relationship is directly proportional.

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.

Line a which passes (1, 4) has a constant of proportionality of 4.

Line b runs through (5, 2), with a constant of proportionality of 2/5.

The constant of proportionality is often represented by the letter "k" and it is used in a mathematical relationship known as a proportionality relationship. The proportionality relationship can be written as y = kx, where y and x are the two variables and k is the constant of proportionality.

This means that the value of y is directly proportional to the value of x and is equal to k times the value of x. The value of k can be found by dividing the value of y by the value of x, when the two variables are in proportion.

Line a passes through the (1, 4), therefore:

constant of proportionality = y/x = 4/1 = 4.

Line b passes through the (5, 2), therefore:

constant of proportionality = y/x = 2/5.

Step-by-step explanation:

The null hypothesis is that the probability of the home team winning is equal to 0.5, or 50%. The alternative hypothesis is that the probability of the home team winning is greater than 0.5.

The test statistic for this hypothesis test is the binomial test statistic, which is calculated as follows:

z = (p - 0.5) / √(0.5 × 0.5 / n)

where p is the sample proportion of home team wins, n is the sample size, and 0.5 is the hypothesized probability of a home team win.

In this case, the test statistic is calculated as follows:

z = (28 / 50 - 0.5) / √(0.5 × 0.5 / 50) = 2.41

The critical value for this hypothesis test is z = 2.33, which is the value of z that cuts off the top 0.01 of the standard normal distribution.

Since the test statistic (2.41) is greater than the critical value (2.33), we can reject the null hypothesis. This indicates that there is enough data to prove that the home team has a higher than 0.5 chance of winning.

In conclusion, the probability of the home team winning in a football game is greater than 0.5. This means that the home team has an advantage over the away team.

Step-by-step explanation:

The center of gravity of the gymnast is located at approximately (0.1596 m, 0.0371 m).  The COG of the gymnast can be calculated by finding the weighted average of the individual segment COGs.

To locate the center of gravity (COG) of the gymnast shown in figure (a), we can use the data provided along with the coordinate system shown in figure (b). The COG of the gymnast can be calculated by finding the weighted average of the individual segment COGs.

Let's calculate the x-coordinate and y-coordinate of the COG separately.

For the x-coordinate (xcg), we can use the equation:

xcg = (m1*x1 + m2*x2 + m3*x3 + m4*x4) / (m1 + m2 + m3 + m4),

where m1, m2, m3, and m4 are the masses of the arms, torso, thighs, and legs, respectively, and x1, x2, x3, and x4 are the x-coordinates of their respective COGs.

Substituting the given values:

xcg = (6.89*0 + 33.6*0.337 + 14.1*0.145 + 7.50*0.227) / (6.89 + 33.6 + 14.1 + 7.50).

Calculating this expression:

xcg ≈ 0.1596 m.

For the y-coordinate (ycg), we can use the equation:

ycg = (m1*y1 + m2*y2 + m3*y3 + m4*y4) / (m1 + m2 + m3 + m4),

where y1, y2, y3, and y4 are the y-coordinates of the respective COGs.

Substituting the given values:

ycg = (6.89*0.236 + 33.6*0 + 14.1*0 + 7.50*0) / (6.89 + 33.6 + 14.1 + 7.50).

Calculating this expression:

ycg ≈ 0.0371 m.

Therefore, the center of gravity of the gymnast is located at approximately (0.1596 m, 0.0371 m) in the coordinate system shown in figure (b).

c. the 3rd one  

Step-by-step explanation:

Answer:

Step-by-step explanation:

To find different possible pairs of dimensions for the floor of the garage, we can use the formula for volume of a rectangular prism:

Volume = length x width x height

Since we know the height of the garage is 4 meters and the volume is 96 cubic meters, we can rearrange the formula to solve for the length and width:

length x width = Volume / height

length x width = 96 / 4

length x width = 24

Therefore, the length and width of the garage floor must multiply to equal 24 square meters. Here are two possible pairs of dimensions for the floor:

Length = 6 meters, Width = 4 meters

If we choose the length to be 6 meters, then the width must be 4 meters to satisfy the formula length x width = 24. This would result in a floor with an area of 24 square meters.

Length = 8 meters, Width = 3 meters

Alternatively, if we choose the length to be 8 meters, then the width must be 3 meters to satisfy the same formula length x width = 24. This would also result in a floor with an area of 24 square meters.

In both cases, we have found pairs of dimensions for the floor that satisfy the given conditions.

Answer: See explanation

Step-by-step explanation:

x=-(2-2*the square root of 6)/5, about 0.58

or

x=-(2+2*the square root of 6)/5, about -1.38

The values of the x from equation  \(5x^2+4x-4=0\) are  x = 0.5798 and -1.38.

Given that:

Equation:  \(5x^2+4x-4=0\)

To find the values of x that satisfy the equation \(5x^2+4x-4=0\), use the quadratic formula:

\(x = \dfrac{ -b \± \sqrt{b^2 - 4ac}}{ 2a}\)

Compare the equation with \(ax^2 + bx + c = 0\).

Here, a = 5, b = 4, and c = -4.

Plugging in the values to get,

\(x = \dfrac{-4 \± \sqrt{4^2 - 4 \times 5 \times (-4)}}{2 \times 5} \\x = \dfrac{-4 \± \sqrt{16 +80}}{10} \\x = \dfrac{-4 \± \sqrt{96}}{10}\\x = \dfrac{-4 \± {4\sqrt6}}{10}\)

So the solutions for x are calculates as:

Taking positive sign,

\(x = \dfrac{-4 + {4\sqrt6}}{10}\\x = \dfrac{-4 + {9.798}}{10}\\\)

x = 5.798/10

x = 0.5798

Taking negative sign,

\(x = \dfrac{-4 - {4\sqrt6}}{10}\\x = \dfrac{-4 - {9.798}}{10}\\\)

x = -13.798/10

x = -1.38

Hence, the exact solutions for the equation  \(5x^2 + 4x - 4 = 0\)  are x = 0.5798 and -1.38.

Answer:

243 cm³

Step-by-step explanation:

A cube has the same measure in length, width and height. So, we know that the area of the top face of a cube is 9 square centimeters, this means that

Length x width = 9 square centimeters

But, since length and width are the same, we have that they are equal to \(\sqrt{9} =3\) cms (since 3² = 9).

Thus, the volume of each cube is 3³ = 27 cm³

We are going to use 9 of these cubes to make a rectangular prism, therefore, the volume of this prism is going to be 9 times the volume of each cube.

Volume of prism = 9 (27) = 243 cm³

The value of v, using the angle addition postulate, is given as follows:

v = 18.

The angle addition postulate states that if two or more angles share a common vertex and a common angle, forming a combination, the measure of the larger angle will be given by the sum of the measures of each of the angles.

For this problem, we have three angles forming a ray, meaning that they have a total measure of 180º, and the smaller measures are given as follows:
