Answer:
$ 637.17
Step-by-step explanation:
First, let's convert the interest per year (iy) to interest per month (im):
(1 + im)¹² = 1 + iy
(1 + im)¹² = 1 + 0.08
1 + im = ![1.08^{1/12}](https://tex.z-dn.net/?f=1.08%5E%7B1%2F12%7D)
1 + im = 1.00643
im = 0.00643
im = 0.643%
The total amount (A) of an investment is:
![A = R*(\frac{(1+im)^{n}-1}{im})](https://tex.z-dn.net/?f=A%20%3D%20R%2A%28%5Cfrac%7B%281%2Bim%29%5E%7Bn%7D-1%7D%7Bim%7D%29)
Where R is the amount invested per month, and n the number of monthes. So:
![10,000 = R*(\frac{(1.00643)^{15}-1}{0.00643} )](https://tex.z-dn.net/?f=10%2C000%20%3D%20R%2A%28%5Cfrac%7B%281.00643%29%5E%7B15%7D-1%7D%7B0.00643%7D%20%29)
10,000 = R*15.6943
R = $ 637.17
Answer:
6x^2
Step-by-step explanation:
=2x^2•3x^0
=2x^2•3×1 (As any thing to the powe 0 is 1)
=2x^2•3
=2•3x^2
=6x^2
Answer:
486 in³
Step-by-step explanation:
Area of base = l*b = 81sq. inches
h = 6 inches
Volume of the box = lbh = 81 * 6 = 486 cubic inches
