a company borrowed 25,000 and was charges 3.5% and was charged 2,625 in interet...how long was it before the company repaid the

Sladkaya [172]

We'll have to assume that interest is charged annually.

interest = i = p*r*t, where p is the initial amount ($25000), r is the annual interest rate as a decimal fraction, and t is the length of time, in years.

Then $2625 = $25000*0.035*t. Solve for t:

$2625
------------ = 0.035t = 0.105. Dividing both sides by 0.035, we get
$25000

t = 3 years (answer)

HELP FAST PLEASE<br> Find u*v, if u=13j and v=i+3j

Flauer [41]

$\bf \begin{cases}
u=13j\implies 0i+13j\implies \ \textless \ 0,13\ \textgreater \ \\
v=i+3j\implies 1i+3j\implies \ \textless \ 1,3\ \textgreater \ 
\end{cases}
\\\\\\
\ \textless \ 0,13\ \textgreater \ \cdot \ \textless \ 1,3\ \textgreater \ \implies (0\cdot 1)+(13\cdot 3)\implies 39$

Find the approximate solution(s) to each of the following equations graphically. Use technology to support your

ser-zykov [4K]

Answer: x" = 5.69

Step-by-step explanation:

The graphic solution is attached.

Verifying the solution:

Existence condition: x > 0

2x - 4 = √x + 5

√x =2x - 4 - 5

√x =2x - 9 (²)

x = (2x - 9)²

x = 4x² - 36x + 81

4x² - 36x - x + 81 = 0

4x² - 37x + 81 = 0

Δ = -37² - 4.4.81 = 1369 - 1296 = 73

x = 37 ±√73/8

x' = 3.55

x" = 5.69

checking:

2*3.55 - 4 = 3.1

√3.55 + 5 = 6.88 Its not the same ∴ 3.55 is not a solution

2*5.69 - 4 = 7.39

√5.69 + 5 = 7.39 ∴ it's the only solution
