Answers

The general form of the equation for the given circle centered at O(0, 0) is x^2 + y^2 = 41

How to determine the general form of the equation for the given circle centered at O(0, 0)?

The given parameters are

Center = (0, 0)

Point = (4, 5)

Rewrite the given parameters are

(a, b)= (0, 0)

(x, y) = (4, 5)

The general form of the equation for the given circle is represented as:

(x - a)^2 + (y - b)^2 = r^2

Substitute the known values in the above equation to calculate the radius r

(4 - 0)^2 + (5 - 0)^2 = r^2

Evaluate the difference

4^2 + 5^2 = r^2

Evaluate the exponent

16 + 25 = r^2

Evaluate the sum

41= r^2

Rewrite as

r^2 = 41

Substitute r^2 = 41 in (x - a)^2 + (y - b)^2 = r^2

(x - a)^2 + (y - b)^2 = 41

Substitute (a, b)= (0, 0) in (x - a)^2 + (y - b)^2 = 41

(x - 0)^2 + (y - 0)^2 = 41

Evaluate the difference

x^2 + y^2 = 41

Hence, the general form of the equation for the given circle centered at O(0, 0) is x^2 + y^2 = 41

A single die is rolled twice. Find the probability of getting a 1 the first time and a 5 the second time. Express the probability as a simplified fraction.

Answers

The probability of first rolling a 1, then a 5, will be [tex]\frac{1}{36}[/tex].

What is probability?Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true. The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty. The greater the likelihood of an occurrence, the more probable it will occur.

To find the probability of getting a 1 the first time and a 5 the second time:

Probability of getting 1 in 1st time = [tex]\frac{1}{6}[/tex]

Probability of getting 5 in 2nd time = [tex]\frac{1}{6}[/tex]

The probability of first rolling a 1, then a 5, will be = [tex]\frac{1}{6}[/tex] × [tex]\frac{1}{6}[/tex]

[tex]= \frac{1}{36}[/tex]

A cylinder with a base diameter of x units has a volume of πx3 cubic units. a cylinder with a base diameter of x units has a volume of pi x cubed cubic units. which statements about the cylinder are true? select two options.

Answers

The height of the cylinder is 4 x units.

The area of the cylinder’s base is One-fourthπx2 square units .

What is the volume of cylinder?

We know the volume of a cylinder is given by the formula  π r2 h, where r is the radius of the cylinder and h is the height.

Formula for volume of the cylinder

V = r² π h

Volume of the cylinder= πx³

Diameter=x

Radius (r)=diameter/2

       r  =  x/2

     V = r² π h

   πx³=(x/2)² πh

πx³= (x²/4)πh

Divide both sides by π

x³ =(x²/4)h

Make h the subject of the formula

  h = x³ ÷ x²/4

     =x³ ×4 / x²

     =4x³ / x²

     =4 * x * x * x / x * x

  h=4x

Area of the base:

B = r² π

r=x/2

B=(x/2)² * π

 =(x²/4)π

=πx²/4

=1/4(πx²)

Therefore, The area of the cylinder’s base is One-fourthπx2 square units.

Answers

The cross-section of a right rectangular pyramid will be shaped similar to the base, that is, a rectangle. Hence, 4th option is the right choice.

If the peak of the rectangular pyramid is directly above the center of the base, it creates a perpendicular to the base, indicating the height of the pyramid. This type of rectangular pyramid is known as the right rectangular pyramid.

A rectangle is a quadrilateral, that is a closed figure with 4 line segments, with all four interior angles at 90°.

When we slice a right rectangular pyramid vertically down at the red line by a plane, not passing through the vertex, of the pyramid will be a dilated image of its base.

A dilated image is an enlarged or diminished image of the preimage, similar with all angles.

B.

Step-by-step explanation:

Vertex with (2,4) means that the equation will have:

Open downwards means that the a will be negative:

Stretched by a factor of 3 means that the a=3

How are the coordinates of the extreme value and the equation from part B in the form y=(x-h)^2-c related.

Answers

The extreme value of y = (x - h)² - c is the vertex of the equation.

What are extreme values of a function?

The extreme values of a function are either the maximum or minimum values of the function.

The equation of a parabola in vertex form

The equation of a parabola in vertex form with vertex (h', k) is given by

y = a(x - h')² + k and its extreme values are

if a > 0  (h', k) is a minimum point and if a < 0 (h', k) is a maximum point.

Since y = (x - h)² - c is the equation of a parabola in vertex form, comparing with y = a(x - h')² + k,

h = h' -c = k and a = 1.

So, the cooordinates of the vertex of y = (x - h)² - c is (h, -c).

Now, since a = 1 > 0, (h, -c) is a minimum point.

So first equation of line which is passing through point [tex](-1,7)[/tex] is

[tex]y-7=m_{1} (x-(-1))\\y-7=m_{1}(x+1)[/tex].....(a)

Line [tex]$y=-\frac{1}{8}x-1$[/tex] perpendicular to the line (a)

And we know when two lines are perpendicular then

[tex]m_{1} m_{2} =-1[/tex]

So [tex]m_{1} =-1/m_{2}[/tex]

and we know [tex]m_{2} =-1/8[/tex]

So

[tex]m_{1} =-1/\frac{-1}{8} \\=-1*8/-1\\=8[/tex]

The equation of the line is

[tex]y-7=8(x+1)\\y-7=8x+8\\y=8x+8+7\\y=8x+15[/tex]

The fiscal year-end for Brookwood Pines is June 30. You are performing the audit for the 2023 fiscal year end, and the audit is currently in the risk assessment phase. The healthcare industry can be very complicated, especially in the area of billing for services provided. BPH contracts with private physician groups who use the hospital facilities, equipment, and nursing staff to treat patients. The physicians in the private group are not employees of the hospital; they are simply using the hospital facilities to treat patients. For example, a group of urologists have their own practice, separate from the hospital, where they treat patients. If one of these patients needs a surgical procedure that must be done at a hospital, then the attending urologist will approve the paperwork required to admit the patient to BPH. BPH offers inducements to the urologists so they will refer patients to BPH rather than a competing hospital. One of the inducements BPH offers is free office space in the hospital for the doctors to use when they are treating patients in the hospital. After the doctor and hospital services are provided to the patient, the patient and/or the patients insurance company is billed. The doctor will bill for the services he or she provided, and the hospital will bill for the use of hospital facilities and staff. Doctors and hospitals bill using a coding system that is standardized across the healthcare industry and consists of three main code sets: ICD, CPT, and HCPCS. Using a coding system is more efficient and data-friendly compared to writing a narrative about the procedures performed. However, the coding system is very complex, with thousands of different codes for medical procedures and diagnoses. To complicate matters even more, for patients who are covered by government-sponsored Medicare or Medicaid, doctors and hospitals must adhere to complicated government regulations surrounding billings to Medicare and Medicaid. As healthcare costs continue to rise each year, BPH administrators struggle to maintain consistent profitability. They look for ways to keep costs low and also to collect outstanding payments from patients and insurance companies as quickly as possible. In addition, BPH must have a strong risk management team to handle unique situations that may occur in hospitals such as malpractice lawsuits and periodic inspections by the state regulators. Negative publicity for BPH could lead to decreased revenues if physicians decide to contract with a competing hospital.a) Gather information: You have been assigned to evaluate revenue from patients who are covered by government-sponsored Medicare or Medicaid programs. What questions do you want to ask about BPHs risk assessment controls?b) Analysis: Assume that you are focused on the occurrence of revenue recognized from patients who are covered by government-sponsored Medicare or Medicaid programs. What controls do you expect to be in place regarding this assertion?
