I'm pretty sure should be shifting your transformation those two units to the right from the original function.
Moving right = subtracting
Moving left = adding

Density = (mass) / (volume), no matter how large or small the sample is.
We can't calculate the density, because you left out the number for the volume.
Also, you didn't tell us the unit for the mass of 180.
a). If the mass is 180 grams, then the density is
(180 gm) / (volume) .
b). No matter how many pieces you crush it into, and
no matter how large or small a piece is, its density is
the same. (I just wish we knew what the density really is.)
c). A piece may have 80 grams of mass. It doesn't "weigh" 80 grams.
Since the density of the whole rock is (180 gm) / (volume),
the density of any piece of it is (180 gm) / (volume).
Multiply each side by (volume): (Density) x (volume) = 180 gm
Divide each side by (density): Volume = (180 gm) / (density)
We can't calculate the volume of an 80-gm piece, because
we don't know the density. (That's because you left the volume
out of the question.)
Answer:
and 
Explanation:
The tub rotates at constant speed and the kinematic formula to describe the change in angular displacement (
), measured in radians, is:
Where:
- Steady angular speed, measured in radians per second.
- Time, measured in seconds.
If 
and 
, then:
The change in angular displacement, measured in revolutions, is given by the following expression:
Median plane - Sagittal plane through the midline of the body; divides the body or any of its parts into right and left halves.
