Hi there
The formula of compound interest is
A=p (1+r/k)^kn
A future value?
P present value 12300
R interest rate 0.052
K compounded quarterly 4
N time 1 year
So
A=12,300×(1+0.052÷4)^(4×1)
A=12,952.18
Good luck!
Answer:
The four sides are quadrilateral.
All sides are equal
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
5 ( x - 2) + 4 ( 3 + x) = 20
Distribute
5x -10 +12 +4x = 20
Combine like terms
9x +2 = 20
Subtract 2 from each side
9x+2-2 = 20-2
9x = 18
Divide each side by 9
9x/9 = 18/9
x = 2
Try the suggested explanation (it consists of 3 basic steps).
Let "x" be the first integer:
Second integer would be x+1,
Third integer would be x+2,
<h3>x³ + (x+1)³ + (x+2)³ = 2241</h3>
Using the formula;
<h3>(a+b)³ = a³ + 3a²b + 3ab² + b³ </h3>
x³ + (x+1)³ + (x+2)³ = 2241
x³ + x³ + 3x² + 3x + 1³ + x³ + 6x² + 12x + 2³ = 2241
3x³ + 9x² + 15x + 9 = 2241
dividing the whole equation by 3;
x³ + 3x² + 5x + 3 = 747
x³ + 3x² + 5x = 747 - 3
<h2>x³ + 3x² + 5x = 744</h2>
By graphing this equation, we can see that there is only 1 real root,
that is:
x = 8
Hence,
<h2>
x³ = 512</h2><h2>
(x+1)³ = 729</h2><h2>
(x+2)³ = 1000</h2>
