Question

R is inversely proportional to A

R = 12.1 when A =1.5 a) work out a formula connecting R and A

Answer 1

The formula is connecting R and A

`R = k (1)/(A)`

The value of 'K' = 18.15

Explanation:

Step(i):-

Given that R is inversely proportional to A

R ∝ 1 / A

`R = k (1)/(A)`

Given R = 12 .1 and A = 1.5

`R = k (1)/(A)`

`12.1 = K ((1)/(1.5) )`

K = 12.1 × 1.5

K = 18.15

The value of 'K' = 18.15
