y=30(2.7)^-0.004t

y=30(2.7)^-0.004(50)

y=30(2.7)^-.2

Need help with proper technique for using TI-83 to calculate.

Thanks

**Reiny**, Sunday, November 27, 2011 at 2:22pmI don't have a TI , mine is an old SHARP.

But most work pretty well the same way.

On mine I would type:

30

x

2.7

y^{x}, or some key that resembles a power

.2

± , to make it negative

=

to get 24.59509486
