Answer:
t =1.621860432
Step-by-step explanation:
6e^0.25t = 9
Divide each side by 6
6/6e^0.25t = 9/6
e^0.25t = 3/2
Take the ln of each side
ln e^0.25t = ln (3/2)
.25t = ln (3/2)
Divide each side by .25
.25t/.25 = 1/.25 ln (3/2)
t = 4 ln (3/2)
1.62
6e^(0.25t) = 9
e^(0.25t) = 1.5
0.25t × lne = ln1.5
0.25t = 0.4054651081
t = 1.6218604324
