Answer:
9990 years
Step-by-step explanation:
The exponential function with given values filled in can be solved for the unknown using logarithms.
__
Q(t) = 12 = 36e^(-0.00011t)
1/3 = e^(-0.00011t) . . . . . . divide by 36
ln(1/3) = -0.00011t . . . . . . take natural logs
t = ln(1/3)/(-0.00011) . . . . divide by the coefficient of t
t ≈ 9990 . . . years

<h2>
Hello!</h2>
The answer is:
The area of this figure is 946 square inches.
<h2>
Why?</h2>
We can see that the figure is composed by two rectangles with diferrent dimensions, so, to calculate the area of the entire figure.
So,
For the first rectangle, we have:

The area will be:

For the second rectangle, we have:

The area will be:

Now, calculating the area of the entire figure, we have:

Have a nice day!
