Answer/Step-by-step explanation:

Based on the factor theorem, a polynomial, x - a, is said to be a factor of another polynomial, f(x), if an only if f(a) = 0.

Using this theorem, let's determine whether each of the given first polynomial, is a factor of the second polynomial.

1. x - 1; x² + 2x + 5

By the factor theorem, x - 1 will be a factor of f(x) = x² + 2x + 5, if and only if f(1) = 0.

f(1) = 1² + 2(1) + 5

= 1 + 2 + 5

= 8

Since f(1) ≠ 0, therefore the first polynomial, x - 1, is NOT a factor of the second polynomial, x² + 2x + 5.

2. x + 1; x³ - x - 2

By the factor theorem, x + 1 will be a factor of f(x) = x³ - x - 2, if and only if f(-1) = 0.

f(1) = -1³ - (-1) - 2

= -1 + 1 - 2

= -2

Since f(-1) ≠ 0, therefore the first polynomial, x + 1, is NOT a factor of the second polynomial, x³ - x - 2.

3. x - 4; 2x³ - 9x² + 9x - 20

By the factor theorem, x - 4 will be a factor of f(x) = 2x³ - 9x² + 9x - 20, if and only if f(4) = 0.

f(4) = 2(4)³ - 9(4)² + 9(4) - 20

= 128 - 144 + 36 - 20

= 0

Since f(4) = 0, therefore the first polynomial, x + 4, is a factor of the second polynomial, 2x³ - 9x² + 9x - 20.

4. a - 1; a³ - 2a² + a - 2

By the factor theorem, a - 1 will be a factor of f(a) = a³ - 2a² + a - 2, if and only if f(1) = 0.

f(1) = 1³ - 2(1)² + 1 - 2

= 1 - 2 + 1 - 2

= -2

Since f(1) ≠ 0, therefore the first polynomial, a - 1, is NOT a factor of the second polynomial, a³ - 2a² + a - 2.

5. y + 3; 2y³ + y² - 13y + 6

By the factor theorem, y + 3 will be a factor of f(y) = 2y³ + y² - 13y + 6, if and only if f(-3) = 0.

f(-3) = 2(-3)³ + (-3)² - 13(-3) + 6

= -54 + 9 + 39 + 6

= 0

Since f(-3) = 0, therefore the first polynomial, y + 3, is a factor of the second polynomial, 2y³ + y² - 13y + 6.

Answer:

I think you need to know the value of X to get this answer.

Step-by-step explanation:

We want to find a polynomial

f(x) = a x³ + b x² + c x + d

such that the roots of f are x = -3, x = -1, and x = 4, and f(x) takes on a value of -24 when x = -2.

The factor theorem for polynomials tells us that we can factorize f(x) as

a x³ + b x² + c x + d = a (x + 3) (x + 1) (x - 4)

Expand the right side:

(x + 3) (x + 1) (x - 4) = x³ - 13x - 12

So we have

a x³ + b x² + c x + d = a x³ - 13a x - 12a

In order for both sides to be equal, the coefficients of both polynomials on terms of the same degree must be equal. This means

a = a (of course)

b = 0 (there is no x² term on the right)

c = -13a

d = -12a

We also have that f (-2) = -24, which means

f (-2) = a (-2 + 3) (-2 + 1) (-2 - 4)

-24 = 6a

a = -4

which in turn tells us that c = 52 and d = 48.

So we found

f(x) = -4x³ + 52x + 48

I would say 2880 sorry if am wrong

Step-by-step explanation:

6000*48=288,000 then divide by 100 because percent means 100. 288,000/100= 2,880. hope this helps can I get brainlist and add effort before you come to look for anwer.

Answer:

d. Reject the claim that mean is 40 MPG when it is actually 40 MPG.

Step-by-step explanation:

The type 1 error could be said to have been made if the null hypothesis is erroneously rejected.

In the scenario above :

The null hypothesis (H0) : mean = 40

Hence, if the Null hypothesis defined above is rejected when in fact the hypothesis that the mean miles per gallon is actually 40.

On the other hand, the type 2 error occurs when a null which is false is not rejected.

Hence, when a true null is rejected, a type 1 error is committed. Similarly, when a false null isn't rejected, then a type 2 error has been committed.

Answer:

See below :D

Step-by-step explanation:

Well, 20% is simply 20/100. By reducing it would go down to 2/10... try to reduce 2/10 in its lowest terms! You can do it, I believe in you :D

Another way is converting it to a decimal:

0.20

Which is another way of saying 0.2

0.2 = 2/10

2/10 is not reduced in its lowest terms, but I'm sure you can figure out the rest. Good luck and ask if you need more details in the works or if you can't figure it out! I'll be here.

Answer:

The answer is below

Step-by-step explanation:

a) A linear function shows the relationship between variables. A linear equation is in the form: y = mx + b, where m is the rate of change, b is the value of y when x = 0, y is the dependent variable and x is an independent variable.

Let U represent the number of umbrellas and p the price of the umbrella. At $10 the number of umbrella sold is 18000, it can be represented as (10, 18000) i.e. (p, U)

At $16 the number of umbrella sold is 9000, it can be represented as (16, 9000).

The linear function is determined using:

[tex]U-U_1=\frac{U_2-U_1}{p_2-p_1}(p-p_1)[/tex]

Given (10, 18000) and (16, 9000):

[tex]U-U_1=\frac{U_2-U_1}{p_2-p_1}(p-p_1)\\\\U-18000=\frac{9000-18000}{16-10}(p-10)\\\\U-18000=-1500(p-10)\\\\U-18000=-1500p+15000\\\\U=-1500p+15000+18000\\\\U=-1500p+33000\\\\U(p)=-1500p+33000[/tex]

b) At p = $20, The number of umbrella is:

U(20) = -1500(20)+33000

U(20) = 3000 umbrella

Answer:

Option 3: 12 is the correct answer.

Step-by-step explanation:

Given functions are:

[tex]f(x) = 16x-30\\g(x) = 14x-6[/tex]

In order to find the value of x on which (f-g)(x) will be zero, first of all we have to find (f-g)(x) and then equate it equal to zero to find the value of  that will make (f-g)(x)

So,

[tex](f-g)(x) = f(x) - g(x)\\= (16x-30)-(14x-6)\\=16x-30-14x+6\\= 2x-24[/tex]

Now to find the value of x on which (f-g)(x) will be zero, putting (f-g)(x) = 0

[tex](f-g)(x) = 0\\2x-24 = 0[/tex]

Adding 24 on both sides

[tex]2x-24+24 = 0+24\\2x = 24[/tex]

Dividing both sides by 2

[tex]\frac{2x}{2} = \frac{24}{2}\\x = 12[/tex]

For x=12, (f-g)(x) will be zero.

Hence,

Option 3: 12 is the correct answer.

Given the value of the original quantity and the value of the new quantity, the percent​age increase is 50%.

Percent​ increase is aimply the amount of increase from the initial value to the new value in terms of 100 parts of the initial value.

It is expressed as;

C = ((x₂ - x₁) / x₁)100%

Where x₁ is initial value and x₂ is new value

Given the data in the question;

We substitute the given values into the expression above.

C = ((x₂ - x₁) / x₁)100%

C = ((15 - 10) / 10)100%

C = (5/10)100%

C = 0.5 × 100%

C = 50%

Therefore, given the value of the original quantity and the value of the new quantity, the percent​age increase is 50%.

Answer: answer is -7

Step-by-step explanation:

Step-by-step explanation:

Original Equation;

1x=7(x+6)

Multiply the 7 by the x and 6

1x=7x+42

Group like terms

1x-7x=42

-6x=42(Divide both sides by -6)

x= -7 (We have -7 because 42 can be divided by 6 7 times)

Answer:

a coffee is one dollar

Step-by-step explanation:

if he spends the same amount of momey each day, lets say a coffee is a dollar. the first day he spends 2.50 on a newspaper plus 1 dollar on a coffee equaling 3.50 dollars. if he purchased a 1.50 dollar newspaper and two coffees, two coffees would equal two dollars plus 1.50 equaling 3.50 dollars. that answer equals the same amount that he spent on monday.
