A parabola is:
a. half of an ellipse
b. half of a circle
c. half of a triangle
d. half of a hyperbola
Answer:
I'm not 100 percent sure, but I'm pretty sure that it is half of an ellipse.
Explanation:
For one, if you look at a picture of a hyperbola, you can see that it looks like nothing and is nothing compared to the parabola. However, looking at an ellipse, you can clearly see the resemblance between the two.
Once again, I am not 100 percent certain with this answer, so if you have anything to say about it please let me know.
Have a nice day!

Which of the following statements shows the mind of a "fool" when it comes to credit cards
Answer:
1. You get six credit card offers in the mail, and are stoked! You get all the cards.
2. You find a radical website that promises you the cheapest credit cards for students, and believe everything you read on the site.
3. You decide to get your first credit card from an online bank with no local office.
4. You get a credit card without checking how long the "grace period" is.
Explanation:
A person who's easily hoaxed when it comes to getting credit cards shows the mind of a fool. It is very important to be skeptical when getting one or more because credit cards are not all fun and games, but a huge responsibility.
1. Getting six credit cards offer in the mail doesn't necessarily mean you have to get all of them. You need to know which ones have low interest rates and which ones are suitable for you. You also have to know the fees.
2. You don't need to believe everything that is written on internet websites immediately. You have to do more research about the credit card they're offering whether they're actually telling the truth because sometimes, it's just a promotional strategy so people will get one.
3. It is important to get your first credit card from an online bank with a local office. Having a local office makes the company legit. It is also easier to file any complaints about your card through the local office.
4. Checking the "grace period" is important, so you'd know when you're going to pay your credit card dues. It will help you prevent getting charge with overdue fees.
How should you set up your notes when using the Cornell method?
0 with pictures and maps
0 with levels and sublevels
0 with right and left sides
0 with tables and charts
Answer:
With right and left side charts
Explanation:
I was doing research on this exact question, so here is what I have been looking at;
The Cornell method uses a two-column approach. The left column takes up no more than a third of the page and is often referred to as the “cue” or “recall” column. The right column (about two-thirds of the page) is used for taking notes using any of the methods described above or a combination of them. After class or completing the reading, review your notes and write the key ideas and concepts or questions in the left column. You may also include a summary box at the bottom of the page, in which to write a summary of the class or reading in your own words.

When should the shop ventilation fan be turned on?
Answer:
When cars are running
Explanation:
The shop ventilation fan should be turned on when there are smells, dampness, smoke, and other contaminants in the shop environment. Also, when there is excessive temperature and moisture it should be turned on.
What is Ventilation?
Ventilation assists in cooling your attic by pushing away suffocating hot air from within and bringing in cool air from outside. This keeps hot air from entering your home and raises the temperature in your living area, reducing the strain on your air conditioner.
Exhaust fans purify the air by eliminating smells, dampness, smoke, and other contaminants. Also, it avoids Mold that may grow when there is steam and moisture in the air.
Hence, The shop ventilation fan should be turned on when there are smells, dampness, smoke, and other contaminants in the shop environment. Also, when there is excessive temperature and moisture it should be turned on.

Reducing waste in a shop doesn't help eliminate safety hazards for
employees.
A True
B. False
Pleasseeee help
Answer:
False
Explanation:
Waste in the shop such as garbage, can cause air pollution, which causes various respiratory diseases and other adverse health effects on employees, as contaminants are inhaled and absorbed from lungs into other parts of the body.
These toxic substances in air contaminated by waste that are inhaled by employees include carbon dioxide, nitrous oxide and methane.
Thus, reducing waste which constitutes toxic substances helps to eliminate safety hazards for employees.

Explanation:
How many grams of water at 5.00 °C would we need to mix with 140.0 g of water at 85.0 °C to obtain a final temperature of 43.0 °C ?
Answer:
We need 154.737 grams of water at 5 ºC to obtain a final temperature of 43 ºC.
Explanation:
From Thermodynamics we know that mixing processes involve the interaction of substance at different temperatures so that thermal equilibrium is reached by cooling down the substance with highest temperature and heating up the subtance with lowest temperature.
Let suppose that mixing occurs at steady state, that is, that system does not have energy interactions with surroundings. According to the First Law of Thermodynamics, we get that energy interactions are represented by:
[tex]H_{L} + H_{H} -H_{R} = 0[/tex]
[tex]H_{L} + H_{H} = H_{R}[/tex] (Eq. 1)
Where:
[tex]H_{L}[/tex] - Enthalpy of cold water, measured in joules.
[tex]H_{H}[/tex] - Enthalpy of hot water, measured in joules.
[tex]H_{R}[/tex] - Enthalpy of mixed water, measured in joules.
Since there are no phase changes, we can expand formula by using the definition of sensible heat. That is:
[tex]m_{L}\cdot c_{w}\cdot T_{L}+m_{H}\cdot c_{w}\cdot T_{H} = m_{R}\cdot c_{w}\cdot T_{R}[/tex]
[tex]m_{L}\cdot T_{L}+m_{H}\cdot T_{H} = m_{R}\cdot T_{R}[/tex] (Eq. 2)
Where:
[tex]m_{L}[/tex], [tex]m_{H}[/tex], [tex]m_{R}[/tex] - Masses of cold, hot and mixed water, measured in grams.
[tex]c_{w}[/tex] - Specific heat of water, measured in joules per gram-Celsius.
[tex]T_{L}[/tex], [tex]T_{H}[/tex], [tex]T_{R}[/tex] - Temperatures of cold, hot and mixed water, measured in Celsius.
But we know from Principle of Mass Conservation that:
[tex]m_{R} = m_{L}+m_{H}[/tex] (Eq. 3)
Then, we simplify (Eq. 2) and clear the mass of cold water:
[tex]m_{L}\cdot T_{L}+m_{H}\cdot T_{H} = (m_{L}+m_{H})\cdot T_{R}[/tex]
[tex]m_{H}\cdot (T_{H}-T_{R}) = m_{L}\cdot (T_{R}-T_{L})[/tex]
[tex]m_{L} = m_{H}\cdot \left(\frac{T_{H}-T_{R}}{T_{R}-T_{L}} \right)[/tex] (Eq. 4)
If we know that [tex]m_{H} = 140\,g[/tex], [tex]T_{L} = 5\,^{\circ}C[/tex], [tex]T_{R} = 43\,^{\circ}C[/tex] and [tex]T_{H} = 85\,^{\circ}C[/tex], the mass of cold water needed to obtain a final temperature is:
[tex]m_{L} = (140\,g)\cdot \left(\frac{85\,^{\circ}C-43\,^{\circ}C}{43\,^{\circ}C-5\,^{\circ}C} \right)[/tex]
[tex]m_{L} = 154.737\,g[/tex]
We need 154.737 grams of water at 5 ºC to obtain a final temperature of 43 ºC.
