ANSWER

[tex]f(x) = x - 12[/tex]

EXPLANATION

The first x-value is 32.

When we subtract 12 from 32, we get:

[tex]32 - 12 =2 0[/tex]

The next y-value is 14.

When we subtract 12 from 14, we get:

[tex]14 - 12 = 2[/tex]

Also when we subtract 12 from -2, we get,

[tex] - 2 - 12 = - 14[/tex]

Let m be the missing x-value,then

[tex]m - 12 = - 6[/tex]

This implies that,

[tex]m = - 6 + 12[/tex]

[tex]m = 6[/tex]

Let n be the missing y-value, then

[tex] - 10 - 12 = n[/tex]

[tex]n = - 22[/tex]

Therefore we can generalize and write the function rule,

[tex]f(x) = x - 12[/tex]

Step-by-step explanation:

It is solved above

no of children and adult are let as x and y respectively

Galen sold 195 adult tickets and 645 children's tickets at the church carnival.

Let's assume that the number of adult tickets sold is x.

The number of children's tickets sold is 30 more than 3 times the number of adult tickets sold. So, the number of children's tickets sold would be 3x + 30.

The total amount earned from selling adult tickets would be 5x, and the total amount earned from selling children's tickets would be 3(3x + 30) = 9x + 90.

Since the total amount earned from selling all the tickets is $2820, we can set up the equation:

5x + 9x + 90 = 2820

Simplifying the equation,

14x + 90 = 2820

Subtracting 90 from both sides,

14x = 2730

Dividing both sides by 14,

x = 195

Therefore, Galen sold 195 adult tickets. And the number of children's tickets sold would be 3(195) + 30 = 615 + 30 = 645.

If we assume that she was walking in a straight line then turned 90 degrees, we would say that it was a right angle of a 90 degree angle.

Hope this helps:)

Madeline made a right angle by turning 90° to the left, which exactly measures 90 degrees and is one of the fundamental angle types in geometry.

Madeline made a 90° turn to the left, which is described as a right angle. A right angle is an angle that measures exactly 90 degrees. This is a common type of angle found in many different contexts, such as the corner of a square or rectangle. In geometry, right angles are significant because they have unique properties that distinguish them from other types of angles, such as acute angles (less than 90°), obtuse angles (more than 90° and less than 180°), and straight angles (180°).

The answer is:

The answer is the fourth option,

[tex]f(-3)=-\frac{1}{3}[/tex]

Piecewise functions are functions that are composed by two or more expressions, the expression to use will depend of the domain or input that we need to evaluate.

We are given the piecewise function:

[tex]\left \{ {{\frac{1}{x}, if x<-2} \atop{x^{2}, ifx\geq 2}} \right.[/tex]

There, we know that:

We should use the first expression if the value to evaluate is less than -2.

So, for this case, the function will be:

[tex]f(x)=\frac{1}{x}[/tex]

We should use the second expression if the value to evaluate is greater or equal than 2.

So, for this case, the function will be:

[tex]f(x)=x^{2}[/tex]

Now, since we are given that the value to evaluate is -3, and its less than -2, we need to use the first expression, and evaluate it.

[tex]-3<-2[/tex]

So, evaluating the function we have:

[tex]f(x)=\frac{1}{x}[/tex]

[tex]f(-3)=\frac{1}{-3}[/tex]

[tex]f(-3)=-\frac{1}{3}[/tex]

Hence, we have that the answer is the fourth option,

[tex]f(-3)=-\frac{1}{3}[/tex]

The portion of the trip through the mountains was 112.5 miles.

To find this, first, let's denote the time spent in the plains as [tex]\( t_1 \)[/tex] and the time spent in the mountains as [tex]\( t_2 \)[/tex]. Since the total trip took 3 hours and 48 minutes (which is[tex]\( \frac{3}{4} \) hours[/tex]), we have:

[tex]\[ t_1 + t_2 = 3.75 \][/tex]

The distance traveled in the plains is [tex]\( d_1 = 90t_1 \)[/tex] and in the mountains is[tex]\( d_2 = 37.5t_2 \)[/tex]. The total distance traveled is 300 miles, so:

[tex]\[ d_1 + d_2 = 300 \][/tex]

Substituting the expressions for [tex]\( d_1 \)[/tex] and [tex]\( d_2 \):[/tex]

[tex]\[ 90t_1 + 37.5t_2 = 300 \][/tex]

We can rearrange the first equation to express [tex]\( t_1 \)[/tex] in terms of [tex]\( t_2 \)[/tex]:

[tex]\[ t_1 = 3.75 - t_2 \][/tex]

Substituting this into the second equation:

[tex]\[ 90(3.75 - t_2) + 37.5t_2 = 300 \][/tex]

[tex]\[ 337.5 - 90t_2 + 37.5t_2 = 300 \][/tex]

[tex]\[ 337.5 - 52.5t_2 = 300 \][/tex]

[tex]\[ 52.5t_2 = 37.5 \][/tex]

[tex]\[ t_2 = \frac{37.5}{52.5} \][/tex]

[tex]\[ t_2 = \frac{5}{7} \] hours[/tex]

Now, to find the distance traveled in the mountains:

[tex]\[ d_2 = 37.5 \times \frac{5}{7} \][/tex]

[tex]\[ d_2 = 112.5 \] miles[/tex]

So, the portion of the trip through the mountains was 112.5 miles.

Answer:

B

Step-by-step explanation:

The volume of a rectangular prism is the length times width times height.

V = LWH

V = (4√3)(3√6)W

V = 12√18 W

V = 36√2 W

If the volume is irrational, then W cannot have a radical that is half of a perfect square, because when multiplied by √2, that would yield a rational volume.  For example, √18 × √2 = √36 = 6.

Therefore, the answer must be B, because 12 is not half of a perfect square.

V = 36√2 (4√12)

V = 144√24

Answer:

x = 6

Step-by-step explanation:

Equation: x² - 12x + 36 = 0

Quadratic formula: ax² + bx + c = 0 --> x = (-b ± √(b² - 4ac))/2a

Substitute: x = (12 ± √(12² - 4 * 36))/2

Multiply: x = (12 ± √(144 - 144))/2

Subtract: x = (12 ± 0)/2

Solve: x = 6

Answer:

The value of x = 6

Step-by-step explanation:

Points to remember

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

x = [-b ± √(b² - 4ac)]/2a

It is given that,

x² -12x + 36 = 0

To find the solution of given equation

Here a = 1, b = -12 and c = 36

x = [-b ± √(b² - 4ac)]/2a

 =  [--12 ± √((-12)² - 4*1*36)]/2*1

 = [12 ± √(144 - 144)]/2

 = 12/2 = 6

The value of x = 6

After shifting [tex]8[/tex] units towards the right, it will become [tex](8,0)[/tex].

Therefore, the equation of the new parabola will be [tex]y=(x-8)^{2}[/tex].

Hence, the answer is [tex]y=(x-8)^{2}[/tex].

The equation to the new parabola is [tex]y=(x-8)^{2}[/tex].

What is the equation of a parabola?

The general equation of a parabola is: y = a(x-h)2 + k or x = a(y-k)2 +h, where (h,k) denotes the vertex. The standard equation of a regular parabola is y2 = 4ax.

A parabola is nothing but a U-shaped plane curve. Any point on the parabola is equidistant from a fixed point called the focus and a fixed straight line known as the directrix. Terms related to Parabola.

The way that you would be able to show -63 is 126/-2

The decimal 2.63 is not recurring. However, 2.63 can be expressed as the fraction 263/100 but it cannot be simplified further.

To express the repeating decimal number 2.63 as a quotient of two integers, we can use a straightforward method. First, let's identify the repeating part, which is the "63" after the decimal point. This part repeats infinitely. To convert this into a fraction, we need to set up an equation where x is the repeating decimal:

x = 2.63

Now, we'll subtract the non-repeating part to isolate the repeating part:

100x = 263 (multiplied both sides by 100 to eliminate the decimal)

Now, we'll subtract x from 100x:

100x - x = 263 - 2.63

99x = 260.37

To isolate x, we divide both sides by 99:

x = 260.37 / 99

Now, we can simplify the fraction:

x = 26037 / 9900

To express 2.63 as a quotient of two integers, it is equal to 26037/9900. This fraction can be simplified further if needed, but it is already in the form of two integers.

n = ?

Formula

Sum = (  (2*a1) + (n - 1)*d) * n / 2   Substitute the knows.

Solution

Sum = ( 2 * 5 + (n - 1)*5 ) * n/2      Combine on the right

275 = (10 + (n - 1)5 ) n/2                Multiply by 2 and remove the brackets.

550 = (10 + 5n - 5) * n                  Combine

550 = (5 + 5n ) * n                        Remove the brackets

550 = 5n + 5n^2                          Subtract 550 from both sides.

5n^2 + 5n - 550 = 0                     Divide by 5 (all terms are divisible by 5)

n^2 + n - 110 = 0                           Factor

Step-by-step explanation:

Points to remember

Volume of cone = (πr²h)/3

Where r - Radius of cone and

h - Height of cone

To find the volume of given cone

From the figure we can see,

Radius r = 8 m and Height h = 21 m

Volume = (πr²h)/3

 = (π * 8² * 21)/3

 = π * 64 * 7 = 448π

Therefore volume of cone = 448π m³

Step-by-step explanation:

Final answer:

The correct answer is D. 0, since the question involves a positive elevation (3 feet above the painting) and does not appropriately call for the use of negative numbers to describe the position of the ceiling relative to the painting.

Explanation:

The question asks about the location of the ceiling in the room relative to the top of the painting, given that the ceiling is 3 feet above the top of the painting and the wall height is 10 feet. To determine this, we can use the information provided without needing to consider mathematical concepts such as negative numbers in a non-standard context.

Since the ceiling is 3 feet above the top of the painting, and this measurement is given in a direct, positive manner, the idea of using negative numbers to describe this position is not applicable. Choices A (-10), B (-7), and C (-3) suggest a misunderstanding of the question's context. The correct answer is D. 0, as it is the only option that does not assign a negative value to describe a position that is above the painting, thereby avoiding the inappropriate assignment of negative numbers to a scenario where they are not contextually relevant.

Thus, the number 3 describes the location of the ceiling in the room relative to the top of the painting as a positive elevation, not as a negative value or a ill-suited attempt to describe spatial positions in a non-intuitive manner.
