Answer:
1.5x10^-18
Step-by-step explanation:
8.4x10^9 / x = 5.6x10^27
You could make a proportion:
x(5.6 x 10^27)= 8.4x10^9
divide both sides by 5.6x10^27
x=1.5x10^-18
Answer:
[tex]1.5*10^{-18}[/tex]
Step-by-step explanation:
The question is in the format [tex]\frac{8.4*10^9}{n}=5.6*10^{27}[/tex]
First multiply both sides by n and then divide both sides by the number in scientific notation on the right.
[tex]\frac{8.4*10^9}{5.6*10^{27}}=n[/tex]
We can think of this problem as [tex]\frac{8.4}{5.6}*\frac{10^{9}}{10^{27}}=\frac{8.4}{5.6}*10^9*10^{-27}[/tex]
When dividing like-terms, we subtract their powers (or we can get the multiplicative inverse and add the powers).
We end up with [tex]1.5*10^{-18}[/tex]

The demand for good X has been estimated by Qxd=12-3Px + 3Py. Suppose that good X sells at $2 per unit and good Y sells for $1 per unit. Calculate the own price elasticity. Multiple Choice -0.2 -0.67
Therefore, the own price elasticity of good X is approximately -0.67.(rounded to 2 decimal places)
To calculate the own price elasticity of good X, we need to use the formula:
Own Price Elasticity = (% change in quantity demanded) / (% change in price)
Given that the price of good X is $2 per unit, we can substitute the price (Px) into the demand equation:
Qxd = 12 - 3Px + 3Py
Substituting Px = $2 and Py = $1 into the equation, we get:
Qxd = 12 - 3(2) + 3(1)
= 12 - 6 + 3
= 9
Now, let's calculate the quantity demanded when the price changes by a small amount, let's say $0.10. We can substitute Px = $2.10 into the demand equation:
Qxd' = 12 - 3(2.10) + 3(1)
= 12 - 6.30 + 3
= 8.70
Using these values, we can calculate the percentage change in quantity demanded and the percentage change in price:
% change in quantity demanded = (Qxd' - Qxd) / Qxd * 100
= (8.70 - 9) / 9 * 100
= -0.30 / 9 * 100
= -3.33% (rounded to 2 decimal places)
% change in price = (Px' - Px) / Px * 100
= (2.10 - 2) / 2 * 100
= 0.10 / 2 * 100
= 5%
Now, let's calculate the own price elasticity using the formula:
Own Price Elasticity = (% change in quantity demanded) / (% change inprice)
= -3.33% / 5%
= -0.67 (rounded to 2 decimal places)

1. Let the market demand function for two companies namely, Coca-Cola and Pepsi be given by; Q(p) = 200 - P where Q = 9₁ +92. The cost function for each of the two firms in the industry is C(qi) = 2
The total Quantity demanded is:Q = 9 * (200 - P) + 92On simplifying this expression, we get:Q = 1828 - 9P
Substituting this value of Q in the profit function, we get:Pi = (198 - (1828 - 9P)) * qiOn
simplifying this expression, we get:Pi = (10P - 1630) * qi
This is the profit function for each firm in the industry.
The given market demand function for Coca-Cola and Pepsi is Q(p) = 200 - P. Here, Q denotes the total quantity demanded and P represents the price of the product.
The cost function for each of the two firms is C(qi) = 2q_i where q_i denotes the quantity produced by the ith firm.
Now, we need to determine the profit function for each firm in the industry.
To find out the profit function for each firm, we need to calculate the revenue function and subtract the cost function from it.The revenue function is the product of price and quantity. Therefore, the revenue function for both firms is:Ri = p * qi where Ri is the revenue of ith firm.
The price of each firm is determined by the market demand function as follows:p = 200 - QSubstituting this value of p in the above expression, we get:Ri = (200 - Q) * qi
Now, we need to calculate the profit function for each firm. It is given by the following expression:Pi = Ri - Ci where Pi is the profit of ith firm and Ci is the cost of production of ith firm. Substituting the value of Ri and Ci in the above equation, we get:
Pi = (200 - Q) * qi - 2qiOn simplifying this expression, we get:Pi = (198 - Q) * qiThis is the profit function for both firms in the industry. It is a function of quantity produced by each firm (qi) and total quantity demanded (Q). Hence, the profit of each firm depends on the total quantity demanded and the quantity produced by the firm.
The given demand function is Q(p) = 200 - P. Here, we are given Q = 9₁ + 92.
Therefore, the total quantity demanded is:Q = 9 * (200 - P) + 92On simplifying this expression, we get:Q = 1828 - 9P
Substituting this value of Q in the profit function, we get:Pi = (198 - (1828 - 9P)) * qiOn
simplifying this expression, we get:Pi = (10P - 1630) * qi
This is the profit function for each firm in the industry.

Suppose that you began a one-year study of tuberculosis (TB) in a subsidized housing community in the Lower East Side of New York City on January 1st, 2020. You enrolled 500 residents in your study and checked on their TB status on a monthly basis. At the start of your study on January 1st, you screened all 500 residents. Upon screening, you found that 20 of the healthy residents were immigrants who were vaccinated for TB and so were not at risk. Another 30 residents already had existing cases of TB on January 1st. On February 1st, 5 residents developed TB. On April 1st, 5 more residents developed TB. On June 1st, 10 healthy residents moved away from New York City were lost to follow-up. On July 1st, 10 of the residents who had existing TB on January 1st died from their disease. The study ended on December 31, 2010. Assume that once a person gets TB, they have it for the duration of the study, and assume that all remaining residents stayed healthy and were not lost to follow-up.
Using the same TB scenario, what was the case-fatality rate among residents with TB over the course of the year?
25.0%
14.3%
20.0%
None of the above
The case-fatality rate among residents with TB over the course of the year is approximately 33.3%. None of the answer choices provided (25.0%, 14.3%, 20.0%) match this calculated value, so the correct answer is "None of the above."
The case-fatality rate among residents with TB over the course of the year can be calculated by dividing the number of residents who died from TB by the total number of residents with TB at the start of the study. Let's calculate it based on the given information.
On January 1st, there were 30 residents with existing cases of TB. On July 1st, 10 of these residents died from their disease.
Case-Fatality Rate = (Number of TB deaths / Number of residents with TB) * 100%
Case-Fatality Rate = (10 / 30) * 100% ≈ 33.3%
Therefore, based on the given information, the case-fatality rate among residents with TB over the course of the year is approximately 33.3%. None of the answer choices provided (25.0%, 14.3%, 20.0%) match this calculated value, so the correct answer is "None of the above."

In a cantilever beam system, where a beam carries an end mass, the equivalent mass is the combined mass of the beam and the end mass. The equivalent mass is calculated by adding the mass of the beam and the end mass. In the context of piston travel diagrams, the gas pressure force depends on the piston acceleration, crank radius, and piston velocity, with the piston travel being influenced by the crank angle, crank radius, and connected rod length.
In a cantilever beam system, the equivalent mass is determined by adding the mass of the beam to the mass of the end mass. In the given example, the beam has a mass of 5 kg, and the end mass is 3.85 kg. Therefore, the equivalent mass of the system is 5 kg + 3.85 kg = 8.85 kg.
Regarding piston travel diagrams, the gas pressure force acting on the piston depends on several factors. The piston acceleration, which represents the rate of change of piston velocity with respect to time, influences the gas pressure force. A higher acceleration results in a greater gas pressure force acting on the piston.
The crank radius, which is the distance from the center of the crankshaft to the point where the connecting rod is attached, also affects the gas pressure force. The piston velocity, which is the rate at which the piston moves, is influenced by the crank radius. A larger crank radius leads to higher piston velocity and, consequently, greater gas pressure force.
The piston travel, representing the linear displacement of the piston, is influenced by the crank angle, crank radius, and connected rod length. These factors determine the motion of the piston and the overall behavior of the system.
In summary, the equivalent mass in a cantilever beam system is obtained by adding the mass of the beam and the end mass. In piston travel diagrams, the gas pressure force depends on the piston acceleration, crank radius, and piston velocity. The piston travel is influenced by the crank angle, crank radius, and connected rod length.

Morgan purchased a new car, which depreciates over time. Morgan’s car depreciates
according to the function y=62,150( . 9999)xx, where x represents the number of months since
the car was purchased. What is the range of the exponential function y based on its equation
and the context of the problem?
The range of the exponential function y based on its equation and the context of the problem is a set of positive real numbers less than the initial value of 62,150, representing the decreasing value of the car over time.
The given function represents the depreciation of Morgan's car over time, where x represents the number of months since the car was purchased. The function is y = 62,150 * (0.9999)^x.
To determine the range of the exponential function y, we need to consider the context of the problem. In this case, the range represents the possible values for the car's depreciation, or the value of y.
The base of the exponential function is 0.9999, which is less than 1. When a value between 0 and 1 is raised to a positive power, it decreases exponentially as the power increases. Therefore, as x (the number of months) increases, the value of y (the car's depreciation) decreases.
Since the base is less than 1, the range of the exponential function y is also less than the initial value of 62,150. As x approaches infinity, the value of y approaches 0, but it will never actually reach 0.
In practical terms, the range of the exponential function represents the decreasing value of the car over time. It indicates that the car's depreciation is continuous and will approach zero but will never completely reach zero.
