Mag Posted June 2, 2005 Share Posted June 2, 2005 i dunno how to get the fancy text stuff, so ill just write it out. i have: 96.8 = 72 + 26.6 ^-k(t) Dont i need to know at least K or T to find out one or the other? Link to comment Share on other sites More sharing options...
Ducky Havok Posted June 3, 2005 Share Posted June 3, 2005 Yes you do, but it may just be asking you to solve for k or t. For instance, you could subtract 72, take the log, and divide by -k to get [math]T= -\frac{log_{26.6}(24.8)}{k}[/math] If you want to get values for either you need another equation though.

Mag Posted June 3, 2005 Author Share Posted June 3, 2005 yeah, i need -k, so i can find out t. (and how do you do the equation like that?) Link to comment Share on other sites More sharing options...
