Question

f is inversely proportional to √g. When f=10, g=121
Work out g when f=11

Answer 1

Answer:

g = 100.

Step-by-step explanation:

Inverse variation, so:

f = k/√g     where k is the constant of proportionality.

Plugging in the given values:

10 = k/√121

10 = k / 11

k = 10^11 = 110.

So the relation is:

f = 110/√g

When f = 11:

11 = 110/√g

11√g = 110

√g = 110/11 = 10

So g = 10^2 = 100.
