Question

The pressure, p, on a diver varies directly as the depth of the water, d. Using k as the constant of variation, write an equation expressing this relationship. Do not include spaces in your answer. Enter fractions just as you would on the calculator.

Answer 1

Relationships between variables can be direct or inverse. For direct variation, the value of one parameter is a multiple of the other parameter using a proportionality constant, k. To illustrate the relationship between pressure and depth, the equation would be: P=kd
