Question

if a is inversely proportional to √b and a =2 when b=16 find an equation connecting a and b
option 1: √ b = 8/k
option 2: √ b= a/ k
option 3: a= 8/√b
option 4: a√b/k
​

Answer 1

Answer:

Step-by-step explanation:

a is inversely proportional to √b

Then let a=k/√b--------(1)

If a=2 then b=16

2=k/√16

k=2√16

k=8

Thus from(1)

a=8/√b option 3.
