Hello,
The question is
<span>"What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8?"
It is a geometric sequence =>U(2)=U(1)*r==>-8=2*r ==>r=-4
U(1)=2=2*(-4)^0
U(2)=-8=2*(-4)=2*(-4)^1
U(3)=32=-8*(-4)=2*(-4)(-4)=2*(-4)^2
U(4)=-128=32*(-4)=2*(-4)^3
...
U(n)=2*(-4)^(n-1) where n>=1.
Answer C

Answer:
To my understanding, it's not a number.
Instead, it's a rank.
Try to answer questions until you rank up. Then you can chat.
Answer:
1200 is ur wsener
Step-by-step explanation:
Answer:
The answer is $22.75! (A)
Step-by-step explanation:
All you have to do is subtract $36.50 by $13.75 and get the amount of the 2nd piggy bank.
22.75 + 13.75 = 36.50
The solution of given system of equations is
x=8, y=3
Step-by-step explanation:
Given equations are:
Multiplying eqn 1 by 5
Multiplying eqn 2 by 2
Subtracting eqn 4 from eqn 3
Dividing both sides by 41
Putting y=3 in equation 1
Dividing both sides by -2
Hence,
The solution of given system of equations is
x=8, y=3
