The polynomial that is prime is given by Option C: [tex]10x^2 - 4x +3x +6[/tex]

Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.

(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)

Checking all the listed polynomials for them being prime or not:

Rewriting it as:

[tex]x^3+3x^2+2x+6 = x^2(x+3) + 2(x+3) = (x^2 + 2)(x+3)[/tex]

shows that this polynomial has factors. Thus, it isn't prime polynomial

Rewriting it as:

[tex]x^3 + 3x^2 -2x -6 = x^2(x+3) -2(x+3) = (x^2-2)(x+3)[/tex]

shows that this polynomial has factors. Thus, it isn't prime polynomial

We can rewrite it as:

[tex]10x^2 -4x + 3x -6 = 10x^2 -x -6 = f(x) \: \rm (say)[/tex]

This polynomial is prime polynomial as it is irreducible in terms of polynomials having their coefficients as integers.

Case 4: [tex]10x^2 -10x + 6x - 6[/tex]

It can be factored as:

[tex]10x(x-1) + 6(x-1) = (x-1)(10x-6)[/tex]

This is not a prime polynomial.

Thus, the polynomial that is prime is given by Option C: [tex]10x^2 - 4x +3x +6[/tex]

A city starts with a population of 500,000 people in 2007. Its population declines according to the equation

P(t) = 500,000e -0.099t

where P is the population in t years later. Approximately when will the population be half the initial amount?

Answer:

2014

Step-by-step explanation:

Given the exponential growth function :

P(t) = 500,000e^-0.099t

Where P is population in t years later

When the population will 1/2 the initial amount

1/2 the initial amount = 1/2 * 500,000 = 250,000

P(t) = 250,000

250,000 = 500000e^-0.099t

250,000/500000 = e^-0.099t

In(0.5) = - 0.099t

t = −0.69314 / - 0.099

t = 7.0014

t = 7

Year which population = 500,000 = 2007

Hence, half the population will be attained on (2007 + 7) = 2014

After 7 years population of the city will be half of the initial amount.

Population function:

[tex]P(t) = 500000 e^{-0.099t}[/tex]

Initial population means population at t=0

P(0) = 500000

Half of initial population = 250000

So, we need to calculate the time t when the population will be half of the initial amount.

[tex]250000= 500000 e^{-0.099t}\\\\e^{-0.099t} = \frac{1}{2}[/tex]

Taking log both sides

-0.099t (log e)= log (1/2)

The logarithm of e is 1 when considering the base of the log as e.

So, -0.099 t= -0.693

t=7

Therefore, After 7 years population of the city will be half of the initial amount.

Base on the similarity principle of triangles, the distance d across the lake as shown is 90 ft.

Two triangles are similar if they are only difference in size but have the same shape.

In similar triangles, corresponding sides are always in the same ratio.

Therefore, let's create a proportion from the triangles since they are similar.

40 / d = 20 / 45

cross multiply

45 × 40 = 20d

1800 = 20d

divide both sides by 20

1800 / 20 = 20d / 20

d = 90 ft

16 x 2 = 32

One-third of 48 is 16. So if Felix collected one-third and Andrea collected two-thirds, then Felix had 16 signatures and Andrea had 32 signatures.

Answer:

16

Step-by-step explanation:

1/3 of 48 is 16. if Felix collected 1/3 and Andrea collected 2/3, then Felix got 16 signatures

Answer:

Step-by-step explanation:

They all give 8r so that is not the distinguishing characteristic.

The first one in column A gives

12r + t - 4r + 6t

12r - 4r + t + 6t

8r + 7t  

This is the third one in column B

2nd one in Column A

12r + 2t - (4r + 10t)               Remove the brackets

12r + 2t - 4r - 10t                  Pay close attention to 10t becoming -10t. The minus sign effects both terms inside the brackets.

12t - 4t + 2t - 10t                  Combine

8r - 8t                                   Now take out the common factor (8)

8(r - t)                                    That's the top one in column B

3rd one in column A

12(r + t) - 6(r +t) + 4(r + t) - 2(r+t)    They all have r+t so r + t is a common factor)

(r+t) [12 - 6 + 4 - 2]                          Combine

(r + t ) [ 8 ]

This is the second one in  column B

The trick here is to look out for common factors. Don't remove the brackets. But it takes a bit of practice before you know that

Answer:

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

Step-by-step explanation:

You have to subtract

Let o = the polynomial

So you know 2x^3 - x^2 + 4x + 5 - o = x^3 + 2x - 9

Now you do 2x^3 - x^3 = x^3

then you -x^2 + answer = 0

you need to cancel it out

to cancel, you found out that it is x^2

Now you need to make from 4x to 2x.

To do that, you do 4x - 2x and you get 2x

Lastly you need to change -5 to 9. To do that you add -4.

Now since it is subtraction you have to distribute

2x^3 - x^2 + 4x - 5 -(x^3 - x^2 + 2x + 4)

= 2x^3 - x^2 + 4x + 5 - x^3 + x^2 -2x -4

= x^3 -2x + 9
