Are you looking for distance or displacement?

Logorithm

It is it's own formula, if you were to use the "LOG" button, the calculator would input the standardized formula and give you an output.

I agree i believe the answer is J

Okay so this is a simple multiplication problem (for the most part). 

If a runner is running at 2.4 m/s what is the distance it will travel in lets say 2 minutes.    <----Second time interval

Well first you'd want to convert those minutes into seconds. So there are 120 seconds in 2 minutes.

Now into the multiplication,             if for every second the runner is running 2.4 meters then you would multpily 2.4 by however many seconds

(2.4) x 120 = 288 meters 

To add on to Cavallin ^^^

Theres also this thing called the double negative rule where if you have 

(-2) - (-7)                If you take away the parenthesis you see two negative symbols right next to each other

If ever you see that    -2 - -7         the double negative turns into a positive so your new problem would be

-2 +7 = 5

Okay so i think what your asking  is

one and three fifths times a negative three fourths?

Thats the Quadratic Formula, you plug in the appropriate numbers according to the letts

(Example:

4x² + 5x +7

(a)     (b)  (c)
