Answer:
[tex]\displaystyle{\left(x-4\right)^2 + \left(y-9\right)^2 = 49}[/tex]
Explanation:
The equation of a circle is:
[tex]\displaystyle{\left(x-h\right)^2 + \left(y-k\right)^2 = r^2}[/tex]
Where (h,k) represents the center point and r is the radius. We know the center is at (4,9) and the radius is 7. Thus, substitute in the values:
[tex]\displaystyle{\left(x-4\right)^2 + \left(y-9\right)^2 = 7^2}[/tex]
Which eventually becomes:
[tex]\displaystyle{\left(x-4\right)^2 + \left(y-9\right)^2 = 49}[/tex]
Describe how a fixed water deluge system surrounding a storage
tank would work in the event of a fire.
A fixed water deluge system surrounding a storage tank would work in the event of a fire by quickly extinguishing the fire. In the event of a fire, the deluge system would be activated when the fire detection system is triggered. Water would flow through the network of pipes and nozzles, drenching the fire with water.
What is a fixed water deluge system?A fixed water deluge system is a type of fire protection system that uses open nozzles or sprinklers to disperse large quantities of water on a fire. The system is commonly used in high-hazard locations such as aircraft hangars, offshore drilling rigs, and petrochemical facilities.
How does it work?The deluge system consists of an arrangement of pipes that are connected to a water supply through a control valve. The pipes are arranged in a network around the perimeter of the storage tank and are fitted with open nozzles or sprinklers.
The system is designed to release a large quantity of water when a fire is detected. When the fire detection system is activated, the control valve is opened, and water flows through the pipes and nozzles. The open nozzles or sprinklers drench the fire with water, extinguishing it.
How would it work in the event of a fire?In the event of a fire, the deluge system would be activated when the fire detection system is triggered. Water would flow through the network of pipes and nozzles, drenching the fire with water. The system would quickly extinguish the fire, preventing it from spreading to other areas of the facility.
In summary, a fixed water deluge system surrounding a storage tank would work by quickly extinguishing the fire through the release of large quantities of water from open nozzles or sprinklers when a fire is detected.

From the image or diagram given, note that the measure of angle 1 is also 100°.
How is this so?The theorem that supports the relationship between the measure of an arc and the measure of the central angle is known as the Central Angle Theorem.
According to this theorem,the measure of a central angle in a circle is equal to the measure of the arc it intercepts.
This theorem is based on the fact that in a circle,the ratio of the arc length to the circumference is equal to the ratio of the central angle to the full angle (360 degrees).
Therefore,if the arc measures 100 degrees,the central angle formed by that arc will also measure 100 degrees.

a. Locations only in the southern hemisphere
b. Only divergent plate boundaries
c. Only convergent plate boundaries
d. Only transform plate boundaries
e. Locations only in the northern hemisphere
f. Any of transform, divergent and convergent plate boundaries
Earthquakes can occur at any of the three types of plate boundaries: transform, divergent, and convergent. Their occurrence is not limited to a specific hemisphere but can happen anywhere in the world where tectonic plates interact.
The occurrence of earthquakes is not limited to a specific hemisphere or plate boundary type. Earthquakes can happen at any of the three types of plate boundaries: transform, divergent, and convergent.
Transform plate boundaries occur when two plates slide past each other horizontally. The friction and stress along these boundaries can build up over time, resulting in earthquakes. Famous examples of transform plate boundaries include the San Andreas Fault in California.
Divergent plate boundaries are characterized by plates moving away from each other. As the plates separate, magma rises to fill the gap, forming new crust. The movement of plates and the volcanic activity associated with this process can cause earthquakes. The Mid-Atlantic Ridge is an example of a divergent plate boundary.
Convergent plate boundaries occur when two plates collide or come together. These boundaries can involve subduction, where one plate sinks beneath another, or continental collision, where two continental plates collide. The intense pressure and compression at these boundaries can generate powerful earthquakes. The Pacific Ring of Fire, which surrounds the Pacific Ocean, is known for its numerous convergent plate boundaries and high earthquake activity.
In summary, earthquakes can occur at transform, divergent, and convergent plate boundaries. The occurrence of earthquakes is not limited to a specific hemisphere. Earthquakes can happen anywhere in the world where tectonic plates interact, regardless of their location in the northern or southern hemisphere.

H. W2 break even analysis milled tooth bit drilled 2,461 ft of limestone in 150 rotating hours. Other relevant data for this bit is: Trip time (T) = 8 hrs,Bit cost (B) = $3,000, Rig cost = 900 $/hr It is proposed to replace this bit with an insert-type bit costing 8,500. Calculate the rotating time required of the new bit at breakeven cost for equal penetration rates
The rotating time required for the new insert-type bit to reach the breakeven cost for equal penetration rates is 143.89 hours.
To calculate the rotating time required for the new bit at breakeven cost for equal penetration rates, we can use the concept of break-even analysis. Break-even analysis determines the point at which the cost of two alternatives is equal.
1. Calculate the cost of drilling with the milled tooth bit:
Cost of drilling with the milled tooth bit = Trip time cost + Rotating time cost
Trip time cost = Trip time (T) x Rig cost per hour
= 8 hrs x $900/hr
= $7,200
Rotating time cost = Rotating time x Rig cost per hour
= 150 hrs x $900/hr
= $135,000
Total cost of drilling with the milled tooth bit = Trip time cost + Rotating time cost + Bit cost
= $7,200 + $135,000 + $3,000
= $145,200
2. Set up the equation for the break-even point:
Cost of drilling with the milled tooth bit = Cost of drilling with the insert-type bit
$145,200 = Trip time cost + Rotating time x Rig cost per hour + Cost of the insert-type bit
= $7,200 + (Rotating time x $900) + $8,500
3. Rearrange the equation to solve for the rotating time:
Rotating time x $900 = $145,200 - $7,200 - $8,500
Rotating time x $900 = $129,500
Rotating time = $129,500 / $900
= 143.89 hours
Therefore, the rotating time required for the new insert-type bit to reach the breakeven cost for equal penetration rates is approximately 143.89 hours.
