The following differential equation is separable as it is of the form dP/dt = g(P)h(t).

dedylja [7]

Answer:

$P(1-P) = Ae^t$

Step-by-step explanation:

given differential equation is

$\frac{dP}{dt} =P-P^2\\\frac{dP}{dt} = g(P) h(t)\\g(P) = P-P^2\\h(t) = 1$

So this is separable

We separate as

$\frac{dP}{P-P^2} =1dt\\\frac{dP}{P(1-P)} =1dt$

Resolve into partial fractions to solve this

$dP(\frac{1}{P}+ \frac{1}{1-P} ) = 1dt\\ln P(1-P) = t+C\\P(1-P) = Ae^t$

So solution is $P(1-P) = Ae^t$

What are the domain and range of the function?

wel

Answer: SECOND OPTION

Step-by-step explanation:

By definition the domain is the set of value of the input (x values) shown in the table attached in the problem.

By definition the domain is the set of value of the output (y values) shown in the table attached in the problem.

Therefore, keeping the above on mind, you have:

Domain:{-2,-1,0,1,2,3}

Range:{-8,-1,0,1,8,27}

Khalid and Jesse took different overnight trains. The graph shows the relationship between the total distance Khalid traveled an

Usimov [2.4K]

Answer:

Jesse - 150 miles per hour.

Step-by-step explanation:

On the graph, it shows that the rise is 140 and the run is 1. 140/1 is 140, making the slope for Khalid is 140. The equation (y = 150x) shows that the slope is 150 (y = mx). Since 150 is greater than (>) 140, Jesse's train is more faster than Khalid since she is moving at 150mph rather than 140mph.

The mean is 36 and the standard deviation is 5.02.

The mean is given by
μ = np = 120*0.3 = 36.

The standard deviation is given by
σ = √(n*p*(1-p)) = √(120*0.3*0.7) = √25.2 = 5.02.
