\bf ~~~~~~ \textit{Continuously Compounding Interest Earned Amount}
\\\\
A=Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$3000\\
r=rate\to 5.4\%\to \frac{5.4}{100}\to &0.054\\
t=years\to &5
\end{cases}
\\\\\\
A=3000e^{0.054\cdot 5}\implies A=3000e^{0.27}\implies A\approx 3929.89

A nautical mile is the unit of length used in sea and air navigation. A
Arte-miy333 [17]

Answer:

86.82%

Step-by-step explanation:

A nautical mile = 6,174 feet.

Statute mile =5,360 feet

The percentage of a statute mile to a nautical mile is calculated as:

5360/6174 × 100

= 0.8681567865 × 100

= 86.81567865%

Approximately to the nearest hundredth = 86.82%

Therefore, the percent of a statute mile that is a nautical mile rounded to the nearest hundredth is 86.82%

In a 3-digit number, the middle digit is 3 times the last digit and 4 more than the first digit. All the digits are odd and can
Alexeev081 [22]

Answer:

5

Step-by-step explanation:

This is quite some trial and error question.

Based on the question, the numbers we can use are 1,3,5,7 and 9.

We will start with the middle digit first.

Since the question has stated it is 3 times the last digit, the number has to be in multiples of 3.

So we are left with: 3 and 9.

Then, the question also states the middle digit is 4 more than the first digit. See, its a digit, so the value cannot be less than 1 (odd numbers only and no negative values), so if we subtract 4 to the middle digit to find the first, it should still be a Positive Single numerical value.

3 - 4 = -1

9 - 4 = 5

Therefore, this middle digit is = 9.

Since we know the middle digit = 9

The first digit will be 9 - 4 = 5

The whole value is now 593.

Find the average value of the function y = 6 - x2 over the interval [-1, 4]
kari74 [83]

Answer:

The average value of the function f(x) = 6 - x^{2} over the interval [-1,4] is \frac{5}{3}.

Step-by-step explanation:

The average value of a function over an interval is represented by this integral:

\bar y = \frac{1}{b-a}\cdot \int\limits^{b}_{a} {f(x)} \, dx

Where:

a, b - Lower and upper bounds of the interval, dimensionless.

f(x) - Function, dimensionless.

If a = -1, b = 4 and f(x) = 6 - x^{2}, the average value of the function is:

\bar y = \frac{1}{4-(-1)}\int\limits^{4}_{-1} {6-x^{2}} \, dx

\bar y = \frac{6}{5}\int\limits^{4}_{-1} \, dx - \frac{1}{5}\int\limits^{4}_{-1} {x^{2}} \, dx

\bar y = \frac{6}{5}\cdot x |_{-1}^{4} - \frac{1}{15}\cdot x^{3}|_{-1}^{4}

\bar y = \frac{6}{5}\cdot [4-(-1)]- \frac{1}{15}\cdot [4^{3}-(-1)^{3}]

\bar y = \frac{5}{3}

The average value of the function f(x) = 6 - x^{2} over the interval [-1,4] is \frac{5}{3}.
