Dw/dt = k(1200 - w)
dw/(1200 - w) = kdt
-ln(1200 - w) = kt + c
When t = 0, w = 60
-ln(1200 - 60) = c
c = -ln(1140)
a.) For k = 0.8: -ln(1200 - w) = 0.8t - ln(1140)
t = [ln(1140) - ln(1200 - w)]/0.8
For k = 0.9:
t = [ln(1140) - ln(1200 - w)]/0.9
For k = 1:
t = [ln(1140) - ln(1200 - w)]
b.) For k = 0.8
t = [ln(1140) - ln(1200 - 800)]/0.8 = [ln(1140) - ln(400)]/0.8 = 1.3 years
For k = 0.9
t = [ln(1140) - ln(400)]/0.9 = 1.16 years
For k = 1
t = [ln(1140) - ln(400)] = 1.05 years
c.) For maximum weight,
dw/dt = 0
k(1200 - w) = 0
1200 - w = 0
w = 1200
Therefore, the maximum weight for each of the model is 1200 pounds.
Answer:
there are "haters" on the internet that will do anything in their power to tear a person down and criticize them for their work no matter what it is.
but there are also many groups, let's say for example running. there are many running groups where you can have accountability partners and many other people that can relate to you and your journey and have the ability to support you throughout.
