Answer:
- D. 24736 people and 29 years
Step-by-step explanation:
<u>The model given is:</u>
<u>Population in 2020, t = 20</u>
- P = 16581*e^(0.02*20) = 24736 people (rounded)
<u>Population of 30000:</u>
- 30000 = 16581*e^(0.02t)
- e^(0.02t) = 30000/16581
- e^(0.02t) = 1.80929
- ln e^(0.02t) = ln 1.80929
- 0.02t = 0.5929
- t = 0.5929/0.02
- t = 29.645 ≈ 29 years
Correct choice is D
Answer: (-2, 8)
Explanation:
Plug x = -2 into the second equation. Isolate y.
5x+3y = 14
5(-2)+3y = 14
-10+3y = 14
3y = 14+10
3y = 24
y = 24/3
y = 8
We have x = -2 lead to y = 8.
Therefore, the ordered pair (x,y) = (-2,8) is the solution to this system.

(Multiply by 400)
$400=336€
Answer:
False
Step-by-step explanation:
the domain is the set of numbers you can plug in, and the range is what comes out
4 is shown in both ovals, but we see that there is no arrow pointing from the left oval to the 4 in the right oval, meaning that no value in interval [1,5] has a value of 4.
