Answer
Question 1
Explanation:
Step1: Identify the formula
The formula for continuous - compounding is $A = Pe^{rt}$, where $A$ is the amount of money in the account after $t$ years, $P$ is the principal amount (initial deposit), $r$ is the annual interest rate (in decimal form), and $t$ is the number of years. Here, $P = 6000$, $r=0.08$, and $t = 10$.
Step2: Substitute values into the formula
$A=6000\times e^{0.08\times10}=6000\times e^{0.8}$.
Step3: Calculate the value
Using a calculator, $e^{0.8}\approx2.22554$, so $A = 6000\times2.22554 = 13353.24$.
Answer:
$13353.24$
Question 2
Explanation:
Step1: Identify the formula
Use the continuous - compounding formula $A = Pe^{rt}$. Here, $P = 6000$, $r = 0.07$, and $t=5$.
Step2: Substitute values into the formula
$A=6000\times e^{0.07\times5}=6000\times e^{0.35}$.
Step3: Calculate the value
Using a calculator, $e^{0.35}\approx1.41907$, so $A=6000\times1.41907 = 8514.42$.
Answer:
$8514.42$
Question 3
Explanation:
Step1: Identify the formula
The continuous - compounding formula is $A = Pe^{rt}$, and we want to find $P$. Rearranging the formula for $P$ gives $P=\frac{A}{e^{rt}}$. Here, $A = 2000$, $r = 0.08$, and $t = 10$.
Step2: Substitute values into the formula
$P=\frac{2000}{e^{0.08\times10}}=\frac{2000}{e^{0.8}}$.
Step3: Calculate the value
Since $e^{0.8}\approx2.22554$, then $P=\frac{2000}{2.22554}\approx898.65$.
Answer:
$898.65$
