Answer:
B) 42 signifies the hourly rate, and 32 signifies the overhead charge
Step-by-step explanation:
The hourly rate is the amount of money given per hour worked. 42x basically means that for every hour, $42 are given.
As for 32, it is the overhead charge, which isn't paid every hour but rather only once. That is why it has no variable beside it.

5. The point of intersection is where two lines intersect.
Step-by-step explanation:
you have -x+2y=6. finding the slope is very easy, you just have to isolate y.
2y=6+x ---> y = 3+ x/2. The slope would be 1/2 for the first one. the y intercept would be 3.
To graph, there are different ways of doing it. You can do it by finding the y intercept and x intercept, by making a chart and finding plotting points, or you can do it graphing the y intercept and doing rise over run from there.

what is the distance between (-4,8) and (12,8) on a coordinate plane?
Answer:
16
Step-by-step explanation:
Final answer:
The distance between the points (-4,8) and (12,8) on a coordinate plane is 16 units, calculated by finding the difference between the x-coordinates since the y-coordinates are the same.
Explanation:
The question asks for the distance between the points (-4,8) and (12,8) on a coordinate plane. To find this distance, we can use the formula for the distance between two points in a plane:
d = √((x2 - x1)^2 + (y2 - y1)^2)
Since the y-coordinates are the same (8 and 8), the distance is simply the difference between the x-coordinates:
d = 12 - (-4) = 12 + 4 = 16
Therefore, the distance between the points (-4,8) and (12,8) is 16 units.

Which shows two triangles that are congruent by the SSS congruence theorem? Triangles A B C and D E C are connected at point C. Angles A B C and C E D are right angles. The lengths of sides A B and E D are congruent. Triangles A B C and D E C are connected at point C. The lengths of sides A B and D E are congruent. The lengths of sides B C and C D are congruent. Triangles A B C and D E C are connected at point C. The lengths of sides A C and C E are congruent. Angles B A C and C E D are congruent. Triangles A B C and A D C share common side A C. The lengths of A B and A D are congruent. The lengths of B C and D C are congruent.
Answer:
The last case shows that the two triangles are congruent by SSS congruency theorem
Step-by-step explanation:
Triangles A B C and A D C share common side A C. The lengths of A B and A D are congruent. The lengths of B C and D C are congruent.
With this case. You have sides AB = AD, BC = DC, and then can conclude that AC= AC by reflexive property because AC is the common side.
so triangle ABC = triangle ADC by SSS congruency
----------------------------
CASE 1.) Triangles A B C and D E C are connected at point C. Angles A B C and C E D are right angles. The lengths of sides A B and E D are congruent. ---- You would only know one pair of sides and one pair of angles that are congruent.
CASE 2.) Triangles A B C and D E C are connected at point C. The lengths of sides A B and D E are congruent. The lengths of sides B C and C D are congruent. ----- You would only know 2 pairs of congruent sides.
CASE 3.)Triangles A B C and D E C are connected at point C. The lengths of sides A C and C E are congruent. Angles B A C and C E D are congruent. ---- You would only know a pair of angles and a pair of sides. Not enough for congruency.
CASE 4.) Triangles A B C and A D C share common side A C. The lengths of A B and A D are congruent. The lengths of B C and D C are congruent.

The question concerns a college-level Physics model related to the Fokker-Planck equation and its application in classical and statistical mechanics, specifically in the context of explaining atomic stability, atomic size, and electron binding energy in atomic physics.
Explanation:
The equation and model described in the question appear to represent the principles of classical mechanics and statistical mechanics in Physics, especially when referencing the Fokker-Planck equation, which is used to describe the dynamics of a particle in a fluid with drag and fluctuations. This model is a two-dimensional first-order model similar to the one proposed nearly half a century ago by two physicists or applied mathematicians, which implies it has a historical significance in its contribution to physical theories. Additionally, the model and equation are going to be used with the Bohr model of the hydrogen atom to provide insights into atomic stability, atomic size, and electron binding energy within the atom, which is crucial for understanding atomic physics and quantum mechanics.
The Fokker-Planck equation includes a drift term that accounts for the deceleration of the particle due to drag, and a diffusion term representing the random walk of the particle's momentum due to fluctuations. The context provided suggests that these concepts are being applied to explain the behavior of a charged particle and that the coefficients from the linear model can be combined with operating parameters to derive specific equations for this system. This points to an advanced-level discussion suitable for College-level Physics courses where students are expected to have a foundation in these theories.
a) Work out the size of AOD.
b) Work out the size of angle ABC and give a reason for your answer.
Thanks in advance :)
Answer:
ABC = 31
Step-by-step explanation:
Angle AOC and ABC have the angle theorem: the angle subtended at the centre of the circle is double the angle at the circumference. Its quite hard to realise the layout, because angle AOC isn't between points A and C. If angle AOC moved to the right side of line AB, it would be easier to see. Of course we cannot do this, otherwise angle AOC wouldn't be the middle anymore. Hope this helped
(a). The angle AOD is 62 degrees.
(b). The angle ABC is 31 degrees.
(a). From given diagram, It is observed that triangle AOD is a right angle triangle.
The sum of all three angles in triangle is equal to 180 degrees.
[tex]\angle A +\angle O + \angle D = 180\\\\90 +\angle AOD +28=180\\\\\angle AOD=180-90-28=62[/tex]
(b). The central angle theorem states that the angle subtended by an arc at the center of the circle is double the angle subtended at any point on the circumference of the circle.
[tex]\angle ABC = \frac{1}{2} \angle AOD\\ \\\angle ABC=\frac{1}{2}*62=31[/tex]

● Frank drove his car at an average speed of 43 mph for 2.5 hours.
Using your new equation, determine the distance, d, Frank drove.
Show all the steps.
Answer:
107.5 miles
Step-by-step explanation:
We can use the formula d = rt (distance = rate · time) to find the distance travelled.
We know that,
r = 43 mph
t = 2.5 hrs
Plug these values into the formula to get your answer.
43 · 2.5 = 107.5 miles
Answer:
Frank drove a total of about 107 miles.
Step-by-step explanation:
Okay...
2.5 hours at 43 miles per hour.
43 x 2 = 86
and for .50 we can say half which is about 21 or 22 miles.
So,
86 + 21 = 107

1. A number cube is rolled 24 times and lands on 2 four times and on 6 three times.
a. Find the experimental probability of landing on a 2.
b. Find the experimental probability of not landing on a 6.
c. Compare the experimental probability you found in part a to its theoretical probability.
d. Compare the experimental probability you found in part b to its theoretical probability.
How do you show work?
a. The experimental probability of landing on a 2 is 1/6.
b. The experimental probability of not landing on a 6 is 5/6.
c. The experimental probability of landing on a 2 (1/6) closely aligns with its theoretical probability (1/6).
d. The experimental probability of not landing on a 6 (5/6) also closely aligns with its theoretical probability (5/6).
Explanation:a. To find the experimental probability of landing on a 2, divide the number of times it landed on a 2 (four times) by the total number of trials (24 times). Thus, [tex]\( P(\text{landing on 2}) = \frac{4}{24} = \frac{1}{6} \).[/tex]
b. To find the experimental probability of not landing on a 6, subtract the experimental probability of landing on a 6 (3/24) from 1. Thus,[tex]\( P(\text{not landing on 6}) = 1 - \frac{3}{24} = \frac{5}{6} \).[/tex]
c. Comparing the experimental probability of landing on a 2 (1/6) with its theoretical probability (1/6) shows that they closely match, indicating a consistent outcome.
d. Comparing the experimental probability of not landing on a 6 (5/6) with its theoretical probability (5/6) reveals a close alignment, confirming the reliability of the experimental results.
In summary, experimental probabilities were determined by dividing the favorable outcomes by the total number of trials. The comparison with theoretical probabilities indicates the reliability of the experimental data, as the values closely match in both cases. This alignment strengthens the validity of the experimental results and the predictive power of theoretical probabilities in this scenario.

Joshua tutored Eric Ben.
Joshua earned more on Saturday than on Sunday.
Joshua tutored Eric on Saturday and Sunday to Ben. Joshua earned $4.50 more on Saturday than on Sunday.
Joshua tutored Eric on Saturday and Sunday to Ben.
On Saturday, Joshua charged $12.50 per hour for tutoring, and since he also charged the same rate for guitar lessons, the total earnings were based on the combined time spent on tutoring and guitar lessons.
He added a flat fee of $4.50 for traveling. With a total earning of $35.75, the equation can be set up as follows:
[tex]\[ \text{Total Earnings on Saturday} = (\text{Hourly Rate} \times \text{Total Hours}) + \text{Flat Traveling Fee} \][/tex]
[tex]\[ 35.75 = (12.50 \times \text{Total Hours}) + 4.50 \][/tex]
Solving for the total hours, we find that Joshua spent 2 hours tutoring and giving guitar lessons on Saturday.
On Sunday, Joshua spent 0.5 hours giving guitar lessons and the remaining time tutoring Ben. Without a flat rate for traveling, the total earnings on Sunday were $31.25. Joshua's hourly rate remains $12.50. The equation can be expressed as:
[tex]\[ \text{Total Earnings on Sunday} = (\text{Hourly Rate} \times \text{Total Hours}) \][/tex]
[tex]\[ 31.25 = (12.50 \times \text{Total Hours}) \][/tex]
Solving for the total hours, we find that Joshua spent 2.5 hours tutoring and giving guitar lessons on Sunday.
Therefore, Joshua tutored Eric for 2 hours and gave guitar lessons for the remaining time on Saturday. On Sunday, he gave guitar lessons for 0.5 hours and tutored Ben for 2.5 hours.
Joshua earned $4.50 more on Saturday than on Sunday.
