How many atoms are in the molecule serotonin

We have that between the indicated value of r (of the polar coordinates) and x and y (of the cartesian coordinates) there is a relation because they form a triangle. If r changes, then the value of x and y will change.

<h2>STEP 1: given equation</h2>

Using the given equation

r = 2 secØ

we have that

$\begin{gathered} r=2secØ \\ \downarrow \\ \frac{r}{2}=secØ \end{gathered}$ <h2>STEP 2: secØ equation</h2>

Observing the image of the initial explanation we have a right triangle, we know that the equation of

secØ for any right triangle is given by:

$\sec Ø=\frac{\text{hypotenuse}}{\text{adjacent side}}$

In this case,

hypotenuse = r

adjacent side = x

then,

$\begin{gathered} \sec Ø=\frac{\text{hypotenuse}}{\text{adjacent side}}=\frac{r}{x} \\ \sec Ø=\frac{r}{x} \end{gathered}$ <h2>STEP 3: comparison between given equation and secØ equation</h2>

Then, we have that:

$\begin{gathered} \sec Ø=\frac{r}{x} \\ \sec Ø=\frac{r}{2} \end{gathered}$

This means that:

$\begin{gathered} \frac{r}{x}=\sec Ø=\frac{r}{2} \\ \downarrow \\ \frac{r}{x}=\frac{r}{2} \end{gathered}$

Then,

x = 2

The equation in cartesian coordinates is x=2.

Answer: x=2

six and five hundredths in standard form; four and sixty eight thousandths in standard form; nine and twenty hundredths in stand

xeze [42]

The standard form values of the expression can be written in order to be easily understandable.

Values are written in standard form so that these values can be used in calculation and it makes calculation more easy. In standard form, six and five hundredths is written as 0.0605. Four and sixty-eight thousandths in standard form is written as 0.0068. Nine and twenty hundredths in standard form is written as 0.0920. Twenty-one and six hundred five thousandths in standard form is written as 0.2165. Five and thirty-eight thousandths as a decimal is 0.0538. Thirty-five thousandths in decimal form is 0.0035. Twelve and thirty-four hundredths written in standard form is 0.1234. Nine and two hundred thirty-five thousandths in decimal form is 0.09235.
