Answer:
432 square feet
Step-by-step explanation:
We know perimeter of rectangle is 2(length + width)
we already know that length is 8 yards
and perimeter is 84 feet
we need to find width first
then
we find area of garden by using formula
area of rectangle = length * width
first we need to convert yards into feet as perimeter is in yards
1 yard = 3 feet
8 yards = 3*8 feet = 24 feet
now we plug value of length and perimeter in formula
perimeter = 2(length + width)
84 = 2(24 + width)
84/2 = 24 + width
=> 42 = 24 + width
=> width = 42 - 24 = 18
Thus, width of garden is 18 feet
now
area of Jordan's garden = length * width = 24* 18 feet square
area of Jordan's garden = 432 square feet

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)

243, 192 x 4 - 8 | 16 12 | 4 | 36 | 8 1
It seems that she broke down the number 243,192 into its individual digits (2, 4, 3, 1, 9, and 2) and performed separate calculations for each digit. However, her approach is not mathematically accurate or coherent.
Now, let's translate Rae's answer into a number that can be understood in base 10:
243,192 x 4 - 8 | 16 12 | 4 | 36 | 8 1
If we reassemble the digits without the vertical separators, we get: 8161243681.

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.

2x-4
Answer:
Step-by-step explanation:
Let's call one leg of the triangle "x" and the other leg "2x-4". We can use the Pythagorean theorem to solve for the lengths of the legs:
x^2 + (2x-4)^2 = 10^2
x^2 + 4x^2 - 16x + 16 = 100
5x^2 - 16x - 84 = 0
We can solve this quadratic equation by factoring or using the quadratic formula. Factoring gives us:
(5x + 14)(x - 6) = 0
So x = -14/5 or x = 6. We can discard the negative solution since we're dealing with lengths. Therefore:
x = 6
2x - 4 = 8
The lengths of the legs are 6 feet and 8 feet.

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%

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."

if the equation has infinitely many solutions for x, what is the value of b ?
If the equation has infinitely many solutions for x, the value of b that results in infinitely many solutions for x is b = 5/2.
To determine the value of b in the equation a(x + b) = 4x + 10, we can analyze the conditions that would result in infinitely many solutions for x.
First, let's simplify the equation:
a(x + b) = 4x + 10
Expanding the left side of the equation
ax + ab = 4x + 10
Now, let's rearrange the equation to isolate x:
ax - 4x = 10 - ab
Factor out x on the left side:
x(a - 4) = 10 - ab
For the equation to have infinitely many solutions, the coefficient of x (a - 4) must be zero, because any value of x would satisfy the equation.
Therefore, we have:
a - 4 = 0
Solving for a:
a = 4
Substituting the value of a into the equation:
4 - 4 = 0
0 = 0
The equation holds true, indicating that a = 4 satisfies the condition for infinitely many solutions. Now, we can find the value of b.
Substituting a = 4 into the original equation:
4(x + b) = 4x + 10
Expanding:
4x + 4b = 4x + 10
Since the x terms cancel out, we are left with:
4b = 10
Dividing both sides by 4:
b = 10/4
Simplifying:
b = 5/2
Therefore, the value of b that results in infinitely many solutions for x is b = 5/2.
