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

Answer:
the independent variable goes on the x-axis (the bottom, horizontal one) and the dependent variable goes on the y-axis (the left side, vertical one).
Step-by-step explanation:
Let x = Horseback riding and y = Parasailing
Eq. 1
3x + 2y = 192
Eq. 2
2x + 3y = 213
By elimination:
<span> 2(3x +
2y = 192)</span>
+ -3(2x + 3y =
213)
<span> -5y = - 255</span>
y = $ 51
Substitute y :
3x + 2y = 192
3x + 2(51) = 192
<span>x = $ 30
</span>
<span>Hope this
answer will be a good help for you.</span>
