Answer:
T = 200 months
Step-by-step explanation:
Given the model to be
dp/dt = p(10-1-10-7p) where p(0) = 6000
dp/dt = p(-1-7p)
dp/dt = -p+7p²
But since P(0) = 6000
We plug this value into the equation
P = -6000+7(6000)²
P = -6000+252000000
P = 251994000. .limiting value
Differentiating dp/dt w.r.t p
dp/dt = -1+14p
dp'/dt = 14p-1
Plugging p(0) = 6000 into the above we have that
dp'/dt = 14(6000)-1
P' = 84000
Time population would be equal to 3/2 the limiting value
T = 3/2× 84000 = 126000
T = 25199400/126000
T = 199.99months
T = 200 months.
Step-by-step explanation:
rectange part area= width x length
16 x 2
32 in.^2
triangle part area= bxh/2
6x4/2
24/2
12 in.^2
total area = 12+32
44 in.^2
1/4=50
1/4*4=1
1/4*8=2
50*8=400
Distance=400miles
Answer:
y=(20M+30S) kwh
Step-by-step explanation:
Since each windmill generates M kwh then for ywo windmills, each year they will generate 2 M kilowatt hours
For solar panels, since each generates S kilowatts annually then for 3 of them, the power will be 3 S
Total production per year will be 2M+3S
In n years, the energy will be y(n)=(2M+3S)n
When n is 10 years then
y(10)=(2M+3S)10=20M+30S
Therefore, y=(20M+30S)kwh
