The half-life of plutonium-241 is 14.4 years. How much of the original 3.6 grams of this
avanturin [10]

\textit{Amount for Exponential Decay using Half-Life} \\\\ A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad \begin{cases} A=\textit{current amount}\\ P=\textit{initial amount}\dotfill &3.6\\ t=\textit{elapsed time}\dotfill &45\\ h=\textit{half-life}\dotfill &14.4 \end{cases} \\\\\\ A=3.6\left( \frac{1}{2} \right)^{\frac{45}{14.4}}\implies A=3.6\left( \frac{1}{2} \right)^{3.125}\implies A\approx 0.41265

Given the function f(x)=9-2x, find x when f(x)=25<br><br> -41<br> 17<br> -8
tatyana61 [14]

Answer:

x = -8

Step-by-step explanation:

Set the function f(x)=9-2x equal to 25, and then solve the resulting equation for x:

9 - 2x = 25.

Isolate the -2x term by subracting 9 from both sides:

-2x = 16

Finally, solve for x by dividing both sides by -2:

x = -16/2, or x = -8
