Answer:
90 days.
Step-by-step explanation:
dy/dt = - 0.0032y
dy = -0.0032y dt
dy/y = -0.0032 dt
Integrating:
ln y = -0.0032t + c where c is some constant
y = e^(-0032t) + e^c
y = A e^(-0032t) where A is a constant.
At time 0 we can let y = 1 so in that case A = 1
When there is 0.75 of y left:
0.75 = e^-0032t
ln 0,75 = -0032 t
t = ln 0.75 / -0032
t = 90.
Answer:2?
Step-by-step explanation:
The answer is
2^6(1-3n)×2^4(3n-3)=2^6(-3n-3).
2^(6-18n)×2^(12n-12)=2^(-18n-18).
(6-18n)×(12n-12)=(-18n-18).
6-18n×12n-12=18n-18.
6-12×-18n-12n=18n-18
-6×-30n=18n-18.
-6×18=-18+30
-108=48n.
n= -108/48.
n=-2.25.
