Answer:

To calculate annual compound interest, multiply the original amount of your investment or loan, or principal, by the annual interest rate. Add that amount to the principal, then multiply by the interest rate again to get the second year's compounding interest

Step-by-step explanation:

A = P (1+ r/n) ^nt

A = final amount is found if you input 12 months at r

P = initial principal balance = $100 if every month

r = interest rate then interest rate will be 12 month

n = number of times interest applied per time period = 1

t = number of time periods elapsed t = eg 10

A car travels 0.75 miles per minute. Explain how you could use proportional reasoning to find how far the car travels in one hou

Zina [86]

Notice the proportions below. Keep in mind that 1 hour is 60 minutes.

$\bf \begin{array}{ccll}
miles&minutes\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
0.75&1\\
x&60
\end{array}\implies \cfrac{0.75}{x}=\cfrac{1}{60}\implies \cfrac{0.75\cdot 60}{1}=x\implies 45=x$

A terminal ray passes through (12,-5). Fine the value to all six trig functions

Harman [31]

Okay, here we have this:

Considering the provided angle, we are going to calculate the requested trigonometric functions, so we obtain the following:

So the first thing we will do is calculate the length of the hypotenuse, that is, the distance between the given point and the origin, then we have:

$\begin{gathered} r=\sqrt{(12-0)^2+(-5-0)^2} \\ r=\sqrt{12^2+(-5)^2} \\ r=\sqrt{144+25} \\ r=\sqrt{169} \\ r=13 \end{gathered}$

Now we proceed to find the value of each ratio:

$sin\beta=\frac{y}{r}=\frac{-5}{13}$ $cos\beta=\frac{x}{r}=\frac{12}{13}$ $tan\beta=\frac{y}{x}=\frac{-5}{12}$ $csc\beta=\frac{r}{y}=\frac{13}{-5}=-\frac{13}{5}$ $sec\beta=\frac{r}{x}=\frac{13}{12}$ $cot\beta=\frac{x}{y}=\frac{12}{-5}=-\frac{12}{5}$
