Answer:

about 81 years

Step-by-step explanation:

A graphing calculator can give you the answer easily.

You can solve the problem algebraically by putting in the given number and solving for t.

30000 = 32000/(1 +12.8e^(-.065t))

12.8e^(-.065t) = (32000/30000) -1 = 1/15

e^(-.065t) = 1/(15·12.8) = 1/192 . . . . . divide by 12.8

-0.065t = ln(1/192) ≈ -5.257 . . . . . . take the natural log

t = -5.257/-0.065 ≈ 80.88 . . . . . . . .divide by the coefficient of t

It will take about 81 years for the number of trees to reach 30,000.

Find the area of an equilateral triangle that has perimeter of 24 m.

mafiozo [28]

we know the perimeter is 24, and is an equilateral triangle, so it has three equal sides, so each side is 24 ÷ 3 = 8.

$\bf \textit{area of an equilateral triangle}\\\\ A=\cfrac{s^2\sqrt{3}}{4}~~ \begin{cases} s=side's\\ \qquad length\\ \cline{1-1} s = 8 \end{cases}\implies A=\cfrac{8^2\sqrt{3}}{4}\\\\\\ A=16\sqrt{3}\implies A\approx 24.71$
