Answer:

32

Step-by-step explanation:

a^2+b^2=c^2

24^2+b^2=40^2

b^2=40^2-24^2

b^2=1600-576

      =1024

b=sqrt(1024)

 =32

Linkin Corporation is considering purchasing a new delivery truck. The truck has many advantages over the company’s current truc
Romashka [77]

Answer:

Payback is 7.3 years

NPV $3,099  

Step-by-step explanation:

The formula for payback period period=initial investment/annual cost savings

The initial investment is the amount of cash outflow that would be required to purchase the new delivery truck,which is $54,750,while on the other hand the  annual cost savings is $7,500

cash payback period=$54,750/$7,500=7.3 years

Ordinarily,the expected payback is 1/2 of 8 years=4 years.

The net present is the present worth of the future cost savings as well as the scrap value of the truck in year 8,calculated by multiplying the cash flows with the discounted factors for relevant years as below:

Years                 cash flow         DCF at 8%        Present values

0                      -$54,750            1                           -$54,750  

1-7 years            $7500             5.2064                  $39,048

8                        $34,800           0.54027               $18,801

NPV                                                                          $3,099  

Note that the  $34,800 =$7500+$27300

The year 1-7 factor is annuity factor for 8% 7 years

The points at x equals=​_______ and xequals=​_______ are the inflection points on the normal curve
uysha [10]
We know that the probability density function of a variable that is normally distributed is f(x) = 1/(σ√2π) * exp[1/2 (x – µ). Its inflection point is the point where f"(x) = 0.
Taking the first derivative, we get f'(x) = –(x–µ)/(σ³/√2π) exp[–(x–µ)²/(2σ²)] = –(x–µ) f(x)/σ².
The second derivative would be f"(x) = [ –(x–µ) f(x)/σ]' = –f(x)/σ² – (x–µ) f'(x)/σ² = –f(x)/σ² + (x-µ)² f(x)/σ⁴.
Setting this expression equal to zero, we get
–f(x)/σ² + (x-µ)² f(x)/σ⁴ = 0
Multiply both sides by σ⁴/f(x):
–σ² + (x-µ)² = 0
(x-µ)² = σ²
x-µ= + – σ
x = µ +– σ
So the answers are x = µ – σ and x = µ + σ.
