Question

If x varies inversely with ³√y, and x=3 when y=64 find x when y=1000

Answer 1

Answer:

Statement says that x varies inversely with ³√y

According to the above problem, we get

x=k/³√y, where k is a constant

Now, by putting x=3 when y=64

we have to find the value of k

3=k/³√64

3=k/4

k=3×4

k=12

Now, by putting the value of k

we have a find the value of x when y=1000

x=12/³√1000

x=12/10

x=1.2

★ x=1.2 is the right answer.
