Question 767375: i''m having trouble understanding how these problems work this is the problem.. S = 12.75 e^(-0.0425 t). When S=7.35, find t. i dont know were to start can you please help me Found 2 solutions by Cromlix, solver91311:Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! S = 12.75 e^-0.0425t
Find t when S = 7.35
S = 12.75 e^-0.0425t
7.35 = 12.75 e^-0.0425t
7.35/12.75 = e^-0.0425t
0.57647 = -0.0425t e
log e both sides
(Notice how the -0.0425t comes in front of e)
loge 0.57647 = -0.0425t loge e
(loge e = 1)
loge 0.57647/-0.0425 = t
t = 12.96
Hope this helps.
