Answer: (B) -2, (E) 1, (F) 2

<u>Step-by-step explanation:</u>

x³ - x² - 4x + 4

= x²(x - 1) - 4(x - 1)

= (x² - 4) (x - 1)

= (x - 2)(x + 2)(x - 1)

Set each factor equal to zero to find the roots:

x - 2 = 0 x + 2 = 0 x - 1 = 0

x = 2 x = -2 x = 1

It's a quadratic equation in disguise. If you let $y=x^{-1}$ , then $y^2=x^{-2}$ , and we can rewrite the equation as

$5y^2-17y+6=0$

Solve for $y$ however you like; we get $y=\dfrac25$ and $y=3$ .

But we want to solve for $x$ , so we have

$y=x^{-1}=\dfrac25\implies x=\dfrac52$

$y=x^{-1}=3\implies x=\dfrac13$

Sunset, inc., has a book value of equity of $14,865. long-term debt is $8,675. net working capital, other than cash, is $2,315.

juin [17]

Balance sheet equation states that:

Assets, A = Liabilities, L + Equity, E => A=L+E

In the current case,
L = Long term debt + Current liabilities = $8,675+$1,865 = $10,540
E = $14,865

Therefore,
A = 14,865 +10,540 = $25,405

Now,
Current assets (excluding cash) = current liabilities+Net working capital, other than cash = $1,865+$2,315 = $4,180

Additionally,
A = Fixed assets+Current assets (excluding cash) + Cash

Therefore,
Cash = 25,405-20,660-4,180 = $565

Uhhh what is 2+2-2+2

Ierofanga [76]

Its 4 because 2+2 is 4 and then you're subtracting 2 and then adding 2 again so its 4

Harry church borrowed 17,500.00 at 6.5% exact interest. He had to pay back a maturity value of 17,873.97 to pay off the loan. Wh

Answer:the term of the loan is approximately 4 months

Step-by-step explanation:

The term of the loan means the period for which the loan was given.

We would apply the formula for simple interest which is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

P = 17500

R = 6.5%

I = total amount paid - principal

I = 17,873.97 - 17,500.00 = 373.97

Therefore

373.97 = (17500 × 6.5 × T)/100

373.97 = 1137.5T

T = 373.97/1137.5

T = 0.32 years

Converting to months, it becomes

0.32 × 12 = 3.84

Approximately 4 months.
