Answer:

$y=3\sin x$

Step-by-step explanation:

The function repeats the same shape after every $2\pi$ units.

The function is symmetric with respect to the origin so it is a sine function.

The amplitude is 3 because the graph has range $-3\le y\le 3$

The equation is of the form $y=a\sin x$ where a=3 is the amplitude.

Hence the required equation is $y=3\sin x$

Answer:

There were total 4 samples collected and each sample had a sample size of n = 100.

Step-by-step explanation:

We are given the following information in the question:

Collection of samples:

$1^{st}\text{ sample was done in January with a sample size n = 100}$

$2^{nd}\text{ sample was done in March with a sample size n = 100}$

$3^{rd}\text{ sample was done in June with a sample size n = 100}$

$4^{th}\text{ sample was done in September with a sample size n = 100}$

Hence, there were total 4 samples collected and each sample had a sample size of n = 100.

Find the geometric sum: 40 + 20 + 10 + … + 0.078125

sveticcg [70]

$S=40+20+10+\cdots+0.078125$
$S=40\left(1+\dfrac12+\dfrac14+\cdots+\dfrac1{512}\right)$
$S=40\left(1+2^{-1}+2^{-2}+\cdots+2^{-9}\right)$

$2^{-1}S=40\left(2^{-1}+2^{-2}+2^{-3}+\cdots+2^{-10}\right)$

$\implies S-2^{-1}S=40\left(1-2^{-10}\right)$
$\implies\dfrac12S=40\left(1-\dfrac1{1024}\right)$
$\implies S=80\left(1-\dfrac1{1024}\right)=\dfrac{5115}{64}=79.921875$
