Answer:
The answer is C 18
Step-by-step explanation:
4^2+8/4= 16+2=18
First combine like terms.
9x + 2x = 11x.
That's all you have to do!
Your final answer is 11x - 8!
Have a nice day :)
To calculate the value of the half life we proceed as follows;
a/2=ae^(-2.360t)
the a(s) will cancel and we shall remain with:
1/2=e^-2.360t
introducing the natural logs we get:
ln (1/2)=ln e^(-2.360t)
ln(1/2)=-2.360t
hence;
t=(ln 0.5)/(-2.360)
t=0.294
the answer is t=0.294
