Answer:
A=$538.82
Step-by-step explanation:
We're going to use the compounded interest formula:
A=P(1+r/n)^n*t
Where,
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = t is the amount of time at which you're checking how much it's worth (yrs)
Using this information, we can use:
A=500(1+0.025/4)^3*4
A=500(1+0.00625)^12
A=500(1.00625)^12
A=500(1.07763259886)
A=538.82
A=$538.82....
4.2 x 0.8
=3.36 miles completed
4.2 - 3.36 = 0.84 miles left to complete.
A. The scale used to make the model was 125 meters =1 foot. 525 divided by 4.2 equals 125 meters.
B. The model is 84 sheets of plywood tall.
4.2 feet = 50.4 meters 50.4 meters divided by 0.6 equals 84 sheets.
Answer:

Answer:
Step-by-step explanation:
It's geometric. The nth term differs by -5 when compared to the n+1 term.
Sum 0 to n a(-5)^n-1 where a = 2
I think this is what you want, but there is also a formula. See below.
Sum = a (r^n - 1)/(r - 1)
