Question

Q. It is given that D is inversely proportional to √m and D = 64 when m = 9. Find

(a) the value of m when D =32.
(b) the change in the value of D when the value of m is multiplied by 4.​

Answer 1

Answer:

D is inversely proportional to √m

So,D=K\√m

when D=64 then m=9

putting the given value in above equation K=192

a) 32=192/√m

m = 16

b) m = 4*16= 64

D = 192/√64

D = 24
