Newton’s law of cooling states that dx/dt= −k(x − A) where x is the temperature, t is time, A is the ambient temperature, and k

Vadim26 [7]

Answer:

(a) The solution to the differential equation is x = A_0Coswt + Ce^(-kx)

(b) The initial condition t > 0 will not make much of a difference.

Step-by-step explanation:

Given the differential equation

dx/dt= −k(x − A); t > 0, A = A_0Coswt

(a) To solve the differential equation, first separate the variables.

dx/(x - A) = -kdt

Integrating both sides, we have

ln(x - A) = -kt + c

x - A = Ce^(-kt) (Where C = ce^(-kt))

x = A + Ce^(-kx)

Now, we put A = A_0Coswt

x = A_0Coswt + Ce^(-kx) (Where C is constant.)

And we have the solution.

(b) Since temperature t ≠ 0, the initial condition t > 0 will not make much of a difference because, Cos(wt) = Cos(-wt).

It is not any different from when t < 0.

After 50 soccer games, the ratio of wins to losses is 3:7. How many games did the team win? Explain how you found your answer

zalisa [80]

Answer:The team won 15 games

Step-by-step explanation:

Given no of soccer games =50

Ratio of wins to losses =3:7

Let no of wins = $3x$

and no of losses = $7x$

Now

$3x+7x=50$

$10x=50$

Dividing both sides by 10

x=5

So no of wins =3x = $3\times5$

=15

We found the answer as 10 parts equals 50

So 3 parts equals 15
