The first term is 2 and the 20th term is 1048576 .
<u>Step-by-step explanation:</u>
Here we have , If the sum of the first 12 terms of a geometric series is 8190 and the common ratio is 2. We need to Find the first term and the 20th term. Let's find out:
We know that Sum of a GP is :
⇒ 
So ,Sum of first 12 terms is :
⇒ 
⇒ 
⇒ 
⇒ 
Now , nth term of a GP is
⇒ 
So , 20th term is :
⇒ 
⇒ 
⇒ 
Therefore , the first term is 2 and the 20th term is 1048576 .

Answer:
12.3%
Step-by-step explanation:
In this case, despite being different events, they are dependent on each other, therefore the final probability would be the multiplication of both probabilities.
So let L be the probability of being late that is equal to 41% and let T be the probability that the train will leave you and is equal to 30%.
That is to say:
L = 41% = 0.41
T = 30% = 0.3
So:
P = L * T
P = 0.41 * 0.3 = 0.123
So it means that the final probability is 12.3%
Answer:
Amplitude = 4; period = π; phase shift: x = negative pi over two
Step-by-step explanation:
In this problem you have to use the form <em>a sin (bx-c)+d </em>to find the amplitude, period, and phase shift.
Amplitude:4
Period : π
Phase shift: 
I hope this helped! Have an amazing day :)
