Mathematics
1 answer:
timofeeve [1]3 years ago
3 0

Answer:

-1

Step-by-step explanation:

The formula for D/4 is b'^2-ac (where b' = 4/2=2, a=1, c=5). When we use the special discriminant (D/4) we get D/4 = (2)^2-1*5 = 4-5=-1.

Hope this helps!

Part A
olasank [31]
<h3>Answer:</h3>
  • B. f(x) = 3,000(0.85)^x
  • $1566.02
<h3>Step-by-step explanation:</h3>

Part A

At the end of the year, the value of the computer system is ...

... (beginning value) - 15% · (beginning value) = (beginning value) · (1 - 0.15)

... = 0.85 · (beginning value)

Since the same is true for the next year and the next, the multiplier after x years will be 0.85^x. Then the value after x years is ...

... f(x) = (beginning value) · 0.85^x

The beginning value is given as $3000, so this is ...

... f(x) = 3000·0.85^x

____

Part B

For x=4, this is ...

... f(4) = 3000·0.85^4 = 3000·0.52200625 ≈ 1566.02

The value after 4 years is $1566.02.
