Answer:

13/20

Step-by-step explanation:

To get this answer, you add 7 and 13 together and you get 20. Then you put 13 over 20 and that becomes 13/20. Since 13/20 cannot be simplified any further, that is your final answer.

Hope this helps, have a great day/night!

The half-life of Radium-226 is 1590 years. If a sample contains 200 mg, how many mg will remain after 1000 years?
adell [148]

Answer: 129.33 g

Step-by-step explanation:

$$Let $p=A \cdot e^{n t}$ \\$(p=$ present amount, $A=$ initial amount, $n=$ decay rate, $t=$ time)

\begin{aligned}&\Rightarrow \text { Given } p=\frac{A}{2} \ a t  \ t=1590 \\&\Rightarrow \frac{1}{2}=e^{1590n} \Rightarrow n=\frac{\ln (1 / 2)}{1590}=-0.00043594162\end{aligned}

$$If $A=200 \mathrm{mg}$ and $t=1000$ then,$$\begin{aligned}P &=200 e^{\left(\frac{\ln \left(1/2\right)}{1590}\right) \cdot 1000} \text \\\\&=129.33 \text { grams}\end{aligned}$$

Arithmetic of functions
Rzqust [24]

Its B.

If f(x)=4x+1 and g(x)=x^2-5 then, (\frac{g}{f})(x)=\frac{x^2-5}{4x+1} and x\neq-\frac{1}{4} because if x were -\frac{1}{4} then you would have division by 0.

Hope this helps.
