How would i solve this equation for mass (m)?
f = (gm^2)/d^2

i know the answer is m = sqrt [(fd2)/g]
i'm just not sure how to get to that answer

(i had originally posted this in the physics section but hope i could get more out of this in the math section.)

Simple...

you have: 

You want to find m-->>>

1.)Isolate m



Leaving you with...

F*=

Keep isolating m-->>>





Square root to solve what just m is-->>>



=

That is how you solve for m...

Thus, your answer.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
