A power company calculates a person's monthly bill from the number of
kilowatt-hours (kWh), x, used.
The function b(z) = {
0.152,
0.10 (x - 360) + 54, > 360
<< 360
determines
the bill.
How much is the bill for a person who uses 560 kWh in a month?
Answer:
0.152
Explanation:
The given function is:
b(x) = {0.152x, x ≤ 360
{0.10(x - 360) + 54, x > 360
What does the given problem involve at ?The given problem involves a function b(x) that calculates a person's monthly bill from the number of kilowatt-hours (kWh) used. The function has two parts: one for the first 360 kWh and another for any additional kWh used.
For the first 360 kWh, the bill is a flat rate of $0.152 per kWh, which means the cost is 0.152 × 360 = $54.72.
For any additional kWh used beyond the first 360, the cost is $0.10 per kWh. So for the remaining 200 kWh used (560 - 360), the cost is 0.10 × 200 = $20.
Therefore, the total bill for a person who uses 560 kWh in a month is the sum of the two costs: $54.72 + $20 = $74.72.
We need to find the bill for a person who uses 560 kWh in a month.
Since 560 is greater than 360, we will use the second part of the function.
b(x) = 0.10(x - 360) + 54
b(560) = 0.10(560 - 360) + 54
b(560) = 0.10(200) + 54
b(560) = 20 + 54
b(560) = 74
Therefore, the bill for a person who uses 560 kWh in a month is $74.

According to the video on personal hygiene, hepatitis A is a commonly transmitted bacterial infection caused by poor hygiene.
Answer:
thats true
Explanation:
Hepatitis A is actually a viral infection, not a bacterial one. It is primarily transmitted through the ingestion of contaminated food or water.
Poor hygiene, particularly inadequate handwashing after using the restroom, can contribute to the spread of the virus. However, it's important to note that hepatitis A is caused by the hepatitis A virus (HAV), not bacteria. It affects the liver and can lead to symptoms such as jaundice, fatigue, abdominal pain, and nausea.
If you have any concerns about hepatitis A or personal hygiene, it's a good idea to consult with a medical professional for accurate and up-to-date information.

What are the 4 types of teeth we have in our mouths?
Incisors: Incisors are the sharp teeth at the front of the mouth that bite into food and cut it into smaller pieces. They are flat with a thin edge. They are also called anterior teeth.
Both children and adults have eight incisors — four central incisors at the front of the mouth, two on each row, with one lateral incisor positioned on either side of them.
Canines: Canines are the sharp, pointed teeth that sit next to the incisors and look like fangs. Dentists also call them cuspids or eyeteeth. Canines are the longest of all the teeth, and people use them to tear food.
Both children and adults have four canines. Children usually get their first permanent canines between the ages of 9 and 12. The lower canines tend to come through slightly before those in the upper jaw.
Premolars: Premolars, or bicuspids, are bigger than the incisors and canines. They have many ridges and help chew and grind up food. Adults have eight premolars. The first and second premolars are the molars that sit next to the canines.
Young children do not have premolar teeth. These first appear as permanent teeth when children are 10–12 years old.
Molars: Molars are the biggest of all the teeth. They have a large, flat surface with ridges that allow them to chew food and grind it up. Adults have 12 permanent molars — six on the bottom and top jaw, and children have eight primary molars.
The last molars to erupt are wisdom teeth, or third molars, which usually come through between the ages of 17–21. These sit at the end of the row of teeth, in the far corners of the jaw. Some people do not have all four wisdom teeth, or the teeth may stay unerupted in the bone and never appear in the mouth.
Sometimes wisdom teeth can become impacted, which means they can become trapped under the gum and are unable to come through properly.
Wisdom teeth that only come through halfway or are in the wrong position can increase the risk for infection or damage in surrounding areas. It is essential to see a dentist if people have any issues with their wisdom teeth.
People may experience mild discomfort when their wisdom teeth start pushing through the gums, but anyone feeling a lot of pain or has swelling should see a dentist.
A dentist may need to remove wisdom teeth if a person has tooth decay, pain, or an infection. People do not need these teeth for chewing, and they are difficult to keep clean because of their position far back in the mouth.

How can providing first aid care be hazardous for the person providing the assistance?
Providing first aid can be hazardous to the provider if the accident victim is infected with a communicable disease. Many body fluids, such as blood and lymph, can serve as vectors for disease transmission. If first aid responders come into direct contact with body fluids while providing aid, they may be at risk. In addition, if the environmental conditions that led to the accident in the first place still exist, then the responders may be in the same danger for injury as the person being assisted.

Find the low and high target heart rate zones for a 46-year-old teacher from El Cerrito Middle School with a resting heart rate of 78bpm.
The low and high target heart rate zones for the 46-year-old teacher with a resting heart rate of 78bpm are;
Low target heart rate = 87 bpm
High target heart rate = 131 bpm
We are told that the resting heart rate of the 46 year old teacher is 78 bpm.
Now, the formula for calculation of the estimated maximum age-related heart rate is;
Maximum age related heart rate = 220 – person's age
For this 46 year old man;
Maximum age related heart rate = 220 - 46
Maximum age related heart rate = 174 bpm
Now. since his resting heart rate is average at 78 bpm, then the low and high target heart rate will be gotten from the formula;
Low target heart rate = 50% × Maximum age related heart rate
High target heart rate = 75% × Maximum age related heart rate
Thus;
Low target heart rate = 50% × 174
Low target heart rate = 87 bpm
High target heart rate = 75% × 174
High target heart rate ≈ 131 bpm
