Answer:
C. a n =3000(1.05)n-1
Step-by-step explanation:
Arithmetic sequence formula, it is 1.05 because it increases by 1/20th each time. It is n-1 because n-1 is the correct form of arithmetic sequence formulas, without the n-1 it wouldn't work.
A rectangle has two couples of equal sides, so a soccer fields has two 80-meters sides and two 120-meters sides.
This leads to a perimeter of

If you go around it twice, you'll run 800 meters
C=2(pi)r use this equation with 9 in place of r
If ur trying to find the rate its 12.7252%
Step-by-step explanation:
Y = a (b^x)
1) x = 0, y = 3500
=> 3500 = a (b^0)
=> 3500 = a (1)
=> a = 3500
2) growth percent = 3.5% => growth rate = 1.035 = b
=> y = 3500 (1.035)^ x
3) year 2020 => x = 2020 - 2000 = 20
4) y = 3500 (1.035)^ 20 = 6964
Answer: 6964.
