If x = (4t^(2)+2) any y = 2t, then find ...

If `x = (4t^(2)+2)` any y = 2t, then find `((dx)/(dy))` at t = 2 sec. (x in meter and t is in second)

A

16

B

8

C

4

D

2

Text Solution

Verified by Experts

The correct Answer is:
B
`((dx)/(dt))=8(t),((dy)/(dt))=2`
`((dx)/(dy))=((8t)/(2))=(4t)`
at `t = 2 sec`
`((dx)/(dy))=8`
