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.
Using the concept of supplementary angles, it is found that the measure of angle B is of 135º.
--------------------------------
- If two angles are supplementary, the<u> sum of their measures is of 180º</u>.
- A and B are supplementary, thus:
- The measure of angle A is 1/3 of the measure of angle B, thus:
Replacing in the equation for the sum:
The measure of angle B is of 135º.
