7. Find the angular velocity in rads per second for a pulley turning at 1800 rpm.

Aregression was run to determine if there is a relationship between hours of tv watched per day (x) and number of situps a person can do (y). the results of the regression were: y=ax+b a=-0.662 b=30.418 r2=0.703921 r=-0.839

What is the reflection image of (5,-3) across the line y = -x?

I’m still confused on how to work the percentages
