maximum rms velocity formula
The usefulness is that this data allows you to understand how well students perform with their instruction, based on a standardized test. The limitation is that the scores don't account for different situations that may affect the results you receive.
Answer:
the formula to find slope is m=y1-y2/x1-x2
using this formula 8-6/8-(-4)
=2/8+4
=2/12 simplify
=1/6
(-30 km/h) -(45 km/h) = -75 km/h . . . . . east is positive here
The velocity changed 75 km/h to the west.
