Let A(t) represent the amount of money in a bank account at time t years. The rate at which the account is increasing is proport

nikdorinn [45]

Answer:

Step-by-step explanation:

If A(t) represent the amount of money in a bank account at time t years.

The rate at which the account is increasing is proportional to the amount of money in the account, which is modeled by the differential equation:

$\dfrac{dA}{dt}=kA$

First, we solve this differential equation

$\dfrac{dA}{A}=kdt\\$Taking Integrals\\ln A =kt+C, C a constant of integration\\Taking exponents of both sides\\A(t)=Ce^{kt}\\When t=0, A(t)=\$500\\500=C\\Therefore:\\A(t)=500e^{kt}$

At the moment when the amount of money in the account is $1000, the amount is increasing at a rate of $50 per year.

When A(t)=$1000, $\dfrac{dA}{dt}=50$

Therefore:

$50=1000k\\k=50/1000=0.05$

Substituting into our result from A(t) above:

$A(t)=500e^{0.05t}$

To the nearest tenth of a centimeter, what is the circumference of a circle with a radius of 2.5 cm? (Use 3.14 for π.)

maria [59]

To find a circumference of a circle you have to use this expression: C = dπ. d stands for the diameter, so let's find that first.

To find the diameter multiply the radius by 2.
2.5 x 2 = 5

Let's rewrite our equation now. C = 5 · π
15.71 = 5 · π

The answer is 15.71
