Fynjy0 [20]

Answer:

k=4

Step-by-step explanation:

-The constant of proportionality  is defined as the ratio between two directly proportional variables.

-Given that B=4f

#The constant of proportionality is calculated as:

- the equation can be written in the form y=kx,

where y varies directly with x and k is the constant of variation:

y=kx\\\\k=\frac{y}{x}\\\\\therefore  B=4f\\\\\frac{B}{f}=4

Hence, B varies directly with f with a constant of proportionality k=4
