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:
Step-by-step explanation:
Add and subtract the square of half the x-coefficient:
x² -10x +(-5)² -(-5)² +15
Express the first three terms as a square; simplify the remaining terms.
(x -5)² -10
This expression describes a parabola that opens upward and has its vertex at (x, y) = (5, -10). The minimum value is -10.
Answer:
1400
Step-by-step explanation:
3.5% of listeners rated the song as 1 star
49 listeners rated the song as 1 star
49 listeners = 3.5% of listeners
we want to find 100% of listeners. we can do this by multiplying both sides of the equation by 100/3.5, getting one side to 100% and the other to what it is equal to
49 * 100/3.5 listeners = 100% of listeners = 1400
