<em>Greetings from Brasil....</em>

Let's solve this 2nd degree equation.

6b² + 8b - 10 = 0       dividing all terms by 2

3b² + 4b - 5 = 0         applying the baskara formula

Δ = 4² - 4 · 3 · (- 5)

Δ = 76

b = (- 4 ± √76)/6      so

<h2>b' = (- 4 + √76)/6</h2><h2>b'' = (- 4 - √76)/6</h2>

On October 15, 2019, Jon purchased and placed in service a used car. The purchase price was $38,000. This was the only business
san4es73 [151]

Answer:

cost recovery deduction = $1520

Step-by-step explanation:

given data

purchase price = $38,000

used the car  business  = 80%

used the car  personal = 20%

solution

cost recovery limit are

cost recovery limit = asset value × statutory % × mid quater convention   ..........1

we know car which have 5 year MACRS convention and as per MACRS depreciated 20 % in 1st year

and here this car is use so no 1st year depreciation

so we use MACRS statutory % method

cost recovery limit = $38000 × 5%

cost recovery limit = $1900

we know maximum limit is $3160

so cost of recovery is $1900

so

cost recovery deduction is

cost recovery deduction = cost recovery limit - personal use

cost recovery deduction = $1900 - ( $1900 × 20% )

cost recovery deduction = $1520

How do you factor out 4v(squared) - 16v + 7?
Salsk061 [2.6K]
It is a square trinomial:
4v^2 - 16v + 7 = 0
lets multiply and divide all by 4, the square term coefficient:
(16v^2 - 16(4)v + 28)(1/4) = 0
(4v - 14)(4v - 2)<span>(1/4) = 0
</span>factor 1/4
(4v - 14)(4v - 2)(1/2)<span>(1/2)</span> = 0
and divide each:
(2v - 7)(2v - 1) = 0
