the answer is suppose to look like this y = .# + .#
examples

y = -0.25 x + 1.03
y = -0.48 x + 1.12
y = -0.68 x + 1.24
y = -0.84 x + 1.38
y = -0.95 x + 1.50
or none of these

Is fuel (gasoline) conductive?
why dosen't a (automotive) fuel pump cause an explosion inside an autos fuel tank when voltage is applied?
the pump is located in the tank and submerged in the fuel some of the time(full tank), some of the time it is exposed to the fumes in the tank when the tank is low. Also the wires that go to the pump are exposed to the fuel, meaning the fuel is in contact with the terminals of the pump. The wires are not sealed from the fuel.
The pump is not always submerged in the fuel as when the car is low on fuel !! And "if" the fuel is conductive, why dosen't it short out the EXPOSED terminal ends on the pump, and cause the pump to short circuit???
the voltage going to the pump is at least 12 volts dc with about 5 amps.

I'm on 0.25 mcg. I've been on it a couple of weeks and I do feel quite a bit better mentally and physically already, but my appetite has increased a whole lot. I thought levothyroxine was supposed to decrease the appetite a little bit. I'm confused here.

.. of course it seems to be a known fact that the speed of light c~299.000 m/sec is the ultimate speed limit of things.

Now regarding the outcome of experiments like the double-slit experiment which was like:
'obviously the photon knows which slit is open, and where the detector is'.. i would like to ask wether it's a little different.
Lets assume something CAN travel >c lets disregard and leave open WHERE and HOW .. but ...
Wouldn't be something travelling at >c would make us believe we observe something traveling at a finite speed in the opposite direction ?
Possibly making us believe it acts like knowing the setup, cause it already passed through in the opposite direction for example ?

Consider the ordinary differential equation :- dy/dx=2xy with y=1 and x=1?
try to obtain estimates of the value of y when x = 1.6 by using The fourth-order Runge-Kutta method :

Yn+1 = Yn + 1/6(k1+ 2K2+2k3=k4)

Where

k1= hf(Xn,Yn)
k2= hf(Xn+1/2h ,Yn+ 1/2K1)
k3= hf(Xn+1/2h ,Yn+ 1/2K2)
k4= hf(Xn+h ,Yn+K3)
