LuckyWell [14K]

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:

Base=7in\\Height=28in

The area will be:

Area=Base*Height=7in*28in=196in^{2}

For the second rectangle, we have:

Base=25in\\Height=30in

The area will be:

Area=Base*Height=30in*25in=750in^{2}

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

TotalArea=FirstRectangleArea+SecondRectangleArea\\\\TotalArea=196in^{2}+750in^{2}=946in^{2}

Have a nice day!
