Answer:

The median is 5.5

Answer:

The interval notation for the domain is [tex][\frac{23}{3},\infty ][/tex].

Step-by-step explanation:

Consider the provided information.

It is given that [tex]\:f\left(x\right)=\sqrt{3x-2},\:\text{ and }\:g\left(x\right)=x-7[/tex]

We need to find the value of [tex]f\left(g\left(x\right)\right)[/tex].

Put the value of g(x) in  [tex]f\left(g\left(x\right)\right)[/tex].

[tex]f\left(g\left(x\right)\right)=f(x-7)[/tex]  ....(1)

Now, put x=x-7 in [tex]\:f\left(x\right)=\sqrt{3x-2}[/tex]

[tex]\:f\left(x-7\right)= \sqrt{3(x-7)-2}[/tex]

[tex]\:f\left(x-7\right)= \sqrt{3x-21-2}[/tex]

[tex]\:f\left(x-7\right)= \sqrt{3x-23}[/tex]

From equation 1.

[tex]f\left(g\left(x\right)\right)=\:f\left(x-7\right)= \sqrt{3x-23}[/tex]

The domain of the function is the set of input values for which a function is defined.

Here, the value of [tex]3x-23[/tex] should be greater or equal to 0 as the square root of a negative number is not real.

Domain= [tex]3x-23\geq0[/tex]

[tex]x\geq\frac{23}{3}[/tex]

The value of x is all real number greater than [tex]\frac{23}{3}[/tex].

Hence, the interval notation for the domain is [tex][\frac{23}{3},\infty ][/tex].

Step-by-step explanation:

Remember the Difference of Squares:

a² - b² = (a + b)(a - b)

Therefore (√20 - √3)(√20 + √3)

= (√20)² - (√3)² = 20 - 3 = 17. (C)

Each angle  = 60 o Explanation: The two alternate interior angles provided are: ( 2 x + 10 ) o  and, ( 3 x − 15 ) o A pair of alternate interior angles as per property ,have equal values. ( 2 x + 10 ) o = ( 3 x − 15 ) o ( 10 + 15 ) o = 3 x − 2 x 25 o = x So, angle 1:  ( 2 x + 10 ) o = 2 × 25 + 10 = 60 o  angle 2:  ( 3 x − 15 ) o = 3 × 25 − 15 = 60 o

Step-by-step explanation:

i did a cm to feet calcu-lator

have good day

The correct answer is 4 feet 17 inches is 160.5 c.m.

The process to convert cm to feet is simple. 1 cm. is equal to 0.025 feet. So you must multiple the unit by 0.025.

Given:

1 feet = 38.48 cm.

1 cm. = 0.025 feet.

160.5 cm = (0.025/1) * 160.5

160.5 cm = 4.1709 feet  

4.1709 feet  

4.1709 feet  = 4 feet + 1709 inches.

We can 4.1709 feet which is equal to 4 feet 17 inches.

Therefore, 160.5 cm is equal to  4 feet 17 inches.

Answer:

   -135/14

Step-by-step explanation:

There are an infinite number of rational numbers between any pair of numbers you name. These two number have the decimal values ...

  -67/7 = -9 4/7 = -9.571428... (repeating)

  -78/8 = -9 3/4 = -9.75

So, numbers like -9.6 = -48/5, or -9.7 = -97/10 are rational numbers that lie in the range you specified.

If you like, you can convert these numbers to ones with a common denominator (56).

 -67/7 = -536/56

 -78/8 = -546/56

These limits suggest several possible rational numbers with 56 as a denominator: -540/56 = -135/14, for example.

Step-by-step explanation:

We have Angle ZWD = Angle DWN.

=> 5v - 7 = 4v + 8, v = 15.

Therefore x = Angle ZWD = 5(15) - 7 = 68.

Answer:

384.7 cubic inches

Step-by-step explanation:

formula to find Volume of a Cylinder:  

V = π · r² · h

7 is the diameter, so r = 3.5

V = π (3.5)² · 10

V = π (12.25)(10)

V = π · 122.5

V ≈ 384.7 in³

Answer:

a) 94°

Step-by-step explanation:

shape is a 5-sided polygon, known as a pentagon

number of degrees inside can be found by taking the number of sides (5), deducting 2 (3) and then multiplying by 180°.

Therefore there are 540° altogether.

add all like terms for all five angles:  24x - 12 = 540

                                                             24x = 552

                                                               x = 23

m∡P = 4(23) = 2

         = 92 + 2

Answer:

24+15k=

Step-by-step explanation:

First we multiply the 6 to the numbers in the parentheses, so 4x6=24, and 2x6=12, making the expression look like this: 24+12k+3k=

Then we combine like terms, which would be the number that are attached to 'k'. So that makes the expression look like this: 24+15k=

I'm not sure what else you're suppose to do to create a new expression since there's nothing on the other side of the equal sign, but that's as much as the expression will simplify.

Answer:

Head bands: 18.58 inches of fabric

Wrist bands : 8.51 inches of fabric

Step-by-step explanation:

Jillian is making accessories for the soccer team.

For head bands

She uses 761.78 inches of fabric on headbands for 39 players and 2 coaches.

The total number of people = 39 player + 2 coaches = 41 people

Hence:

41 persons = 761.78 inches of fabric

1 person = x

Cross Multiply

41 × x = 761.78 × 1

x = 761.78/48

x = 18.58 inches

For wristbands

She also uses 331.89 inches of fabric on wristbands for just the players.

Number of players = 39 players

Hence:

39 players = 331.89 inches

1 players = x inches

Cross Multiply

39 × x = 1 × 331.89 inches

x = 331.89 inches/39

x = 8.51 inches

Therefore:

18.58 inches of fabric was used for head bands and 8.51 inches of fabrics was used for wristbands.

Answer:

Area of rectangle = [tex]\mathbf{x^2-4x}[/tex]

Perimeter of rectangle = [tex]\mathbf{4x-8}[/tex]

Step-by-step explanation:

We are given:

Length of rectangle = x

Width of rectangle = x-4

We are not given if we want to find area of rectangle or perimeter of rectangle.

So, I will be finding both

Area of rectangle

The formula used is: [tex]Area\: of\: rectangle=Length \times Width[/tex]

Putting values and finding area

[tex]Area\: of\: rectangle=Length \times Width\\Area\: of\: rectangle=x \times (x-4)\\Area\: of\: rectangle=x^2-4x[/tex]

So, we get area of rectangle = [tex]\mathbf{x^2-4x}[/tex]

Perimeter of rectangle

The formula used is: [tex]Perimeter \: of\: rectangle=2(Length+ Width)[/tex]

Putting values and finding perimeter

[tex]Perimeter \: of\: rectangle=2(Length+ Width)\\Perimeter \: of\: rectangle=2(x+ x-4)\\Perimeter \: of\: rectangle=2(2x-4)\\Perimeter \: of\: rectangle=4x-8[/tex]

So, we get perimeter of rectangle = [tex]\mathbf{4x-8}[/tex]

Answer: A. [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]

Step-by-step explanation:

According to the recipe,

For 2 batches, 3 cups of flour required.

One batch has 15 mix rolls

Then 2 batches will have 2 (15) = 30 rolls

Each person gets one roll, so 3 cups of flour is required for 30 people.

The quanity of flour is proportional to the number of people.

Let x be the quantity of flour required for 12 people.

By proportion,

[tex]\dfrac{\text{Quantity of flour}}{\text{Quanity of person}}=\dfrac{3}{30}=\dfrac{x}{12}[/tex]

Required proportion: [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]

The correct option is A. [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]

Answer:

Step-by-step explanation:

One point can be the y-intercept. We can see that the y-intercept is (0,-3). -3 is the value of y when x = 0. The next point can be when x = 2. If we plug that in the equation, we get the point (2,-6).

Plotting these two points will graph the equation.

The graph is given below.

Some of the coordinates on the graph are (0, -3, (1, -4.5), and (2, -6).

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

y = (-3/2)x - 3

The coordinates from the given equation are:

When x = 0,

y = - 3

(0, -3)

When x = 1,

y = -3/2  - 3 = (-3 - 6)/2 = -9/2 = -4.5

(1, -4.5)

When x = 2,

y = -3 - 3 = -6

(2, -6)

Now,

The graph of the equation is given below.

Thus,

The graph is given below.
