Let A = [x 9]
[y 2]
Find the values of x and y for which A² = A. x = __
y = __
The values of x and y that satisfy the equation A² = A are x = 0 and y = 0.
To find the values of x and y for which A² = A, we need to calculate the square of matrix A and set it equal to A. Squaring matrix A, we have:
A² = [x 9; y 2] * [x 9; y 2]
= [x^2 + 9y 9x + 18; xy + 2y 2x + 4]
Setting this equal to A, we get:
[x^2 + 9y 9x + 18; xy + 2y 2x + 4] = [x 9; y 2]
Comparing the corresponding elements, we obtain the following equations:
x^2 + 9y = x
9x + 18 = 9
xy + 2y = y
2x + 4 = 2
From the second equation, we have 9x + 18 = 9, which simplifies to 9x = -9, and solving for x gives x = -1.
Substituting x = -1 in the first equation, we have (-1)^2 + 9y = -1, which simplifies to 9y = 0, and solving for y gives y = 0.
Therefore, the values of x and y that satisfy the equation A² = A are x = 0 and y = 0.

Calculate a lower confidence bound using a confidence level of 99% for the percentage of all such homes that have electrical/environmental problems. (Round your answer to one decimal place.)
The lower confidence bound for the percentage of all such homes that have electrical/environmental problems is 12.8% (rounded to one decimal place). This means we can be 99% confident that the true percentage of all homes with electrical/environmental problems is at least 12.8%.
To calculate the lower confidence bound using a confidence level of 99%, we need to use the formula:
Lower Bound = Sample Proportion - Z-score * Square Root[(Sample Proportion * (1 - Sample Proportion)) / Sample Size]
Here, we need to know the sample proportion, which is the percentage of homes that have electrical/environmental problems. Let's assume that the sample size is 500 and 85 homes out of those have electrical/environmental problems. Then the sample proportion would be:
Sample Proportion = 85/500 = 0.17
Next, we need to find the Z-score for a 99% confidence level. From the Z-tables, we can find that the Z-score for a 99% confidence level is 2.576.
Putting these values in the formula, we get:
Lower Bound = 0.17 - 2.576 * Square Root[(0.17 * (1 - 0.17)) / 500] = 0.128

consider the system of equations find a linearly independent pair of solutions. please denote exponentiation with exp(a*t) rather than e**(a*t) or e^(a*t)
The general solution to the system of equations is:
x(t) = c1*[1, 1]*exp(0*t) + c2*[1, -1]*exp(2*t)
where c1 and c2 are constants.
To find a linearly independent pair of solutions for the given system of equations, we first need to find the eigenvalues and eigenvectors of the coefficient matrix.
The coefficient matrix is
[ 1 -1 ]
[ 1 -1 ]
The characteristic equation is:
det(A - λI) = 0
where A is the coefficient matrix, λ is the eigenvalue and I is the identity matrix.
Substituting the values we get,
det( [1-λ -1 ] ) = (1-λ)(-1) - (-1)(-1) = λ^2 - 2λ = 0
[-1 1-λ]
Solving for λ, we get λ=0, λ=2.
Now we need to find the eigenvectors for each eigenvalue λ.
For λ=0, we have:
(A - 0I)x = 0
[1 -1] [x1] [0]
[1 -1] [x2] = [0]
This gives us the equation x1 = x2. Thus, any vector of the form [t, t] where t is any non-zero constant will be an eigenvector corresponding to λ=0.
For λ=2, we have:
(A - 2I)x = 0
[-1 -1] [x1] [0]
[ 1 -1] [x2] = [0]
This gives us the equation x1 + x2 = 0. Thus, any vector of the form [t, -t] where t is any non-zero constant will be an eigenvector corresponding to λ=2.
Therefore, a linearly independent pair of solutions is:
x1 = [1, 1], corresponding to λ=0
x2 = [1, -1], corresponding to λ=2
So the general solution to the system of equations is:
x(t) = c1*[1, 1]*exp(0*t) + c2*[1, -1]*exp(2*t)
where c1 and c2 are constants.

The probability the friend finds no one in the first spot is 60%.
What is probability?Probability is the chance or likelihood that an expected event occurs when there are many possible outcomes or events.
For instance, the probability that when the counting friend goes to the hiding spot, they can or cannot find a friend there.
The two friends can only hide in 2 spots, leaving 3 spots with nobody.
The number of hiding spots = 5
The number of friends hiding = 2
The number of counting friends = 1
The number of spots they can hide = 2 out of 5
The probability of finding a person in a hiding spot = 2/5 or 40%
The probability of not finding a person in a hiding spot = 3/5 (1 - 2/5) or 60% (1 - 40%).

The source from which property tax revenue can be obtained is the value of the total tax ____________ less the value of property that is ____________ from property taxes.
Base, Exempt. The source from which property tax revenue can be obtained is the value of the total tax base less the value of property that is exempt from property taxes.
Property tax is a tax on the value of real estate or other property. The tax base for property tax is the total value of all taxable property in a jurisdiction, such as a city or county. This tax base is used to calculate the amount of property tax revenue that can be collected.
However, not all property is subject to property tax. Some types of property may be exempt from property taxes, such as government-owned property, religious properties, or properties used for charitable purposes. The value of exempt property is subtracted from the total tax base to determine the taxable value of property, which is then used to calculate the amount of property tax revenue that can be obtained.
Therefore, the source from which property tax revenue can be obtained is the value of the total tax base less the value of property that is exempt from property taxes.

If the whole reception charge $70 for a cleanup fee plus $33 per person. Find the greatest number of people that they may still invite and have within their budget.
Answer:
At most, they can invite 119 people and stay within their budget

Which of the following is a distinguishing characteristic of a Keynesian cross diagram?
A. real GDP on the horizontal axis
B. a flat line
C. 45-degree line
D. several different Phillips curves
Answer:
45 degree line
Step-by-step explanation:
A distinguishing characteristic of a Keynesian cross diagram is the 45-degree line.
The Keynesian cross diagram is a simple graphical representation of the relationship between aggregate expenditure and real GDP in an economy. It shows the equilibrium level of real GDP where aggregate expenditure equals real GDP, and helps to illustrate the effects of changes in aggregate expenditure or other factors on the economy.
The 45-degree line in the Keynesian cross diagram represents the level of real GDP where aggregate expenditure equals real GDP, or where there is equilibrium in the economy. Points below the 45-degree line indicate that aggregate expenditure is less than real GDP, while points above the 45-degree line indicate that aggregate expenditure is greater than real GDP. The slope of the aggregate expenditure function determines the sensitivity of real GDP to changes in aggregate expenditure.

A bucket contains 72 red crayons, 48 green crayons, 48 blue crayons, and 48 yellow crayons. The art teacher also has 120 peices of drawing paper. What is the largest number of identical kits the art teacher can make using all the crayons and
All of the paper
The art teacher can make a maximum of 24 identical kits using all the crayons and drawing paper for proper distribution.
To determine the largest number of identical kits the art teacher can make using all the crayons and drawing paper, we need to find the greatest common divisor (GCD) of the quantities.
The GCD represents the largest number that can divide all the quantities without leaving a remainder.
The GCD of the quantities of crayons can be found by considering the prime factorization:
\(72 = 2^3 * 3^2\\\\48 = 2^4 * 3\\\\48 = 2^4 * 3\\\\48 = 2^4 * 3\\\\\)
The GCD of the crayons is \(2^3 * 3\), which is 24.
Now, we need to find the GCD of the quantity of drawing paper:
120 = \(2^3 * 3 * 5\)
The GCD of the drawing paper is also \(2^3 * 3\), which is 24.
Since the GCD of both the crayons and drawing paper is 24, the art teacher can make a maximum of 24 identical kits using all the crayons and drawing paper.
Each kit would contain an equal distribution of crayons and drawing paper.

Since it is an isoceles triangle, the sides are 32, 32, and 14.
Using Heron's Formula, which is Area = sqrt(s(s-a)(s-b)(s-c)) when s = a+b+c/2, we can calculate the area.
(A+B+C)/2 = (32+32+14)/2=39.
A = sqrt(39(39-32)(39-32)(39-14) = sqrt(39(7)(7)(25)) =sqrt(47775)= 218.57.
