We know that the temperature was 56°F at midnight, so we can plot the point (24, 56)

What is graph ?

Graph can be defined as visual representation of given data using the ordered pairs.

To graph Elroy's data, we can use the x-axis to represent the time of day in hours and the y-axis to represent the temperature in degrees Fahrenheit.

First, we can plot the point (6, 50) to represent the temperature at 6am.

Next, we can use the information that the temperature rose 3° per hour for the next 4 hours. This means that at 10am, the temperature would be 50 + 3(4) = 62°F. We can plot this point at (10, 62). Similarly, we can find the temperature at 7am, 8am, and 9am using the same formula and plot those points as well.

Then, we can use the information that the temperature rose 2° per hour for the next 6 hours. This means that at 4pm, the temperature would be 62 + 2(6) = 74°F. We can plot this point at (16, 74). Similarly, we can find the temperature at 11am, 12pm, 1pm, 2pm, and 3pm using the same formula and plot those points as well.

The temperature then stayed steady until 6pm, so we can draw a horizontal line at y = 74 from 4pm to 6pm.

For the next 2 hours, the temperature dropped 1° per hour. This means that at 8pm, the temperature would be 74 - 2 = 72°F. We can plot this point at (20, 72). Similarly, we can find the temperature at 7pm using the same formula and plot that point as well.

Therefore,  we know that the temperature was 56°F at midnight, so we can plot the point (24, 56).

There are 100,000 possible five-digit student ID numbers that can be created if repeat digits are allowed (10^5).

However, if repeats are not allowed, there are only 9 x 9 x 9 x 9 x 9 = 590,490 possible student ID numbers that can be created (9^5).

The reason for the difference is that when repeats are allowed, you can use the same digit multiple times, for example "11111".

When repeats are not allowed, you can only use each digit once, for example "12345". The possible permutations of the digits 0-9 increase as more digits are added to the ID number, meaning that the more digits there are, the more possible combinations there are.

Therefore, when repeats are not allowed, the number of possible combinations is reduced significantly. In the case of five-digit student ID numbers, the difference is almost twofold.

A sample size of 1068 is needed with a 95% confidence level and a 3% margin of error to estimate the proportion of people who support a political candidate.

To determine the sample size needed to estimate the percentage of people who support the political candidate with a 3% margin of error at a 95% confidence level, we can use the formula:

n = (z^2 * p * (1 - p)) / (E^2)

where n is the sample size, z is the z-value corresponding to the desired confidence level (95% confidence level corresponds to z = 1.96), p is the estimated proportion of the population that supports the candidate (we can use 0.5 as a conservative estimate), E is the desired margin of error (3% or 0.03)

Substituting the values into the formula, we get:

n = (1.96^2 * 0.5 * (1 - 0.5)) / (0.03^2) = 1067.11

Rounding up to the nearest integer, we need a sample size of 1068 to estimate the percentage of people who support the political candidate with a 3% margin of error at a 95% confidence level.

The formula to calculate interest charge when the musician does not make any payments for one month is Interest = Principal * Rate * Time. Using the given values, the interest charge for the first month is $97.15, making the total owed amount at the end of the first month $2,997.15.

If the musician does not make any payments for one month, the amount owed will accumulate interest. To calculate the interest charge, we can use the following formula:

Interest = Principal * Rate * Time

where the principal is the initial amount owed, the rate is the monthly interest rate as a decimal, and the time is the time period in months.

In this case, the principal is $2,900, the monthly interest rate is 3.35% expressed as a decimal (0.0335), and the time is one month.

So, the interest charge for the first month will be:

Interest = $2,900 * 0.0335 * 1

Interest = $97.15

Therefore, at the end of the first month, the musician will owe the initial balance of $2,900 plus the interest charge of $97.15, for a total of $2,997.15.

The distance from the bottom of the building to the point where the ladder is touching the building for Triangle 2 is 14 feet.

What is triangle?

A triangle is a polygon with three sides and three angles. It is one of the most basic geometric shapes and is often used in geometry, trigonometry, and other branches of mathematics.

Since Triangle 1 and Triangle 2 are similar right triangles formed from the same ladder leaning against the same building, their corresponding sides are proportional to each other.

Let's use the concept of similarity and proportions to solve for the unknown distance in Triangle 2. We can set up the following proportion based on the corresponding sides of the two triangles:

(vertical leg of Triangle 1) : (horizontal leg of Triangle 1) = (vertical leg of Triangle 2) : (horizontal leg of Triangle 2)

We know that in Triangle 1:

the length of the hypotenuse (the ladder) is 16 feet

the length of the horizontal leg (the distance along the ground) is 8 feet

the length of the vertical leg (the distance from the bottom of the building to the point where the ladder is touching the building) is 16 feet

Using the Pythagorean Theorem, we can solve for the length of the vertical leg of Triangle 2:

(vertical leg of Triangle 1) : (horizontal leg of Triangle 1) = (vertical leg of Triangle 2) : (horizontal leg of Triangle 2)

16 : 8 = (vertical leg of Triangle 2) : 7

Simplifying the proportion, we get:

2 : 1 = (vertical leg of Triangle 2) : 7

To solve for the vertical leg of Triangle 2, we can multiply both sides of the proportion by 7:

2 * 7 : 1 * 7 = (vertical leg of Triangle 2)

14 : 1 = (vertical leg of Triangle 2)

Therefore, the distance from the bottom of the building to the point where the ladder is touching the building for Triangle 2 is 14 feet.

Benzoic acid is used to determine the heat capacity of bomb calorimeters because it can be obtained in pure form and its energy of combustion is known very accurately (-26.43 kJ/g).

The calorimeter constant is -2873.5.

Determine the calorimeter constant of the calorimeter that had a temperature increase of 9.199 degrees Celsius when 3.500 g of benzoic acid was used.To determine the calorimeter constant, follow these steps:

Explanation:

1. Calculate the energy released by the benzoic acid combustion: Multiply the mass of benzoic acid by its energy of combustion.
Energy released = mass × energy of combustion
Energy released = 3.500 g × -26.43 kJ/g = -92.505 kJ

2. Convert the temperature increase to a change in energy: Multiply the temperature increase by the mass of benzoic acid.
ΔEnergy = temperature increase × mass of benzoic acid
ΔEnergy = 9.199°C × 3.500 g = 32.1965 J

3. Determine the calorimeter constant: Divide the energy released by the change in energy.
Calorimeter constant = Energy released / ΔEnergy
Calorimeter constant = -92.505 kJ / 32.1965 J

Note: We need to convert the units to be consistent, either to J or kJ.
1 kJ = 1000 J, so -92.505 kJ = -92505 J.

Calorimeter constant = -92505 J / 32.1965 J = -2873.5

In geometry, a trapezoid is a four-sided polygon that has at least one pair of parallel sides. The parallel sides of a trapezoid are called bases, while the non-parallel sides are called legs.

The image below appears to be a trapezoid with vertices at A(2,2), B(4,5), C(6,5), and D(8,2). There are several ways to obtain this image, but here are two possible methods:

Method 1: Plotting the Points

One way to obtain the image is to plot the points A, B, C, and D on a coordinate plane, and then connect them in the correct order to form the trapezoid. Here are the steps:

Draw a coordinate plane with x and y axes.

Plot the point A at (2,2).

Plot the point B at (4,5).

Plot the point C at (6,5).

Plot the point D at (8,2).

Connect the points A, B, C, and D in the order ABDC to form the trapezoid.

Method 2: Transformations

Another way to obtain the image is to start with a reference trapezoid with known vertices, and then apply a sequence of transformations to obtain the desired trapezoid. Here are the steps:

Start with a reference trapezoid with vertices at (0,0), (2,3), (4,3), and (6,0). This trapezoid has the same shape as the desired trapezoid, but is located in a different position on the coordinate plane.

Translate the reference trapezoid 2 units to the right and 2 units up by adding (2,2) to each vertex. This results in a trapezoid with vertices at (2,2), (4,5), (6,5), and (8,2), which is the desired trapezoid.
