You synthetic division to find P(3) for p(x)=x^4-6x^3-4x^2-6x-2

klio [65]

By the polynomial remainder theorem, the remainder upon dividing $p(x)$ by $x-3$ will be the value of $p(3)$ .

... | 1 ... -6 ... -4 ... -6 .... -2
3. | .. ... 3 ... -9 ... -39 .. -135
--------------------------------------
... | 1 ... -3 ... -13 . -45 .. -137

So you have

$\dfrac{x^4-6x^3-4x^2-6x-2}{x-3}=x^3-3x^2-13x-45-\dfrac{137}{x-3}$

which means $p(3)=-137$ .

Avicenna, a major insurance company, offers five-year life insurance policies to 65-year-olds. If the holder of one of these pol

ki77a [65]

Answer:

Avicenna can expect to lose money from offering these policies. In the long run, they should expect to lose ___33__ dollars on each policy sold

Step-by-step explanation:

Given :

The amount the company Avicenna must pay to the shareholder if the person die before 70 years = $ 26,500

The value of each policy = $497

It is given that there is a 2% chance that people will die before 70 years and 98% chance that people will live till the age 70.

The expected policy to be sold= policy nominal + chances of death

= 497 + [98% (no pay) + 2% (pay)]

= 497 + [98%(0) + 2%(-26500)]

(The negative sign shows that money goes out of the company)

= 497 - 2% (26500)

= 497 - 530

=33

Therefore the company loses 33 dollar on each policy sold in the long run.

An amount of R351 is made up with 114 coins (R2 coins and R5 coins only). How many R2 coins are there? How many R5 coin are ther

lisabon 2012 [21]

Answer:

Step-by-step explanation:

For this, you have to make two equations;

One that calculates the amount of coins

and one that calculates the amount of R

I'm going to set

R2 = x

R5 = y

To make this a bit easier to look at

So to do the number of coins, you want to do this:

x + y = 114

This is saying that the total amount of R2 coins plus the total amount of R5 coins will add up to 114

Then, you want to calculate the worth of them.

2(x) + 5(y) = 351

This is saying that for ever R2 coin there is, it will increase the total by 2, and every R5, it will increase the total by 5. When you add these together, it will come out to 351.

Then you have to solve the system of equations:

x + y = 114

2x + 5y = 351

-2 * (x + y = 114)

2x + 5y = 351

-2x + -2y = -228

2x + 5y = 351

3y = 123

y = 41

Since y is the amount of R5 coins, we know we have 41 R5 coins.

So the answer is

4 0
