Answer with explanation:

Decay Formula is given by:

       f(x)=I_{0}(1+\frac{R}{100})^t

I_{0}=\text{Initial Amount of radioactive isotope }

R=Rate at which radioactive isotope is decaying.

t=Time Constant

Now, Coming to the Question ,

The Rate at which  radioactive isotope is decaying is given by the formula:

 f(x)=346\times[\frac{1}{2}]^x \\\\f(1)=346 \times \frac{1}{2}\\\\f(1)=173\\\\f(0)=346\times[\frac{1}{2}]^0\\\\f(0)=346 \times 1=346

⇒346= Initial Amount of Radioactive Isotope

Which is more 2/3 or 2/4
goblinko [34]
The answer would be 2/3 is greater than 2/4. Two- thirds is equivalent to 0.67 while 2/4 is equivalent to 1/2 or 0.5. Of course, 0.67 is greater than 0.5.

13+(w)/(7)=-18<br><br> step by step?
kotykmax [81]

w in (-oo:+oo)

w/7+13 = -18 // + 18

w/7+13+18 = 0

1/7*w+31 = 0 // - 31

1/7*w = -31 // : 1/7

w = -31/1/7

w = -217

w = -217
