Tvaries inversely as the square root of u.
t = 3 when u = 4.
find t when u = 49.

t =

Step-by-step explanation:

Given that t varies inversely as the square root of u then the equation relating them is

t = ← k is the constant of variation

To find k use the condition t = 3 when u = 4, thus

k = t = 3 × = 3 × 2 = 6

t = ← equation of variation

When u = 49, then

t = =
