The reflection that occurred is over the x-axis.

Based on the given coordinates, it can be observed that each point of the pre-image was reflected over the x-axis, resulting in a new image. Therefore, the type of reflection that occurred is a reflection over the x-axis.

To explain this with equations, we can use the transformation formula for a reflection over the x-axis:

(x, y) → (x, -y)

Using this formula, we can find the image coordinates of the pre-image points:

A' = (-1, -8)

B' = (5, 3)

C' = (-5, 1)

As we can see, the y-coordinates of each point have been negated, indicating a reflection over the x-axis. Therefore, the type of reflection that occurred is a reflection over the x-axis.

A = 46.74 mi²

Step-by-step explanation:

the area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{h}[/tex] (b₁ + b₂ )

where h is the perpendicular height between the bases b₁ and b₂

here h = 8.2 , b₁ = 9 , b₂ = 2.4

then

A = [tex]\frac{1}{2}[/tex] × 8.2 × (9 + 2.4) = 4.1 × 11.4 = 46.74 mi²

Sure, I'll be happy to help you with your question. In order to find the measure of the missing angle and arc, we first need to know what type of angle and arc we are dealing with. If it is a central angle and arc, then the measure of the angle is equal to the measure of the arc. However, if it is an inscribed angle and arc, then the measure of the angle is half the measure of the arc.

Once we have determined the type of angle and arc, we can use the given information to solve for the missing measure. For example, if we are given the measure of the angle and the measure of the arc, we can use the formula for the measure of a central angle or inscribed angle to solve for the missing measure.

Alternatively, we can also use the properties of circles, such as the fact that the sum of the angles in a triangle is 180 degrees and the fact that the angle at the center of a circle is twice the angle at the circumference, to solve for the missing measure.

In any case, . With enough practice and familiarity with these concepts, you can become proficient at solving problems involving missing angles and arcs.

Standard form for the equation of a circle is:

Convert the given equation into standard form:

Its center is ( 1, 0) and radius is r = 3.

Let's verify the statements:

Answer:

See below

Step-by-step explanation:

To find:-

Answer:-

The given equation of the circle is ,

[tex]\longrightarrow x^2+y^2-2x-8 = 0 \\[/tex]

For finding the correct statements , we need to convert this equation into standard form for a circle.

The standard equation of circle is given by,

[tex]\boxed{\begin{tabular}{c}\textbf{\underline{ \red{Standard\ equation\ of \ circle }}} \\ \\ \text{ The standard equation of a circle is given by:-} \\\\ \longrightarrow \underline{\underline{ (x-h)^2+(y-k)^2 = r {}^{2}}} \\\\ \text{where} , \\\\ \bullet\text{ (h,k) is the centre of the circle.}\\\\\bullet\text{ "r" is the radius of the circle. }\\\end{tabular}}[/tex]

Now for that we need to complete the square for "x" . This can be done by ,

Rearrange the terms,

[tex]\longrightarrow x^2-2x + y^2-8 = 0 \\[/tex]

Add and subtract 1² .

[tex]\longrightarrow ( x^2 -2x +1^2 ) - 1^2 + y^2-8=0 \\[/tex]

Simplify,

[tex]\longrightarrow (x^2-2(1)x+1^2) - 1-8 + y^2=0 \\[/tex]

Notice that the terms inside the small brackets are in the form of a² - 2ab + b² , which is the whole square of (a-b) . So we can write it as,

[tex]\longrightarrow (x-1)^2 +y^2 - 9 = 0 \\[/tex]

Add 9 on both the sides ,

[tex]\longrightarrow (x-1)^2 + y^2 = 9\\[/tex]

This can be written as,

[tex]\longrightarrow \underline{\underline{ \boldsymbol{(x-1)^2+(y-0)^2 = 3^2}}} \\[/tex]

On comparing it to the standard form, we have;

[tex]\longrightarrow\boxed{ \text{Center = (1,0) }} \\[/tex]

[tex]\longrightarrow\boxed{ \text{ Radius = 3 \ units}} \\[/tex]

Let's check the given statements ,

Statement 1: The radius of the circle is 3 units.

Statement 2: The centre of the circle lies on the x-axis.

Statement 3: The statement of the circle lies on the y-axis.

Statement 4: The standard equation of the circle is (x-1)²+y² = 3

Statement 5: The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

To find the total percentage decrease, we first need to find the new values of the stocks in Company A and Company B after the decrease.

The new value of the stock in Company A is: $5800 - (1% \times $5800) = $5742

The new value of the stock in Company B is: $7470 - (20% \times $7470) = $5976

To find the total value after the decrease, we add these two values: $5742 + $5976 = $11718

To find the percentage decrease from the original total value ($5800 + $7470 = $13270) to the new total value ($11718), we use the formula:

percentage decrease = [(original value - new value) / original value] x 100%

percentage decrease = [($13270 - $11718) / $13270] x 100%

percentage decrease = 11.7%

Therefore, the total percentage decrease in the investor's stock account is 11.7%.

If ∠1 and ∠2 are vertical angles and m∠22 = 180°, then m∠1 = 90°

Vertical angles are pairs of angles that are opposite to each other when two lines intersect. Vertical angles are always equal in measure. Therefore, if ∠1 and ∠2 are vertical angles, then:

∠1 = ∠2

We are also given that m∠22 has a measure of 180°. Since ∠1 and ∠2 are vertical angles, they form a straight line, and their measures add up to 180°. Therefore:

∠1 + ∠2 = 180°

Since ∠1  = ∠2, we can substitute ∠1 for ∠2 in the above equation:

∠1 + ∠1 = 180°

Simplifying the equation, we get:

2∠1 = 180°

Dividing both sides by 2, we get:

∠1 = 90°

Therefore, ∠1 has a measure of 90°.

the particular solution to the differential equation. we use the positive sign: [tex]y = -1 + e^(1/2 x^2 + x - 5.605)[/tex]

To find the particular solution to the differential equation {dy}/{dx} = (x+1) (y+1) with the initial condition y(4) = 3, we can use separation of variables and integration.

First, we can rewrite the equation as:

[tex]{1}/{(y+1)} dy = (x+1) dx[/tex]

Next, we can integrate both sides:

[tex]∫ {1}/{(y+1)} dy = ∫ (x+1) dx[/tex]

[tex]ln|y+1| = 1/2 x^2 + x + C[/tex]

where C is the constant of integration.

To determine the value of C, we can use the initial condition y(4) = 3:

[tex]ln|3+1| = 1/2 (4)^2 + 4 + C[/tex]

[tex]ln|4| = 10 + C[/tex]

[tex]C = ln|4| - 10 = -5.605[/tex]

Therefore, the particular solution to the differential equation with the initial condition y(4) = 3 is:

[tex]ln|y+1| = 1/2 x^2 + x - 5.605[/tex]

Solving for y:

[tex]|y+1| = e^(1/2 x^2 + x - 5.605)[/tex]

[tex]y+1 = \pm e^(1/2 x^2 + x - 5.605)[/tex]

[tex]y = -1 \pm e^(1/2 x^2 + x - 5.605)[/tex]

Hence, the value of y is 23 when x = 7.

Describe equation?

A mathematical equation is a formula that uses the equals symbol (=) to denote the equality of two expressions.

A formula would be 3x - 5 = 16,

for instance. We may determine the value of the variable x by solving this equation: x = 73.

The slope-intercept representation of the equation can be used to determine the equation of a line running through the points (x1, y1) and (x2, y2):

y - y1 = m(x - x1) (x - x1)

where m is the line's slope. The following formula can be used to determine the line's slope:

m = (y2 - y1) / (x2 - x1) (x2 - x1)

Now put the x and y value in this:

slope of the line using the points (1, 5) and (3, 11):

m = (11 - 5) / (3 - 1) = 6 / 2 = 3

We can use the slope of the line to determine the equation of the line now that we know it:

y - y1 = m(x - x1) (x - x1)

y - 5 = 3(x - 1) (x - 1)

y - 5 = 3x - 3 = 3x + 2

In light of this, the equation for the line connecting points (1, 5) and (3, 11) is y=3x+2

To determine the value of y for x = 7, we can utilize the equation of the line we discovered earlier:

In Option A it is given that patriot is more popular in students while viking is more popular in teachers which is not correct.

In option C patriot is equally popular in students and teachers, which is also not correct. because patriot is popular in 20% of students but 80% in teachers, which is not correct.

In option B there is no difference between students and teachers, this statement is also not correct because there is lots of differences in their choices.

In Option D it is said that viking is more popular in students but patriot is more popular in teachers. this is correct.

Answer:

13 meters.

Step-by-step explanation:

We can use the formula for the volume of a rectangular prism, which is:

Volume = length x width x height

We are given that the base area (length x width) of the prism is 54 m², so we can write:

length x width = 54 m²

We are also given that the volume of the prism is 702 m³, so we can write:

Volume = length x width x height = 702 m³

We want to find the height of the prism, so we can rearrange the formula for the volume to solve for height:

height = Volume / (length x width)

Substituting the given values, we get:

height = 702 m³ / 54 m²

Simplifying this expression, we can divide both the numerator and the denominator by the greatest common factor of 54 and 702, which is 18:

height = (702/18) m / (54/18) m = 39 m / 3 m

height = 13 meters

Therefore, the height of the rectangular prism is 13 meters.

Option D is the correct option i.e., 2.5 hours. Timing is everything when it comes to dining before a fight. Athletes must ingest enough calories to power their efforts without developing gastrointestinal pain or bloating while competing. Typically, a substantial dinner should be eaten two to three hours prior to the game. 

The body needs time to process and assimilate nutrients, which is the cause of this. A big dinner requires the body to divert a lot of blood flow to the digestive system, which can have an impact on an athlete's performance. Athletes' performance can be hampered by sluggishness, gastrointestinal pain, or even vomiting brought on by eating too close to a competition.

In general, it is recommended that athletes experiment with different meal timings and types of food during their training to determine what works best for their individual needs.

They should also consider the length of the event and the intensity of their activity to determine the amount and timing of their meals. A registered dietitian or sports nutritionist can help athletes create a personalized nutrition plan to optimize their performance.
