Question

Write an equation that expresses the relationship. Then solve the equation for u. B varies directly as the cube of t and inversely as u

Answer 1

Below

Explanation:

B varies directly with the cube of t so:

● B = t^3

B varies inversly as u

● B = 1/u

Let's solve the equation for u:

B= 1/u = t^3

● B= 1/u

Switch u and B

● u = 1/B = 1/t^3

If u is 1 then b and t are also 1.
