Answer:
$ 12400
Step-by-step explanation:
P =$10,000
r= 10%
t = 3 year
I = $ 2400
Amount = P + I = 10000 + 2400 = $ 12,400
Answer: (x+8)²
Step-by-step explanation:
When you complete the square, the factor is squared. You want to first factor the equation.
x²+16x+64=0
(x+8)(x+8)=0
Now that we have factored the equation, we can put in into squares.
(x+8)²
Answer:
A=0.125
B=0.125
Step-by-step explanation
for both you would divide 0.5 by 4. you would cut 0.125 off of each side, but two sides together would 0.25

Answer:
an = 12(-1/2)^(n-1)
Step-by-step explanation:
Your sequence has a common ratio of ...
r = -6/12 = 3/-6 = -1/2
The first term is 12.
The explicit formula for the general term of a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
Using the values for this sequence, the explicit formula you want is ...
an = 12·(-1/2)^(n -1)
__
This could be rearranged to be ...
an = -24·(-2)^(-n)
