Question

LAST QUESTION and i pass.The amounts a b and c and decaying exponentially. which will decay to grams fastest. 1. a(t)=8*e^-0.1386t 2.B(t)=10*e^-0.2t 3. c(t)=9*e^-0.1t

Answer 1

are decaying* and to 4 grams

Answer 2

you need to do three equations:
4=8e^-.1386t
4=10e^-.2t
4=9e^-.1t
and solve them. Or, if you have a graphing calculator, graph them and see which reaches y=4 first.

Answer 3

it should be B(t) since the constant k is the largest, but thats with out any calculations

Answer 4

If you graph them, it is B(t)

Answer 5

A(t) takes t = 5.00 B(t) t= 4.58 C(t) = 8.109
