Answer 1

Step-by-step explanation:

if two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.

in terms of this example :

AP × BP = CP × PD

(5+7) × 7 = (14 + PD) × PD

12×7 = 14×PD + PD²

84 = 14×PD + PD²

PD² + 14×PD - 84 = 0

this quadratic equation can be solved by this generic formula :

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = PD

a = 1

b = 14

c = -84

PD = (-14 ± sqrt(196 - 4×1×-84))/(2×1) =

= (-14 ± sqrt(196 + 336))/2 = (-14 ± sqrt(532))/2 =

= (-14 ± sqrt(4×133))/2 = (-14 ± 2×sqrt(133))/2 =

= -7 ± sqrt(133)

PD1 = -7 + sqrt(133) = 4.532562595...

PD2 = -7 - sqrt(133) that is negative and does not make sense for a distance.

I don't know the format you need to have the answer in,

but it is in value

4.532562595... or -7 + sqrt(133)

In a right triangle, one acute angle is 22 degrees less than 3 times the other acute angle. What is the measure of the larger acute angle

Answers

The measure of the acute angles are 62° and 28° .

What is the larger acute angle in a right triangle?The Triangle Angle Sum Theorem states that the sum of all interior angles in a triangle is . Additionally, the Right Triangle Acute Angle Theorem states that the two non-right angles in a right triangle are acute; that is to say, the right angle is always the largest angle in a right triangle.

Let x represent the measure of one of the acute angles of the right angle triangle.

Let y represent the measure of the other acute angle of the right angle triangle.

One of the acute angles in a right triangle measures 22 degrees less than 3 times the other acute angle. This means that

x = 3y - 22

The sum of two acute angles in a right triangle is 90 degrees.

We write as

x + y = 90 - - - - - - - (1)

Substituting x = 3y - 22 into equation 1, it becomes

3y - 22 + y = 90

4y = 90 + 22= 112

y = 112/4 = 28

x = 90 - y = 90 - 28

x = 62

for the simple harmonic motion equation d=2 sin(pi/3t) what is the period

Answers

For the simple harmonic motion equation d=2 sin(pi/3t), the period is 6 seconds.

The period of a simple harmonic motion is the time taken for one complete cycle of the motion. In this equation, d represents the displacement or position of the object at time t. The equation is in the form of sin function with the argument (pi/3)t. The general form of the equation for simple harmonic motion is d=A sin(ωt+φ), where A is the amplitude, ω is the angular frequency, and φ is the phase angle. To determine the period of this motion, we can use the formula T=2π/ω, where T is the period and ω is the angular frequency. In this case, ω=pi/3, so the period is T=2π/(pi/3)=6 seconds (rounded to the nearest second). Therefore, the object completes one full cycle of motion every 6 seconds.

We have various of ways in which we can simplify an equation

for example

simplify: 2x – 4 = 10

soln

2x – 4 = 10

since we are looking for x we need to collect like terms

2x = 10 + 4

2x = 14

Then we will divide both sides by 2 to get x

\(7 \sqrt{7x} = \sqrt{49 \times 7x} \)

We can just remove the √ from both sides to make it easier to see, so

49 × 7x = 343x

Now, let's evaluate the second expression:

A project has an initial cost of $30 million.The project is expected to generate a cash flow of $2.85 million at the end of the first year.All the subsequent cash flows will grow at a constant growth rate of 3.85% forever in future.If the appropriate discount rate of the project is 11%,what is the profitability index of the project? a.1.917 b.1.328 c.1.387 d.1.114 ortcehov e. None of the above

Answers

Profitability index is 1.387. Thus, the correct option is (c) 1.387.

The formula for calculating the profitability index is:

P.I = PV of Future Cash Flows / Initial Investment

Where,

P.I is the profitability index

PV is the present value of future cash flows

The initial investment in the project is $30 million. The cash flow at the end of the first year is $2.85 million.

The present value of cash flows can be calculated using the formula:

PV = CF / (1 + r)ⁿ

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

n is the number of periods

For the first-year cash flow, n = 1, CF = $2.85 million, and r = 11%.

Substituting the values, we get:

PV = 2.85 / (1 + 0.11)¹ = $2.56 million

To calculate the present value of all future cash flows, we can use the formula:

PV = CF / (r - g)

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

g is the constant growth rate

For the subsequent years, CF = $2.85 million, r = 11%, and g = 3.85%.

Substituting the values, we get:

PV = 2.85 / (0.11 - 0.0385) = $39.90 million

The total present value of cash flows is the sum of the present value of the first-year cash flow and the present value of all future cash flows.

PV of future cash flows = $39.90 million + $2.56 million = $42.46 million

Profitability index (P.I) = PV of future cash flows / Initial investment

= 42.46 / 30

= 1.387

Therefore, the correct option is (c) 1.387.

Answer and Explanation: The estimation of the risk level is very difficult as the probability of the deviation is more in such risks. A huge number of people are involved in this type of risk, which makes the estimation more difficult.

Answers

It's also crucial to communicate and involve stakeholders in the risk management process to ensure a comprehensive understanding of the potential risks and their potential impacts.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

You are correct that estimating the risk level can be challenging in situations where the probability of deviation is high. When there are numerous people involved in a particular risk, such as in large-scale projects or complex systems, it can further complicate the estimation process.

Here are a few reasons why estimating risk in such scenarios can be difficult:

1. Uncertainty: High-risk situations often involve a degree of uncertainty. The future outcomes and potential deviations may not be fully known or predictable, making it challenging to quantify the risk accurately.

2. Complex Interdependencies: In situations involving a large number of people or complex systems, there are often intricate interdependencies at play. Changes or deviations in one area can have cascading effects, making it difficult to isolate and assess the specific risk factors involved.

3. Limited Data: Estimating risk relies on historical data, statistical analysis, and expert judgment. However, in novel or rapidly evolving situations, there may be limited historical data available to inform risk assessments. This lack of data can make it challenging to assess the likelihood and impact of potential deviations.

4. Human Factors: Human behavior and decision-making introduce additional uncertainties. In situations involving a large number of people, the actions and decisions of individuals can influence the overall risk profile. Predicting human behavior accurately can be challenging, especially in complex or high-stress environments.

Given these challenges, it is important to employ robust risk management strategies. This includes gathering as much relevant data as possible, engaging subject matter experts, conducting thorough analyses, and continuously monitoring and reassessing risks as the situation evolves. It's also crucial to communicate and involve stakeholders in the risk management process to ensure a comprehensive understanding of the potential risks and their potential impacts.

Step-by-step explanation:

8x - 4y = 16
8x+4y= 16

Answers

Answer:

X = 2, Y = 0

Step-by-step explanation:

Add the two equations together to cancel out -4y and +4y

leaving you with:

8x = 16

8x = 16

divide both sides of the equation by 8 to get x on its own (8x/8 = x, 16/8 =2)

leaving you with:

x = 2

substitute the value of x back into the equation to calculate y (it can be either equation, top or bottom):

8(2) - 4 y = 16

8 x 2 = 16

leaving you with:

16 - 4y = 16

subtract 16 from both sides to get 4y on its own

leaving you with:

-4y = 0

so y = 0, and x = 2

Ms. Regan is making a circular quilt and wants to include a lace pattern


around the outside of the quilt. If the area of the quilt is 28. 26 square feet, how many feet of lace does Ms. Regan need to purchase? (Use 3. 14 for pi. )

Answers

To find out how much lace Ms. Regan needs to purchase, we first need to calculate the circumference of the circular quilt. We know that the area of the quilt is 28.26 square feet, and we can use the formula A = πr^2 to find the radius of the quilt.

28.26 = 3.14 x r^2

r^2 = 9

r = 3

Now that we know the radius is 3 feet, we can use the formula C = 2πr to find the circumference of the quilt.

C = 2 x 3.14 x 3

C = 18.84 feet

Therefore, Ms. Regan needs to purchase 18.84 feet of lace to go around the outside of her circular quilt.

In summary, to find out how much lace Ms. Regan needs to purchase, we need to calculate the circumference of the circular quilt. We do this by first finding the radius using the formula A = πr^2. Once we know the radius, we can use the formula C = 2πr to find the circumference. In this case, the circumference is 18.84 feet, so Ms. Regan needs to purchase that amount of lace.
