Question 790549
Convert the given exponential function to the form indicated. Round all coefficients to four significant digits.
--------------------
f(t) = Qo/7e^−kt 
------- 
f(t) = 6(0.981)^t 
------
Qo = 6
----
1/(7e^-(k) = 0.981
e^-k = 1/(7*0.981)
e^k = 7*0.981
k = ln(7*0.981) = 1.9267
------------------
Ans:
f(t) = 6/7e^-(1.9267t)
