(b) If A(t) is the amount of the investment at time t for the case of continuous compounding, write a differential equation sati

Fantom [35]

Answer:

$A'(t) = rA(t)$

Step-by-step explanation:

Given

$A(t) \to$ Amount

Required

The differential equation

The equation for the amount is:

$A(t) = A_0 * e^{rt}$

Where:

$A_0 \to$ initial amount

$r \to$ rate

$t \to$ time

Differentiate $A(t) = A_0 * e^{rt}$

$A'(t) = A_0 * r * e^{rt}$

So, we have:

$A'(t) = rA_0 * e^{rt}$

From the question, we have: $A(t) = A_0 * e^{rt}$

So, the equation becomes

$A'(t) = rA(t)$

Dao receives an employee discount on the purchase of a new automobile. The automobile that he is interested in has a sticker pri

ZanzabumX [31]

Answer: Dao will pay $ 15,219.2

Step-by-step explanation:

Hi, to answer this question we have to multiply the price of the automobile by the percentage discount in decimal form (divided 100)

18,560 (18/100) = 18,560 (0.18) = $ 3,340.8 (discount amount)

Finally, we have to subtract the discount amount to the automobile's price:

18,560- 3,340.8 =$ 15,219.2

Dao will pay $ 15,219.2.

Feel free to ask for more if needed or if you did not understand something.
