\bf \qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &18800\\ r=rate\to 12\%\to \frac{12}{100}\dotfill &0.12\\ t=\textit{elapsed time}\dotfill &13\\ \end{cases} \\\\\\ A=18800(1-0.12)^{13}\implies A=18800(0.88)^{13}\implies A\approx 3568.0636019

Answer:

WT=63

Step-by-step explanation:

\frac{56}{5 \times x + 3}  =  \frac{40}{4 \times x - 3}  \\ x = 12

So

5 \times x + 3 = 5 \times 12 + 3 = 63

Need help quick!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Nookie1986 [14]

Answer:

-10,000 / -2000, although 10,000/2000 gives the same answer.

Step-by-step explanation:

The equations -10,000/2000 and 10,000/-2000 are negative, and negative days do not make sense, thus eliminating those answers.

Also, she wants to descend 10,000 feet, so that makes it -10,000 int he equation.

katrin [286]

Answer:

8x + 9

Step-by-step explanation:

Treat the question as 2 separate brackets

First expand 3(2x + 1) :

6x + 3

Then expand 2(x + 3) :

2x + 6

Now add the two answers together and simplify :

= 6x + 3 + 2x + 6

= 8x + 9

hope this helps :)
