Answer:
$5151.42
Step-by-step explanation:
The formula you need is

where A(t) is the amount after the compounding, P is the initial investment, r is the interest rate in decimal form, n is the number of compoundings per year, and t is time in years. The info we have is
A(t) = 8000
P = ?
r = .09
t = 5
Filling in we have

Simplifying a bit and we have
Now we will add inside the parenthesis and raise 1.045 to the 10th power to get
8000 = P(1.552969422)
Divide away the 155... on both sides to solve for P.
P = $5151.42
Answer: 1st answer, 2nd answer, and 4th answer
Step-by-step explanation:
Add 6 to x^2 to translate function to the left (x+6)^2, then minus 5 to move down: (x-6)^2-5
So you must talking about the circumference I guess.
3.14( pi) * diameter.
The proportion would go as follows:
2 C
5 = 145 Its hard to type that but 2 would go over the 5 and an equals sign would be in the middle, then C over 45. To solve then take 145 times 2 and divide it by 5.
Hope this helps.
