Question

V varies inversely with T and V=12 when T=6. Which equation shows this relationship
A)v= 2/T
B) V=72T
C)V=2T
D)v= 72/T

Answer 1

Answer:

D

Step-by-step explanation:

Given V varies inversely as T, then the equation relating them is

V = $\frac{k}{T}$ ← k is the constant of variation

To find k use the condition, V = 12 when T = 6

k = VT = 12 × 6 = 72

V = $\frac{72}{T}$ ← equation of variation
