The answer to your question would be the third option
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.
Answer:

Hope this helps and my apologies if this is wrong it should not be though I did it on paper lol.
Answer:
-5/6 = x
Step-by-step explanation:
divide -12 from each side. this should leave you with x = 10/-12. if you simplify this, you should get -5/6
Your answer is: 20
They have 4 different backgrounds and 5 different poses which means you just have to multiply the 4 backgrounds*the 5 different poses to discover how many different pictures you could have at the most.
hope this helps!
