A typical credit card company charges 18% annual interest,

AnnZ [28]

Answer:

$1,519

Step-by-step explanation:

Given that :

Balance = principal = $520

Time (t) = 6 years

Annual. Interest rate (r) = 18% = 0.18

Using the compound interest formula:

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

n = number of times interest is applied per period ; A = final amount

Since interest is compounded monthly, n = 12

A = 520(1 + 0.18/12)^(12 * 6)

A = 520(1 + 0.015)^72

A = 520(1.015)^72

A = 520(2.9211579)

A = 1519.0021

Hence, final amount = $1519

Answer:

XW = 4 units

Step-by-step explanation:

Given tanf° = $\frac{2}{1}$ , then

tanf° = $\frac{opposite}{adjacent}$ = $\frac{YW}{XW}$ = $\frac{8}{XW}$ = $\frac{2}{1}$ ( cross- multiply )

2XW = 8 ( divide both sides by 2 )

XW = 4

Ciao, come stai?

1) Per prima cosa, dobbiamo trovare la misura della base più grande. Scomponendo la figura possiamo visualizzare un triangolo e un quadrato. Ci sono somiglianze con gli angoli. Quindi è un triangolo rettangolo. Applichiamo il teorema di Pitagora:

$a^2=b^2+c^2\\95^2=b^2+76^2\\57=b$
