(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

DifferentiateA(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)

PLEASE HELP FAST!!!!!!!!
seropon [69]

Answer:

Option B. -j = -h/-k is not correct

Step-by-step explanation:

As from the given scenario both the negative signs will be cancelled out giving positive j : -h/-k = -j

First option has: -j = -h/k In this case also the negative sign from both sides would be cancelled out.

Second option has: -h/-k = -j In this case negative signs cannot be cancelled out.

Third option has: h/-k = -j , negative sign would be cancelled from both sides.

Fourth option has: h/k = j , no negative sign on either side.

i hope it will help you!
