20 points!!! Which of the following functions represent the graph of? Question and answers linked below, thank you!

Answer:

B) x² - 8x + 12

E) (x -4)² - 4

F) (x - 2)(x - 6)

Explanation:

As the graph opens upwards. The value of x² will be positive.

The x intercepts are (2, 0), (6, 0) determining (x -2)(x-6)

The (x - 4)² - 4 determines the vertex of x = 4, y = -4

When simplified:

⇒ (x -2)(x-6)

⇒ x² - 2x -6x + 12

⇒ x² - 8x + 12

Answer:

Always

Step-by-step explanation:

The alternate interiors are the orange pair and the green pair in between lines a and b. They've got symmetry! Rotating one of those lines 180 degrees won't change the picture or the angles of intersection, but it will flip one onto the other. Anyway, there's you answer above, if that's all you're looking for.

Let's consider first what equation we must use:

 ⇒ use Combination Formula ⇒ [tex]._{n} C_{r}=\frac{n!}{r!(n-r)!}[/tex]

      ⇒ where 'n'  is the total number of items and 'r'

      is the number of items to choose

Let's look at the problem:

Let's plug it in:

 [tex]\frac{18!}{4!*(18-4)!} =\frac{18!}{4!*14!} =\frac{18*17*16*15}{4*3*2*1} =18*17*2*5=3060[/tex]

Thus there are 3060 ways

Answer: 3060 ways

Hope that helps!

Answer:

es kunno.............................

Let's take this problem step-by-step:

Let's first set up some variables:

Let's examine the information given:

          ⇒ average child is 75 pounds

          ⇒ average adult is 150 pounds

                 ⇒ therefore: [tex]75c + 150a\leq 1500[/tex]

          ⇒ therefore: [tex]c + a \leq 14[/tex]

Let's graph the equations:

 [tex]75c+150a\leq 1500\\c+a\leq 14[/tex]

    ⇒ look at the image attached

The point at which the two graphs intersect:

  ⇒ is the solution that represents the amount of children and adults and

      their combine weight

With the horizontal axis being the # of children and vertical axis being the # of adults:

 ⇒ the solution is 8 children and 6 adults

Answer: 8 children and 6 adults

The verbal translation of p v q is:

A student is in math club OR debate club

pvq is true for a total of 28 students.

Given the table:

7                                           15

6      

If p represents a student from the maths club

If a represents a student from the debate club

The verbal translation of p v q is:

A student is in math club OR debate club

Hence, the total number of students based on pvq is 7 + 6 + 15= 28 students.

Answer:

79% of females are attending the class field trip

Step-by-step explanation:

Question Breakdown:

- Survey 271 students

- 121 males respond, 92 attending field trip

- 31 females not attending field trip

What percent of females are attending the class field trip?​

The two-way table or the class whether they are attending the field trip or not is attached below,

The table tells us

• Males who are not attending : 121 - 192 = 29

• Total females who responded : 271 - 121 = 150

• Females who are attending : 250 - 31 = 119

• Total students who are attending : 91 + 119 = 211

• Total students who are not attending : 29 +31 = 60

There are a total of 150 female students and 119 of them are attending the field trip

[tex]\frac{119}{150} = 0.79 x 100 = 79%[/tex]

Answer:

3.5x10^4 is 50 times larger than 7x10^2

Step-by-step explanation:

3.5x10^4 is 35,000 (move decimal 4 places to the right)

7x10^2 is 700 (7.0 move decimal 2 places to the right)

700x50=35,000 which shows that 35,000 is 50 times larger than 700

Answer:

2√6

Step-by-step explanation:

find the hypotenuse of the triangle thats 3 and 7

pythagorean

3 squared + 7 squared

16 + 49 = 57

√57 is the hypotenuse

√57 is also the base of the triangle that has side thats 9

pythagorean theorem

x squared + √57 squared = 9 squared

x^2 + 57 = 81

x^2 = 81 - 57

x^2 = 24

x = √24

x = √4 * √6

x = 2√6

Answer:

  C.  (1, -1/2)

Step-by-step explanation:

The midpoint of a line segment has coordinates that are the average of the end point coordinates.

__

  M = (A +B)/2 . . . . . . midpoint of segment between A(1, 4) and B(1, -5)

  M = ((1, 4) +(1, -5))/2 = (1 +1, 4 -5)/2 = (2, -1)/2

  M = (1, -1/2)

The midpoint of the vertical line segment is (1, -1/2).

_____

Additional comment

The midpoint will always be on the line segment. Since this line segment is vertical with x = 1, the x-coordinate of the midpoint must be 1.

The slope and the y intercept of the line on the graph is -1/4 and 1.

A straight line function is what can be written in the form of

y =mx +c

where m is the slope and c is the intercept on y axis.

The intercept on the y axis , c = 1

at x = 4 , y=0

and at x = 0, y =1

The slope can be calculated as

y = mx+1

0 = 4m +1

m = -1/4

Therefore the slope and the y intercept of the line on the graph is -1/4 and 1.

The system of exponential functions that can be used to determine the time for the profits to be the same is given by:

[tex]3000(0.985)^x = 1500(1.012)^x[/tex]

An exponential function is modeled by:

[tex]A(t) = A(0)(1 \pm r)^t[/tex]

In which:

For the first restaurant, we have that the parameters are given as follows:

A(0) = 3000, r = -0.015.

Hence the profit after x weeks is given by:

[tex]y_1(x) = 3000(0.985)^x[/tex]

For the second restaurant, we have that:
A(0) = 1500, r = 0.012.

Hence:

[tex]y_2(x) = 1500(1.012)^x[/tex]

Then they will be equal when:

[tex]y_1(x) = y_2(x)[/tex]

[tex]3000(0.985)^x = 1500(1.012)^x[/tex]
