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

Answer:

The formula is connecting R and A

 $R = k \frac{1}{A}$

The value of 'K' = 18.15

Step-by-step explanation:

Step(i):-

Given that R is inversely proportional to A

      R ∝ 1 / A

      $R = k \frac{1}{A}$

Given  R = 12 .1 and A = 1.5

       $R = k \frac{1}{A}$

       $12.1 = K (\frac{1}{1.5} )$

      K = 12.1 × 1.5

     K = 18.15

The value of 'K' = 18.15
