Question

The amount of a certain bacteria y in a Petri dish grows accused riding to the equation dy/dt=Ky, where k is a constant and t is measured in hours. If the amount of bacteria triples in 10 hours, then k=?

Answer 1

3/10
Change in bectiria over time is ky,lets say after 10 hrs bectiria tripels so itbecomes 3y
dy/dt=3/10 
3y/10=ky
K=3/10

Hope this is right
