$\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$2163\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\dotfill &4\\ t=years\dotfill &3 \end{cases} \\\\\\ A=2163\left(1+\frac{0.04}{4}\right)^{4\cdot 3}\implies A=2163(1.01)^{12}\implies A\approx 2437.322540175$

Special right triangles, find x and y

egoroff_w [7]

Answer:

The answer to your question is x = 17.32; y = 8.67

Step-by-step explanation:

Process

1.- Use trigonometric functions to find x and y

a) sin Ф = $\frac{opposite side}{hypotenuse}$

Ф = 60°

opposite side = 15

hypotenuse = ?

$hypotenuse = \frac{opposite side}{sin \alpha }$

$hypotenuse = \frac{15}{sin 60}$

$hypotenuse = \frac{15}{0.87}$

hypotenuse = 17.32

b) cosФ = $\frac{y}{hypotenuse}$

$y = hypotenuse x cos 60$

$y = 17.32 x 0.5$

y = 8.67
