Title: Methods Help
Post by: APK911 on April 16, 2017, 04:42:26 pm

Hi,

If dX/dt=X/2 and X=6 million when t=5, how do you find X when t=10.

Any help would be appreciated.

Thank you!

Antiderive dx/dt then substitute in x= 6 million and t= 5 to find the constant term

Once you have the full equation, substitute t= 10 to find x
