226Ra has a half-life of 1599 years. How much is left after 1000 years if the initial amount was 10 g?

Ray Of Light [21]

$\bf \textit{Amount for Exponential Decay using Half-Life}\\\\
A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &10\\
t=\textit{elapsed time}\to &1000\\
h=\textit{half-life}\to &1599
\end{cases}
\\\\\\
A=10\left( \frac{1}{2} \right)^{\frac{1000}{1599}}$

Find the GCF of 4y and 12y

Marianna [84]

Answer:

4y

Step-by-step explanation:

To find the greatest common factor of 2 numbers, factor both of the numbers:

4: 1, 2, 4

12: 1, 2, 3, 4, 6, 12

The greatest factor here in both of these lists is 4. These numbers also both have a factor of y, so you multiply those together and get 4y.

$4\times y=4y$

Which ordered pairs are solutions to the inequality 2x+3y≥−1 ?

Pavlova-9 [17]

There are many pairs that are solutions to this inequality. You can find them all by graphic this on a coordinate plane and then shading the region.

You can also plug any of the ordered pairs that they give you into the equation and see if they produce a true statement.
