B. 

It can first be factored by splitting to:

(x + 1)(x^2 +4)

And (x^2 + 4) splits to x +/- 2i

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

x^3+x^2+4x+4

We need to given the complete factorization of the above expression.

So, First we factorise the above expression.

x^3+x^2+4x+4\\\\=x^2(x+1)+4(x+1)\\\\=(x+1)(x^2+4)

Since factorization of x^2+4 would contain complex number.

so, it becomes,

x^2+4=(x+2i)(x-2i)

So, the complete factorisation would be (x+2i)(x-2i)(x+1).

Hence, Option 'B' is correct.

The CPU of a personal computer has a lifetime that is exponentially distributed with a mean lifetime of six years. a) What is th
amm1812

Answer: Our required probability is 0.39.

Step-by-step explanation:

Since we have given that

X be the exponentially distributed with mean life = 6 years

So, E[x]=6

\dfrac{1}{\lambda}=6\\\\\lambda=\dfrac{1}{6}

So, our cumulative distribution function would be

F(x)=1-e^{-\lambda x}

We need to find the probability that the CPU fails within 3 years.

P(X

Hence, our required probability is 0.39.

On the first day of the fiscal year, Shiller Company borrowed $85,000 by giving a seven-year, 7% installment note to Soros Bank.
Lera25 [3.4K]

Answer

A₁ - Journal entry at the time of issue of installment note for cash:

Bank A/c                              Dr           $85,000

To Notes Payable               Cr           $85,000

A₂– Journal entry at the time of first annual payment:

Notes Payable A/c           Dr           $9,822

Interest Expense A/c       Dr           $5,950

To Bank A/c                   Cr                            $15,772

Notes payable to be reported in balance sheet at the end of fiscal year:

Notes payable end balance = $85,000 - $9,822 = $75,178

Interest for 2nd year = $75,178 * 7% = $5,262

Installment amount for 2nd year = $15,772  

Principal repayment for 2nd year = $15,772 - $5,262 = $10,510

Therefore out of $75,178 notes payable, $10,510 is payable within 1 year.

There $10510 will be shown in balance sheet as current liabilities and

remaining $64,668 will be shown in balance sheet as long term liability.
