\pm2\pi)=\cdots=\tan(x\pm n\pi)$

where $n$ is any integer. This means that when taking the inverse tangent of $\tan x$ , instead of just $x$ , we would end up with

$\arctan(\tan x)=\arctan(\tan(x+n\pi))=x\pm n\pi$

So after doing so in the equation above, we're left with

$x\pm n\pi=\arctan5\implies x=\arctan5\pm n\pi$

As $n$ can be any integer, including negative integers, we can simply write

$x=\arctan5+n\pi,\,n\in\mathbb Z$
