The equation for line r is
y=-1/3x+5
Perpendicular slope would be 3 and passes through (3,-6)
-6=3(3)+b
-6=9+b
-9. -9
-15=b
y=3x-15
Plug in the x value of the point to see if it’s true
y=3(3)-15
y=9-15
y=-6
So the equation is y=3x-15 so the answers is c
3x-y=15
-3x. -3x
-y=-3x+15
Divide everything by -1
y=3x-15

The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation R=pL/(pi)d^2 where p represents the resi

SashulF [63]

Answer:

The resistance approaches infinity

Step-by-step explanation:

We are given

The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation

$R=\frac{\rho L}{\pi (d)^2}$

where

p represents the resistivity of the wire’s material

L represents the length of the wire

d represents the diameter of the wire

now,

d approaches to 0

so, we can plug d=0 and find R

$R=\frac{\rho L}{\pi (0)^2}$

$R=\frac{\rho L}{0}$

$R=\infty$

So,

The resistance approaches infinity
