Q is proportional to the product of the squares of M and u and inversely proportional to the cube of a.

Question

Write an equation that expresses the statement. (Use k as the constant of proportionality.)

Answer 1

Hi Emily,

Proportional means that as one quantity grows, the other grows, too.

Inversely proportional means that as one quantity grows, the other shrinks.

Taken one at a time:

Q = k/a³

Q = kM²u²

Then together: Q = (kM²u²)/(a³)
