Answer:

Options B, C, and D.

Step-by-step explanation:

The first graph is a parabola. Since it opens downwards, it means the leading coefficient is negative.

The third graph is also a parabola. Since it opens upwards, it means it has a positive leading coefficient.

The second and fourth graphs represents a polynomial with an odd degree. Since both polynomial goes rises on the left and keeps rising on the right, their leading coefficients are positive.

The correct options are:

B, C , and D

Answer: graph b and graph c and graph D

Answer:

Volume=2.2*10^10  km^3

Step-by-step explanation:

Given

Diameter of moon=d=3476 km

The formula for the volume of sphere is:

V=4/3 πr^3

As it can be clearly seen that the formula uses radius, and we are given diameter. So we have to find the radius first

So,

radius=r=d/2

=3476/2

=1738 km

Now putting the value of r and pi in the formula:

V=4/3*3.14*(1738)^3

=12.56/3* 5249879272

= 21979494552.106

Rounded off to two significant digits:

Volume=2.2*10^10  km^3

Answer:

[tex]V=2.2\ x\ 10^{10} km^3[/tex]

Step-by-step explanation:

The formula to calculate the volume of a sphere is:

[tex]V=\frac{4}{3}\pi r^3[/tex]

Where r is the radius of the sphere.

In this case we do not know the radius of the sphere, but we know the diameter.

By definition the diameter of a sphere is equal to twice the radius. This is:

[tex]d = 2r[/tex]

[tex]r = \frac{d}{2}[/tex]

In this case d= 3,476 km

So

[tex]r = \frac{3,476}{2}[/tex]

[tex]r = 1738\ km[/tex]

Finally

[tex]V=\frac{4}{3}\pi (1738)^3[/tex]

[tex]V=2.20\ x\ 10^{10} km^3[/tex]

What is AD? There is no picture...

Final answer:

The length of AD is calculated using the given formula, which is a proportion involving the length of AC and the variables a, c, and d. One must plug in the values for these variables and solve the equation to find the length of AD.

Explanation:

To find the length of AD, we use the given formula which indicates a proportional relationship between the lengths on a line segment. The formula involves variables that define the lengths of specific segments of the line, as well as the ratios between them. In this case, the formula is (Length AD) = (Length AC) × (a-d)/(a-c). Here's a step-by-step explanation:

This formula can be used to calculate the length of a line segment extending beyond the segment AC or that lies between points A and C, depending on the values of the variables involved.

y= x^2+20x+21

( x+3)(x+7)

or (x+7)(x+3)

Doesn't matter which one comes first

(x+3)(x+7) Answer

(x+7)(x+3) Answer

Answer:

( x + 7 ) ( x + 3 )

Solutions are -7 , -3

Step-by-step explanation:

x² + 10 x + 21

x ( x + 3 ) + 7 ( x + 3 ) = 0

( x + 7 ) ( x + 3 )

Factors = 3 , 7

Sum = 21

Product = 10

Answer:

That is correct.

Step-by-step explanation:

2 times 10=20

4 times 1=4

5 times 0.1=0.5

8 times 0.01=0.08

20+4+0.5+0.08=24.58

That is correct.

Oh now I see. Yes that is correct

So this is what I got before, in the other question you asked, and the expanded form on the paper is the same thing as this. The way I wrote it is just another version, both are correct:

20.00 + 4.00 + 00.50 + 00.08

(2 x 10) + (4 x 1) + (5 x 0.1) + (8 x 0.01)

Multiply all the numbers together in each parentheses set and you'll get the same thing as the other problem I answered!

In the first set of parentheses (2 x 10) when solved is equal to 20

20.00 + 4.00 + 00.50 + 00.08

In the second set of parentheses (4 x 1) when solved is equal to 4

20.00 + 4.00 + 00.50 + 00.08

In the third set of parentheses (5 x 0.1) when solved is equal to .5

20.00 + 4.00 + 00.50 + 00.08

In the fourth set of parentheses (8 x 0.01) when solved is equal to 00.08

20.00 + 4.00 + 00.50 + 00.08

Hope this was way more helpful!

ANSWER

[tex]{i}^{20} + 1 =2[/tex]

EXPLANATION

The given expression is;

Recall that, in complex numbers

[tex] {i}^{2} = - 1[/tex]

We use this identity to simplify the given expression:

[tex]{i}^{20} + 1 =( {i}^{2})^{10} + 1[/tex]

This implies that:

[tex]{i}^{20} + 1 =( - 1)^{10} + 1[/tex]

[tex]{i}^{20} + 1 =1+ 1[/tex]

[tex]{i}^{20} + 1 =2[/tex]

Answer:

• mathematical: y ≤ 52

• reasonable: 0 ≤ y ≤ 52

Step-by-step explanation:

The reasonable range is the set of heights between the maximum height and the ground (y=0).

___

The maximum height is about 44.51 meters, so values between that and 52 meters are not in the reasonable range. A maximum height of 52 meters requires an initial velocity of about 15.4 m/s.

Answer:

It's 35

Step-by-step explanation:

I took a test that had this question on it and it said this was the right answer.

Different combination to pulls out 4 coins each time from 7coins is equals to 35.

" Combination is defined as the selection of the objects from the given set where arrangement of order does not matter."

Formula used

[tex]nC_{r} = \frac{n!}{(n-r)!r!}[/tex]

According to the question,

Total number of coins 'n' = 7

Number of coins pulls out each time 'r' = 4

Substitute the value in the formula to get different combination,

[tex]7C_{4} = \frac{7!}{(7-4)!4!}[/tex]

      [tex]= \frac{(7)(6)(5)(4!)}{(3!)(4!)} \\\\=\frac{(7)(6)(5)}{(3)(2)(1)}\\\\=(7)(5)\\\\=35[/tex]

Hence, different combination to pulls out 4 coins each time from 7coins is equals to 35.

Answer: 3/28

Step-by-step explanation:

Answer:

x =  2.5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the gradient and c the y- intercept )

here m = - 2 and c = 5, so

y = - 2x + 5 ← equation of line

To find the x- intercept let y = 0, that is

- 2x + 5 = 0 ( subtract 5 from both sides )

- 2x = - 5 ( divide both sides by - 2 )

x =  2.5 ← x- intercept ⇒ (2.5, 0 )

Answer:

445.2 square cm

Step-by-step explanation:

The surface area consists of  area of two bases and area of three leteral faces. Each lateral face is a rectangle with length of 23 cm and width of 6 cm.

The area of rectangle is

[tex]A_{rectangle}=\text{length}\times\text{width}[/tex]

So,

[tex]A_{rectangle}=23\times 6=138\ cm^2[/tex]

The area of base is given as [tex]15.6\ cm^2[/tex]

Thus, the surface area is

Mean is the average so just add up all the numbers in your data set and divide by the total for numbers that there are.

Ex. (5, 7, 8, 9)

5+7+8+9=29

29/4=7.25

7.25 is the Mean.

Median is the number that is directly in the middle so just count inwards from each side after you ordered your data set. If you get two numbers just add them both and divide by two.

Step-by-step explanation:

To solve for e, it must be alone on one side of the equation

Your equation is:

e/2 = 3

To get rid of the divided by 2, you multiply both sides by 2 since multiplication is the opposite of divison.

So:

e/2 = 3

[Multiply both sides by 2]

e = 6

Final answer:

Discrimination, particularly in the labor market as demonstrated by disparities in job callbacks and opportunities based on race, gender, and disability, represents a systemic issue that persists despite legal protections against such practices.

Explanation:

Discrimination is the unfair treatment of individuals or groups based on characteristics such as race, gender, or religion. One of the most common forms of discrimination occurs in the labor market, where individuals may face disparities in job opportunities and wages. An example of this is how studies have shown that individuals with white sounding names receive more callbacks for interviews than African-American names, indicating racial discrimination. Furthermore, women and those disclosing a disability also face significant hurdles in the job market, highlighting gender discrimination and disability discrimination. Despite the existence of laws against discrimination in the United States and global conventions from the United Nations aimed at eliminating all forms of discrimination, these practices unfortunately persist. Institutional discrimination extends beyond individual acts of prejudice to include systemic issues such as white privilege, which confers benefits upon the dominant group often without their conscious acknowledgment.

The explicit rule for the given sequence is to add 3.5 to each previous term.

The given sequence is:

10.5, 14, 17.5, 21, 24.5, ...

The explicit rule for this sequence is that each term is obtained by adding 3.5 to the previous term. So, the nth term of the sequence can be represented by the formula:

Tn = Tn-1 + 3.5

where Tn is the nth term of the sequence and Tn-1 is the previous term.

Final answer:

The explicit rule for the sequence 10.5, 14, 17.5, 21, 24.5, ... is a_n = 7 + 3.5n.

Explanation:

The sequence given is 10.5, 14, 17.5, 21, 24.5, ... and we need to find an explicit rule for this sequence in simplified form. Observing the sequence, we see that each term is increasing by 3.5. Therefore, the common difference in this arithmetic sequence is 3.5. We can express the nth term of the sequence using the formula:

an = a1 + (n - 1)d, where a1 is the first term and d is the common difference.

Since the first term a1 is 10.5 and d is 3.5, the rule for the nth term is:

which simplifies to an = 7 + 3.5n.

2x2x2

Take the first two numbers: 2 x 2; this equals 4.

Take that number and multiply by the next number (2): 4 x 2 = 8

Hope this helps! :)

The value of 2 x 2 x 2 using the multiplication operation gives the result 8.

The expression 2 x 2 x 2 represents the multiplication of three 2's together.

To simplify the expression, perform the multiplication operation:

= 2 x 2 x 2

= 4 x 2

= 8

Therefore, 2 x 2 x 2 is equal to 8.

In other words, multiplying three 2's together results in the value of 8.

This can be visualized as multiplying 2 by 2 to get 4 and then multiplying that result by 2 again to obtain 8.

Answer:

option C is the correct answer

Step-by-step explanation:

System A:                                                  System B:

-x - 2y = 7    ........(1)                               -x - 2y = 7    .......(3)  

5x - 6y = -3  ........(2)                                  -16y= 32  ........(4)

Solution for system A: ( -3, -2)

For option A

Multiply the first equation by 3

3(- x - 2y) = 3(7)         ⇒     - 3x - 6y = 21 ........... (5)

Add equation 2 and 5

  5x - 6y = -3

- 3x - 6y = 21

  2x -12y = 18   ⇒  2( x - 6y ) = 2( 9 )    ⇒   x - 6y = 9

Option A is not equal to equation in system B so now we check option B.

 For option B

Multiply the first equation by -5

-5(- x - 2y) = -5(7)         ⇒    5x + 10y = -35 ........... (6)

Add equation 2 and 6

  5x - 6y = -3

  5x + 10y = -35

  10x + 4y = -38   ⇒   2( 5x + 2y ) = 2(-19)    ⇒  5x + 2y = -19

Option B is not equal to equation in system B so now we check option C.

For option C

Multiply the first equation by 5            

5(- x - 2y) = 5(7)         ⇒   - 5x - 10y = 35 ........... (7)

Add equation 2 and 7

  5x - 6y = -3

- 5x - 10y = 35

    0 - 16y = 32   ⇒   -16y = 32

Option C is equal to equation in system b so now we check if the solution to system B is same as system A.  

Solution to system B:

First, we find value of y from equation 4:

-16y = 32   ⇒    y = [tex]\frac{32}{-16}[/tex]   ⇒    y = -2

Now, we put value of y in equation 3 to find value of x:

-x - 2y = 7  ⇒  -x - 2(-2) = 7   ⇒  -x + 4 = 7   ⇒  -x = 7 - 4  ⇒  -x = 3

multiply both sides by -1

-1 × (-x) = -1 × (3)       ⇒     x = -3

Solution of system B = (-3, -2)

Solution of system B is the same as system A, so option C is correct.
