3 × 100 + 9 × 10 + 1 + ( 6 × 1 ⁄10 ) + ( 7 × 1 ⁄100 ) + ( 5 × 1 ⁄1000 )
It’s d because all of the other ones are linear
Answer:
t = - 24
Step-by-step explanation:
Given t varies inversely as a then the equation relating them is
t =
← k is the constant of variation
To find k use the condition t = 2 when a = - 4
2 =
( multiply both sides by - 4 )
- 8 = k
t =
← equation of variation
When a =
, then
t =
= - 24
