The correct options are:

C. It is a hyperbola.

D. It is in quadrants I and II.

The reciprocal parent function is given by:

f(x) = 1/x

The graph of this function is a hyperbola, which opens up and down, and has vertical asymptotes at x = 0 (the y-axis).

The graph is in quadrants I and II, since x > 0 for positive values of y, and x < 0 for negative values of y.

The graph does not go through the origin (0,0), since f(0) is undefined. It is not a parabola, since a parabola is a U-shaped curve, which is not the shape of the reciprocal parent function.

The image of point C(-3,0) after a 180° counterclockwise rotation around the origin is the point (3,0).

To graph the image of point C(-3,0) after a 180° counterclockwise rotation around the origin, we can use the following formula:

(x', y') = (-x, -y)

where (x, y) are the coordinates of the original point, and (x', y') are the coordinates of its image after rotation.

Using this formula, we get:

(x', y') = (-(-3), -(0)) = (3, 0)

So, the image of point C(-3,0) after a 180° counterclockwise rotation around the origin is the point (3,0).

It would take Rafael approximately 9.05 hours to run a 50-mile marathon in Washington D.C. at the same pace he ran the Boston Marathon.

What is distance?

Distance is the measure of how far apart two objects or locations are from each other. It is usually measured in units such as meters, kilometers, miles, or feet.

To solve this problem, we can use the concept of the average speed or pace, which is given by the formula:

pace = time / distance

where pace is the time it takes to cover one unit of distance (e.g., one mile), time is the time taken to cover the distance, and distance is the distance covered.

We can rearrange this formula to find the time it would take to cover a given distance at a given pace:

time = pace * distance

Using this formula, we can find the pace at which Rafael ran the Boston Marathon:

pace = time / distance

pace = 4.75 hours / 26.2 miles

pace = 0.181 hours/mile

Now we can use this pace to find the time it would take Rafael to run a 50-mile marathon:

time = pace * distance

time = 0.181 hours/mile * 50 miles

time = 9.05 hours

Therefore, it would take Rafael approximately 9.05 hours to run a 50-mile marathon in Washington D.C. at the same pace he ran the Boston Marathon.

The measure of a central angle of a regular polygon with 24 sides is 15 degrees.

A polygon is a two-dimensional geometric shape that is defined by a closed chain of line segments, also known as sides. These line segments must be joined end to end to form a closed shape, with no curves or self-intersections. The word "polygon" comes from the Greek words "poly" meaning "many" and "gon" meaning "angle".

To find the measure of a central angle of a regular polygon with 24 sides, we can use the formula:

central angle = 360 degrees / number of sides

Substituting the given value, we get:

To find the proportion of observations on the Standard Normal Curve between z = -1.8 and z = 0.67, we need to find the area under the curve between these two values.

Using the Standard Normal Table, we can find the area to the left of z = -1.8 and z = 0.67, and then subtract the former from the latter to get the area between them.

The area to the left of z = -1.8 is 0.0359, and the area to the left of z = 0.67 is 0.7486.

Therefore, the area between z = -1.8 and z = 0.67 is:

0.7486 - 0.0359 = 0.7127

So the proportion of observations on the Standard Normal Curve between z = -1.8 and z = 0.67 is approximately 0.7127, or 71.27%.

The simplified form of the expression (8h + 7) - (7h + 6) is h + 1. We subtract this by using the distributive law.

An expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, division, exponentiation, etc.) that represents a mathematical quantity or value. Expressions can be simple, consisting of just a single number or variable, or they can be complex, involving multiple numbers, variables, and operations.

The distributive law, also known as the distributive property or distributive property of multiplication over addition, is a fundamental property of arithmetic and algebra that allows the distribution of a multiplication operation over an addition or subtraction operation.

The distributive law states that for any three numbers a, b, and c:

a × (b + c) = (a × b) + (a × c)

According to the given information:

To subtract (8h + 7) - (7h + 6), we can use the distributive property of multiplication over addition to simplify the expression.

(8h + 7) - (7h + 6)

= 8h + 7 - 7h - 6 (Applying the distributive property)

Now, we can combine like terms by adding or subtracting coefficients of the same variable:

= (8h - 7h) + (7 - 6) (Grouping-like terms)

= h + 1 (Simplifying)

So, the simplified form of the expression (8h + 7) - (7h + 6) is h + 1.

If PQRS are points on a circle with the centre O, PS is a diameter of the circle Angle PQR=136, the measure of angle RPS is 88 degrees.

Since QR is parallel to PS, we can use alternate interior angles to determine that angle QPS is equal to angle PQR. This means that angle QPS is also 136 degrees.

Angle PQR and angle QPS both subtend the same arc, which is the arc between points P and R on the circle. Therefore, the two angles are equal.

We can use this fact to find the measure of angle RPS. First, we know that the sum of angles in a quadrilateral is 360 degrees. Therefore, we can find the measure of angle PSR as follows:

Angle PSR = 360 degrees - Angle PQR - Angle QPS

Angle PSR = 360 degrees - 136 degrees - 136 degrees

Angle PSR = 88 degrees

Next, we use the fact that angles at the circumference of a circle subtended by the same arc are equal. Angle PSR and angle RPS both subtend the same arc, which is the arc between points P and R on the circle. Therefore, the two angles are equal.

AC is congruent to DF by the definition of congruency. Applying SSS Congruency, Triangle ABC is congruent to DEF, and since Triangle DEF is a right angled triangle, Triangle ABC is also a right angled triangle with angle B as 90 degrees.

AB is congruent to DB because segment DE was constructed so that DE = AB, BC is congruent to EF, because segment EF was constructed so that EF = BC, and since Triangle DEF is a right angled triangle, we have:

DE² + EF² = DF² (Pythagoras Theorem)

We are also given that:

AB² + BC² = AC²

Since DE = AB and EF = BC, we can substitute these values in the above equation to get:

DE² + EF² = AC²

Thus, we can substitute the above value of AC² in the equation DE² + EF² = DF² to get:

DE² + EF² = DF² = AB² + BC²

Taking the square root on both sides, we get:

DF = √(AB² + BC²)

Since AC² = AB² + BC², we can write:

DF = √AC²

Therefore, AC is congruent to DF by the definition of congruency. Applying SSS Congruency, Triangle ABC is congruent to DEF, and since Triangle DEF is a right angled triangle, Triangle ABC is also a right angled triangle with angle B as 90 degrees.

Let's call the length of the rectangle "l" and the width "w". We know that the diagonal of the rectangle is 60 inches, and that it creates angles of 30 degrees and 60 degrees in the corners of the rectangle.

Using trigonometry, we can relate the sides of the rectangle to its diagonal and the angles formed by the diagonal. Specifically, we can use the sine and cosine functions to relate the sides to the angles:

sin(30) = w/60 and cos(30) = l/60

sin(60) = l/60 and cos(60) = w/60

Simplifying each equation, we get:

w = 30√3 and l = 30

Therefore, the area of the rectangle is:

Area = l x w = (30)(30√3) = 900√3 square inches.

Hence, the area of the rectangle in simplified radical form is 900√3 square inches.

The biggest effect of electing so many public officials is that it can be difficult for voters to make informed decisions.

With so many candidates to choose from, voters may not have the time or resources to thoroughly research each candidate and their qualifications. This can lead to uninformed voting, where voters may simply choose a candidate based on their name recognition, party affiliation, or other superficial factors.

Additionally, contested elections can also lead to an increase in negative campaigning and attack ads, which can further cloud voters' perceptions of the candidates and the issues at stake. Ultimately, electing a large number of public officials can make it harder for voters to feel confident in their choices and can undermine the democratic process.

We are given that V1 = 2.2 liters, T1 = 18°C, and T2 = 38°C. We need to find V2.
