Six and eighty five thousandths I think
Answer:
1,700
Step-by-step explanation:
The computation of the initial value of the computer is shown below:
Let us assume the value of a certain computer in the first year is X
In the second year, it is 
In the third year, it is 
In the fourth year, it is 
Now it is given that after 3 years, the value of the computer is = 425 i.e equal to

So, X = 1,700
Hence, the initial value of the computer is 1,700
Answer:
(x+3)^2 + (y-2) ^2 = 25
Step-by-step explanation:
Equation of a circle: (x-h)^2 + (y-k)^2 = r^2
Center at (h,k)
Radius=r
A rectangular prism is just a shape that looks like a brick.
If you think about a brick for a few seconds, you'll realize
that it has
-- 2 faces of (length by width)
-- 2 faces of (length by height)
and
-- 2 faces of (width by height).
The dimensions of the brick in question 6 are 8ft, 3ft, and 5ft.
So it has
-- 2 faces of 8ft by 3ft
-- 2 faces of 8ft by 5ft
and
-- 2 faces of 3ft by 5ft .
Can you take over and complete it now ?
Option A:
is the value of 
Explanation:
It is given that the first term is 
The common difference is 
We need to determine the sum of 25 terms.
The sum of terms of an arithmetic series can be determined using the formula, ![S_n=\frac{n[2a_1+(n-1)d]}{2}](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%5B2a_1%2B%28n-1%29d%5D%7D%7B2%7D)
Substituting
,
and 
Thus, we have,
![S_{25}=\frac{25[2(20)+(25-1)(-10)]}{2}](https://tex.z-dn.net/?f=S_%7B25%7D%3D%5Cfrac%7B25%5B2%2820%29%2B%2825-1%29%28-10%29%5D%7D%7B2%7D)
Simplifying the values, we get,
![S_{25}=\frac{25[40+(24)(-10)]}{2}](https://tex.z-dn.net/?f=S_%7B25%7D%3D%5Cfrac%7B25%5B40%2B%2824%29%28-10%29%5D%7D%7B2%7D)
![S_{25}=\frac{25[40-240]}{2}](https://tex.z-dn.net/?f=S_%7B25%7D%3D%5Cfrac%7B25%5B40-240%5D%7D%7B2%7D)
Subtracting the terms within the bracket, we get,
![S_{25}=\frac{25[-200]}{2}](https://tex.z-dn.net/?f=S_%7B25%7D%3D%5Cfrac%7B25%5B-200%5D%7D%7B2%7D)
Multiplying the terms in the numerator, we have,

Dividing, we get,

Thus, the sum of the 25 terms is 
Therefore, Option A is the correct answer.
