A car is purchased for $28,000. After each year, the resale value decreases by

Dennis_Churaev [7]

$\bf \qquad \textit{Amount for Exponential Decay}\\\\
A=I(1 - r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &28000\\
r=rate\to 35\%\to \frac{35}{100}\to &0.35\\
t=\textit{elapsed time}\to &3\\
\end{cases}
\\\\\\
A=28000(1-0.35)^3\implies A=28000(0.65)^3\implies A=7689.5
\\\\\\
\textit{which rounds up to }7689$

Expand the function. f(x)=(x + 7)^3

Marta_Voda [28]

Answer:

$f(x) = {x}^{3} + 21 {x}^{2} + 147x + 343$

Step-by-step explanation:

$(x + 7 {)}^{3}$

${x}^{3} + 3 {x}^{2} \times 7 + 3x \times {7}^{2} + {7}^{3}$

${x}^{3} + {x}^{2} \times 7 + 3x \times 49 + 343$

${x}^{3} + 21 {x}^{2} + 147x + 343$

Therefore:

$f(x) = {x}^{3} + 21 {x}^{2} + 147x + 343$

How do i do this ???????? im a confusion

victus00 [196]

40/.10

okay so plan 1 is 20$ a month plus .10 cent each message

plan 2 40$ unlimited text.

now 20 is half of forty , so another 20 to get to 40

20/.10 gives you 200 messages until you reach the 40 dollar mark.
