A coin when left from certain height starts moving towards the earth under the influence of......... *
Answers
When a coin is left from a certain height starts moving towards the Earth under the influence of gravity.
Gravity is a term from physics that refers to the natural phenomenon that causes objects with mass to be attracted to each other. On Earth, gravity is equivalent to 9.8 m / s² and this makes objects fall towards the ground.
According to the above, if a coin is dropped from a certain height it will go towards the ground because gravity will attract it and it will take an acceleration of 9.8 m / s².
According to the above, the answer is gravity, because this is the natural phenomenon that influences the direction the coin takes.

if x is uniformly distributed over (a, b), find a random variable y linear in x that is uniformly distributed over (0, 1).
Answers
We can use the transformation y = (x - a) / (b - a) to generate a random variable y that is linear in x and uniformly distributed over (0, 1).
To find a random variable y that is linear in x and uniformly distributed over (0, 1), we can use the following transformation:
y = (x - a) / (b - a)
This transformation maps the interval (a, b) to the interval (0, 1) and ensures that the distribution of y is uniform.
To see why this is the case, we can use the formula for the probability density function (pdf) of a uniform distribution:
f(x) = 1 / (b - a)
This means that the probability of x being between any two values c and d is proportional to the length of the interval (d - c) and is given by:
P(c < x < d) = (d - c) / (b - a)
Now, let's find the pdf of y using the transformation above:
F(y) = P(y < Y) = P((x - a) / (b - a) < y) = P(x < (b - a) * y + a)
We can differentiate this to get the pdf of y:
f(y) = dF(y) / dy = f(x) / (b - a) = 1 / (b - a)
This shows that the distribution of y is indeed uniform over (0, 1).

Use symbolic notation and fractions where needed. Give your answer as point coordinates in the form (*, *, *).) point of intersection: Find the angle between 1₁ and 12. (Use symbolic notation and fractions where needed.) θ =
Answers
The point of intersection is given byr₁ = (212(34/35))i + 7(34/35)j + (−2 + 22(34/35))kr₁ = (2, 2, 2)
To find the point of intersection of the two lines 1₁ and 1₂, follow these steps:
Step 1: Equate the components of the two vectors212t₁ = -2t₂
(i)7t₁ = 2 + 1₂
(ii)-2 + 22t₁ = 4t₂
(iii) Step 2: Solve the simultaneous equations obtained in step 1 to get values of t₁ and t₂.
Multiplying equation (i) by -7/1061t₁ = 7/5t₂ (iv) Substituting this value of t₂ in equation (ii),7t₁ = 2 + 1(7/5t₂) = 17/5t₁ = 34/35 Therefore, t₁ = 34/35.
Substituting this value of t₁ in equation (iii),-2 + 22(34/35) = 4t₂T₂ = -114/140 = -57/70 Therefore, t₂ = -57/70.
Hence the point of intersection is given byr₁ = (212(34/35))i + 7(34/35)j + (−2 + 22(34/35))kr₁ = (2, 2, 2)
The answer for the angle between 1₁ and 12 is shown below: Angle between 1₁ and 1₂ is given by:θ = cosθ = 1₁.1₂/|1₁||1₂| where 1₁.1₂ is the dot product of vectors 1₁ and 1₂ and |1₁| and |1₂| are their magnitudes.1₁.1₂ = (212t₁ × -2t₂) + (7t₁ × (2 + t₂)) + ((-2 + 22t₁) × 4t₂)= -424t₁t₂ + 14t₁ + 8t₂ - 8 + 88t₁t₂= 102t₁t₂ + 14t₁ + 8t₂ - 8|1₁| = √(212² + 7² + 22²) = √(45181) = 212√2|1₂| = √((-2)² + (2 + 1₂)² + 4²) = √(1₂² + 24) = √(1₂² + 24)cosθ = 1169/(212√2√(1₂² + 24))θ = cos⁻¹(1169/(212√2√(1₂² + 24))\)

Step-by-step explanation:

What is y=1/2x+4 in standard form?
Answers
===========================================
Explanation:
Multiply both sides by 2 to clear out the fraction
y = (1/2)x+4
2y = 2[ (1/2)x + 4 ]
2y = 2*(1/2)x + 2*4
2y = x + 8
Then move the x term over to the left side
2y = x+8
2y-x = 8
-x+2y = 8
Optionally we can multiply both sides by -1
-x+2y = 8
-1*(-x+2y) = -1*8
x-2y = -8
This is in standard form Ax+By = C with A = 1, B = -2, C = -8
The reason why I multiplied both sides by -1 was to make A > 0 which is what some textbooks use as convention. Of course -x+2y = 8 is equally valid too.

Suppose that in 2018 NCSSM used 60,000 sheets of paper in the printers. Due to the growing use of computers and the Sustainability Initiative, the use of paper has been decreasing since then at the rate of 2.25% each year. a) [3 pts) How much paper will be used next year (2023)? Write the equation(s) used for solving the problem. b) [4 pts] Assuming that the paper use continues to decrease at the same rate, how many total sheets of paper will be used from 2018 (including 2018) through the end of 2030? Show all work needed to solve the problem including the equation used for solving the problem.
Answers
The answer to part a) is that next year, in 2023, NCSSM will use approximately 55,485 sheets of paper. In part b), total of approximately 363,353 sheets of paper will be used from 2018 through the end of 2030.
a) To calculate the paper used in 2023, we start with the initial amount used in 2018, which is given as 60,000 sheets of paper. We then need to calculate the decrease in paper use over the years. The rate of decrease is given as 2.25%, which can be written as 0.0225 in decimal form. To find the paper used in 2023, we multiply the initial amount by (1 - rate of decrease)^5, since five years have passed from 2018 to 2023.
b) To calculate the total paper used from 2018 to 2030, we need to sum up the paper used for each year in that time period. We start with the initial amount used in 2018, which is 60,000 sheets. Then we calculate the paper used each year using the same formula as in part a), multiplying the initial amount by (1 - rate of decrease)^n, where n represents the number of years since 2018. We sum up these values for the years 2018 to 2030, which is a total of 13 years.

- Encourage the use of the incentive spirometer every 2 hours
-Instruct to splint incision when coughing and deep breathing.
-Reposition the client every 2 hours

Step-by-step explanation:
Hope I could help!
In the plan of care to prevent postoperative atelectasis, interventions should not include the use of tobacco products or exposure to secondhand smoke.
The nurse should include several interventions in the plan of care to prevent postoperative atelectasis, but there are specific interventions that should not be included. Atelectasis is the partial or complete collapse of the lung, and preventing it is crucial after surgery. Here are some interventions that should be included:
Incentive Spirometry: The nurse should encourage the client to use an incentive spirometer to promote deep breathing and lung expansion.
Early Ambulation: Encouraging the client to get out of bed and walk as soon as possible after surgery helps improve lung function.
Pain Management: Adequate pain control measures should be in place to ensure the client can take deep breaths without discomfort.
Coughing and Deep Breathing Exercises: The nurse should teach and encourage the client to perform regular coughing and deep breathing exercises to clear the airways and prevent mucus buildup.
Positioning: Proper positioning, such as elevating the head of the bed, can aid lung expansion.
What should not be included in the plan of care is the use of tobacco products or exposure to secondhand smoke, as smoking and smoke exposure are detrimental to lung health and can worsen atelectasis. These should be strictly avoided to prevent postoperative complications.

a) $800
b) $950
c) $650
d) $750
Answers
Without information about the rental agreement and the deposit amount, it is not possible to determine how much Jordan can expect back.
The rental agreement and state laws determine the amount of deposit that can be withheld for cleaning costs, as well as any other deductions that the landlord may make. To determine the amount that Jordan will receive back, it is necessary to review the rental agreement and any applicable state laws.
To solve this question, the following information needs to be considered:
The rental agreement: The rental agreement will detail the terms of the tenancy, including the amount of deposit paid, the purpose of the deposit, and the conditions under which the deposit can be withheld.State laws: Different states have different laws regarding rental deposits, and these laws will dictate what deductions can be made from the deposit and under what circumstances.Cleaning costs: The $100 cleaning cost is a potential deduction from the deposit, but the rental agreement and state laws need to be reviewed to determine if this cost is eligible to be withheld from the deposit.Other deductions: If there are any other deductions, such as unpaid rent or damages, these need to be considered in determining the amount of deposit that Jordan can expect back.Once these factors have been considered, it should be possible to determine how much of the deposit Jordan can expect back.

How to find the value of x?On the image, we can see a right triangle where x represents one of the angles.
We can see that the length of the two catheti are shown, such that the adjacent cathetus is 2.2, and the opposite cathetus is 3.9, then we can use the trigonometric relation:
tan(a) = (opposite cathetus)/(adjacent cathetus)
Then we can write:
tan(x) = 3.9/2.2
Using the inverse tangent function in both sides, we will get:
Atan( tan(x)) = Atan(3.9/2.2)
