Answer:

c

Step-by-step explanation:

You can find that 22-6=38-22=54-38=70-54=16

so the answer is c 16

Answer:  The correct opion is

(C) 16.

Step-by-step explanation:  Given that the values in the following table represent a linear function.

x:       1,     2,    3,     4,    5

y:       6,    22,  38,  54,  70.  

We are to find the common difference of the associated arithmetic sequence.

If y = f(x) is the given function, then we see that

f(1) = 6,  f(2) = 22,  f(3) = 38,  f(4) = 54 and f(5) = 70.

So, the common difference of the associated arithmetic sequence is given by

[tex]f(2)-f(1)=22-6=16,\\\\f(3)-f(2)=38-22=16,\\\\f(4)-f(3)=54-38=16,\\\\f(5)-f(4)=70-54=16,~~~\cdots.[/tex]

Thus, the required common difference of the associated arithmetic sequence is 16.

Option (C) is CORRECT.

Answer:

The surface area of the pyramid is 0.6625 inches²

Step-by-step explanation:

* Lets explain how to find the surface area of the square pyramid

- The square pyramid has 5 faces

- A square base

- Four triangular faces

- Its surface area is the sum of the areas of the five faces

- Area of the square = L × L , where L is the length of its sides

- Area of the triangle = 1/2 × b × h , where b is the length of its base

 and h is the length of its height

∵ The length of the side of the square is 0.25 inches

∴ Area of the base = 0.25 × 0.25 = 0.0625 inches²

∵ The length of the base of the triangle is 0.25 inches and the length

  of its height is 1.2 inches

∴ The area of its triangular face = 1/2 × 0.25 × 1.2 = 0.15 inches²

∵ The surface area of the pyramid = the sum of the areas of the 5 faces

∵ The area of the four triangular faces are equal

∴ The surface area = 0.0625 + (4 × 0.15) = 0.0625 + 0.6

∴ The surface area = 0.6625 inches²

* The surface area of the pyramid is 0.6625 inches²

Answer:

i think the answer is 7776

for two dice its 6x6 36 then 36×6 216 then 216×6 1296 then 1296×6 7776

Answer: 7776 possible outcomes

Step-by-step explanation:

You know that each dice has 6 possible results.

1, 2, 3, 4 , 5 , 6

Then, if you throw 2 dice, the possible results are 6(for the first one)*6(for the second one) = 6*6 = 36

then, as you add another die, you add another 6 to that equation, this means that for 5 dice we have

combinations = 6*6*6*6*6 = 6^5 = 7776

But in this situation most of the numbers can be repeated, for example, then number 6, can be made from (1 + 1 + 1 + 1 + 2), (1 + 2 + 1 + 1 + 1), (1 + 1 + 1 + 2 + 1 +1)

etc, this means that the die that rolls a 2 can change, but the end result of the addition is the same, in this case the total range of possible values is the amount of dice times the biggest value minus the amount of dice times the smallest value:

5*6 - 5*1 = 30 - 5 = 25 possible results

So you have 7776 combinations that give a only 25 possible results (a number between 5 and 30)

Answer:

-3± √5

Step-by-step explanation:

It is given that,

m² + 6m = -4

Points to remember

Solution of a quadratic equation ax² + bx + c = 0

x = [-b ± v(b² - 4ac)]/2a

To find the solution of given equation

m² + 6m = -4

⇒ m² + 6m  + 4 = 0

Here a = 1, b = 6 and c = 4

m =  [-b ± v(b² - 4ac)]/2a

  =  [-6 ± √(6² - 4*1*4)]/2*1

  = [-6 ± √(36 - 16)]/2

  = [-6 ± √20]/2

  = [-6 ± 2√5]/2

 = -3± √5

Answer:

u + v = <7 , 1>

║u + v║ ≅ 7

Step-by-step explanation:

* Lets explain how to solve the problem

- We can add two vector by adding their parts

∵ The vector u is <-4 , 7>

∵ The vector v is <11, -6>

∴ The sum of u and v = <-4 , 7> + <11 , -6>

∴ u + v = <-4 + 11 , 7 + -6> = <7 , 1>

∴ The sum u and v is <7 , 1>

* u + v = <7 , 1>

- The magnitude of the resultant vector = √(x² + y²)

∵ x = 7 and y = 1

∵ ║u + v║ means the magnitude of the sum

∴ The magnitude of the resultant vector = √(7² + 1²)

∴ The magnitude of the resultant vector = √(49 + 1) = √50

∴ The magnitude of the resultant vector = √50 = 7.071

* ║u + v║ ≅ 7

Answer:

4x+5y-34=0

Step-by-step explanation:

The slope-intercept form of a line is y=mx+b where m is the slope and b is the y-intercept.

My goal is to put in in this form first.  Then I will aim to put it in general form, ax+by+c=0.

So let's give it a go:

m is the change of y over the change of x.

To compute this I'm going to line my points up and subtract vertically, then put 2nd difference over 1st difference.  Like this:

( 1 , 6)

-(6 , 2)

----------

-5   4

So the slope is 4/-5 or -4/5.

So m=-4/5.

Now we are going to find b given y=mx+b and m=-4/5 and we have a point (x,y)=(1,6) [didn't matter what point you chose here].

6=-4/5 (1)+b

6=-4/5    +b

Add 4/5 on both sides:

6+4/5=b

30/5+4/5=b

34/5=b

So the y-intercept is 34/5.

The equation in slope-intercept form is:

y=-4/5 x + 34/5.

In general form, it is sometimes the goal to make all of your coefficients integers so let's do that.  To get rid of the fractions, I'm going to multiply both sides by 5.  This clears the 5's that were on bottom since 5/5=1.

5y=-4x+34

Now add 4x on both sides:

4x+5y=34   This is standard form.

Subtract 34 on both sides:

4x+5y-34=0

Answer:

14

Step-by-step explanation:

Assuming the die is 6 sided, there are only 6 possible rolls she can get. And assuming that this is a perfect world where probability is perfect, she will roll each number 14 times, because 84/6 is 14.

Final answer:

Kayla can expect to roll a number 3 approximately 14 times out of 84 rolls of a fair six-sided die, since each roll has a 1 in 6 chance of landing on any given number.

Explanation:

When Kayla rolls a die 84 times, she can expect to roll a 3 in a proportion equal to the probability of rolling a 3 on a single die. A fair six-sided die has a 1 in 6 chance of landing on any given number, including the number 3. Since each roll of the die is independent, we can calculate the expected frequency of rolling a 3 by multiplying the total number of rolls by the probability of rolling a 3.

The calculation is straightforward:

Therefore, Kayla can expect to roll a 3 approximately 14 times in 84 rolls.

Answer:

[tex]t=280\ minutes[/tex]

Step-by-step explanation:

Let's call "v" the speed of the commercial airplane and call "t" at the travel time of the commercial plane

The distance in kilometers of the trip is: 1730 km

Then we know that:

[tex]vt=1730[/tex]

Then for the jet we have that the speed is:

[tex]2v[/tex]

The flight time for the jet is:

[tex]t-140[/tex]

Therefore:

[tex](2v)(t-140) = 1730[/tex]

Substituting the first equation in the second we have to:

[tex](2*\frac{1730}{t})(t-140) = 1730[/tex]

[tex](\frac{3460}{t})(t-140) = 1730[/tex]

[tex]3460-\frac{484400}{t} = 1730[/tex]

Now solve for t

[tex]\frac{484400}{t} = 3460 - 1730[/tex]

[tex]\frac{484400}{t} =1730[/tex]

[tex]\frac{t}{484400} =\frac{1}{1730}[/tex]

[tex]t=\frac{484400}{1730}[/tex]

[tex]t=280\ minutes[/tex]

Answer:

In this quadratic equation,

I found these values by looking at the coefficient of [tex]x^2[/tex] and [tex]x[/tex]. Then I took the constant for the value of c.

Substitute the corresponding values into the formula for finding the discriminant.

Simplify this expression.

The answer for part A is [tex]\boxed{0}[/tex]

The discriminant tells us how many real solutions a quadratic equation has. If the discriminant is

Since the discriminant is 0, there is one real root so that means that the first option is correct.

The answer for part B is [tex]\boxed {\text{There is one real root with a multiplicity of 2.}}[/tex]

Answer:

A: 0  

B: There is one real root with a multiplicity of 2 .  

Step-by-step explanation:

Given a quadratic equation:

 [tex]ax^2+bx+c=0[/tex]

You can find the Discriminant with this formula:

[tex]D=b^2-4ac[/tex]

In this case you have the following quadratic equation:

[tex]x^2+2x+1=0 [/tex]

Where:

[tex]a=1\\b=2\\c=1[/tex]

Therefore, when you substitute these values into the formula, you get that the discriminant is this:

[tex]D=(2)^2-4(1)(1)\\\\D=0[/tex]

Since [tex]D=0[/tex], the quadratic equation has one real root with a multiplicity of 2 .

Answer:

z stays the same

Step-by-step explanation:

From the statements

z ∝ x and z ∝ 1/y

Combining both proportions

z ∝ x/y

z = k * (x/y)

The above equation defines the relationship between x,y and z

k is the proportionality constant.

Lets say that x and y are doubled

Then

z = k * (2x/2y)

2 in the numerator and denominator will be cancelled out

z = k * (x/y)

Therefore we can conclude that z will stay the same if x and y are doubled ..

Answer:

z stays the same

Step-by-step explanation:

We have been given that z varies directly with x and inversely with y.

Thus, we have the equation

[tex]z=\frac{kx}{y}...(i)[/tex]

Here k is constant of proportionality.

Now, x and y both are doubled, thus, the equation becomes

[tex]z=\frac{k(2x)}{2y}[/tex]

Cancel 2 from numerator and denominator

[tex]z=\frac{kx}{y}[/tex]

This is same as equation (i)

Hence, we can conclude that z remains same.

first option is correct.

Answer:

D

Step-by-step explanation:

To find the critical values , that is the zeros

Solve the quadratic

x² - x - 20 = 0 ← in standard form

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 1)

The factors are - 5 and + 4, since

- 5 × 4 = - 20 and - 5 + 4 = - 1, hence

(x - 5)(x + 4) = 0

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 4 = 0 ⇒ x = - 4

Thus the critical values are - 4, 5 → D

Answer:

D. -4, 5

Step-by-step explanation:

x² - x - 20 factorised = (x - 5) (x + 4)

In order to get the answers, you have to make each bracket equal zero.

(x - 5) = x = 5

(x + 4) = x = -4

The crucial numbers are -4 and 5.

Answer:

y=-6x+3

Step-by-step explanation:

Answer:

y=-6x+3

Step-by-step explanation:

because the slope will always have the X and in the middle you can put them together to get your answer

Answer:

A

Step-by-step explanation:

Given the 2 equations

y = x² - 4x + 8 → (1)

y = 2x + 3 → (2)

Since both express y in terms of x we can equate the left sides, that is

x² - 4x + 8 = 2x + 3 ( subtract 2x + 3 from both sides )

x² - 6x + 5 = 0 ← in standard form

(x - 1)(x - 5) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 5 = 0 ⇒ x = 5

Substitute these values into (2) for corresponding values of y

x = 1 : y = (2 × 1) + 3 = 2 + 3 = 5 ⇒ (1, 5)

x = 5 : y = (2 × 5) + 3 = 10 + 3 = 13 ⇒ (5, 13)

Solutions are (1, 5) and (5, 13)

Answer:

A. [tex](1,5)[/tex] and [tex](5,13)[/tex]

Step-by-step explanation:

We have been given a system of equations. We are asked to find the solution of our given system.

[tex]\left \{ {{y=x^2-4x+8}\atop {y=2x+3}} \right.[/tex]

Equate both equations:

[tex]x^2-4x+8=2x+3[/tex]

[tex]x^2-4x-2x+8-3=2x-2x+3-3[/tex]

[tex]x^2-6x+5=0[/tex]

Split the middle term:

[tex]x^2-5x-x+5=0[/tex]

[tex]x(x-5)-1(x-5)=0[/tex]

[tex](x-5)(x-1)=0[/tex]

Use zero product property:

[tex](x-5)=0\text{ (or) }(x-1)=0[/tex]

[tex]x=5\text{ (or) }x=1[/tex]

Now, we will substitute both values of x, in our given equation to solve for y.

[tex]y=2x+3[/tex]

[tex]y=2(1)+3[/tex]

[tex]y=2+3[/tex]

[tex]y=5[/tex]

One solution: [tex](1,5)[/tex]

[tex]y=2x+3[/tex]

[tex]y=2(5)+3[/tex]

[tex]y=10+3[/tex]

[tex]y=13[/tex]

Mode: 3 because it appears the most

Answer:

A. Mean = $41900

B. Median = $37000

C. Mode = $37000

Step-by-step explanation:

A. Mean

Here

n=40

Mean = Sum of values/n

[tex]Mean = \frac{(3)(18000)+(3)(22000)+(3)(25000)+(5)(34000)+(17)(37000)+(2)(45000)+52000+(5)(80000)+140000}{40}\\=\frac{54000+66000+75000+170000+629000+90000+52000+400000+140000}{40} \\=\frac{1676000}{40}\\=41900[/tex]

Mean = $41900

B. Median:

As the number of salaries is even,

the median will be mean of middle two terms

[tex]Median= \frac{1}{2}(\frac{n}{2}th\ term+ \frac{n+2}{2}th\ term)\\=  \frac{1}{2}(\frac{40}{2}th\ term+ \frac{40+2}{2}th\ term)\\=\frac{1}{2} (20th + 21st)}\\[/tex]

The 20th and 21st term will be 37000

So their mean will be same

So,

Median = $37000

C. Mode

Mode is the value which occurs most of the time in data.

the occurrence of 37000 is highest in the given data.

So,

Mode = $37000 ..

Answer:

90 degree clockwise rotation about (0,0).

Step-by-step explanation:

That would be a clockwise rotation of 90 degrees about the origin (0,0).

The rotation that maps point K(8,-6) to K(-6,-8) is a counterclockwise rotation of 90 degrees about the point (0,0).

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.

Here,
To find the rotation that maps point K(8,-6) to K(-6,-8), we can use the following steps,

Plot the points K(8,-6) and K(-6,-8) on a coordinate plane.

Since point K(8,-6) is being mapped to point K(-6,-8), the rotation must be counterclockwise. As rotation about the origin with angle 90 gives the transformation equation,
(x, y) ⇒ (y, -x)

Therefore, the rotation that maps point K(8,-6) to K(-6,-8) is a counterclockwise rotation of 90 degrees about the point (0,0).

Final answer:

To determine if one triangle is a dilation of another, ratios of corresponding sides must be compared and set up as proportions to see if they are equivalent. When the proportions are equivalent, it indicates a consistent scale factor, confirming a dilation.

Explanation:

To determine if one triangle is a dilation of the other, we compare the ratios of corresponding sides from each triangle. A dilation occurs when all sides of one triangle are in proportion with the sides of a second triangle by the same scale factor. For example, if one triangle has sides of length 3, 4, and 5, and the second triangle has sides of length 6, 8, and 10, then the ratios of the corresponding sides (3/6, 4/8, 5/10) all simplify to 1/2, indicating that the second triangle is a dilation of the first.

To use ratios to determine if one triangle is a dilation of another, you need to set up proportions. For instance, we can express the ratios of corresponding lengths as fractions, and then set each of these ratios equal to the unit scale to form proportions. If the lengths of the triangles are given as 1 inch to 50 inches and 0.5 inches to 5 inches, we can set up the proportion 1/50 = 0.5/5 to show that they are equivalent.

In problems like this, proper notation and maintaining consistency across corresponding dimensions (e.g., width to width and length to length) is essential for accurate comparison.
