Evaluate the functions.

For this case we have:

By definition, a mathematical function is the correspondence or relation f of the elements of a set A with the elements of a set B. A function fulfills the condition of existence (all the elements of A are related to the elements of B) and with the condition of uniqueness (Each element of A is related to a single element of B).

That said, we can conclude that the relationship shown in the table defines a function of the form [tex]y = f (x)[/tex]

By definition, the domain of a function is represented by the input elements of it.

Thus, the domain is given by Domain: (m, n, p, q)

Answer:

Yes, Domain: (m, n, p, q)

a. m<5=40° (Given)

b. m<2=140° (Given)

c. <5 and <2 are supplementary angles

Because they add 180°: <5+<2=40°+140°=180°

d. <5 and <2 are same-side interior angles

You can see it in the graph

e. a // b

Because they are same-side interior angles and they are supplementary angles, the lines a and b must me parallels.

There are 8 sitcoms that can be recorded on the remaining tape.

To find out how many 30-minute sitcoms can be recorded on the remaining tape, we need to subtract the duration of the existing movie from the maximum capacity of the VHS tape. So, 360 minutes - 120 minutes = 240 minutes remaining. Since each sitcom is 30 minutes long, we can divide the remaining time by 30 to find out the number of sitcoms: 240 minutes ÷ 30 minutes = 8 sitcoms can be recorded on the remaining tape.

Answer:

Option A is correct.

Change in the y-values is 40 and the change in x-values is 1.

Step-by-step explanation:

Let x represents the time in minutes and y represents the temperature(in Fahrenheit).

Given two points on the line graph i.e,

[tex]A(x_1, y_1)= (2 , 150)[/tex]  and  [tex]B (x_2, y_2)= (3, 190)[/tex]

we have to find the change in the y-value and x-value on the graph:

Change in the x-values for the given points is;

[tex](x_2 - x_1)[/tex] = 3 - 2 = 1

Similarly,

Change in the y-values for the given points is;

[tex](y_2 - y_1)[/tex] = 190-150 =40.

Since, the slope or the rate of change of the given line graph is the ratio of the change in the y-value over the change in the x-value i.e, slope = 40.

Therefore, change in the y-values is 40 and the change in x-values is 1.

Answer:

Is it the subset of 1, or other numbers.

Step-by-step explanation:

please be more specific with the question so I can actually answer please, I would try to help but I don't know the question. If you update it It would be more helpful.

To list all subsets of a set, use binary representation to generate all possible combinations by including or excluding each element.

A subset is a collection of elements from a set. To list all subsets of a set, we can use the concept of binary representation. Each element in the set can be either included or excluded in a subset. By representing each element as a binary digit, we can generate all possible subsets.

For example, if we have a set {1, 2, 3}, we can represent it as 000, 001, 010, 011, 100, 101, 110, 111, where each digit represents whether the element should be included or not. The subsets are: { }, {1}, {2}, {1, 2}, {3}, {1, 3}, {2, 3}, {1, 2, 3}.

Solution

f(x) = -20[tex]x^{2}[/tex] +14x + 12 and g(x) = 5x - 6.

(f/g)(x) = [tex]\frac{f(x)}{g(y)}[/tex]

(f/g)(x) = [tex]\frac{-20x^{2}+14x +12 }{5x - 6}[/tex]

Step 1: Now we have to factorize the numerator.

f(x) = -20x^2 + 14x + 12

Factor out -2, we get

= -2 (10x^2 - 7x - 6)

Now we can factorize 10x^2 - 7x - 6                  

f(x) = -2(2x + 1) (5x - 6)

Step 2: Plug in the factors

(f/g)(x) = [tex]\frac{-2 (2x +1)(5x - 6)}{(5x - 6)}[/tex]

Step 3: Cancel out the common factor (5x - 6) from the numerator and the denominator, we get

(f/g)(x) = -2(2x +1) = -4x -2

Since -4x -2 is linear expression, the domain is all the real numbers.

Therefore, the answer is –4x – 2; all real numbers

118 book on each shelf 9440 divided by 80=118

Answer: There are 118 books on each shelf.

Step-by-step explanation:

Since we have given that

Number of non fiction books a library has = 9440

Number of shelves = 80

So, Number of books on each shelf would be

[tex]\dfrac{\text{Number of non fiction books}}{\text{Number of books on each shelf}}[/tex]

[tex]\dfrac{9440}{80}\\\\=118[/tex]

Hence, there are 118 books on each shelf.

It's a linear function. We need only two points to draw a graph.

We choose any values of x and calculate the value of y.

[tex]6x-2y=2\qquad|-6x\\\\-2y=-6x+2\qquad|:(-2)\\\\y=3x-1[/tex]

for x= 0 → y = 3(0) - 1 = 0 - 1 = -1 → (0, -1)

for x = 2 → y = 3(2) - 1 = 6 - 1 = 5 → (2, 5)

[tex]9x-3y=1\qquad|-9x\\\\-3y=-9x+1\qquad|:(-3)\\\\t=3x-\dfrac{1}{3}[/tex]

for x = 0 → y = 3(0) - 1/3 = 0 - 1/3 = -1/3 → (0, -1/3)

for x = 2 → y = 3(2) - 1/3 = 6 - 1/3 = 5 2/3 → (2, 5 2/3)

1 hour = 3600 seconds

Calculate feet per hour first:

3600 seconds / 3 = 1200

1200 x 20 feet = 24,000 feet in 1 hour

1 mile = 5280 feet

Calculate miles per hour:

24,000 / 5280 = 4.54 miles per hour.

Round the answer as needed.

[tex]LCM(180,\ 594)=\boxed{2}\cdot\boxed{3}\cdot\boxed{3}\cdot2\cdot3\cdot5\cdot11=5940\\\\GCF(180,\ 594)=\boxed{2}\cdot\boxed{3}\cdot\boxed{3}=18[/tex]

So, the ratio between the LCM of 180 and 594 and the GCF of 180 and 594 is [tex]\(990:1\)[/tex].

To find the ratio between the least common multiple (LCM) and the greatest common factor (GCF) of two numbers, we need to calculate both the LCM and the GCF first.

1. Calculate the LCM of 180 and 594:

  The prime factorization of 180 is [tex]\(2^2 \times 3^2 \times 5\)[/tex].

  The prime factorization of 594 is [tex]\(2 \times 3^3 \times 11\)[/tex].

  The LCM is the product of the highest power of each prime factor:

  LCM [tex]\(= 2^2 \times 3^3 \times 5 \times 11 = 5940\)[/tex].

2. Calculate the GCF of 180 and 594:

  The common factors of 180 and 594 are [tex]\(2 \times 3 = 6\)[/tex]  

  So, GCF [tex]\(= 6\)[/tex].

Now, let's find the ratio between the LCM and the GCF:

[tex]\[ \text{Ratio} = \frac{\text{LCM}}{\text{GCF}} = \frac{5940}{6} = 990 \][/tex]

Answer 4

Step-by-step explanation:

The number that, when raised to the 10th power and divided by the same number to the 7th power equals 27, is 3. This is resolved by simplifying the initial equation to realize that we are looking for the cube root of 27.

The question is asking for a number which, when raised to the 10th power and divided by the same number raised to the 7th power, equals 27. Let's denote the number as 'x'. The mathematical representation of this would be x10 / x7 = 27. Since x10 / x7 simplifies to x3, our equation becomes x3 = 27. Now if we solve this, the number 'x' equals the cube root of 27, which is 3.

Y intercept means the y-coordinate of the point where the graph crosses the y-axis.

Given equation is:

[tex]-2x+6y=5[/tex]

Let x be 0, as at the y-intercept point, the x-coordinate of that point is always 0.

[tex]-2(0)+6y=5[/tex]

[tex]6y=5[/tex]

y=[tex]\frac{5}{6}[/tex]

Slope-intercept form is y = mx + b

where m is the slope of the line and b is the y-intercept of the line {the number without a variable}

-2x+6y = 5

6y = 2x+5

y= [tex]\frac{2x}{6}+\frac{5}{6}[/tex]

Hence, slope is [tex]\frac{2}{6}or\frac{1}{3}[/tex]

In 4 days it will be 10 and 2/3

To find out how many inches elephant grass will grow in 4 days, multiply the daily growth rate by the number of days. The elephant grass will grow approximately 10 2/3 inches in 4 days.

To find out how many inches of elephant grass will grow in 4 days, we need to multiply the daily growth rate by the number of days. The daily growth rate is 2 2/3 inches. To convert this mixed number to an improper fraction, we multiply the whole number (2) by the denominator (3), which gives us 6. Adding the result to the numerator (2), we get 8. So the daily growth rate is 8/3 inches.

Next, we multiply the daily growth rate by the number of days: 8/3 * 4 = 32/3 inches. To simplify this fraction, we divide the numerator (32) by the denominator (3), which equals 10 with a remainder of 2. So the elephant grass will grow approximately 10 2/3 inches in 4 days.

28° and 152°

let the angle be x then supplementary angle = 3x + 68

Supplementary angles sum to 180° , hence

4x + 68 = 180 ( subtract 68 from both sides )

4x = 112 ( divide both sides by 4 )

x = [tex]\frac{112}{4}[/tex] = 28

He cuts the board into three parts.

The length of the first part = 23.5 cm

So, remaining length of the board = [tex]90 - 23.5[/tex] = 66.5 cm

Now, he cuts the second part.

The length of the second part = 33.3 cm

So, now remaining part of the board = [tex]66.5 -33.3[/tex] = 33.2 cm

Now, he cuts the third part of the board.

The length of the third part = 19.45 cm

Now, the remaining part of the board = [tex]33.2-19.45[/tex] = 13.75 cm
