Question

p varies directly as square of q and p is equal to 4 when q=2/3 . find p when q=8/3​

Answer 1

Step-by-step explanation:

given: p varies directly as square of q (i.e) p ~ q^2

that is p=k q^2 , where k is a constant

when q=2/3 p=4

4=k(2/3)^2

4=k(4/9) ====> 4k/9= 4

4k=36 ====> k=9

when q=8/3

p= 9 (8/3)^2

p= 9×64/9

p= 64
