Question

x varies inversely as y^2 when x =20 and y=5.If x =50 , then find y.​

Answer 1

Answer:30

If x=20 and y=600

If x=20 and y=600Xy=20×600=12000

If x=20 and y=600Xy=20×600=12000k=12000

If x=20 and y=600Xy=20×600=12000k=12000When x=400 then from equation (i)

If x=20 and y=600Xy=20×600=12000k=12000When x=400 then from equation (i)y×400=k

If x=20 and y=600Xy=20×600=12000k=12000When x=400 then from equation (i)y×400=ky×400=12000

If x=20 and y=600Xy=20×600=12000k=12000When x=400 then from equation (i)y×400=ky×400=12000y=

If x=20 and y=600Xy=20×600=12000k=12000When x=400 then from equation (i)y×400=ky×400=12000y= 400

If x=20 and y=600Xy=20×600=12000k=12000When x=400 then from equation (i)y×400=ky×400=12000y= 40012000

If x=20 and y=600Xy=20×600=12000k=12000When x=400 then from equation (i)y×400=ky×400=12000y= 40012000

If x=20 and y=600Xy=20×600=12000k=12000When x=400 then from equation (i)y×400=ky×400=12000y= 40012000 =30
