Find the period and amplitude for f(x)= 2sin(3x)

wolverine [178]

Given:

$f(x)=2\sin(3x)$

Required:

To find the period and amplitude of the given function.

Explanation:

Given function is in the form of

$y=a\sin bx$

Here the amplitude is

$=|a|$

Period

$=\frac{2\pi}{b}$

Now consider the given function

$y=2\sin3x$

Here the amplitude is

$\begin{gathered} =|2| \\ =2 \end{gathered}$

And period is

$=\frac{2\pi}{3}$

Final Answer:

The amplitude is 2 and the period is

$\frac{2\pi}{3}$

Answer:

$M.A.D=4$

Step-by-step explanation:

The given data set is :{63, 70, 68, 73, 58, 67}

The mean absolute deviation is the mean of how far all the entries in the data set are from the mean. Follow the procedure below;

find the mean of the data set
find the absolute value of the difference between the mean and each entry.
find the mean of these entries.

The mean is give by:

$\bar X=\frac{\sum x}{n}$

$\bar X=\frac{63+70+68+73+58+67}{6}$

$\bar X=\frac{399}{6}=66.5$

The mean absolute deviation is given by:

$M.A.D=\frac{\sum |x-\bar X|}{n}$

$M.A.D=\frac{|63-66.5|+|70-66.5|+|68-66.5|+|73-66.5|+|58-66.5|+|67-66.5|}{6}$

$M.A.D=\frac{3.5+3.5+1.5+6.5+8.5+0.5}{6}$

$M.A.D=\frac{24}{6}=4$

Find the volume of the cylinder in terms of pi

faust18 [17]

Answer:

V = 54π in³

Step-by-step explanation:

Volume of cylinder = <em>h * πr² --> b * h</em>, where b = area of circle

Substitute: V = 6 * π(3)²

Exponents: V = 6 * 9π

Multiply: V = 54π in³

Jimmy invest $16,000 in an account that pays 7.03% compounded quarterly. How long (in years and months) will it take for his inv

Vladimir [108]

To solve this we are going to use the compound interest formula $A=P(1+ \frac{r}{n})^{nt}$
where:
$P$ is the investment
$r$ is the interest rate in decimal form
$n$ is the number of times the interest is compounded per year
$t$ is the time in years
$A$ is the amount after $t$ years

First, lets convert the interest rate to decimal dividing it by 100%:
$r= \frac{7.03}{100} =0.0703$
Next, lets find $n$ . Since we know that the interest is compounded every 4 months (quarterly), it will be compounded $\frac{12}{4} =3$ times in a year, so $n=4$ .
We also know that $A=23000$ and $P=16000$ , so lets replace all the quantities into our compound interest formula:
$25000=16000(1+ \frac{0.0703}{3})^{3t}$
$25000=16000(1.0234)^{3t}$

Notice that the the number of years $t$ is in the exponent, so we have to use logarithms to bring it down. But first lets divide both sides by 16000 to isolate the exponential expression:
$\frac{25000}{16000} =(1.0234)^{3t}$
$(1.0234)^{3t} = \frac{25}{16}$
$ln(1.0234)^{3t} =ln( \frac{25}{16} )$
$t= \frac{ln( \frac{25}{16}) }{3ln(1.0234)}$
$t=6.43$

Now that we know $t=6.43$ , the last thing to do is convert 0.43 years to months:
$(0.43 years)( \frac{12months}{1year} )=5.16months$

We can conclude that Jimmy's investment will take 6 years and 5 months to reach $25,000.
