3 (3/1) represents the slope and -4 is the y-intercept
Koalagirl133 I think this is the answer I don't know if it is 9,540,000× 10 = 94, 500, 000
A: I think it’s 9(−5+9n+10n2)
Step-by-step explanation:
The original functions are: f(n) = 500 and g(n) = [9/10]^(n-1)
A geometric sequence combining them is: An = f(n)*g(n) = 500*[9/10]^(n-1):
Some terms are:
A1= 500
A2 = 500*[9/10]
A3 = 500*[9/10]^2
A4 = 500*[9/10]^3
....
A11 = 500*[9/10]^10 ≈ 174.339
Answer: the third option, An = 500[9/10]^(n-1); A11 = 174.339
