The area of the isosceles trapezoid is 72 square units.

A quadrilateral having at least one set of parallel sides and equal length non-parallel sides is called an isosceles trapezium. To put it another way, it is a trapezium whose two non-parallel sides are congruent. The trapezoid's parallel sides are referred to as the bases, and the segments that link the bases are referred to as the legs. The angle between the bases of an isosceles trapezoid determines its height.

Given:

[tex]\[d = 12 \quad \text{(length of one diagonal)}\][/tex]

Let;

[tex]\[h = \text{height of the trapezoid}\][/tex]

[tex]\[a = \text{smaller base of the trapezoid}\][/tex]

[tex]\[b = \text{larger base of the trapezoid}\][/tex]

Using the given information that the height and median are equal, we have:

[tex]Median(m)=\frac{1}{2} {(a+b)}\\\\Height(h)=\frac{1}{2} {(a+b)}\\\\2h=a+b ........(1)[/tex]

[tex]\[\text{Area} = \frac{1}{2} \cdot (a + b) \cdot h\][/tex]

[tex]\[\text{Area} = m \cdot h\] = h^2 ............(2)[/tex] (∵ [tex]Median(m)=\frac{1}{2} {(a+b)}[/tex] and m=h)

Now,

[tex]\[ d = \sqrt{h^2 + \frac{(a+b)^2}{4}} \][/tex] for isosceles trapezoid,

[tex]\[ 12^2 = h^2 + \frac{(a+b)^2}{4}}[/tex]

[tex]\[ 12^2 = h^2 + \frac{(2h)^2}{4}}[/tex]   (∵from eq (1))

[tex]\[ 12^2 = h^2 + {(h)^2}}\\ \\144= 2h^2\\\\h^2=72 ..........(2)[/tex]

Lastly, we may change the values of "a," "b," and "h" in the following formula to find the area as;

[tex]\[\text{Area} = \frac{1}{2} \cdot (a + b) \cdot h\][/tex]

[tex]\[\text{Area} = \frac{1}{2} \cdot (2h) \cdot h\][/tex]

[tex]\[\text{Area} = h \cdot h\] = h^2 = 72 sq units[/tex]

The answer is that it depends on the specific countable sets being considered and how they are being combined.

The union of countably infinite sets can be countable, as in the case of the union of all positive integers and all negative integers, which is also countable.

However, the union of countably infinite sets can also be uncountable. For example, consider the union of all the intervals [n, n+1) for n = 1, 2, 3, .... Each of these intervals is countable (since it contains all the real numbers between two integers, which is a countable set), but the union of these intervals is the uncountable set of all real numbers greater than or equal to 1. Therefore, the union of these countably infinite sets is uncountable.

This is the quotient

Let's call the number of months that it takes Pablo to save $700 as "m". The amount of money Pablo has saved after "m" months can be represented by the equation:

y = 200 + 125m

where y is the total amount of money saved after "m" months.

To find the number of months it will take Pablo to save $700, we can set y equal to $700 and solve for m:

700 = 200 + 125m

500 = 125m

m = 500 / 125 = 4

So it will take Pablo 4 months to save $700.

The equation in slope-intercept form is:

y = 125m + 200

where m is the number of months and y is the total amount of money saved. The slope of the line is 125, which represents the amount added to the savings each month, and the y-intercept is 200, which represents the initial amount of money Pablo received for graduation.

The solution of the equation is,

⇒ x = - 2/3

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 5³ˣ⁻² = 125²ˣ

a) Now, We can solve the expression by using change of base formula:

⇒ [tex]log_{b} y = \frac{log y}{log b}[/tex]

Hence, We get;

⇒ 5³ˣ⁻² = 125²ˣ

⇒ 5³ˣ⁻² = 5⁶ˣ

Take log both side we get;

⇒ log 5³ˣ⁻² = log 5⁶ˣ

⇒ (3x - 2) log 5 = 6x log 5

⇒ (3x - 2) = 6x

⇒ - 2 = 6x - 3x

⇒ - 2 = 3x

⇒ x = - 2/3

b) Solve for another method as;

⇒ 5³ˣ⁻² = 125²ˣ

⇒ 5³ˣ⁻² = 5⁶ˣ

By comparing,

⇒ 3x - 2 = 6x

⇒ 3x - 6x = 2

⇒ - 3x = 2

⇒ x = - 2/3

Step-by-step explanation:

The mean distance that the ball was thrown is approximately 38.92/12 = 3.24 feet.

To find the mean distance that the heavy ball was thrown, we need to calculate the sum of all the distances and then divide by the total number of throws:

(20+25+25+31+33+34+41+41+45+50+56+67)/12 = 467/12 ≈ 38.92

So, the mean distance that the ball was thrown is approximately 38.92/12 = 3.24 feet.

This means that on average, the ball was thrown a distance of 3.24 feet. However, it's important to note that the mean can be influenced by outliers, which in this case is the one throw of 6.7 feet.

So, while the mean is a useful measure of central tendency, it's important to also consider other measures such as the median and mode to get a complete picture of the data.

The mean is the sum of all the values in a dataset divided by the total number of values. It provides an estimate of the central location of the data and can be a useful summary statistic for describing a dataset. However, the mean can be influenced by outliers, which are values that are significantly different from the rest of the data.

In this case, the one throw of 6.7 feet is an outlier because it is much further than any other throw, and it will increase the mean value.

For this reason, it's important to consider other measures of central tendency such as the median and mode. The median is the middle value in a dataset, and it's not affected by outliers. The mode is the value that appears most frequently in a dataset and can provide useful information about the typical or most common value in the data.

By considering all three measures (mean, median, and mode), we can get a more complete picture of the data and make better inferences or conclusions about it.

2. Simplify the equation: r = (198/4π).

3. Calculate the value of 4π: 4π = 12.57.

4. Divide 198 by 12.57: r = 15.75.

5. The radius of the ball that holds 66 cubic centimeters of air is 15.75 cm.

Answer:

Step-by-step explanation:

To find the radius of a sphere that holds 66 cubic centimeters of air, we can use the formula provided in the question:

r = (3v/4π)

where v is the volume of the sphere. We are given that the volume of the sphere is 66 cubic centimeters, so we can substitute this value into the formula:

r = (3 x 66) / (4 x π)

Simplifying this expression:

r = 198 / (4π)

Using a calculator to evaluate this expression:

r ≈ 15.8267

The answers are a) OL = 46.2, CT = 92.4, ST = 41 and LT = 46.2

b) parallelogram ABCD is a rectangle.

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.

a) Given that, the flag of Scotland is a rectangle with white stripes as the diagonals. In rectangle SCOT, SO = 92.4, and CO = 41.

We need to find the measure of CT, OL, ST and LT,

We know that, the diagonals of a rectangle bisects each other and are congruent, and its opposite sides are equal,

Therefore,

OL = SO/2 = 92.4/2 = 46.2

CT = SO = 92.4

ST = CO = 41

LT = OL = 46.2

b) Given are vertices of parallelogram, A(-6, -2), B(-3, 3), C(2, 0), D(-1, -5), we need to verify if this is a rectangle or not,

Since, the diagonals of a rectangle are congruent, so, we will find AC and BD and see if they equal or not if equal then it is a rectangle.

Distance between two points is =

D = [tex]\sqrt{(x_{2}-x_1)^2+(y_2-y_1)^2 }[/tex]

AC = √(2+6)²+(2)² = √68

BD = √(-1+3)²+(-5-3)² = √68

∵ AC = BD, therefore, parallelogram ABCD is a rectangle.

Hence, the answers are a) OL = 46.2, CT = 92.4, ST = 41 and LT = 46.2

The area of a rectangle is given by the product of its length and width. Therefore, the area of the rectangle is:

A(x) = L(x) ⋅ W(x) = 2x(8x^2 - 4x + 1)

Simplifying the expression, we get:

A(x) = 16x^3 - 8x^2 + 2x

Therefore, the answer is (D) (L ⋅ W)(x) = 16x3 − 8x2 + 2x.

The measure of the central angle subtended by minor arc ab, to the nearest degree is 67.

A minor arc is a part of a circle that is created by two points on the circumference of the circle.

To find the measure of the central angle subtended by the minor arc ab, we need to use the formula for the circumference of a circle, which is C = 2πr. The length of the minor arc ab is 12 feet, which is a part of the circumference of the circle. So, we can write an equation:

12 = C * (arc ab / C)

where C is the circumference of the circle and arc ab is the length of minor arc ab. We know that the radius of the circle is 10 feet, so we can find the circumference of the circle using the formula for circumference:

C = 2πr = 2π * 10 = 20π

Substituting the value of C in the equation above, we get:

12 = 20π * (arc ab / 20π)

Dividing both sides of the equation by 20π, we get:

12 / 20π = (arc ab / 20π)

We can now find the central angle subtended by the minor arc ab by using the formula:

Central angle = 2 * arctan(arc ab / 2r)

Substituting the values, we get:

Central angle = 2 * arctan(12 / (2 * 10)) = 2 * arctan(0.6)

Using a calculator, we can find that the value of arctan(0.6) is about 33.7 degrees. Hence, the central angle subtended by minor arc ab is:

Central angle = 2 * 33.7 = 67.4 degrees

Rounding off to the nearest degree, we get that the central angle subtended by minor arc ab is 67 degrees.
