Hey there!

In order to find out which one is greater, lets convert both of them into percents.

To convert a decimal into a percent, simply multiply the decimal by 100 or move the decimal two places to the right.

So!
0.086 × 100 = 8.6%

Now, we know that 0.086 is equal to 8.6% So, the correct answer is 86%

86% is greater than 0.086.

If dy/dt=-2y and if y=1 when t=0, what is the value of t for which y=1/2

gladu [14]

$\bf \displaystyle \int -2t\cdot dt\implies -2\int t\cdot dt\implies -2\cdot \cfrac{t^2}{2}+C
\\\\\\
-t^2+C=f(x)\qquad 
\begin{cases}
f(x)=y=1\\
t=0
\end{cases}\implies -0^2+C=1\implies C=1
\\\\\\
-t^2+1=f(x)\\\\
-----------------------------\\\\
-t^2+1=f(x)\qquad f(x)=\cfrac{1}{2}\implies -t^2+1=\cfrac{1}{2}
\\\\\\
1-\cfrac{1}{2}=t^2\implies \pm \sqrt{\cfrac{1}{2}}=t\implies \cfrac{1}{\pm \sqrt{2}}=t
\\\\\\
\pm \cfrac{\sqrt{2}}{2}=t\impliedby \textit{with a rationalized denominator}$
