Let t=50
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

  • Algebra -

    I 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
    yx , or some key that resembles a power
    .2
    ± , to make it negative
    =

    to get 24.59509486
