Answer: p(x) = a (x-b)(x-c)(x-d)

Step-by-step explanation:

The first step is to determine the degree of the polynomial.

It shall depend totally on the linear factors given for the polynomial.

If there is one, it is a linear polynomial.

If there are 2, then it is a quadratic polynomial.

If there are three then it shall be a cubic polynomial.

Now let us assume that there are three linear factors.

We multiply those factors and write the polynomial.

If x-b, x-c & x-d are the factors we write

p(x) = (x-b)(x-c)(x-d)

But as we may have a leading coefficient so we write the polynomial as

Then we go on to expand this to get the polynomial in the standard form.

Answer with Step-by-step explanation:

First we find the degree of polynomial.

Consider two linear factors

(x-a) and (x-b)

Multiplying these two factors to get the polynomial.

[tex]p(x)=(x-a)(x-b)=x^2-(a+b)x+ab[/tex]

There are two linear factors .

Therefore, the degree of polynomial is 2 and the polynomial is quadratic.

Degree of polynomial=Number of linear factors

If the linear factors are three then the polynomial formed by multiplying theses factors .

Then, we get the polynomial of degree 3 and the polynomial is cubic polynomial.

It we have four linear factors.

After multiplying these four factors, we get a polynomial of degree 4.

The polynomial is bi quadratic.

Hence, the correct answer is:

             Option : a

             a.   5.6 amps

It is given that:

The current (I) in an electrical conductor varies inversely as the resistance (R) of the conductor.

This means that:

[tex]I\propto \dfrac{1}{R}[/tex]

Hence, we get the relation as:

[tex]\dfrac{I_1}{I_2}=\dfrac{R_2}{R_1}[/tex]

where [tex]R_1[/tex] is the resistance corresponding to the current [tex]I_1[/tex]

and  [tex]R_2[/tex] is the resistance corresponding to the current [tex]I_2[/tex]

We have:

[tex]I_1=6\ ,\ R_1=722\ ,\ R_2=768[/tex]

Hence, we get:

 [tex]\dfrac{6}{I_2}=\dfrac{768}{722}\\\\\\i.e.\\\\\\I_2=\dfrac{722\times 6}{768}\\\\\\I_2=5.6406\ amperes[/tex]

        Hence, the answer is:

A = 7.55

Step-by-step explanation:

Answer:

centre = (2, - 1), radius = 6

Step-by-step explanation:

Rearrange the equation by placing the x and y terms together and adding 31 to both sides

Given

x² + y² - 4x + 2y - 31 = 0, then

x² - 4x + y² + 2y = 31

Use the method of completing the square

add ( half the coefficient of the x/y term )² to both sides

x² + 2(- 2)x + 4 + y² + 2(1)y + 1 = 31 + 4 + 1

(x - 2)² + (y + 1)² = 36

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r the radius

compare to (x - 2)² + (y + 1)² = 36, then

centre = (2, - 1) and r = [tex]\sqrt{36}[/tex] = 6

The center of the circle is  (2, - 1) and the radius is 6 units.

The equation for a circle has the generic form x² + y² + 2gx + 2fy + c = 0.

The standard equation of a circle is x² + y² = r².

The polar form of the equation of the circle is (rcosθ)² + (rsinθ)² = p².

Given, The equation of a circle is x² + y² - 4x + 2y - 31 = 0.

We know, In x² + y² + 2gx + 2fy + c = 0, The center of the circle is,

(- g, - f) and radius is [tex]\sqrt{g^2 + f^2 - c[/tex].

Therefore, 2gx = - 4x and 2fy = 2y.

2g = - 4 and 2f = 2.

g = - 2 and f = 1.

- g = 2 and - f = - 1.

So, The center is (2, - 1).

And the radius is, [tex]\sqrt{2^2 + -1^2 + 31[/tex].

= [tex]\sqrt{4 + 1 + 31[/tex].

= [tex]\sqrt{36[/tex].

= 6 units.

The appropriate way to label the age intervals on the x-axis is:  Option: B

               B) 7−10; 11−14; 15−18; 19−22

            The rule for determining the number of intervals is:

Here we have 13 observations

and √(13)=3.6055≈4

Hence, we have a total of four intervals.

                 The width of each interval is calculated as:

                       i.e.   (22-7)/4=15/4=3.75≈4

We know that for classifying a class interval in a histogram the width of each of the interval must be equal.

A) 7−11; 11−14; 15−19; 20−22

In option: A--

the width of first interval is: 4

width of second interval is: 3

Width of third interval is: 4

Width of fourth interval is: 2

Hence, the width of each interval is not equal.

Hence, option: A is discarded.

C) 7−10; 10−15; 15−19; 19−22

In option: C--

the width of first interval is: 3

width of second interval is: 5

Width of third interval is: 4

Width of fourth interval is: 3

Hence, the width of each interval is not equal.

Hence, option: C is discarded.

D)  7−13; 15−19; 20−22

In option: D--

the width of first interval is: 6

width of second interval is: 4

Width of third interval is: 2

Hence, the width of each interval is not equal.

Hence, option: D is discarded.

B)  7−10; 11−14; 15−18; 19−22

There are a total of 4 intervals and also width of each interval is equal and equal to 4.

Answer:

x = - 5

Step-by-step explanation:

The line with equation x = - 2 is a vertical line parallel to the y- axis

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (- 5, 4) with x- coordinate - 5, thus

equation of parallel line is x = - 5

Answer:

Option B

Step-by-step explanation:

Given  

Two Data sets

Class A :{ 2, 5, 7, 6, 4, 3, 8, 7, 4, 5, 7, 6, 3, 5, 4, 2, 4, 6, 3, 5}

Class B : {3, 7, 6, 4, 3, 2, 4, 5, 6, 7, 2, 2, 2, 3, 4, 5, 2, 2, 5, 6}

In order to check the options we will have to find the mean and median of both data sets.

So for Class A:

Mean= x =(Sum of values)/(Number of values)

=96/20

=4.8

For median the data has to be arranged in ascending order, so

2, 2,3,3,3,4,4,4,4,5,5,5,5,6,6,6,7,7,7,8

Median will be the average of middle two values as the number of items are odd.

Median=(5+5)/2

=10/2

=5

Range = 8-2 = 6

For Class B:

Mean= x =(Sum of values)/(Number of values)

=80/20

=4

For median, arranging the values

2,2,2,2,2,2,3,3,3,4,4,4,5,5,5,6,6,6,7,7

Median=(4+4)/2

=8/2

=4

Range = 7-2 = 5

We get,

Mean of class A > Mean of Class B

Median of Class A > Median of Class B

Range of Class A > Range of Class B

We observe that only option B is correct for the given data sets..

the width is equal to a cm.

the length is twice the width, therefore the length is equal to 2a cm.

the height is twice the length, therefore the height is equal to 4a cm.  

the volume is equal to width times length times height which is equal to a * 2a * 4a which is equal to 8a^3 cubic cm.  

For Example:

let a = 5

then 2a = 10

then 4a = 20  

a is the width

2a is the length

4a is the height.  

the length is twice the width.

the height is twice the length  

the volume is equal to a * 2a * 4a which is equal to 8a^3 cubic cm.  

this is equivalent to 8 * 5^3 which is equal to 8 * 125 which is equal to 1000 cubic cm.  

5 * 10 * 20 = 50 * 20 = 1000 cubic cm.  

formula works and so is considered to be good.  

the volume is equal to 8a^3 cubic cm.

* hope you understand*

The volume of a rectangular solid where width equals a cm, length equals twice the width, and the height is twice the length is calculated to be 8a³ cubic cm.

Based on the question, we know that the width of the rectangular solid is a cm. Where the length equals twice the width, so it is 2a cm; likewise, the height, which is twice the length, turns out to be 4a cm. The equation for calculating the volume of a rectangular solid is width * length * height. Therefore, if we substitute the given values, we have a cm * 2a cm * 4a cm, which equals 8a³ cubic cm. As a result, the volume of this given rectangular solid is 8a³ cubic cm.

[tex]x\geq 3 \ and \ x+1 \geq 4[/tex]

The question in this problem is:

The sum of 2 consecutive integers is at most the difference between nine times the smaller and 5 times the larger. What are the numbers?

First of all, let's name the first variable [tex]x[/tex] which is the smaller number. Accordingly, the lager number will be [tex]x+1[/tex] given that those numbers are consecutive. On the other hand at most conveys the idea of an inequality, which is:

[tex]\leq \\ which \ means \ less \ than[/tex]

So:

1. The sum of 2 consecutive integers can be written as:

[tex]v+(v+1)[/tex]

2. Nine times the smaller and 5 times the larger can be written as:

[tex]9v-5(v+1)[/tex]

Finally, the whole statement:

The sum of 2 consecutive integers is at most the difference between nine times the smaller and 5 times the larger:

[tex]x+(x+1) \leq 9x-5(x+1) \\ \\ x+x+1\leq 9x-5x-5 \\ \\ 2x+1 \leq 4x-5 \\ \\ 6 \leq 2x \\ \\ [/tex]

[tex]x+(x+1) \leq 9x-5(x+1) \\ \\ x+x+1\leq 9x-5x-5 \\ \\ 2x+1 \leq 4x-5 \\ \\ 6 \leq 2x \\ \\ \frac{6}{2} \leq \frac{2x}{2} \\ \\ 3 \leq x \\ \\ x\geq 3 \\ \\ and \\ \\ x+1 \geq 4[/tex]

The two numbers are:

[tex]x\geq 3 \ and \ x+1 \geq 4[/tex]

Explanation:

This expression is a quadratic equation of the form at² + bt + c = 0, where the constants are a = 4.90, b = -14.3, and c = -20.0.

To solve for the missing value, we can rearrange the equation:

-4.5 + 4.4 + ____ = 0

Simplifying the equation, we get:

-4.5 + 4.4 + ____ = 0

-0.1 + ____ = 0
