X varies directly as the square of s and inversely as t. How does x change when s is doubled? When both s and t are doubled?© BrainMass Inc. brainmass.com March 4, 2021, 5:42 pm ad1c9bdddf
(I have attached a MS Word document solution also.)
(s^2 is the same as s squared.)
To say x varies directly as the square of s and inversely as t is to say that x is proportional to s^2/t.
So x = k s^2/t, where k is some constant (this is ...
The change in variables with direct and inverse proportions is examined.
