Answer:

f(x) = x³ - 4x² + x + 6

Step-by-step explanation:

The polynomial function f has zeros at -1, 2, and 3.

So, the least degree of the polynomial will be 3{As it has three roots}.

Then, if the function is of x variable then (x + 1), (x - 2) and (x - 3) will be the factors of the polynomial.

Therefore, we can write  

f(x) = (x + 1)(x - 2)(x - 3)

⇒ f(x) = (x + 1)(x² - 5x + 6)

⇒ f(x) = x³ - 5x² + 6x + x² - 5x + 6

⇒ f(x) = x³ - 4x² + x + 6  

Hence, this is the polynomial with least degree having rational coefficients and with leading coefficient of 1 and the zeroes -1, 2, 3. (Answer)

Proportion which can be used to represent equivalency of 3 feet in 1 yard and 12 feet in 4 yard is 3 : 1 : : 12 : 4

Given that

There are 3 feet in one yard  

And there are 12 feet in 4 yard  

Number of feet in one yard = 3 that is feet  : yard = 3 : 1  

Number of feet in 4 yards = 12 that is feet : yard = 12 : 4  

And 3 feet in 1 yard is equivalent to 12 feet in 4 yards means

[tex]\frac{3}{1}=\frac{12}{4}[/tex]

That is 3 : 1 : : 12 : 4

A proportion is statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a : b = c : d

Answer:

c = 793/28 , d = -358/7

Step-by-step explanation:

Solve the following system:

{4 c + 2 d = 11 | (equation 1)

(7 d)/2 = -179 | (equation 2)

Multiply equation 2 by 2:

{4 c + 2 d = 11 | (equation 1)

0 c+7 d = -358 | (equation 2)

Divide equation 2 by 7:

{4 c + 2 d = 11 | (equation 1)

0 c+d = -358/7 | (equation 2)

Subtract 2 × (equation 2) from equation 1:

{4 c+0 d = 793/7 | (equation 1)

0 c+d = -358/7 | (equation 2)

Divide equation 1 by 4:

{c+0 d = 793/28 | (equation 1)

0 c+d = -358/7 | (equation 2)

Collect results:

The conclusion about the relationship between the number of cars sold and the high temperature is "The high temperature and the number of cars sold may have a negative correlation, but one may not cause the other". Option D.

What can you conclude about the relationship between the number of cars sold and the high temperature?

Correlation in scatter plot indicates the strength and direction of a relationship between two variables. A positive correlation means that as one variable increases, the other also increases, while a negative correlation means that as one variable increases, the other decreases.

Therefore, from the scatter plot, it can be concluded that high temperature and the number of cars sold may have a negative correlation, but one may not cause the other.

Step-by-step explanation:

Answer:

Perimeter = (20 + 2x) mm.

Step-by-step explanation:

The octopus pupil has length 20 mm and the expression for its area is given by (20x - 200) square mm.

If the width of the octopus pupil is w, then 20w = 20x - 200

⇒ w = (x - 10) mm.

Therefore, the expression for its perimeter is 2(Length  + Width) = 2 ( 20 + x - 10) = 2( 10 + x) = (20 + 2x) mm. (Answer)

The expression that represents the perimeter of the octopus pupil is 20 millimeters.

To find the expression that represents the perimeter of the octopus pupil, you need to know the length and area of the pupil. The length is given as 20 millimeters, and the area is represented by the expression (20x-200) square millimeters. The perimeter of a shape is the sum of all its side lengths.

So, for the octopus pupil, the perimeter can be found by adding up the lengths of all its sides. Since the shape is not specified, we'll assume it's a regular shape with all sides equal in length.

To find the expression for the perimeter, we need to know the number of sides. If we assume it has n sides, then each side has a length of 20/n millimeters. Therefore, the perimeter expression would be 20/n multiplied by n, which simplifies to 20 millimeters.

Answer:

The number of math problems Annabelle solved = 5 problems

The number of pages Annabelle read=  20 pages

Step-by-step explanation:

Given:

Time taken for Annabelle to solve one problem =3 minutes

Time taken for Annabelle to read one page =2 minutes

Total time taken by Annabelle to complete her homework= 55 minutes

To find:

Total Number of problems solved by Annabelle=?

Total Number of pages read by Annabelle=?

Solution:

Let the number of problem solved be x

Let the number of pages read be y

It is given that the number pages read is 4 times the number of problem solved

So number of pages read y= 4x

Now time taken to solve x problems =  time taken to solve one problem X total number of problem

=>[tex]3\times x[/tex]

=>[tex]3x[/tex]

Similarly,

Time taken to read 4x pages= total number of pages read X  time taken to read one problem

=>[tex](4x)\times 2[/tex]

=>[tex]2(4x)[/tex]  

Now we know that

Time taken to solve x problems + Time taken to read 4x pages= 55  minutes

3x + (4x)2=55

3x+8x=55

11x=55 [tex]x=\frac{55}{11}[/tex]

x=5

Answer:

The given function[tex]R(x) = x - x + x^2  - x[/tex] has 2 x -intercepts.

Step-by-step explanation:

Here, the given polynomial function is :

[tex]R(x) = x - x + x^2  - x\\\implies R(x) = x^2 - x[/tex]

or,  [tex]y  = x^2 - x[/tex] ............  (1)

X- intercept is the point in the graph of R(x), where the coordinate y = 0.

Now, substituting the value of y  =  0 in (1) find all x - intercepts:

[tex]y  =  0   \implies x^2 - x = 0\\x(x-1)  =0\\\implies(x-0)(x-1) = 0[/tex]

⇒ Either x = 0 ,         or x - 1 = 0 ⇒  x = 1

⇒The given function has two x intercepts at x  = 0 and x = +1

Hence, the given function[tex]R(x) = x - x + x^2  - x[/tex] has 2 x -intercepts.

OPTION A and OPTION C

Step-by-step explanation:

OPTION A:

[tex]$ \frac{1}{5}x - 10 $[/tex] and [tex]$ \frac{1}{5}(x - 50) $[/tex]

Consider [tex]$ \frac{1}{5}(x - 50) = \frac{x}{5} - \frac{50}{5} $[/tex]

This is equal to [tex]$ \frac{1}{5}x - 10 $[/tex].

This is exactly the first expression. So, we say both expressions are equivalent.

OPTION B:

[tex]$ \frac{1}{3} x - 6 $[/tex] and [tex]$ - \frac{1}{3}(3x  + 18) $[/tex]

Distributing [tex]$ -\frac{1}{3} $[/tex] to [tex]$ (3x + 18) $[/tex] we get:

[tex]$ \frac{-x}{3} + \frac{-18}{3} $[/tex]

⇒ [tex]$ -x - 6[/tex]

This is not equivalent to the first expression.

OPTION C:

[tex]$ \frac{1}{2}x + 8 $[/tex] and [tex]$ \frac{1}{2}(x + 16) $[/tex]

[tex]$ \frac{1}{2}(x + 16) = \frac{x}{2} + \frac{16}{2} $[/tex]

[tex]$ \implies \frac{1}{2}x + 8 $[/tex]

This is exactly the first expression. So, we say the expressions are equal.

We apply similar techniques to OPTION D and OPTION E. Note that the expressions are not equal in both the options.

Answer:

There is no solution for x.

Step-by-step explanation:

We are given that [tex]\sin (\cos x) = 1[/tex] and we have to solve for x.

Let us assume that [tex]\cos x = \theta[/tex] then [tex]\sin \theta = 1[/tex] ........ (1)

Now, we know that for any value of x the value of cos x lies between 1 to - 1.

Hence, [tex]1 \geq  \cos x \geq  - 1[/tex]  for all x.

⇒ [tex]1 \geq  \theta \geq  - 1[/tex]

Now, for [tex]1 \geq  \theta \geq  - 1[/tex], the value of [tex]\sin \theta[/tex] can never be equal to 1.

Answer:

The number is -4.

Step-by-step explanation:

Let the number be n.

Given:

Max adds 7 to a number.

hence it is given as n+7

Multiply's the sum by -4 the result is 3 times the same number.

Hence the equation can be written as;

[tex]-4(n+7)=3n[/tex]

Now Solving the above equation to find value of n we get;

[tex]-4(n+7)=3n\\-4n-28=3n\\-4n-3n=28\\-7n=28\\n=\frac{28}{7}=-4[/tex]

The value of n is -4.

Now when we add 7 to number -4 we get answer as 3.

And when the sum is multiplied by -4 we get answer -12.

Also 3 times of number is equal to 3 multiplied by -4 we get answer as -12.

Hence when the sum is multiplied by -4  it is equal to 3 times of same number.

Hence from above we can say that the number is -4.

Final answer:

The number that satisfies Max's operation of adding 7 to a number and then multiplying by -4 to get 3 times the same number is -4.

Explanation:

Max adds 7 to a number n, then multiplies the sum by -4, and the result is 3 times the same number n. To find the number n, we first write down the equation that represents this situation:

-4(n + 7) = 3n

Next, we solve for n:

Distribute -4 inside the parenthesis: -4n - 28 = 3n

Move all n terms to one side: -4n - 3n = 28

Combine like terms: -7n = 28

Divide both sides by -7 to isolate n: n = -4

The number n that satisfies this equation is -4.

The statement that is true about the given table is "The situation can be modelled by an exponential decay function with a percent change of -10%".

Consider the function:

y= a(1 ± r)ˣ

where m is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

Given that An event management company purchases a new van. The value of the van, x years after the purchase, is shown in the table.

Now, if the rate of decay and the initial price of the van can be found by substituting the value of x and y in the equation as shown below.

For the first column from the table, when the value of x and y is 0 and 20,000, respectively.

y= a(1 + r)ˣ

20,000 = a(1 + r)⁰

20,000 = a (1)

a = 20,000

For the second column from the table, when the value of x and y is 1 and 18,000, respectively. Also, the value of a=20,000.

y= a(1 + r)ˣ

18,000 = 20,000(1 + r)¹

18,000/ 20,000 = 1 + r

0.9 = 1 + r

0.9 - 1 = r

-0.1 = r

r = -0.1 = -10%

Hence, the statement that is true about the given table is "The situation can be modelled by an exponential decay function with a percent change of -10%".
