Find the Missing Sides of the 30-60-90 special right angle.

F(x) = 4x & g(x) = 3x are the two functions which the (f o g)(x) was equal to "12x".

Legislation, a regulation, or a declaration that demonstrates the relationships between the independent and relationship between the factors (the dependent variable). Functions may be found everywhere in mathematics, and they are essential for building physical connections in the sciences.

The functions f(x) & g(x) are given, and the task is to determine (f o g) (x).

For the following two functions, (f o g)(x) was identical to "12x":

f(x) = 4x and g(x) = 3x.

Proof :

g(x) = 3x

(f o g)(x) = f(x = 3x) = 4(3x) = 12x

(f o g)(x) = 12x

Hence, f(x) = 4x or g(x) = 3x are the 2 type which the (f o g)(x) was equal to 12x.

Answer:

850 miles on 25 gallons

Step-by-step explanation:

Answer: 850 miles on 25 gallons is more efficient, meaning it covers a greater distance per gallon of fuel.

Step-by-step explanation:

The average rate of change of the temperature from 0 to 2 minutes is given as follows:

-6ºC per minute.

The average rate of change of a function is given by the change in the output divided by the change in the input.

The temperatures for this problem are given as follows:

Hence the change in the output is given as follows:

62 - 74 = -12ºC.

The change in the input is of:

Answer: -3/16

Step-by-step explanation:

When there is a negative exponent like x^-2 it equals 1/(x^2) the negative puts the number as a fraction so continuing...

-12(x^-2) (y^-2) can be rewritten as

-12 (1/x^2) (1/y^2) now we plug in x = -2 and y = 4

-12 (1/(-2^2) (1/(4^2)); -2^2 = 4 , 4^2 = 16

-12 (1/4) (1/16)

By rounding off, we can determine that Mike thought the difference would be 72 whereas it is actually 72.74.

When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number.

For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.

The crucial figures are preserved when numbers are rounded off.

Look at the next digit in the correct position to determine how to round a number; if it is less than 5, round down, and if it is 5 or more, round up.

So, Mike calculated 79 as 79.44 and 7 as 6.7, so he calculated the difference as follows:

79 - 7 = 72

Actual figures that differ are:

79.44 - 6.7 = 72.74

Therefore, by rounding off, we can determine that Mike thought the difference would be 72 whereas it is actually 72.74.

Answer:

0 < a < 6

or

(0, 6) in interval notation

Step-by-step explanation:

The area of the triangle is
[tex]Area \;A = \dfrac{1}{2}(base \cdot height)\\[/tex]

We are given base = 6 in, height = a and area A < 18 in²

Using the formula for area we get

[tex]A = (1/2)(6 \cdot a) = 3a[/tex]

We know this area is < 18

So 3a < 18

Dividing both sides by 3 gives us
3a/3 < 18/3

a < 6

So height a must be less than 6 inches.
Height cannot be 0 so the lower bound on height is

a > 0

Putting these together we get the rang of a as
0 < a < 6

In Interval notation this is written as (0, 6)

Answer:

To find 47% of 900, you can multiply 900 by 0.47, which represents 47% as a decimal:

47% = 47/100 = 0.47

So, 47% of 900 is:

0.47 x 900 = 423

Therefore, 47% of 900 is 423.

Convert 47% to a decimal

= 47% = 47/100 = 0.47

47%= 0.47 × 900

=423

Using the Pythagorean theorem, if AL is perpendicular to BD and CM is perpendicular to BD, then quadrilateral ABCD is a parallelogram.

In a parallelogram, the opposite sides are equal in length, i.e. AL = CD and BM = AD.

By the Pythagorean theorem, we know that the length of the diagonal BD can be found as the square root of the sum of the squares of AL and CM:

BD = √(AL^2 + CM^2)

Since AL = CD, the area of quadrilateral ABCD can be found as:

ar (quad.ABCD) = AL × BD

Substituting BD = √(AL^2 + CM^2) and combining the two equal length sides, we get:

ar (quad.ABCD) = (AL + CM) × √(AL^2 + CM^2) / 2

Finally, dividing both sides by √(AL^2 + CM^2) and using the fact that BD = √(AL^2 + CM^2), we get:

ar (quad.ABCD) = 1/2 × BD × (AL + CM)

Thus, we have proved that the area of quadrilateral ABCD is equal to 1/2 × BD × (AL + CM).

Answer:

y = -x +8

Step-by-step explanation:

The line crosses the x axis at 8. So we know when y = 0 then x = 8

The line cross the y axis at 8. so we know when x = 0 then y = 8

the equation of a line we know to take the form y = mx + c

When x = 0 and y = 8, and y = mx+ c then then c =8

when y = 0 x = 8. y = mx + c, 0 = m(8) +8. for this to be true m must be equal to -1

so the equation of the line, the inequality is y = -x +8

Between the time interval 0 to 1 hour, the greatest average rate of change is 700. Therefore, the option (1) is the correct answer.

The slope or rate of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y₂-y₁)/(x₂-x₁).

Here,

1) 0 to 1 hour

Consider the coordinate points (0, 0) and (1, 700)

Now, rate = (700-0)/(1-0)

= 700

2) 1 hour to 1.5 hours

Consider the coordinate points (1, 700) and (1.5, 900)

Now, rate = (900-700)/(1.5-1)

= 200/0.5

= 400

3) 2.5 hours to 5 hours

Consider the coordinate points (2.5, 1000) and (5, 1640)

Now, rate = (1640-1000)/(5-2.5)

= 640/2.5

= 256

4) 5 hours to 8 hours

Consider the coordinate points (5, 1640) and (8, 1800)

Now, rate = (1800-1640)/(8-5)

= 160/3

= 53.33

Using equations, we know that the age of Geraldine and Steven is t - 4 and 2t - 8 respectively.

It basically consists of a variable, perhaps with an additional numerical constant.

To easily understand this concept, consider the example below. 3x – 4 = 5. It is a straightforward class 7 equation.

The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions.

So, we have the following algebraic expression after converting the word problem:

To Geraldine:

g = t - 4

To Steven:
s = 2g

Inputting Tom's age into equation 1 results in:

g = t - 4

Step-by-step explanation:

The sum of interior angles of an n-sided polygon = [tex](n- 2 )[/tex] x [tex]180^{o}[/tex]

where n = number of sides

For all the four figures in this exercise, n = 4

Therefore, Sum of interior angles = [tex](4 - 2)[/tex] x [tex]180^{o}[/tex]

                                                          = 2 x [tex]180^{o}[/tex]

For Exercise 11:

[tex]x^{o} + 100^{o} + 130^{o} + 66^{o} = 360^{o}[/tex]

Answer: Let's call the measure of the angle x.

The complement of the angle is (90 - x) degrees, and the supplement is (180 - x) degrees.

So, using the information given in the problem, we can set up an equation:

5 * (90 - x) = 2 * (180 - x) - 24

Expanding both sides and simplifying, we get:

450 - 5x = 360 - 2x - 24

Solving for x, we get:

6x = 294

x = 49

Therefore, the measure of the angle is 49 degrees.

The inequality used to determine v, the minimum number of visits Taylor needs to earn her first free movie ticket is 75 + 6.5v ≥ 100.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Given,

Points for signing up = 75 points

Points for each visit to the movie theater = 6.5 points

Let v be the minimum number of visits Taylor needs to earn her first free movie ticket.

Points earned for v visits = 6.5v

She needs at least 100 points for a free movie ticket.

75 + 6.5v will be the points she earn for a free movie ticket.

This expression must be greater than 100, which is the required points for a free movie.

In the case presented, the range is the difference between the maximum value and the minimum value of the data. The range describes the breadth of the data and how much they vary from the minimum value to the maximum value. Therefore, the range indicates the dispersion of the data.

The statement indicates that the range is 5, which means that the most flights made by students is 5. Since the data has a narrow dispersion, we can conclude that most students have taken a similar number of flights, implying that most students have flown an amount close to the maximum number observed.

Therefore, the option that best describes the dispersion of the data is: "The data has a range of 5, which is a narrow dispersion. This means that most students have taken a similar number of flights."
